● Post-secondary Transfer Static Eliminator Bias Control
Improve separation performance of thin paper (52-105 g paper).
Apply the post-secondary transfer static eliminator bias (DC negative) generated at the
secondary transfer static eliminator PCB (PCB29) to the post-secondary transfer static
eliminator.
Apply a bias to thin paper (52-105 g paper).

● Pre-primary Transfer Charging Wire Cleaning Control
Prevent an image failure caused by dirt on the pre-primary transfer charging wire.
Timing of Execution
Simultaneously executed with primary charging wire cleaning control.
Description
The wire cleaner moves back and forth and clean the pre-primary transfer charging wire,
which is driven by the pre-primary transfer charging wire cleaning motor (M5).
There is no mechanism to detect the position of the wire cleaner.
Related Service Mode
• Execute the wire cleaning.
