Exposure head error - Исправление ошибок и поиск оптимальных решений проблем

I have a screen ctp plate rite. I have a problem and i coudnt soleve it. When i open the machine and start to initialazing machine give a error E4e0b : expoure head error. Whe i press detail it give me irregular 5 v power suplly also sometimes irregular -15 v power ssupply. Is there anyone seen like this problem?

Please change the cables from the power supply to the head. It is a common problem for the old Screen devices.

More to it than just a cable. I need you to check a couple things before replacing the cable.

Thank you for your replay. I check the cable and I saw bite on the cable But I measure the cpu card and I saw the all voltage right. What do you suggest next? What should I check?

Going in depth with this problem- the real problem is the voltage drop when the machine starts exposure. You can measure the voltage of the power supply and it could be ok, but… the head also measures the voltage and if it is out of the limit, the ctp generates this error. It is also possible to upgrade the FPGA of the head. For all of these you need a qualified Screen engineer, There is a big risk to do something wrong.

We have excessive current on board 2 and 4. I change CPU, head driver board and moder board same error. I check all the board on another machine they all work well. I check all the power voltage they are all correct. Please help me

measure the voltage at the 24V power supply terminals, adjust

We currently have a Heidelberg Topsetter 74 plate outputter. Just two days ago a warning appeared which said «Exposure Head Error — A command was sent to the exposure head but no answer was returned». This problem got progressively worse and we are now unable to output SM52 plates. I have to add here that we are still able to output other sizes of plate and that this problem is confined to SM52 plates. An engineer attended and was unable to narrow down the problem and we now face the expense of replacing ever more expensive parts until the problem is resolved. If anyone has experienced this problem before I would most definitely welcome their advice. Many thanks.
I discussed your problem with one of our 2nd level support engineers. While he admitted it was difficult to troubleshoot the problem based on the information provided he felt there may be an issue with the cable which supplies information to the imaging head.
Thanks for taking the time to enquire about my problem Paul. Much appreciated. As it happens our first attempt at rectifying the problem will be to replace the cable you mention. Hopefully this’ll be successful.
Replaced the cable which supplies information to the imaging head and problem solved.
Just reading your post re problem solved. I have the exact same problem here on our Topsetter P74. Were you able to replace the cable yourself or did it require an engineer? If you managed it yourself, could you let me know where the cable is located etc. so I can look into fixing our problem.
Many Thanks
Andy
Hi Andy.
The problem we had is getting on for two years ago and we now have a Magnus 400, that said however I seem to remember that an engineer replaced the cable that solved the problem. As many of the Heidelberg engineers were laid off there are a few out there that work freelance. I might be able to get a phone number for you if you’d like but not sure if it’d be any use if you’re located outside London. Rest assured however that the problem is the cable so you don’t have to worry about other expensive parts.
Regards.
Jem.
Hi Jem
I will speak to an engineer (ex Heidelberg) who we know and ask him to come and sort.
Many thanks for your speedy reply and information, its very much appreciated.
Regards Andy

Фотографии проявки. Пластина проходит слева направо.
Красный, зелёный, синий и оранжевый — это области соответственно проявителя, воды, гума и сушки.
На второй фотографии снята крышка, минимизирующая контакт проявителя с окружающим воздухом (имхо), также без неё уровень проявителя становится ниже.
На третьей фотографии показан проход бракованной и однажды проявленной пластины сквозь проявку. Новая пластина была бы синей до секции воды, где пробельные элементы смываются окончательно. Панчи уже успели зайти в секцию гума.

Kool, вы спрашивали город — Иркутск.
Я правильно смотрю на ровность линий при настройке Зума? Ведь вышенаписанное про «прямые линии — гуд, кривые — брак» — это лишь мои догадки.
Проблемы с вакуумом можно легко отследить, если вывести растр на всё поле — неравномерный прижим сразу будет заметен тёмными пятнами, не так ли?
«вызвать сервисников ЯМа» — я в курсе пословицы про гром и мужика, но выглядит нелогичным вызов сервиса, когда аппарат выдаёт пластины, с которых удачно печатаются тиражи. Цена вызова будет около 50-120 т.р, да?
Гораздо интереснее было бы самостоятельно выяснить, что некие диоды скоро неприемлемо снизят свои показатели. Куда смотреть?
Не сомневаюсь в возможностях и знаниях сервиса «Ям», но они не смогут оперативно помочь. «Звонок, чемодан, вокзал, Иркутск» в идеальном случае займёт сутки. А в реальности я бы думал о неделе. Имхо.
Вот была ситуация: E7e06: Exposure head error, –5 V power supply error.
Блок питания выдаёт очень хорошую норму. Помогло шевеление шлейфов на голове. Затраты времени — 3 часа простоя. Повезло. Что было бы, звони мы в московский сервис — не знаю. Может уложились бы в час, может в пару недель.
«поддержка со стороны компании, представляющих SCREEN официально — это намного лучше, чем вы там изучаете оборудование методом тыка» — безусловно. Просто не знаю, чем они меня поддержат. Можно вызвать на профилактику — приехали, осмотрели, почистили, смазали. Проведут лекцию по работе и периодическому ТО, вроде, «как не тратить деньги на сервис, и сделать простые вещи самому»? Люди делятся на умеющих и на способных научить, и крайне редко всё сразу — поэтому не надеюсь на обучение. Да и альтруисты редки. Возможно, что я неправильно смотрю на ситуацию.

Oh, I haven’t seen that one.

The one we get is a exposure head error. I spoke with a tech and he said it’s common. I guess the little brown and black wires that run from the power supply to the exposure head get too much tension which leads the head to believe the power supply is cutting out. It’s a phony error but it kills the plate halfway through anyway. It’s good most of the time now that I re-routed the wire but it still gives me some trouble every couple of months or so. I was hoping you had a creative fix.

Otherwise, I love the PTR

We’ve seen plenty of exposure head errors at my shop. I’m running a Dart (PT-R 4000 II). In our case, the techs chalk it up to humidity, or lack thereof, and the resulting static electricity. I believe they’re correct, since we usually get a lot more of these errors in the winter months. It has been better since we stuck a humidifier near the machine. They’ve also had us stick a box of Bounce dryer sheets in the machine to ward off static.

Otherwise the machine is rock solid. We paid for a service contract for a couple of years, but gave up on it. We’ve had the machine for almost 5 years now, and (knock on wood) haven’t had to replace a single diode. So, now we just get 2 PMs a year and pay time & materials.

As for service on the RIP, we run a Harlequin. I can’t imagine paying for a contract on that. I think I may have finally sold management on switching to Rampage soon (crossing my fingers), and if that happens, I’ll be sure to spring for their contract for at least 1 year.

I played for years and one day my father found weed in my car and got pissed and burned thousands of dollars of cards. Fucking BOXES. I had an undefeated 5 color deck that I spent a year building, all down the tubes.

Found weed then destroyed thousands of dollars of your stuff? That’s fucked up. It’s just a damn plant.

Up in smoke you might say

Yeah. He didn’t know. He thought they were some kind of evil tarot cards or something. Saw me going down a path he didn’t like. He has a temper. Hot headed Sicilian, ya know? He felt bad when he found out what they were. I’m still pissed. That’s all I did for like 4 years.

I signed up for another year of tech support for Rampage.
Fuji gave us some crazy proposal for our Platerite and Processor. We passed on it.
I’m still second guessing myself on the Rampage support.

Son you better watch your back when a poor man gets the blues.

I’m getting Tubehead error 70 intermittently. Usually a restart clears the error, but Xray techs would take an exposure then the next one you get tubehead error 70. I have blown out the dust to collimator blades, lubed rails & gears to collimator blades, checked connections & voltages to Tubehead motor drive bd- good. The manual talks about the tubehead processor bd that plugs into motor drive bd. Called Lorad, you need a PO to talk to tech support. Has anybody run across this tubehead error 70 before & what corrected the issue ?? Thanks for any help.

Almost 100% of the time cleaning greasing and properly assembling the collimator fixes this issue. Take the trays down make sure you have all the old grease off and when regreasing a little goes a long way and make sure your using tue correct grease, using the wrong grease can also cause it to bind. Also when putting it all back together dont crank on the screws just anig them up lightly, overtightening will also cause it to bind. Good luck

I concur with jay672. On one occassion I found the filter frame mounting bolts had loosened and were interfering with motions, and once a dealer tech said he walked in to a site where a new tech was being trained, there was a lot of comression cycles and the lamp was heating things up to the point of making things sluggish. But as stated above, make sure *all* the old grease is cleaned off. Run the collimators by hand several times to to work it out of the block, get right into the grooves and get the screws shiny, also the rails. Take your time and be very thorough, don’t scratch anything and don’t leave any lint or fibres behind, Kim wipes are best if you’ve got them. The proper grease is NSK PS2 bearing grease (https://cnc-specialty-store.com/grease-lubrication/nsk-grs-ps2-grease-80g), at least, that’s what I saw in the dealer tech’s tool case and he recommended.

You could also check the motor and board connections. They use the type of pin that makes contact by cutting into the wire insulation, and they can work loose over time. Make sure all the wires are fully seated into the pins, and un/plug the connectors a few times to polish up the contacts to the board’s pins.
