PC Empty Sensor (PS2) Functional Check
1
Power on the printer with the PC tray (Tray 2) empty.
2 After the 05 SELF TEST and the 02 WARMING UP cycles, the PC
LOAD LETTER (or A4) or TRAY 2 EMPTY message appears.
3 Add paper to the PC tray and re-install the tray.
4 The display should read 02 WARMING UP, then 00 READY. If
the PC LOAD or TRAY 2 EMPTY message persists, replace PS2.
PS4 Check (MP Tray Empty Sensor)
1 With the printer powered ON and 00 READY displayed, select
the Config Menu from the Control Panel.
2 Configure the MP Tray (Tray 1) as a cassette (MP TRAY=CASS
or TRAY 1=CASSETTE).
3 Lock out the remaining paper trays (LOCK= PC LC or LOCK
TRAY= 2 3).
4 Remove any paper from the MP Tray (Tray 1). The printer
should display an MP LOAD [paper size] message. For the
LaserJet 5 printer, run a Self Test to generate the TRAY 1
LOAD message.
5 Insert paper into the MP Tray (Tray 1). If the MP LOAD (TRAY
1 LOAD) message persists (or if the load message never
occurred), PS4 or the sensor flag is defective.
