MX3500N – MX4500N – MX3501N – MX4501N
2. Description
Black stripes may be generated on the reverse of copied paper.
This symptom is caused by the following mechanism: a burr on the rear side of the BK
LSU slit of the intermediate base plate (P/G No.21-25 or 20-25 CPLTM6539FC01) lifts the
LSU shutter (P/G No.21-3 or 20-3 PSHT-0107FCZZ) mounted on the intermediate base
plate and makes contact to the DV guide D BK (P/G No.22-21 or 21-21
PGIDM2131FCZZ). This disables the LSU shutter (BK) to be closed and laser beams
emitted through the LSU self-adjustment operation are exposed to the drum.
3. Action
For the field, take actions to grind the DV guide D BK contact spots by 0.5 mm.
For the production, we are erasing burrs on the intermediate base plate, if any, from April
2007.
DV guide D BK machining spots
Note) If grinding burrs on the intermediate base plate for the field, chips may fall down to
cause harmful effects. Be sure to take actions to grind the DV guide D BK contact
spots by 0.5 mm.
