Paper Size Sensor
Note: If the optional Tray 3 Feeder is installed, it must be removed before perfoming this
procedure.
1. Remove:
■ Print Cartridge
■ Tray 2 and Tray 3 (if installed)
■ Left Cover on page 4-5
2. Disconnect CN 1 from the Paper Size Sensor.
3. 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.
4. 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.
5. Pull up on the sensor assembly until it is clear of the mounting pins and then remove it
from the printer.
