Paper Size Sensor (PL 9.3.36)
Note
If the optional Tray 3 Feeder is installed, it must be removed before
perfoming this procedure.
1.
Remove the left cover from the printer (page 8-8).
2.
If Tray 2 has not already been removed, remove it now.
3.
Disconnect CN 1 (to the Print Cartridge Interconnect Board) from the Paper Size
Sensor.
4. Gently turn the printer upside down.
Note
The Paper Size Sensor can be removed and replaced without removing the
rear crossbar. However, to provide improved access, remove the crossbar
screw above the Paper Size Sensor and loosen the screw on the other side so
you can swing the crossbar out of the way.
5.
On the left side of the printer, remove 2 screws, one on either side of the rear
crossbar, that secure the Paper Size Sensor to the printer chassis.
6.
Pull up on the sensor assembly until it is clear of the mounting pins and then
remove it from the printer.

1.
Remove the Print Cartridge (page 8-4) and protect it from light.

Remove the Top Cover Assembly (page 8-9).
