Topic
In a very rare case, static electricity on the TABLE PAPER was short-circuited to the side plate attached the PF
main PWB after paper feeding which cause damage to the motor driver IC on the PF main PWB (303KF01020)(*).
Therefore, the discharger brushes (DISCHARGER TP: No1) were added to the rear side of the TABLE PAPER to
secure the antistatic function.
* If the motor driver IC is damaged, the TABLE PAPER cannot be lifted up, which causes no paper feed jam.
1. Two pcs. of the DISCHARGER TP (No.1) were added to the TABLE PAPER.
