Description

Misfeed at tray 2 feed section
12-01 The leading edge of the paper is not turned ON the tray 2 vertical transport sensor (PS12) even after the lapse of a given period of time after the tray 2 starts to feed paper.
12-40 For paper fed from the tray 2, the image write start signal permit continues to be disabled for a predetermined period of time after the timing of the image write start signal output.
- Paper jam of a sheet of paper left at the tray 2 feed section results, if the tray 2 vertical transport sensor (PS12) is turned ON when the main power switch is turned ON, a door is opened and closed, or a misfeed or malfunction is reset.
- When the main power switch is turned ON, residual paper detection starts between each sensor. Paper jam of a sheet of paper left at the tray 2 feed section results, if the tray 2 vertical transport sensor (PS12) is turned from OFF to ON.

Causes
• Paper feed motor (M22) • Tray 2 vertical transport motor (M7) • Tray 2 paper feed clutch (CL2) • Tray 2 vertical transport sensor (PS12) • Tray 2 paper feed sensor (PS13) • Paper feed/transport drive board (PFTDB) • MFP board (MFPB)
