1) ADJUSTMENTS
The separation belt should contact the paper at a position 3.5 ± 0.5 mm inward from the
Copier-Front edge of the paper. Also, the width of the "no-image-area" formed by the De-
veloper Assembly scraper blade should be 7 ~ 8 mm. If either need adjustment, perform the
following:
a) If the "no-image-area" is wider than specification, slide the assembly frame toward the
copier-rear.
b) If the "no-image-area" is narrower than specification, slide the assembly frame toward the
copier-front.
c) After adjusting, make a few copies to check the width of the "no-image-area". If neces-
sary, perform a) or b) over again.
