Page 315: Theory Of Operation
4514-330 Theory of operation POR sequence As the printer turns on, the engine code goes through a series of tests to verify hardware integrity. If a hardware failure is detected, then it is reported to the printer. If the POR sequence cannot be completed successfully, then the printer may post an error message.
Page 316: Simplex Printing
4514-330 The MPF can be accessed by opening the MPF tray on the front door. In an MPF paper feed, the MPF paper present sensor detects the media. The instant the MPF pick roll shaft rotates, the cams on each end of the shaft disengage the MPF tray.

4514-330 Part First input roller Secondary input roller Duplex front deliver roller Duplex rear deliver roller Paper exit roller Media handling components Main drive gearbox The gearbox supplies all mechanical power requirements of the printer. Its motor, through several gears, transfers power to following paths: photoconductor drum, transfer roll, fuser, paper exit, input, duplex, and MPF.

Among other capabilities, this sensor can be used to determine the paper size sensor and the media stack height.

4514-330 Pass through sensor (option tray) Detects when the media from the option tray passes. This will trigger the pick roller to pick the next media. Capactive Toner Level Sensor (CTLS) Detects the amount of toner in the imaging unit. If the toner level is low, the cartridge auger motor is triggered to add toner from the toner cartridge to the imaging unit.

Page 322 4514-330 Step 1: Charge During the charge step, voltage is sent from the HVPS to the charge roll beside the photoconductor. The charge roll applies a uniform negative charge over the entire surface of the photoconductor to prepare it for the laser beam.
Page 323 4514-330 Step 2: Expose The laser ﬁres a focused beam of light at the surface of the photoconductor and writes an invisible image, called a latent image. The laser beam only discharges the surface where the beam hits the photoconductor. This creates a difference in charge potential between the exposed area and the rest of the photoconductor surface.
Page 324 4514-330 This process would be similar to using glue to write on a can and then rolling it over glitter. The glitter sticks to the glue but not to the rest of the can. HVPS Developer Metering Roll Blade Toner DRUM -VDC Drum Surface...
