ITC 190 Chapter 22

1. List the six steps used by a laser printer to print a page.

1. Cleaning. The drum is cleaned of any residual toner and electrical charge. 2. Conditioning. The drum is conditioned to contain a high electrical charge. 3. Writing. A laser beam discharges the high charge down to a lower charge, but only in places where toner should go. 4. Developing. Toner is placed onto the drum where the charge has been reduced. 5. Transferring. A strong electrical charge draws the toner off the drum onto the paper. This is the first step that takes place outside the cartridge. 6. Fusing. Heat and pressure fuse the toner to the paper.

2. Which document exhibits better quality, one printed with 600 dpi or one printed with 1200 dpi? Why?

1200 dpi. The more dots per inch there are, the more detail you can print and the finer the resolution.

11. What kind of printer is assigned an IP address?

A network printer

12. What company developed PostScript? PCL?

Adobe Systems, Hewlett-Packard

14. What tool can you use to remove loose toner from inside a printer?

An extension magnet brush

6. What should you do if an inkjet printer prints with missing dots or lines on the page?

Clean the inkjet nozzles (manually for older inkjet printers or automatically for newer ones).

9. What two Windows XP components are used to share resources on a network and access those shared resources?

Client for Microsoft Networks and File and Printer Sharing

8. What feature on a printer must be enabled so that a printer can automatically print on both sides of the paper?

Duplex printing

3. During the laser printing process, what determines when the toner sticks to the drum and when it does not stick to the drum?

During the writing phase, the uniform high charge is discharged only in the places where toner is meant to stick to the drum.

17. When you get a toner-low message, what can you do to extend the life of the toner cartridge before you replace the cartridge?

Gently shake the toner cartridge to redistribute the toner

5. Why is it less expensive to maintain an inkjet printer that has a black ink cartridge than one that does not?

If an inkjet printer does not have a black ink cartridge, then it combines all colors of ink to produce a dull black. Having a separate cartridge for black ink means that it prints a true black and, more importantly, does not use the more expensive colored ink. You can replace the black cartridge without also replacing the colored ink cartridge.

4. What type printer is most dependent on the quality paper it uses to get the best printing results?

Inkjet printer

7. What can you do to help a dot-matrix printer last longer?

Keep the print head cool.

10. How do you share a local printer with others in the workgroup?

Open the Printers or Printers and Faxes window. Right-click the printer you want to share and select Sharing from the shortcut menu.

16. How can you prove a printer problem is not with the printer itself, but lies with the network, computer, OS, or application?

Print a self-test page using printer controls

18. What causes a ghosted image on a printout?

The drum is not fully cleaned

20. What is likely the problem when a portion of a complicated page does not print?

The printer does not have enough memory

15. Where is the best place to look for a firmware upgrade for a printer?

The printer web site

13. Which printer language is new to Windows Vista?
