CompTia A+: Chapter 4

Question 1

Which voltage is applied to the paper to transfer the toner to the paper in an EP process laser printer?

Answer 1

+600VDC [Because the toner on the drum has a slight negative charge, it requires a positive charge to transfer it to the paper.]

Question 2

Which types of printers are referred to as page printers because they receive their print job instructions one page at a time? (Choose Two)

Answer 2

Inkjet printer and Laser printer

Question 3

Which of the following is not an advantage of Universal Serial Bus (USB) printer interface?

Answer 3

Allowing the printer to communicate with networks, servers, and workstations. [ The rate of transfer and ability to recognize new devices are two major advantages of the USB interface.]

Question 4

You have a finance manager who needs to print more contracts in triplicate. Which type of printers are best for printing on multipart forms?

Answer 4

Dot-Matrix [ Dot- Matrix printers are impact printers which makes them the best for printing multipart forms. Daisy wheel printers can be used with multipart forms as well.]

Question 5

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?

Answer 5

Exposing

Question 6

Which of the following is fed through an extruder on a 3D printer to create objects?

Answer 6

Filament

Question 7

Recently, employees have been printing off unauthorized materials that may contain hate speech. Which of the following can be used to see which users printed specific jobs?

Answer 7

Audit Logs [ Audit logs will track print jobs and the users that 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]

Question 8

Which device in an ink jet printer contains the print head?

Answer 8

Ink Cartridge [ 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.]

Question 9

What is the correct order of the steps in the EP imaging process?

Answer 9

Processing, charging, exposing, developing, transferring, fusing, and cleaning.

Question 10

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)

Answer 10

User authentication (username, password), and badging [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]

Question 11

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

Answer 11

Toner, print drum, and cleaning blade [The laser is usually contained within the printer, not the toner cartridge.]

Question 12

What happens during the developing stage of laser printing?

Answer 12

After a laser has created the 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 fuse 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.

Question 13

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

Answer 13

Parallel, USB, network [ Printers can communicate via parallel, serial, USB, network, and wireless. SATA is a bus interface that connects host bus adapters to storage devices such as hard drives and optical drives.]

Question 14

You have just installed a new printer, but it prints only garbled text? Which of the following is likely the problem?

Answer 14

Outdated drivers [ The solution is to ensure that the most recent printer drivers have been downloaded and installed from the manufacturers website.]

Question 15

Which printer contains a wheel that looks like a flower with raised letters and symbols on each “petal”?

Answer 15

Daisy Wheel

Question 16

What part of a laser printer supplies the voltages for charging and transferring corona assemblies?

Answer 16

HVPS (High voltage power supply)

Question 17

Which printer part gets the toner from the photosensitive drum onto the paper?

Answer 17

The transfer corona assembly [ The printer controller circuitry converts signals from the PC into signals from the various printer assemblies. The paper transport assembly controls the movement of the paper through the printer.]

Question 18

Which step in the laser printing process occurs immediately after the exposing phase?

Answer 18

Developing [Processing -> Charging -> Exposing -> Developing -> Transferring -> Fusing -> Cleaning]

Question 19

Which laser printer component permanently presses the toner onto the paper?

Answer 19

The Fuser Assembly []

Question 20

Which of the following most accurately describes how to obtain a firmware upgrade for your laser printer?

Answer 20

Download from manufacturers website [ Firmware upgrades are typically free from the manufacturer’s website. A technician does not need to install a new chip, because firmware is upgraded via software. It’s unlikely that the manufacturer will send you the upgrade on a DVD; it will refer you to it’s website to download it.]

Question 21

Performance Based Question Your network has several inkjet printers in use. A user is complaining that their documents are consistently printing with extra smudges along the lines of print on one of them. What steps would you take to clean the printer?

Answer 21

1.) Power on the printer and open the top cover to expose the area that contains the print cartridges.
2.) Initiate a self cleaning cycle.
3.) When the print head moves from it’s resting place, pull the AC power plug.
4.) Locate the sponge pads on which to apply the cleaning solution.
5.) Using the supplied syringe, apply the cleaning solution to the sponge pads until they are saturated.
