Print Quality - Banding
Service Tip: Banding is difficult to detect except on a page
with a uniform gray or a large amount of graphics printed on the
page. Banding is primarily due to a variation in the speed of the
paper as it feeds through the printer, especially in the
development and transfer process. Inspect theall other paper

wide, narrow, light or dark.
Action
e If the problem is just on one side of the page, check the
charge roll linkage spring on that side. You can check to see if
enough force is being applied to the charge roll by applying a
slight downward pressure with your finger to the charge roll link
arm that the spring is attached to while you run a print test
sample. See if the problem changes or goes away. If this fixes or
changes the problem, then check the springs and charge roll link
arm assemblies for binds or defective parts. Replace as
necessary.
bly rm
Check the charge roll for any signs of toner buildup or other
contamination on the outer edges that correspond to the bands on
the page. Check the charge links and arms for proper operation,
binds or incorrectly mounted counterbalance springs. Repair or
replace as necessary.

If the voltage does not vary, check the continuity of line J9-7
in the front cable harness. If there is no continuity, replace the
cable harness. If there is continuity, replace the HVPS. If this
does not correct the problem, replace the engine board.
Turn the printer Off and check the resistance between J9-9 and
printer ground. The resistance measures approximately 0 ohms. If
incorrect, make sure the engine board is mounted correctly and
securely grounded. If correct, replace the engine board.

assembly cable to the transformer on the HVPS board. Check the
continuity of the cable from the bearing to the spade terminal on
the cable. If incorrect, replace the right side transfer arm
assembly. If correct, replace the HVPS.
