Theory of operation Theory of operation POR sequence As the printer is turned 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 338: Print Cycle
Theory of operation Print cycle Flowchart Charge Charge roller Photoconductor The charge roller applies a uniform negative electrical charge to the surface of the photoconductor. The insulative properties of the photoconductor allow it to hold a charge and its photoconductive properties allow it to discharge when exposed to light. Expose Photoconductor...
Page 339: Develop
Theory of operation Printhead The printhead emits a laser that exposes the surface of the photoconductor. The laser pulses coincide with the digital latent image. The exposed areas of the photoconductor surface are discharged, resulting in a photoconductor surface potential that is less negative than the non-exposed areas.
Page 340: Clean
Theory of operation Clean Waste toner compartment Cleaning blade Photoconductor The cleaning blade removes the residual toner from the photoconductor after the transfer. Waste toner is then stored in the waste toner compartment. After cleaning, the process moves again to the charge process and repeats each cycle until the entire image is transferred to a side of the paper.

Page 343: Duplex Print Job
Theory of operation Separator pad Transfer roller Fuser Paper exit roller The pick roller picks and the feed roller feeds the paper to the separator roller or separator pad. The feed roller feeds the paper to the transport roller. For MPF print jobs, the MPF pick roller picks and feeds the paper to the transport roller.
Page 344: Printer Paper Path Sensors
Theory of operation After the first side is printed, the paper stops at the output bin while still in the paper exit roller. The paper is fed again into the duplex paper path to have the opposite side printed. The paper travels along the duplex path until it enters again the transport roller. From there, the paper continues its path until the print job is done.
