Item Explanation
Around the
Drum Charge Wires/
Wire Cleaner/
Charge Grid Dirty charge wires may cause uneven image density.
They should be replaced at regular intervals.
End Blocks Toner tends to accumulate on the corona end
blocks, this can result in a high voltage leak. Clean
end blocks at regular intervals.
Drum Grounding
Terminal Too much drum grounding terminal deterioration
causes poor drum grounding. This results in dirty
backgrounds and drum potential sensor calibration
errors.
QL If toner accumulates on the QL, a dirty background
or a repeating negative image may result.
Clean the QL at regular intervals.
PTL If paper dust or toner accumulates on the PTL filter,
its efficiency may be reduced. This can cause toner
to be reattracted to the drum during transfer,
reducing image density. Clean the PTL filter at
regular intervals.
ID Sensor If too much paper dust or toner accumulates on the
ID sensor, the toner density cannot be controlled
correctly. This results in light copy or over toning.
Clean this sensor at regular intervals.
Erase Lamp If toner accumulates on the erase lamp, a dirty
background may occur in the erased area that
becomes progressively worse in long copy runs.
Also this affects sensor pattern detection, causing
incorrect toner density and exposure lamp control.
Clean this lamp at regular intervals.
Cleaning Blade A dirty or worn out cleaning blade will cause black
lines on copies or scratches on the drum. The blade
must be replaced at regular intervals.
Cleaning Brush A worn out cleaning brush will not clean the drum
surface effectively, resulting in a dirty background
and damage to the cleaning blade. Replace at
regular intervals.
Toner Collection
Bottle If the toner collection bottle becomes full, a service
call condition occurs and copying is prohibited.
Empty the toner collection bottle at regular intervals.
Pick-Off Pawls After long usage, the point that touches the drum
becomes worn and the area contacting the drum is
increased. This may cause drum filming, resulting in
vertical gray lines on the copy image.
Development
Unit Developer The tribo-chargeability of overused developer
decreases. This results in toner scattering.
Developer must be replaced at regular intervals.
Bias Terminal Less lubricant increases the friction between the bias
terminal and the bias receptacle. This may
deteriorate the terminal.
