Operational Theory

Interlock Mechanism

When the front cover assembly, fuser cover or cartridge cover is open, a CLOSE DOOR message displays indicating the interlock system is open.

If the front door assembly or the fuser cover are closed, the door switch actuator 3 [A] moves in the direction of arrow [B].

When the cartridge door is closed the door switch actuator 1 [C] rotates in the direction shown by arrow [D] and activates the door switch [E] and laser switch [F].

If either of these doors are not closed, actuator 1 [C] will not rotate and the switches will not turn on.

When door switch [E] is not activated, it prevents the LVPS from supplying power to the printer.

When the laser switch [F] is not activated, the engine board will not turn the printhead on.
