COPIER > ADJUST > EXP-LED
Sub item Description Level
PRE-TR Use it to enter the output adjustment value of the pre-transfer exposure.
range: 20 to 80 [Default: 50]
This item is available only for Japanese models, not for models for outside Japan. (Because it is specified not to light the pre-transfer
exposure for models for outside Japan. Thus, although the value is changed, the setting of the pre-transfer exposure LED output remains
OFF.)
- Do not use with the normal service.
- By setting the value larger, the degree of drum separation fault decreases whereas the degree of toner scattering image increases.
MEMO:
In case re-transfer/white spot at the leading edge occurs due to the drum separation fault, select COPIER > OPTION > BODY >
ACFRQNY/ACFRQ-R/ACFRQ-T, and increase the degree of foggy.
