Sensor Tests
The technician should test the functionality of each sensor by blocking the
sensor and watching its state change on the front panel.
NOTE Several jam sensors only change state if a jam has occurred. All doors (interlock
switches) must remain closed or defeated to test for a changed state.
NOTE The default state of all sensors are shown under the following conditions:.
The printer's front panel displays "Ready to Print."
All covers are closed.
All routine maintenance items and toner cartridges are installed.
All trays and Tray 1 (MPT) have paper in them.
No paper is in the paper path or Finisher.
The Finisher is docked correctly to the printer.
No motor tests have been performed to change the position of any components.
The waste cartridge is not full.
