Lexmark CS720 User Manual

Isolation unit section
The paper enters the isolation unit through one of two paths, each path having its own isolation roller. If the
paper is fed from tray 1, the tray 1 isolation nip moves the paper through the isolation housing and into the
aligner roller. If the paper is fed from MPF, option tray, or duplex, the alternate isolation roller moves the paper
through the isolation housing and into the aligner roller.
The following occurs if the paper does not reach the sensor (tray 1 pick):
• If the paper is fed from the tray and does not reach the sensor, a 241.16 error is generated.
• If the paper is fed from the MPF and does not reach the sensor, a 240.06 error is generated.
• If the paper is fed from an option tray and does not reach the sensor, a 240.x3 error is generated.
• If the paper is fed from the duplex and does not reach the sensor, a 232.x3 error is generated.
