• Description
Print density is uneven between left and right.
Check and Cause
Solution
1. The pressure force on the left and right
springs of the transfer roller is not even,
the springs are damaged, the transfer
roller is improperly installed, or the trans-
fer roller bushing or holder is damaged.
2. The toner level is not even on the devel-
oper roller due to the bad blade.
1. Replace both the left and right Spring
Holder.
2. Occur in the developer cartridge, replace
the developer and try to print out.

Check and Cause
Solution
1. Recycled recording paper has been
used.
2. The life of the Developer has expired.
(The weight at the expiration of the
developer's life: 800 ± 20g)
3. The up-to-down movement of the trans-
fer roller is swift?
4. The HVPS is normal?
(Perform DCU diagnostic code 01~04)
1. B/S is not guaranteed when using recycled
paper.
2. Replace the Developer that has expired.
3. Clean the busing part of the transfer roller.
4. Replace the Developer if not solved by the
above direction 1~3.
