Paper Feed Problem, E Feeder/
100-Sheet Auxiliary Feeder
Check for the following: paper or envelope jammed in the feed path;
missing hold-down weight; adjustable guide out of position; feeder
cable loose, disconnected, or plugged in the wrong connector;
feeder incorrectly installed; worn or damaged rollers or gears;
warped or damaged envelopes being used; envelopes being
improperly installed (envelope flaps must rest against the paper
edge guide); envelopes other than 20- or 24-pound being used in
the e feeder; paper other than 20- or 24-pound being used
in the 100-sheet auxiliary feeder; envelopes being interleaved with
paper.
Run the diagnostics Envelope Feed test and make sure the feed
magnet is being energized. If not, check the resistance of the
magnet at (10P/10R/12R/12L/12C) J12-1 to J12-2 (16L)J9-1 to J9-2
on the feeder cable; the resistance should be from 105 Ohms to 155
Ohms. If the magnet is good, reconnect the cable and monitor the
voltage between the two pins of the connector while running the
Envelope Feed test; if the voltage does not increase momentarily as
the magnet is picked, replace the system board.
Check the adjustment of the feeder magnet. If paper is being bent or
double-fed, check the adjustment of the feeder restraint spring.
Printhead
Note: The printhead is a sealed unit. It contains no parts that can
replaced or serviced.
Verify the continuity of the fan/mirror motor cable and the hsync
cable. Verify the presence of the following voltages: +24VDC at
(10P/10R/12R/12C/12L) J5-1 (16L) J3-1, +5VDC at (10P/10R/12R/
12C/12L) J6-5 (16L) J4-5, +5VDC at (10P/10R/12R/12C/12L), J6-1
(16L) J4-1.
If these voltages are not correct, replace the system board.
5VDC at pin 5 on the fan/mirror motor cable at the mirror
motor board. If the voltage is correct replace the printhead; if the
voltage is bad and the cable is OK replace the system board.
