1. Multifeeder Pickup Assembly (no paper, pickup delay jam)
If copy paper does not reach the pre-registration roller paper sensor within a specific period of
time in multifeeder mode, the condition will be identified as the absence of paper; the machine will
stop the main motor in about 1.5 sec, and indicate the Add Paper message.
If the pre-registration roller paper sensor detects copy paper during this 1.5 sec period (ap-
proximate), the machine will identify the condition as a pickup delay jam, and flash the Jam indica-
tor.
