4.2.8 BACKGROUND
Description:
Light dark background appears across entire printed page.
Symptom and Cause Solution
1. Is the text less than 2% coverage per a
page, and has the machine been out of
operation for a long time?
2. Is a recycled print cartridge being
used?
3. Has the life span of the print cartridge
expired?
4. Is the movement (Up and Down) of the
transfer roller smooth?
5. Is the HVPS normal?
1. The print cartridge is basically
designed to print 7,000 pages with 5%
coverage. If it prints more than 8,000
pages with 2% coverage, a
background can occur.
2. The A/S is not guaranteed if using a
recycled print cartridge.
3. Replace the print cartridge when the
life span of it has expired.
4. Clean the bushing part of the transfer
roller.
5. If the problem is still not solved,
replace the print cartridge.
