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.
