paper from being taken up and fed in with the first one.

Paper empty detection

• There are the Multipurpose Tray Paper Empty Sensor (PE1) and the Multiple Bypass
Tray Paper Empty Sensor (PE2) provided on the upper part of Tray 1. They function to
detect paper loaded in Tray 1 and the Multiple Bypass Tray, respectively.
• When there is a paper stack loaded in the tray, the actuator is raised to block the Paper
Empty Sensor.
• When paper runs out, the actuator drops into the hole in the tray, unblocking the Paper
Empty Sensor.

Paper take-up retry function

• To reduce the number of paper misfeeds as a result of a paper take-up failure, a paper
take-up retry sequence is carried if the Paper Take-Up Switch is not actuated and deac-
tuated within a predetermined period of time.
• This function is provided for paper take-up from any printer paper tray.
