fuser

Which component in a laser printer is most subject to mechanical wear due to heat and pressure, and requires regular cleaning or replacement?

fuser assembly

What is the main advantage of performing low-resolution printing?

high speed printing

Which environmental factor can cause multiple sheet feeding and paper jam problems in printers?

humidity

Which tab in the Printer Properties dialog box in Windows is used to set the amount of printer memory to be used by a laser printer?

the Device Settings tab

Which laser printer component should be cleaned if the printed paper has streaks on it?

the transfer corona wire

Which printer uses special paper and ink that degenerates over time?

thermal printer

Which type of printer prints a document by selectively heating a coated paper?

thermal printer

daisy-wheel, dot matrix, and line

three types of impact printers

Which type of floor is an ideal environment to operate a laser printer?

tiled floor

Which powdery substance is used to print text and graphics in laser printers?

toner

Which component of a laser printer is responsible for transferring the toner to the paper from drum?

transfer roller

Friction feed and Tractor Feed

two methods of feeding paper through printer

Uses a wheel-shaped printing mechanism containing predefined character glyphs arranged like petals on a flower.

Daisy-wheel printer

Prints one character at a time using a print head made up of small pins.

Dot matrix printer

What should you ensure before calibrating your printer if the printer is not printing full colors correctly?

Ensure you are using the correct printer driver.

work by banging a print head or needle against an ink ribbon to make a mark on the paper, very similar to an old typewriter.

Impact printers

use ink-dispersion and wet ink to transfer an image onto paper.

Inkjet printers

What should you do if printed documents continue to have missing colors even after calibrating the printer?

Install a new ink or toner cartridge.

Which substance is used to clean a laser printer?

Isopropyl alcohol solution

use focused light, electrical charges, and a dry powder ink (called toner) to transfer an image using to paper. The photosensitive drum, rubber cleaning blade, toner, and developing roller are all contained within a replaceable laser printer cartridge.

Laser printers

The drum passes by a developing roller covered in toner. The toner is a negatively-charged combination of plastic and metal particles.

Laser printing Developing stage.

The paper passes through a set of rollers that apply heat and uniform pressure to the paper and toner, curing the image onto the paper.

Laser printing Fusing stage.

Pickup rollers grab a single sheet of paper from the paper tray or manual feed slot and move it into the printer.

Laser printing Transferring stage.

The primary corona wire applies a negative charge to the photosensitive drum as the surface of the drum rolls across the surface of the conditioning roller.

Laser printing charging stage.

A physical and electrical process cleans the previous image off the photosensitive drum.

Laser printing cleaning stage.

The laser projects the image on the photosensitive drum.

Laser printing exposing stage.

Prints an entire line at once, allowing faster output.

Line printer

A method in which a current is applied to a Piezo crystal at the rear of the ink reservoir.

Piezo-electric technology

What are the two page orientations that can be selected for printing a page?

Portrait and Landscape, also referred to as vertical and horizontal

Which Windows service loads files to memory for later printing?

Print Spooler

What should you do first when troubleshooting a printer for not printing text and images properly?

Print a test page.

Print preview, pdf, xps, image, print to file, and fax

Typical outputs for a virtual printer

network, short-range wireless, and shared printer

3 ways of sharing a printer

build physical objects using raw materials such as plastic, metal, plaster, or even living tissue.

3d Printer

What is the MOST likely reason for poor quality, smudged characters, and badly formed characters printed by a dot-matrix printer?

A damaged pin in a print head and a damaged printer ribbon

thermal and piezo-electric Technology

A dot-matrix printer is printing only one-half of each character. Which component is causing this problem?

print head

Which feature of a printer stores output from a computer until it can be printed?

printer buffer

Which print head in a dot-matrix printer will produce higher resolution?

24 pin

What should you do if your printer does not print full colors correctly even after installing the correct drivers and toner cartridges?

Calibrate the printer.

What maintenance must you perform on an inkjet printer that you suspect has clogged ink in the print head?

Run the cleaning cycle on the printer.

How can you ensure that a user can print to the same printer from any application?

Set the printer as the default printer.
