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.
