High-Capacity Feeder Input Tray Service Check

Note: Voltage measurements in the high capacity feeder input tray
service checks must be made with the high-capacity feeder attached
to the base printer to obtain accurate results.
Service Tip: Be sure the paper size switch is set to the correct paper
size setting and the rear paper guides are in the correct locations for
the size of paper installed in the high-capacity feeder tray.
Service Tip: Check the other paper sources to be sure they are
operating correctly.
The base printer indicates a dead machine condition when the
high capacity input tray is installed.

If the base printer works normally
using the AC line cord from the AC
wall outlet and does not work when
using the AC jumper from the HCIT,
check the AC jumper cord. If
defective, replace the cord. If not
defective, check the AC input and
output receptacles and wiring
harness in the HCIT. Repair or
replace the receptacles or AC wiring
harness as required.
NOTE: Make sure the ground wire is
installed correctly from the AC wiring
harness to the frame of the HCIT
and the nut and lock washer are
tightened.
