The causes and solutions of Bad images

Light dark background appears across entire printed page.
Check 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? (see the
configuration sheet)
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 20,000 pages with
5% coverage. If it prints more than
23,000 pages with 2% coverage, a
background can occur.
2. The image quality 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.
