Adf Paper Jam Service Check - Lexmark X264dn Service Manual

ADF paper jam service check

Note: This service check should be used if the paper feeds and jams in the ADF. If the paper is not feeding into
the ADF see "ADF feed errors service check" on page
Step
1 If the ADF is multi-feeding, check for dirt on
the ADF separator pad and ADF separator
rollers. Are they dirty?
2 If the paper is skewing when it is fed into the
ADF, check the paper guide width. Is it set
correctly?
3 If paper is skewing when fed or jamming
check to see if the top cover is open or ajar.
Is the ADF top cover open or ajar?
4 Is paper failing to feed into the ADF?
5 Perform the ADF paper present, scan 1st
and scan 2nd sensor tests. See
Tests" on page
Are the sensors working properly?
6 Check the leading edge of the paper to
ensure the paper is not curled or bent in a
way that would keep it from contacting the
paper present sensor actuator. Is the paper
damaged?
7 Is there dirt in the sensors, or is the paper
present actuator stuck?
8 Are the sensor actuators on the ADF
mechanism cover damaged?
9 Is the ADF connector properly connected to
J4 on the controller board?
10 Inspect the connections on the ADF relay
card in the ADF. Are all the connections
properly connected?
11 Check the ADF cable for continuity. Is there
continuity?
12 Check for signals or voltages from J4 on the
controller board. Pin 11 and 12 should
measure +24VDC. Pin 5 should measure
+14VDC. Are there signals or voltages
present?
