Pickup Retry - Canon iR1600 Service Manual

CHAPTER 6 PICKUP/FEDING SYSTEM

2.1.3 Pickup Retry

If paper is not picked up despite the rotation of the pickup roller, the machine will execute
a retry operation. The DC controller PCB keeps count of the time starting when the cassette
pickup solenoid (SL151) goes ON. If the retry sensor (PS152) does not detect the leading
edge of paper within a specific period of time, the machine will turn on the cassette pickup
solenoid once again for a pickup retry.
If the retry sensor does not detect the leading edge of paper within a specific period of
time after executing a retry pickup twice, the machine will identify the condition as a jam,
and will indicate a jam message on the LCD in the control panel.
