8.11 Blank Spots in Dark Areas
The dark areas of the paper have large splotchy white spots.
Damp toner or paper or an over-exposed OPC drum can cause
these symptoms. Storing the EP-L cartridge in cold temperatures
or high humidity makes the toner damp and causes caking.
Prolonged exposure to room level lighting will damage the OPC
drum. Perform the following steps:
1. Inspect the condition of the high-voltage connectors that
connect the EP-L cartridge to the HVPSA.
2. Remove the EP-L cartridge and agitate according to the
direction on the cartridge.
3. Try some dry paper from the center of a new package.
4. Swap the EP-L cartridge.
If you suspect damp toner or a light damaged drum, try
storing the cartridge in a dark, dry, room temperature location
for a day or so. The OPC drum may recover and the toner
should dry out.
5. Swap the EP-L cartridge.
6. Swap the HVPSA.
8.12 Solid White Vertical Lines in Dark Areas
This symptom can be caused by an obstruction in the laser beam
path or by unevenly distributed toner in the EP-L cartridge.
Perform the following steps:
1. Remove and agitate the EP-L cartridge, as shown on the
cartridge label.
2. Look for foreign matter that can obstruct the path of the laser
beam.
3. Swap the EP-L cartridge.
