Sharp ошибка 0306

При использовании любой техники время от времени могут возникать неполадки. Так, например, при использовании копиров, принтеров и МФУ Sharpмогут появляться различные ошибки, вызванные различными причинами. Об их возникновении пользователь информируется с помощью кода, которые выводится на дисплее принтера или другого используемого устройства. Коды ошибок Sharp вы можете идентифицировать с помощью приведенной ниже таблицы.  Выяснив причину сбоя в работе устройства, вы сможете устранить ее самостоятельно (например, если произошло замятие бумаги, отсутствует бумага в лотке) либо обратиться в сервисный центр по обслуживанию и ремонту Sharp, если код ошибки сообщает о серьезной поломке.

CD SECTION

Adjustment

Since this CD system incorporates the following automatic

adjustment functions, readjustment is not needed when

replacing the pickup. Therefore, different PWBs and pickups

can be combined freely.

Each time a disc is changed, these adjustments are

performed automatically. Therefore, playback of each disc

can be performed under optimum conditions.

Items adjusted automatically

(1) Offset adjustment (The offset voltage between the head

amplifier output and the VREF reference voltage is

compensated inside the IC.)

* Focus offset adjustment

* Tracking offset adjustment

(2) Tracking balance adjustment (waveform drawing 15-2

EFBL)

(3) Gain adjustment (The gain is compensated inside the IC

so that the loop gain at the gain crossover frequency will

be 0dB.)

* Focus gain adjustment
