The laser beam is being blocked and is not reaching the OPC drum.
a. Check the LSU cover glass and clean if necessary.
b. Replace the cover glass if it is cracked or cannot be cleaned.
c. The LSU has something blocking the beam inside it and must be replaced. The LSU
cannot be opened and cleaned, it must be replaced.
212.
There is a foreign object behind the doctor blade in the developer unit that is preventing
the toner from reaching the developer sleeve. To verify this, examine the developer
sleeve. Look for a line of missing toner.
a. Replace the developer unit.
213.
The OPC drum has a defect in it that extends completely around its circumference.
a. The OPC drum has a scratch and must be replaced.
b. The OPC drum has an area of poor electrical characteristics and it must be replaced.
214.
If the streak does not appear on the OPC drum, there is a foreign object that is rubbing
on the unfused page.
a. Locate and remove the obstruction in the paper path that is somewhere between the
transfer charger and the fuser. This is usually a piece of paper that is touching the
paper and smearing the unfused toner. This is usually at the entrance to the fuser.
215.
There is something on the transfer corona wire or in the corona wire channel.
a. Clean any toner from the corona wire with the corona cleaning felt.
b. Remove any paper in the transfer charger channel.
220.
Wide white line (fuzzy edges).
221.
The printer has been operated with a low toner condition, resulting in an area of light
print. This can be seen by looking at the developer sleeve in the developer unit. If it
appears gray instead of black, the toner is low.
a. Replace the toner cartridge on the developer unit.
b. The carrier has been depleted from the developer by printing with a low toner
condition. Replace the developer unit with a new one that has been charged recently
with new carrier.
c. The OPC drum has been damaged by carrier on its surface and must be replaced.
222.
There is something on the transfer corona wire or in the corona wire channel.
a. Clean any toner from the corona wire with the corona cleaning felt.
b. Remove any paper in the corona wire channel.
230.
Black line (indistinct width with fuzzy edges).
This line will still be present when the printer is operated with the laser beam blocked at
the LSU cover glass.
231.
The OPC drum is not being charged correctly.
