Printers and Multifunctional devices

Question 1

How is print resolution measured?

Answer 1

Dots per inch (dpi)

Question 2

How is print speed measured?

Answer 2

Pages per minute (ppm)

Question 3

What is the black toner used in laser printing made of?

Answer 3

carbon melt mixed with a polyester resin, while color toner trades carbon for other pigments.

Question 4

What is Hard Drive Caching?

Answer 4

Modern devices contain a hard drive or other storage media to cache copies of what the device prints, scans, copies, or faxes.

Question 5

What does the pickup roller do?

Answer 5

Grabs the paper.

Question 6

What does the separation pad do?

Answer 6

Uses friction to separate a single sheet from any others that were grabbed.

Question 7

What does the Fuser Assembly do?

what’s the function of the Pressure Roller and the Heated Roller?

Answer 7

It’s the final step of printing. It fuses the toner to the paper.

Pressure Roller- presses against the bottom of the page.

Heated Roller- Presses down on the page, melting the toner onto the paper.

Question 8

What does the toner cartridge do?

Answer 8

Supplies the toner that creates the image on the page

Question 9

What is the Imaging Drum?

Answer 9

An aluminum cylinder coated with particles of photosensitive compounds.

When light hits these particles, whatever electrical charge they may have “drains” out through the grounded cylinder.

Question 10

What is the Erase Lamp?

Answer 10

The erase lamp exposes the entire surface of the photosensitive drum to light, making the photosensitive coating conductive.

Any electrical charge present in the particles bleeds away into the grounded drum, leaving the surface particles electrically neutral.

Question 11

What is the Primary Corona/Charge Roller?

Answer 11

Enables voltage to pass to the drum and charge the photosensitive particles on its surface

When the primary corona or primary charge roller is charged with an extremely high voltage, an electric field (or corona) forms, enabling voltage to pass to the drum and charge the photosensitive particles on its surface

Question 12

What is the Laser?

Answer 12

Writing mechanism of the printer. Writes an image onto the Drum.

Question 13

What is the Toner?

Answer 13

A fine powder made up of plastic particles bonded to pigment particles

Question 14

What is the Transfer Corona/Transfer Roller

Answer 14

Gives the paper a positive charge that draws the toner onto the paper

Question 15

Which type of printer takes advantage of tractor feed during printing process?

Answer 15

Impact

Question 16

What is RET, and what does it do?

Answer 16

Resolution Enhancement Technology.

RET enables the printer to insert smaller dots among the characters, smoothing out
the jagged curves that are typical of printers that do not use RET

Uses a portion of the printer’s RAM

Question 17

What mechanism is used by most inkjet printers to push ink onto the paper?

Answer 17

Electroconductive plates

Question 18

On a dot-matrix printer, what physically strikes the ribbon to form an image?

Answer 18

Printwires

Question 19

What are considered to be dot-matrix printer consumables?

Answer 19

Ribbon, Flywheel

Question 20

What part must be vacuumed or replaced periodically to prevent damage caused by the action of the corona?

Answer 20

The ozone filter

Question 21

What printing process uses heat-sensitive plastic film embedded with various color dyes?

Answer 21

Dye-sublimation

Question 22

What are the consumables of Impact Printers?

Answer 22

Paper and Ribbons

Question 23

What are considered Inkjet Consumables?

Answer 23

Paper and Ink Cartridges
