Chapter 5 Flashcards
Which voltage is applied to the paper to transfer the toner to the paper in an EP process laser printer?
+600VDC
–600VDC
+6000VDC
–6000VDC
A. Because the toner on the drum has a slight negative charge (–100VDC), it requires a positive charge to transfer it to the paper; +600VDC is the voltage used in an EP process laser printer.
Which types of printers are referred to as page printers because they receive their print job instructions one page at a time? (Choose two.)
Daisy-wheel Dot-matrix Inkjet Laser Thermal
C, D. A page printer is a type of computer printer that prints a page at a time. Common types of page printers are the laser printer and the inkjet printer.
Which of the following is not an advantage of a Universal Serial Bus (USB) printer interface?
It has a higher transfer rate than a serial connection.
It has a higher transfer rate than a parallel connection.
It automatically recognizes new devices.
It allows the printer to communicate with networks, servers, and workstations.
D. The rate of transfer and the ability to recognize new devices automatically are two of the major advantages that currently make USB the most popular type of printer interface. However, it is the network printer interface that allows the printer to communicate with networks, servers, and workstations.
Which type of printers can be used with multipart forms?
Inkjet printers
Laser printers
Thermal printers
Dot-matrix printers
D. Dot-matrix printers are impact printers and therefore can be used with multipart forms. Daisy-wheel printers can be used with multipart forms as well.
Which step in the EP imaging process uses a laser to discharge selected areas of the photosensitive drum, thus forming an image on the drum?
Exposing
Transferring
Developing
Cleaning
A. The exposing step uses a laser to discharge selected areas of the photosensitive drum, thus forming an image on the drum.
Which of the following is fed through an extruder on a 3D printer to create objects?
Plastic
Metal
Filament
Extrusion powder
C. 3D printers use filament to create objects. Filament is often plastic, but it can contain metals too. There is no extrusion powder.
What voltage does the corona wire or corona roller hold?
+600VDC
–600VDC
0VDC
–100VDC
A. For the toner (which has a charge of –600VDC) to be transferred from the print drum (which has a charge of –600VDC) to the paper, there must be a positive, or opposite, charge of greater difference to break the –600VDC charge from the drum.
Which device in an inkjet printer contains the print head?
Toner cartridge
Ink cartridge
Daisy wheel
Paper tray
B. In an inkjet printer, the ink cartridge is the actual print head. This is where the ink is expelled to form letters or graphics. Toner cartridges are used by laser printers to store toner. A daisy wheel is the device that impacts the letters on the paper in a daisy-wheel printer. Paper trays are the storage bins in laser printers and inkjet printers that allow the pickup rollers to feed the paper into the printer.
What is the correct order of the steps in the EP imaging process?
Developing, exposing, transferring, fusing, charging, cleaning, processing
Charging, processing, exposing, developing, transferring, fusing, cleaning
Processing, transferring, exposing, developing, charging, cleaning, fusing
Processing, charging, exposing, developing, transferring, fusing, cleaning
D. The correct sequence in the EP imaging process is processing, charging, exposing, developing, transferring, fusing, and cleaning.
Most printers that use the electrophotographic process contain how many standard assemblies?
Five
Six
Four
Nine
D. There are nine standard assemblies in an electrophotographic process printer. Early laser printers using the electrographic process contained the nine standard assemblies. Newer laser printers do not require an ozone filter and contain only eight standard assemblies.
What is typically included in the EP laser printer toner cartridge? (Choose three.)
Toner
Print drum
Laser
Cleaning blade
A, B, D. An electrophotographic (EP) laser printer toner cartridge includes the toner, print drum, and cleaning blade. The laser is usually contained within the printer, not within the toner cartridge.
What happens during the developing stage of laser printing?
An electrostatic charge is applied to the drum to attract toner particles.
Heat is applied to the paper to melt the toner.
The laser creates an image of the page on the drum.
An electrostatic charge is applied to the paper to attract toner particles.
A. After a laser has created an image of the page, the developing roller uses a magnet and electrostatic charges to attract toner to itself and then transfers the toner to the areas on the drum that have been exposed to the laser. The toner is melted during the fusing stage. The laser creates an image of the page on the drum in the exposing stage. An electrostatic charge is applied to the paper to attract toner in the transferring stage, which happens immediately after the developing stage.
Which of the following are possible interfaces for printers? (Choose three.)
Parallel
SATA
USB
Network
A, C, D. Printers can communicate via parallel, serial, USB, wireless, and network connections.
You have just installed a new printer, but it prints only garbled text. Which of the following is likely the problem?
Wrong IP address
Worn print head
Incorrect printer drivers
Unsupported printer
C. If a printer is using out-of-date or incorrect printer drivers, the printer may produce pages of garbled text. The solution is to ensure that the most recent printer drivers are downloaded from the manufacturer’s website.
Which printer contains a wheel that looks like a flower with raised letters and symbols on each “petal”?
Inkjet printer
Daisy-wheel printer
Dot-matrix printer
Laser printer
B. The daisy-wheel printer gets its name because it contains a wheel with raised letters and symbols on each “petal.”
