Answer 10

Applies page image to transfer belt or roller

Question 11

Laser Printer Developer

Answer 11

Pulls toner from toner supply and sends it to the imaging drum

Question 12

Laser Printer Fuser Assembly

Answer 12

Fuses the page image to the paper

Question 13

Answer 13

Transfers the page image from the drum to the page

Question 14

Laser Printer Pickup Rollers

Answer 14

Picks up Paper

Question 15

Laser Printer Paper Separation Pad

Answer 15

Enables pickup rollers to pick up only one sheet of paper at a time

Question 16

Laser Printer Duplexing assembly

Answer 16

An assembly that switches paper from the front to the back side so that the printer can print on both sides of the paper

Question 17

Laser Printer (Processing)

Answer 17

The printer’s raster image processing engine receives the page, font, text, and graphics data from the printer driver, creates a page image, and stores it in memory.

Question 18

Laser Printer (Charging)

Answer 18

The cylinder-shaped imaging drum receives an electrostatic charge of –600Vdc (DC voltage) from a conditioning roller.

Question 19

Laser Printer (Exposing)

Answer 19

A moving mirror moves the laser beam across the surface of the drum. As it moves, the laser beam temporarily records the image of the page to be printed on the surface of the drum by reducing the voltage of the charge applied by the charger corona to –100Vdc.

Question 20

Laser Printer (Developing)

Answer 20

The drum has toner applied to it from the developer; because the toner is electrostatic and is also at –600Vdc, the toner stays on only the portions of the drum that have been reduced in voltage to create the image.

Question 21

Laser Printer (Transferring)

Answer 21

While the sheet is being fed into the printer, it receives an electrostatic charge of +600Vdc from a corona wire or roller; this enables it to attract toner from the drum.

Question 22

Laser Printer (Fusing)

Answer 22

The printed sheet of paper is pulled through fuser rollers, using high temperatures to heat the toner and press it into the paper.

Question 23

Laser Printer (Cleaning)

Answer 23

To prepare the drum for a new page, the image of the preceding page placed on the drum by the laser or LED array is removed by a discharge lamp. Toner that is not adhering to the surface of the drum is scraped from the drum’s surface for reuse.

Question 24

Laser Printer

Answer 24

A page printer that stores the entire contents of the page to be printed in its memory before printing it.

Question 25

Inkjet Printer

Answer 25

Spray controlled dots of ink onto the paper to form characters and graphics from a tightly spaced group of nozzles.

Question 26

Thermal Printer

Answer 26

Uses heat transfer to create text and graphics on the paper.

Question 27

Impact Printer

Answer 27

Uses a mechanical print head that presses against an inked ribbon to print characters and graphics.
