Chapter 4: Printers and Multifunction Devices Flashcards
Impact printers use a paper feed mechanism called a/an ____ that requires continuous-feed paper with holes running down both edges.
tractor feed
There are two major types of impact printers:
- Daisy-wheel
- Dot-matrix
Both ____ printers and ____ printers can use multipart forms.
daisy-wheel, dot-matrix
When the ____ printer is done printing, the print head moves back to its maintenance station, which contains a suction pump and ink-absorption pad.
inkjet
The inkjet’s ____ allows for printing on both sides of a page, and is the most likely area to incur a paper jam.
duplexing assembly
The EP (electrophotographic) laser printer toner cartridge contains the EP ____ that is coated with a photosensitive material that can hold a static charge when not exposed to light.
print drum
The laser printer’s ____ provides the high voltages used during the EP process by converting the 120V and 60 Hz AC current into higher voltages used to energize both the charging corona and the transfer corona.
HVPS or High-Voltage Power Supply
The laser printer’s ____ converts house current into three voltages: +5V and -5V for the logic circuitry and +24V for the paper transport motors. This component also runs the fan that cools the internal components of the printer.
DCPS or DC Power Supply
The laser printer’s ____, is a D-shaped roller that rotates against the paper and pushes one sheet into the printer.
feed roller
The laser printer’s ____ work together to synchronize the paper movement with the image-formation process in the EP cartridge. Both of these rollers are operated by an electronic stepper motor.
registration rollers
A laser printer’s ____ is given a high-voltage charge, which is transferred to the paper, which, in turn, pulls the toner from the photosensitive drum.
transfer corona assembly
The laser printer’s toner has a ____ static charge.
negative
A laser printer’s ____ uses two rollers that apply pressure and heat to fuse the plastic toner particles to the paper.
fuser
What are the seven major steps in order in the electrophotographic (EP) imaging process?
- Processing
- Charging
- Exposing
- Developing
- Transferring
- Fusing
- Cleaning

The two major components of interface software for printers are the ____ and the ____ software. If you use the wrong type for either, the printer will print garbage or possibly not at all.
