Line No.5: White Lines Caused By Development Unit - Ricoh Pro C901 Technical Bulletin

Reissued:21-Apr-14
Model:
Aries-P1.5/C1.5
Line No.5: White lines caused by Development Unit (Clogged doctor gap)
Cause
a) Edge of the mylar attached to M0773457 (index #5 in Figure1 on the next page) is
torn and split, and is contacting the development roller. Due to this contact,
toner supply is blocked and sufficient amount of toner is not transferred to the
drum.
Note that M0773457 is attached with 2 different types of mylars. One has a round
edge and the other a straight and flat edge. (See the bottom photo on the next
page.)
b) Developer mixture is accumulated at the doctor gap, causing insufficient toner transfer
to the OPC drum
