Audit logs.
Audit logs will track print jobs and the users who printed them. User authentication is where a user is required to log into the printer. This can be done via badging—or swiping an employee badge on a badge reader on the printer—or by manually entering credentials. Secured prints is when a print job is held until a user authenticates at the printer and tells it to start printing.

36
Q

Which device in an inkjet printer contains the print head?

Toner cartridge, Ink cartridge, Daisy wheel, Paper tray

A

Ink cartridge.
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.

37

38
Q

The network administrator has set up security on office MFDs that requires users to authenticate before printing. Which of the following are valid methods for users to authenticate to the MFD? (Choose two.)

A) Use an authentication log.
B) Enable secured print.
C) Type their username and password on the MFD’s touchscreen.
D) Use SMB.
E) Use their company ID for badging.

A

C, E.
Two ways for users to authenticate are to use user authentication (which requires typing in the username and password) or badging, which requires the MFD to have a badge‐scanning feature. Secured print will save print jobs until they are ready to be released. SMB is a file‐ and print‐sharing protocol used by MFDs to send scanned documents to a shared network folder. There are no printer authentication logs, but audit logs may be used to see who has used the MFD.

39
Q

What is typically included in the EP laser printer toner cartridge? (Choose three.)

Toner, Print drum, Laser, Cleaning blade

A

Toner, Print drum, 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.

40
Q

What happens during the developing stage of laser printing?

A) An electrostatic charge is applied to the drum to attract toner particles.
B) Heat is applied to the paper to melt the toner.
C) The laser creates an image of the page on the drum.
D) An electrostatic charge is applied to the paper to attract toner particles.

A

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.

41
Q

Which of the following are possible interfaces for printers? (Choose three.)

Parallel, SATA, USB, Network
