Back 11

Fuser Assembly (Fuser)

Front 12

Exposes and processes all of the data received from the computer and coordinates the steps needed to produce the finished page

Back 12

Formatter Board

Front 13

There are ____ steps in the laser print process

Back 13

Front 14

The EP drum is cleaned with a rubber squeegee blade

Back 14

Cleaning

Front 15

Charges are removed from the EP drum in prep for the next image

Back 15

Erasing

Front 16

The imaging drum is prepped by charging it with a charge roller. The roller is connected to a high-voltage power supply unit to produce negative charges. A laser with positive charges is cast on the negatively charged drum. A mirror that rotates reflects the laser onto the drum.

Back 16

Cleaning (conditioning)

Front 17

A laser writes to the EP drum, giving portions of the drum a weaker negative charge

Back 17

Writing

Front 18

Toner is attracted to the drum that were hit by the laser. Inside the toner cartridge, a thin layer of toner is applied to the surface of the drum. A wipe blade spreads the toner evenly, leaving only the toner writing by the laser

Back 18

Developing

Front 19

Positively charged paper is fed into the printer by the pickup rollers. The positively charge paper attracts the negatively charged toner that is stuck to the drum. The toner sticks loosely on the paper.

Back 19

Transferring

Front 20

The toner is melted and fused with the paper permanently.

Back 20

Fusing

Front 21

This printer forms images by spraying liquid ink from an ink cartridge out of nozzles.

Front 23

A motor and belt mechanism moves a printhead across the printer. A stepper motor, along with gears, advance the paper into the printer

Back 23

Preparation

Front 24

As the printhead moves across the paper, images are formed by heat or vibration forcing liquid ink out of nozzles onto the paper.

Back 24

Ink Dispersion

Front 25

The printhead moves back and forth across the paper, printing one row of the image at a time.

Back 25

Ink Deposit

Front 26

The paper advances using rollers and feeders after every row until the page is covered

Back 26

Paper Advance

Front 27

The process that enables automatic printing and scanning on both sides of printing media.

Back 27

Duplexing (Duplexing Assembly)

Front 28

A printer that uses a heating element to create the image on the paper with dye, ink from ribbons, or directly with pins while the feed assembly moves the media through the printer.

Back 28

Thermal Printer

Front 29

A thermal printer is most commonly used with

Back 29

Cash registers to print receipts

Front 30

Used to print receipts or invoices

Back 30

Impact Printer

Front 31

A type of impact printer that uses a set of pins to strike the ribbon. Dot-matrix printers create printed characters by using various combinations of dots.

Back 31

Dot-matrix printer

Front 32

The impact printer process consists of ___ steps

Back 32

4

Front 33

Pins shoot out of the printhead and strike an ink-coated ribbon. The dots created on the page become the printed text/graphic.

Back 33

Pin Strike

Front 34

The pin transfers ink from the ribbon to the printed page.

Back 34

Ink transfer

Front 35

After pins have fired, an electromagnet pulls them back in. The pins move a fraction of an inch and another set of pins is fired.

Back 35

Printhead Move

Front 36

This connects the dots to form sharper and clearer letters.

Back 36
