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

   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.

2. 2. Which types of printers are referred to as page printers, because they receive their print job instructions as one page at a time?

   C,D. A page printer is a type of computer printer that prints a page at a time.

3. 3. Which of the following is not an advantage of a Universal Serial Bus(USB) printer interface? a. it has a higher transfer rate than a serial connection. b. it has a higher transfer rate than a parallel connection c. it automatically recognizes new devices d. it allows the printer to communicate with networks, servers, and workstations.

   D. the rate of transfer and the ability to automatically recognize new devices are two of the major advantages that make USB the current most popular type of printer interface.

4. 4. Which type of printers can be used with multipart forms? a. bubble jet b. laser c. thermal d. dot-matrix printers

   D. Of the choices listed, only dot-matrix printers are impact printers and therefore can be used with multipart forms

5. 5. Which step in the EP print process uses a laser to discharge selected areas of the photosensitive drum, shus forming an image on the drum? a. writing b. transferring c. developing d. cleaning

   A. the writing step uses a laser to discharge selected areas of the photosensitive drum, thus forming an image on the drum.

6. 6. Which of the following are page- description languages? Select all that apply a. page description language(PDL) b. postScrips c. PageScript d. Printer Control Language(PCL)

   B,D. Of those listed, only PostScript and PCL are page description languages. There is no PDL or PageScript.

7. 7. What voltages does the corona wire or corona roller hold? a. +600VDC b. -600VDC c. 0VDC D -100VDC

   A. For the toner(which has a charge of -100VDC to be transferred from the print drum (which is -600VDC) to the paper, there must be a positive, or opposite, charge of greater difference to break the -100VDC charge from the drum.

8. 8. Which device in a bubble-jet printer contains the printhead? a. ink cartridge b. toner cartridge c. daisy wheel d. paper tray

   A. In a bubble-jet printer, the ink cartridge is the actual printhead. This is where the ink is expelled to form letters or graphics.

9. 9. What is the correct order of the steps in the EP print process? a. developing, writing, transfer, fusing, charging, cleaning b. charging, writing, developing, transferring, fusing, cleaning c. transferring, writing, developing, charging, cleaning, fusing d. cleaning, charging, writing, developing, transferring, fusing

   D. clean, charge, write, develop, transfer, fuse

10. 10. Any printer that uses the electrophotographic process contains how many standard assemblies?

    D There are 9 standard assemblies in an EP printer.

11. 11. What is included in the EP laser printer toner cartridge? Check all that apply. A. toner b. print drum c. laser d. cleaning blade.

    A,B,D in an EP laser printer toner cartridge, the toner, print drum, and cleaning blade are all contained in the toner cartridge.

12. 12. what happens during the developing stage of a 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 paper on the drum d. 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 and image of the page on the drum in the writing stage. An electrostatic charge is applied to the paper to attract toner in the transferring stage, which happens immediately after the developing stage.

13. 13. which of the following are possible interfaces for printers? select all that apply. a. parallel b. mouse port c. serial d. network

    A,C,D Printers can communicat via parallel, serial, USB, infrared, SCSI, 1394b, wireless, and network connections.

14. 14. the basis weight is the weight in pounds of 500 sheets of bond paper for what size of paper?

    C. The basis weight is the weight in pounds of 500 sheets of bond 17x22 inch paper.

15. 15. Which printer contains a wheel that looks like a flower with raised letters and symbols on each petal? a. bubble jet b. daisy wheel printer c. dot matrix printer d. laser printer

    b. the daisy- wheel printer gets its name because it contains a wheel with raised letters and symbols on each "petal"

16. 16. what part of a laser printer supplies the voltages for the charging and transfer corona assemblies? a. High voltage power supply(HPVS) b. DC power supply(DCPS) c. controller circuitry d. transfer corona

    A. The high voltage power supply is the part of the laser printer that supplies the voltages for the charging and transfer corona assemblies.

17. 17. Which printer part gets the toner from the photosensitive drum onto the paper? a. laser scanning assembly b. fusing assembly c. corona assembly d. drum

    C. the transfer corona assembly gets the toner from the photosensitive drum onto the paper. for some printers, this is a transfer corona wire, and for others, it is a transfer corona roller.

18. 18. LED page printers differ from EP process laser printers in which step? a. writing b. chargin c. fusing d. cleaning e. developing f. transferring

    a. LED page printers differ from EP process laser printers in the writing step. They use a different process to write the image on the EP drum.

19. 19. which step in the laser printer printing process occurs immediately after the writing phase? a. charging b. fusing c. transferring d. developing

    D. Developing happens after writing. The correct order is clean, charge, write, develop, transfer, and fuse.

20. 20. which assembly permanently presses the toner into the paper? a. transfer corona b. fuser c. printer controller circuitry d. paper transport assembly

    B. The fuser assembly presses and melts the toner into the paper. The transfer corona transfers the toner from the drum to the paper. The printer controller circuitry converts signals from the PC into signals for the various printer assemblies. The paper transport assembly controls the movement of the paper through the printer.
