1-1. Precautions in Maintenance

1-1-1. Notes on repair

Be sure to turn the power off and unplug the power cable from the main body inlet before starting work.

To prevent the ink from getting into your eyes, be sure to wear safety goggles and gloves when cleaning the print head or replacing the S pump L assembly or if the ink is anticipated to scatter. If the ink sticks to your hand, the skin may be get rough and dry.

Danger of explosion if battery is incorrectly replaced.

Replace only with the same or equivalent type recommended by the manufacture. Dispose of used batteries according to the manufacturer’s instructions.

Take sufficient care so that leaked ink does not adhere to other parts. Ink droplets attached to

FPCs or connectors may cause shortcircuit or a bad electric contact at inserting/removing a damper, thereby the ink discharge trouble or breakage of head/PCB may occur.

Properly and carefully connect the FPC cable of the slider PCB from the HDC PCB according to the connector number. Failure to do so may cause a breakage of the PCB because of shortcircuit of the power supply.

Pay sufficient attention on arrangement of 2 FPC cables connecting the head relay PCB to the head. Wrong arrangement of the FPC cables causes short-circuit of the power supply.Do not turn off the power during firmware upgrading. Doing so may disable restarting.

Observe the following precautions in maintenance work.

Be sure to fully understand precautions given in “For safe operation” in the operation manual for the JV5 series.

Some error conditions observed may be due to misoperation. First judge whether or not the error condition is caused by misoperation.

Provide adequate space for the maintenance work.

When performing tests with the electrical circuit box open, be careful not to receive an electric shock from any live part and not to drop screws or any other parts into the circuit box.

Take care to avoid insufficient insertion or skewed insertion of any connector or FPC.

In the case where it is necessary to conduct maintenance works with the power on, carefully observe the movement of the head. (Keep any part of your body away from the moving parts.)

Shift the media (in the X-direction) and the head (in the Y-direction) using the jog keys. If it is

necessary to shift the paper and the head by hand with the power turned off, exercise care to shift them slowly.

Do not tilt the printer with the ink cartridges filled with ink. Doing so can give rise to leakage of ink.

In principle, the following procedures should be taken in prior to the transportation and the transportation should be conducted using exclusive packaging members.

Do not tilt the printer with the ink cartridges filled with ink. Doing so can give rise to leakage of ink. Discharge ink from the tube in accordance with the description given under “Discharge cleaning” in the maintenance.

1.Detach the waste ink tank.

2.Execute “BeforeMovingIt.” of the machine.

3.Fix the head with the head stopper. (As for the detail, see Setup Guide)

1-2

Precautions in Maintenance

If the main unit is removed from the legs and placed directly on the floor, be careful of the following points.

•Unplug the take-up unit power cord.

•Remove the ink waste tank and the fitting bracket.

(Plug the tube up with a cloth to prevent ink from spilling over.)

1-1-2. Preliminary checks

Before starting work, make sure that the following conditions are all met.

The following conditions for the power supply system are all met:

•The power supply voltage must be within the specification limits.

•The printer must be grounded properly.

•The power cable must be free from damage, broken wire, etc. Many cables must not be connected to one outlet.

Make sure that the printer is not located under any of the following conditions:

•In a place where the printer is exposed to direct sunlight.

•On an inclined surface.

•In an environment of too high or low temperature, or too high or low humidity, or in a place where temperature or humidity varies significantly.

•In a place where vibration occurs.

•In a place where the printer is exposed to direct air flow from an air conditioner or the like.

•Around a place where flame is used.

•In a dusty atmosphere.

•Around a place where strong electromagnetic waves are generated.

The media (sheets) to be used must conform to the specifications.

Operation Principle

2-1-6. Ink System

Ink Supply Control

Ink filling method of JV5 is a suction system with roller pump, a pressure damper with a self sealing

valve is used. Ink supply at drawing is a siphon supply. The sealing valve is opened by discharging pressure reduction to supply ink, and when the damper ink chamber is filled, the sealing valve is closed. The ink path pressure at carriage moving conveyed to the meniscus of head is eased by the sealing valve.

Longer consecutive drawing time than conventional products and replacement of cartridges during the drawing are allowed by toggle switching of 2 cartridges for 1 supply path.

During the ink end cartridge replacement, in order to avoid dehydration of ink supply system, a WARNING is displayed if a cartridge is not placed for more than 10 minutes.

A supply valve is placed for each cartridge to supply ink at the supply valve OPEN. The supply valve

is usually in CLOSE state, and when ink supply is necessary, the supply valve turns to OPEN state. Ink supply is conducted at discharging operation (drawing and flashing) and suction operation (cleaning and filling). The supply valve is not opened for a cartridge having an error not to supply ink.

2 types of LED (Green: control LED / Red: Error LED) are placed for each cartridge to allow a user to check a state of cartridge in visual.

JV5 switches the supply valve at occurrence of “INK NEAR END” or “INK END” in the cleaning to use a cartridge having smaller residual quantity. As for details, see “ Ink wear-up cleaning” (P.2-17 ).

Device configuration

The device configuration of ink supply path is shown below.

Flow of the ink supply control

The ink supply control flow can be divided as the followings.

1.Error check of the cartridge.

2.Selection/determination of a supply cartridge (depends on a state of the cartridge).

3.Updating of each LED (depends on a state of the supply/error cartridge).

4.Supply valve open/close operation of the cartridge selected in “2” with a valve operation instruction.

Error check of a cartridge

The error check of a cartridge is executed periodically (every 30 ms) to select a supply cartridge according to an error state and ink residual quantity.

The supply cartridge notifies being under control with lighting the control LED (Green). The error cartridge lights/blink the error LED (Red) to urge replacement of cartridges.

A valve of the cartridge indicated by lighting of the control LED is opened with a valve-open instruction.

When an error occurs in a supply cartridge while the valve is opened (at drawing or at cleaning), if there is a cartridge which can supply ink, the valve is switched to continue the operation, if a supply cartridge is removed, drawing is aborted and cleaning is terminated to return to the local state.

Selection/determination of a supply cartridge

As ink is supplied by toggle switching of 2 cartridges for 1 supply path in JV5, a supply cartridge should be selected. The followings are selection conditions of a supply cartridge.

a)When there is a cartridge having an error in 1 supply path.

•If another cartridge can supply, the cartridge is selected.

•The selection conditions depend on occurrence of an error, contents of the error and ink supply timing. The ink supply is executed at discharging operation (drawing, flushing and so on) or at suction operation (cleaning and filling).

The followings are cartridge selection conditions. As for errors, see “ Ink system error monitoring” (P.2- 15 ).

Ink residual quantity control

Residual quantity of cartridge ink is calculated by subtracting ink consumption quantity obtained by calculation of number of ink shot times of drawing and flashing and ink suction amount by cleaning and filling from the ink residual quantity.

When ink residual quantity is updated, writing to the ink IC chip is executed.

A cartridge error is issued according to the residual quantity.

Calculation of ink consumption quantity

The followings are calculation of ink consumption quantity at drawing, cleaning etc.

a)At drawing and flashing (ink discharging)

Ink consumption quantity at ink discharging is calculated with counting the number of ink shot times.

In JV5, as each dot size is counted at unit of each nozzle array, Small, Middle, Large, smaller error between actual measured value and calculated value can be expected.

b)At cleaning and filling (ink suction)

Ink consumption quantity at each operation is shown in the table below.

Type		Ink consumption quantity in 1
	supply path [cc]


Soft cleaning		0.4

Normal cleaning		1.1
High power cleaning		8.3

Maintenance filling		33.7
Initial filling		Main suction	69.2

		Cobble filling	15.7
Initial filling		Main suction	69.2
(At replacement)

Updating of ink residual quantity

The ink residual quantity is updated at the following timings, and written in the ink IC chip.

Updating timing	Conditions

At pre-capping operation	When ink is consumed by drawing or flashing.
	Mainly at capping after completion of drawing.

At completion of cleaning and filling operation	Ink is consumed by cleaning and filling.

	Initial filling is not allowed (drawing and cleaning is allowed).

Cartridge ink end	Error arising timing:Arising at consumption of predetermined quantity after the near end
	detection.
	Restrictions after arising of an error:Drawing and initial filling are not allowed (cleaning is
	allowed).
Residual quantity 0 cartridge	Error arising timing:Arising at residual quantity 0 after arising of ink end.
	This error may arise only after cleaning by the ink wear-up cleaning.
	Restrictions after arising of an error:
	Drawing, initial filling and cleaning are not allowed.

Cartridge error	Error arising timing:Arises when the ink end does not arise even if ink consumption quantity
	exceeds about double of ink cartridge capacity*.
	Restrictions after arising of an error:
	Drawing, initial filling and cleaning are not allowed.

* Arises at 220cc cartridge: 400cc, 440cc cartridge: 800cc.

Ink wear-up cleaning

The purpose of this cleaning is subduing ink consumption of a normal cartridge by using residual ink of a cartridge having “Cartridge near end” error or “Cartridge ink end” error by priority.

When one cartridge is normal at starting of cleaning, residual ink side is sucked and after suction, switched to the normal cartridge to continue cleaning.

When residual ink is used up (soft counter), “Residual quantity 0 cartridge” error is arisen to disable the cartridge.

Ink wear-up cleaning control is only effective in the normal cleaning, and it can not be executed at other cleanings or at initial filling.

Color Inkjet Printer JV5-130S/160S

Ink Suction and Discharge Control

Outline of control

Suction and discharge of ink is driven by roller pumps (ink suction pump), 1 pump is allocated to

every 2 heads.

Suction and discharge are executed at each pump (at each head is impossible because of the configuration).

2 sensors in the waste ink tank prevent ink troubles caused by an installation miss, ink over flowing

and so on.

At sensor detection, operations conducting ink discharging such as drawing, cleaning, filling and so on, are restricted.

In order to avoid clotting of ink in an waste ink path tube from inside of a cap to the waste ink tank,

automatic cleaning mechanism (pump tube cleaning) is equipped.

An exclusive pump sucks cleaning fluid from installed cleaning fluid tank to clean inside of the tube (Executed at Standby in Power ON or Sleep in Power OFF.)

In order to avoid clotting of ink adhered on a wiper, a wiper cleaning mechanism is equipped. Cleaning fluid is supplied on the wiper at a solenoid for wiper cleaning OPEN.

		Set value: ES3 Sol, HS Sol

2	Selection of number of	A set value is selected among values shown below.
	colors	Set value: 4-Color (MCYKKYCM), 6-Color (MCcKYCMm)
3	Filling of filler liquid	Insert a filler liquid cartridge in a slot to be sucked
		(As 8 filler liquid cartridges are initially attached, use those cartridges with swapping in order of
		odd number slots → even number slots.)
		1. Suction to a coupler (odd number slots):
		Insert filler liquid cartridges into odd number slots (x8) and suck the liquid to the coupler.
		Sucking the liquid to the damper (head) (even number slots):
		Taking out filler liquid cartridges in odd number slots and insert them into even number slots
		(x8), suck the liquid to the damper (head).
		If there is an occurrence of warning* in a filler liquid cartridge, suction is not conducted.
		If there is an occurrence of warning in waste ink tank, suction is not conducted.
		If a warning related to waste ink tank is detected during sucking, sucking is stopped and the
		filler liquid sucked again.

4	Cleaning fluid filling	Inserting ink cartridges into all slots and ink filling is conducted.
		1. Filling to the coupler
		In case of cartridges in the same supply system, valves are opened in order of 2 → 1, ink is
		filled to the coupler.
		2. Filling to the damper (head).
		If a warning occurs in the ink cartridge, filling is not conducted.
		If a warning occurs in the waste ink tank, filling is not conducted.
		If a warning related to the cartridge occurs during filling to the coupler, filling is stopped and
		ink filling is executed again.
		If a cartridge warning occurs during filling to the damper (head), filling is continued with
		replacing cartridges.
		Filling is stopped when ink supply fails in one supply system.
		If a warning related to the waste ink tank is detected during the filling, sucking is stopped and
		ink filling is started again.
5	Cleaning fluid filling	Filling of exclusive cleaning fluid for wiper cleaning, pump tube cleaning.
		Insertion of the cleaning fluid cartridge into a slot is confirmed and filling is conducted.
		If a warning occurs in the cleaning fluid cartridge, filling is not conducted.
		If a warning occurs in the waste ink tank, filling is not conduct.

* As an IC chip is not placed in a filling liquid cartridge, it is recognized that IC chip read error means normal.

Operation Principle

NCU LD RESET

Initialising LD current consumption value.

Current value increases gradually according to the operation of NCU. Initial value of the current value is stored in the device and when the value exceeds the predetermined value, the error (ERROR161) to urge the user to replace the LD sensor unit with a new one is displayed.

If LD current consumption value exceeds 109% of the initial value:

ERROR161 NCU EXCHANGE

NCU can be used

If LD current consumption value exceeds 110% of the initial value:

ERROR161 NCU CONSUMPTION

NCU can not be used

This function is effective only at the MAINTENANCE OPEN, and required to be executed at replacement of LD sensor units.

The4 NCULD reset should be executed in the local idling state (a state that initial operation has been completed and capped).

At normal end (reset complete)	: “ RESET COMPLETION ”
At error (reset failure)	: “ !! RESET FAILURE !! ”

(Make sure that the machine is in the local idling state, and then execute the reset again.)

HEAD ID

Contents:Head ID input of JV-5 is automatically executed by the system.

The head memory PCB Assy is equipped on the head unit Assy (M007034, IH47V Head Unit Assy), the ID information is written in the head memory Assy.

Head ID is for compensating differences of discharge amount of ink among each head. A label on which a compensation value (ID) is written is attached on a head at shipping.

Storing the ID in the Parameter of JV-5 makes print quality constant.

Manual input of the ID information is required in the following cases.

In a case that the ID information is not stored in the head memory PCB Assy.

“ HEAD ID Un-Input ” is displayed on the panel (at the power ON)

In a case that the head ID is not identical to the ID information in the PCB Assy. (when a PCB of another head is placed, for example).

As the error is not displayed on the panel, taking care is required at replacing. Manual ID input is recommended if there is a doubt on agreement between the ID of a head and the ID information in the memory PCB.

When the head ID is changed, never forget to turn the power OFF with the remort switch (the front side power switch) to write new ID information in the head memory. (If the power is turned OFF with the main power SW (back side), as contents of the headmemory are not updated, changing of IDs is not reflected.

В виду популярности данной темы разберем основные моменты технического обслуживания экосольвентного принтера Mimaki.

Также коснемся основ работы с печатным оборудованием, а именно оптимальных условий для работы вашего принтера.

Работы проводились с популярной моделью JV-150, однако принципы общие практически для всех принтеров с данной компоновкой.

В данной статье постараемся ответить на несколько вопросов:

0. Оптимальные условия работы для оборудования.

1. Как часто необходимо ТО принтера?

2. На какие узлы принтера обратить внимание при проведении чистки, обслуживания принтера?

3. Что влияет на качество печати?

Ответы на данные вопросы будем раскрывать по мере проведения работ.

1. «Чистота — залог здоровья», Стабильность, Температура, Статическое электричество

Приступим к обслуживанию:

Очищаем поверхности принтера от пыли, грязи — стол, верхняя планка, внешние поверхности принтера.

При очистке стараемся не раздувать пыль во все стороны, которая гарантированно осядет на ленту растра, и электронику, что может привести к двоению при печати или более печальным последствиям.

Также стоит обратить внимание на полосы клея, которые остаются от материала – на столе принтера и роликах.

P.S.

Вообще, содержать в чистоте и порядке оборудование, ежедневно очищать от пыли поверхности и проводить ежедневную влажную уборку в рабочем помещении — это норма, придерживаться которой стоит не только ради соблюдения гарантийных условий производителей оборудования, но и для стабильности и безотказной его работы в целом.

Стабильная и оптимальная температура в помещении для принтера: около 20-26 градусов Цельсия. Главное, чтобы не было резких скачков и ухода в экстремально высокие (30) или экстремально низкие (17) температуры. Тогда и материал будет вести себя предсказуемо и режимы печати выбранные для конкретных материалов не придется постоянно менять и подстраивать.

Что касается такого «врага» как статика:

— влажность в помещении должна быть в диапазоне 55%-75%

— обязательно заземление всея и всего. И именно заземление, а не «зануление» Также — использование сетевого фильтра, а в идеальном случае — источника бесперебойного питания, даст Вам существенный плюс при работе с принтером, при наличии нестабильности электропитания.

— правильное хранение материалов для печати — как минимум — не храните материалы возле батарей отопления.

2. Обслуживание

Продолжаем процедуры:

— Очистка направляющей рельсы от пыли, грязной смазки.

— Очистка грязи с торцов линейных подшипников. (на фото указано стрелкой)

— Смазка направляющей рельсы специальной силиконовой смазкой.

После смазки прокатываем каретку в обе стороны и удаляем излишки силиконовой смазки, которые будут скапливаться на торцах подшипников, а также в позициях остановки каретки.

Благодаря данной процедуре линейный подшипник «проживет» гораздо дольше, двигатель «таскающий» каретку также будет меньше нагружен. Да и каретка, которая движется равномерно способствует повышению качества печати.

3. Очистка сдвоенного пластикового шкива.

На данном станке есть особенность – сдвоенный шкив, который «таскает» каретку выполнен из высокопрочного пластика, и шаг зубьев небольшой.

Если помещение далеко от идеала, к примеру — пыльное, часто печатается баннер, с краёв которого выпадают лохмотья волокна, то пыль или нитки волокна от баннера, ремнем прикатывается к шкиву, спресовывается в субстанцию схожую с камнем…

Дальше под ремнем образуется бугорок – неровность об которую ремень очень быстро и очень сильно изнашивается с прорывом по центру (на фото трещины и разрывы). Также может происходить «гуляние» ремня по шкиву, что в свою очередь срывает стопорный кант на шкиве (на фото приведен пример того — как это бывает)

Сам ремень можно также протереть влажной (НЕ СПИРТ, НЕ СОЛЬВЕНТ), безворсовой тряпочкой, не задевая ленты растра расположенной непосредственно за ремнем.

4. Очистка ленты растра

Если при печати наблюдается периодическое двоение, печать стала нечеткой, линии по горизонтали шире чем по вертикали, происходит размытие, а все усилия по сведению и подстройке режима печати в Bi-Direction не приводят к желаемому результату, то проверьте состояние ленты растра.

Если она не залита чернилами и не повреждена, то очищаем её от пыли.

5. Зона парковки печатной головы.

Если со временем голова начинает плохо прочищаться – тест дюз показывает пропадание дюз, цвет «выбивает» при печати, то одной из причины является изношенная капа парковки. Она уже не может обеспечить плотное прилегание головы и создания достаточного разряжения помпой (насосом), благодаря которому чернила из демпферов подтягиваются в печатную голову.

Износ капы происходит не только из-за механических причин, но и на степень износа влияют также сами чернила, а точнее их сольвентная основа.

Износ капы парковки можно отследить по искривлению, искажению прилегающей к подошве печатной головы части.

Отмечу, что этот вариант один из многих и нужно также периодически заменять демпфера печатной головы. Демпфера имеют фильтр и со временем изнашивающийся клапан.

При износе демпфера происходит чернильное голодание и к голове также поступает меньшее количество чернил. Демпфера рекомендуется менять раз в 6 месяцев. Однако, на практике, при использовании качественных чернил, демпфер может прослужить гораздо дольше.

При замене, обязательно очищаем всю прилегающую зону от налипших, засохших чернил.

Все элементы должны двигаться легко и непринужденно – так как задумал производитель принтера.

Также не могу не отметить одну особенность модели:

Если Вы используете функцию отмочки дюз печатной головы (NOZZLE WASH), то со временем можете заметить, что даже при полном картридже сольвент не подается в капу в автоматическом режиме..

Вероятнее всего — произошло засорение промывочной системы и чернильный слив засох в трубке.

Нужно снять трубку, отсоединив её от электромагнитного клапан, от капы парковки и промыть сольвентом. Если засор не вымывается, то трубку лучше заменить.

Почему система, которая отвечает за чистоту забилась – спросите Вы. Все просто, как только в картридже с промывкой заканчивается сольвент, а оператор не заменяет картридж на новый (полный), он постепенно смешивается с чернильным сливом в трубке до такой концентрации, что намертво забивает оную.

При очистке зоны парковки не забываем и про мягкие спонжи, которые очищают каретку от накапливающихся капель на металлической основе. Данные спонжи можно просто заменить или, как минимум, промыть сольвентом, высушить и установить обратно.

Обязательно очищаем вайпер (резиночку смахивающую с головы капли чернил при прочистах). Если вайпер уже изношен — кромка искривлена,то он плохо удаляет капли с подошвы печатной головы.

6. Не забываем про нижнюю поверхность каретки.

Обязательно очищаем зоны вокруг печатной головы, сам металл каретки, а также металлические края печатной головки. Сам поверхность дюзной пластины лучше не трогать, а если образовалась грязь, которую нужно убрать, то делать это с максимальной осторожностью и смоченным в сольвенте спонжем.

7.После проведения чисток, замен и всех упомянутых выше манипуляций проводим настройку параметров печати:

В обычном случае достаточно проведения стандартной процедуры DROP POSITION CORRECT.

Данная процедура позволяет провести настройку, юстировку печати в режиме BI-Direction (печать в обе стороны). Если сведение в пользовательском режиме не помогает, то нужно проводить более сложные корректировки в инженерном режиме. (в данном случае рекомендуем обратиться к специалистам)

После запуска процедуры распечатывается таблица со штрихами и подписанными значениями для корректировки. Находим лучшее схождение полос, вводим корректировку в меню и… получаем идеальную печать.

На фото результат печати после всех произведенных манипуляций.

Перед печатью картинка была уменьшена в двое, т.е. там где написано шрифт 6 pt – размер символа в 2 раза меньше. (примерно 3 pt).

Режим печати: 720х1080, в режиме Bi-Diection (в две стороны)
