Laser printers share much of the same technologies as photocopiers. Rollers pull a sheet of paper from a paper tray and through
a charge roller
, which gives the paper an electrostatic charge. At the same time, a printing drum is given the opposite charge.
What kind of printer creates an image on paper by physically striking an ink ribbon against the paper’s surface?
Dot matrix printers
typically use a print head that moves back and forth or in an up-and-down motion on the page and prints by impact, striking an ink-soaked cloth ribbon against the paper, much like the print mechanism on a typewriter or line printer.
What needs to be vacuumed or replaced periodically in a laser printer?
B.
The ozone filter
should be periodically vacuumed or changed.
What should a user do if their dot matrix printer output is covered with dots and small smudges on back of the paper?
What should you do if your dot-matrix printer output is covered with dots and small smudges?
Clean the platen
.
Which component of the laser printer applies the positive charge to the paper?
The secondary corona wire, or transfer roller
, applies a positive charge onto the paper. The agitator unit inside the toner cartridge hopper spins, and the toner begins to heat up.
Which one is the disadvantage of a laser printer?
Although laser printers work well with many types of regular paper, they
work poorly with special papers
. Between the sometimes complicated path that paper travels inside of them and their high temperature fuser rollers, you can’t print just anything with a laser printer.
What is another name for a laser printer?
printer ball printer | character printer color printer | daisy-wheel printer dot-matrix printer | graphics printer ink-jet printer | LCD printer LED printer |

Which printer Cannot print graphics?
Daisy-wheel printers
are loud and slow. They cannot print graphics, and cannot change fonts unless the print wheel is physically replaced. With the advent of laser printers, daisy-wheel printers are generally not used in modern computing environments.
Which of the following printers is using a ribbon?
The typewriter and dot matrix printers
are the equipments that utilize ribbon cartridges the most. The dot matrix printers print images by striking tiny dots coming into contact with a cloth strip soaked in printer ink. Thermal printers used in cash machines, faxes, and similar devices use printer ribbons.
Which is the fastest printer?
Laser printer
is known to be the fastest printer.
Which printer uses a print head of small pins?
A dot matrix printer
is an impact printer that prints using a fixed number of pins or wires. Typically the pins or wires are arranged in one or several vertical columns. The pins strike an ink-coated ribbon and force contact between the ribbon and the paper, so that each pin makes a small dot on the paper.
What type of printer is most suitable for multipart forms?
When printing multipart forms, you need to use
an impact printer
to speed up the printing process as well as to ensure that each form within the multipart packet is imprinted properly. Impact printers are also known as dot matrix printers and are compatible with a variety of PC and Mac systems.
Which of the following tools would be the most appropriate to clean the inside of a laser printer?
A toner vacuum
would be an appropriate tool to clean the inside of a laser printer.
What is the drum in a laser printer?
What is the drum unit? The drum unit
transfers the toner to the paper
. The laser printer puts the toner on the roller called “The photosensitive drum” inside the drum unit, and then prints letters and images by fixing toner to the paper by heat and pressure.
Why is it called laser printer?
The laser printer was the first to be invented and was done so in 1969 by Gary Starkweather while working in the Xerox product development team.
His idea was to use lasers to imprint an image onto a copier drum which would then be transferred onto paper
. Hence, the name ‘Laser printer’.
Can a laser printer drum be cleaned?
You can use a
clean, lint-free cloth
instead, but a toner cloth is ideal. Wipe down the exterior of the drum to remove loose toner.
