Low Solid Area Density At Install; Intermittent Extra Print - Xerox 8825 Service Manual

Low Solid Area Density At Install

PROBLEM
At install it is difficult to attain 1.0 solid area density.
CAUSE
This symptom is a developer/toner materials package phenomena that has to do with aging.
SOLUTION
There is no fix for this problem other than to allow the material to age. After 500 to 1000 linear
feet the solid area coverage will recover.
NOTE: DO NOT USE 09 21 6 to adjust image density!!! Adjust only the image density in diag-
nostic 09 21 4.

General Procedures
Low Solid Area Density At Install, Intermittent Extra

Intermittent Extra Print

PROBLEM
Intermittently an extra print is printed. The extra print will be partially the requested print and
partially one of the internal test patterns.
CAUSE
Electrical noise that is being injected into the system is causing the system to print this strange
print. This noise is caused by either a contaminated scorotron that is arcing or the scorotron
leads breaking down. No error code is produced but the system prints a second print correctly
because it knows the first one failed.
SOLUTION
Clean the suspect scorotron and grid. Replace the grid or pins if required. Replace the
Scorotron endblock and leads by installing a scorotron end block kit (600K58730)
