Basic operation

Engine-control system

Laser scanner system

Image-formation system

Pickup, feed and delivery system

Accessory

The printer routes all high-level processes through the formatter, which stores font information, processes the print image, and communicates with the host computer.

The basic printer operation comprises the following systems:

● The engine-control system, which includes the power supply and the DC controller printed circuit assembly

(PCA)

● The laser scanner system, which forms the latent image on the photosensitive drum

● The image-formation system, which transfers a toner image onto the paper

● The pickup, feed, and delivery system, which uses a system of rollers and belts to transport the paper

through the printer

● Accessory (optional paper feeder)

Sequence of operation

The DC controller PCA controls the operating sequence, as described in the following table.

Table 1-1 Sequence of operation

Period Duration Description

Waiting From the time the power is turned on, the door is

closed, or when the printer exits Sleep mode until the printer is ready for printing.

Standby From the end of the waiting sequence, the last rotation

until the formatter receives a print command, or until the printer is turned o.

● Detects the fuser

● Heats the fuser sleeve in the fuser

● Pressurizes the pressure roller in the fuser

● Detects the toner cartridges

● Alienates all of the developing rollers from the

photosensitive drums in the toner cartridges

● Alienates all of the transfer rollers from the

photosensitive drums in the toner cartridges

● Rotates and stops each motor

● Rotates and stops each fan

● Detects the ITB

● Cleans the ITB and secondary transfer roller

● Is in the Ready state

● Enters Sleep mode if the formatter sends the

sleep command

● Rotates and stops each fan

● Calibrates if the formatter sends the calibration

command

Initial rotation From the time the formatter receives a print command

until the paper enters the paper path.

● Rotates each motor

● Rotates each fan

● Activates the high-voltage power supply

● Prepares the laser scanner unit

● Warms the fuser to the correct temperature

ENWW Basic operation 5

Table 1-1 Sequence of operation (continued)

Period Duration Description

Printing From the time the rst sheet of paper enters the paper

path until the last sheet has passed through the fuser.

Last rotation From the time the last sheet of paper exits the fuser

until the motors stop rotating.

● Forms the image on the photosensitive drums

● Transfers the toner to the paper

● Fuses the toner image onto the paper

● Moves the last printed sheet into the output bin

● Stops each motor

● Stops each fan

● Stops the high-voltage power supply

● Stops the laser scanner unit

● Turns the fuser heater o

● If another print command is received, the printer

enters the initial rotation period when the last rotation is complete.
