CompTIA A+ IT Technician 220-602 - Quiz

 A network laser printer is configured to enable your department to print documents. When you try to print a large document with heavy graphics, the laser printer displays the memory overflow error. You are able to print smaller documents on this printer.


     
    


Questions and Answers
  • 1. 

    What can be the cause of the error?

    • A.

      The printer is nonfunctional and should be replaced.

    • B.

      The scanner mirror of the printer is dirty and should be cleaned.

    • C.

      There is not enough memory in the printer to print your documents.

    • D.

      The page printed is too complex for the printer to understand and print.

    Correct Answer
    C. There is not enough memory in the printer to print your documents.
    Explanation
    That's right. The memory overflow error is encountered when you attempt to print documents that are larger than the memory available in the printer. To resolve this error, you should increase the memory in the printer.

    The printer does not need to be replaced because you are able to print smaller documents on this printer.

    The scanner mirror of the printer is not dirty in this scenario. When the scanner mirror is dirty, the printer will usually print a partially blank page. In the scenario, you are able to easily print smaller documents.

    When the printed page is too complex, the printer is unable to print the pages as fast as generated by the print engine. To avoid this error, you should enable the Set Page Protect option in the printer properties. The Set Page Protect option can be configured to On or Auto. In this scenario, the printer is unable to print the document because the page is too complex for the printer to print. To get appropriate printing, either you need to simplify the page or configure the Set Page Protect option in the printer. The Set Page Protect option allows you to print a page that is complex for a printer to understand. You should switch off the Set Page Protect option after printing the complex page because this option degrades the printer performance.

    You are troubleshooting a laser printer that feeds multiple sheets of paper for each page it is supposed to print. Which component could be causing the problem? (Choose two.)

    • A.

      Paper Type

    • B.

      Primary corona

    • C.

      Feed mechanism

    • D.

      Photosensitive drum

    Correct Answer(s)
    A. Paper Type
    C. Feed mechanism
    Explanation
    The paper type could be causing the problem because if the printer is not compatible with the type of paper being used, it may not be able to properly feed and separate the sheets. The feed mechanism could also be causing the issue if it is not functioning correctly, as it may be pulling in more than one sheet at a time.

    You receive a technical support call from a department manager. She reports that the laser printer in her department prints only blank pages. A telephone interview reveals that the paper is not jamming in the printer and that the problem began occurring after the toner cartridge was replaced.What is the most likely cause of the problem?

    • A.

      The printer needs more RAM.

    • B.

      The feed rollers are defective.

    • C.

      The photosensitive drum was not fully discharged.

    • D.

      The sealing tape was not removed from the toner cartridge.

    Correct Answer
    D. The sealing tape was not removed from the toner cartridge.
    Explanation
    That's right. The sealing tape that is shipped with a toner cartridge must be removed before the cartridge is installed. Otherwise, toner will not be applied to the drum for transfer to the paper during the electrophotographic process. Other situations, such as a defective laser or corona wire, can cause blank pages to be ejected from the printer. However, in this scenario, the printing of blank pages happened only after the installation of the new toner cartridge, which implies a cause-and-effect relationship between the installation of the toner cartridge and the printing of blank pages.

    If a printer lacks sufficient random access memory (RAM), then portions of a printed page could appear blank, but it is unlikely that each page would be completely blank merely because of insufficient RAM. If portions of a printed page appear blank, then it is necessary either to adjust the print resolution to a lower value or to add additional memory to the printer.

    If feed rollers are defective, then distorted or wavy images are likely to result.

    If a laser printer's photosensitive drum is not fully discharged, then ghost images that are often separated by a regular distance may appear on the printed pages.

    When experiencing problems with a laser printer, you should first refer to the manual that accompanied the printer. It will include a section on the primary printer errors and possible fixes. A secondary resource for errors is the printer manufacturer's Web site.

    Your laser printer produces accurate images that smear easily. Which printer component should you examine?

    • A.

      Fuser

    • B.

      Feed roller

    • C.

      Transfer corona

    • D.

      Photosensitive drum

    Correct Answer
    A. Fuser
    Explanation
    The correct answer is A. A laser printer's fuser contains two rollers, which use heat and pressure to fuse an image onto paper. If the fuser subsystem fails to heat properly or supplies insufficient pressure, then the toner will merely rest on the surface of the paper and can be easily smeared. Toner is a powdery ink consisting of pigment, such as carbon black or iron, bound in a polymeric or waxy matrix. The transfer corona places the toner from the drum onto the paper through an electrostatic attraction process. If the fuser roller does not heat up, then you should look for a blown fuse. Another common problem with the fuser assembly is a pressure roller contaminated with toner. A contaminated pressure roller will cause black specks to appear on the back side of a printout. Cleaning the fuser rollers with a soft cloth and alcohol can occasionally resolve this problem; the cleaning should be performed after the rollers are allowed to cool briefly.

    Defective feed rollers can cause multiple sheets of paper to be fed simultaneously, sometimes resulting in a feed jam. Defective feed rollers can also cause the image to be compressed or expanded vertically.

    The transfer corona is a wire that transfers an attractive electrostatic charge to paper so that toner will transfer from the drum to the paper. Failure to keep the transfer corona clean can result in faded printouts.

    A laser printer's photosensitive drum has a cylindrical surface that is struck by laser light. The light writes a path on the drum and leaves an electrical charge wherever it strikes the drum, eventually placing the image of an entire page on the drum. If the drum is scratched or otherwise damaged, then the image that appears on paper will not match the page that was supposed to be printed. Running stapled paper through a laser printer can damage the drum and cause vertical lines to appear on the printout.

    Rate this question:

  • 5. 

    Which laser printer component can cause paper jams? (Choose two.)

    • A.

      Laser

    • B.

      Primary corona

    • C.

      Fusing rollers

    • D.

      Photosensitive drum

    Correct Answer(s)
    C. Fusing rollers
    D. pHotosensitive drum
    Explanation
    The correct answers are C and D. Paper jams can occur during the process of guiding paper through the fusing rollers, which use heat and pressure to prevent toner from smearing on a printed page. Most paper jams occur at the front end of the printer in the pickup area, where a single sheet is pulled from the stack in the tray. Other common areas where paper jams can occur include the registration area, where rollers synchronize the paper movement with the drum rotation, and any special paper-handling devices such as duplexers and collators.

    Other factors that can cause paper jams include using paper that is too thick or too thin, using paper that has the wrong dimensions, using coated paper, and using non-supported media such as transparencies. If a printer is jamming repeatedly, you should ensure that the print medium is supported by the printer.

    The primary corona and laser are unlikely to cause paper jams because these components do not guide paper physically through a printer.

    A customer reports that an inkjet printer connected to his Windows XP Professional computer is producing images with distorted colors. Orange, for instance, is printing as yellow, and purples are printing as blue. Sometimes these distortions appear in bands on the page.Which steps should you tell the client to take to resolve this problem? (Choose two.)

    • A.

      Select Draft mode

    • B.

      Clean the printhead

    • C.

      Replace the printer ribbon

    • D.

      Replace the inkjet cartridge

    Correct Answer(s)
    B. Clean the printhead
    D. Replace the inkjet cartridge
    Explanation
    The correct answers are B and D. From the description of the symptoms, you can deduce that the problem is occurring because either the printhead is clogged with ink or the inkjet cartridge is out or nearly out of red ink. Cleaning the printhead may resolve the problem, known as banding, which can occur when inkjet heads become clogged. If the inkjets clog frequently, then you should ask whether the printer is turned off at the printer itself or whether it is turned off at a power strip. When an inkjet printer is turned off at the printer, the printhead normally cleans itself and then moves to a parked position, which is sometimes referred to as a maintenance area. However, if the inkjet printer is turned off at a power strip, then the printhead is unable to move to the parked position and the nozzles are exposed to the air, where they can dry out.

    The Printer Properties dialog box provides access to settings such as Draft mode. Draft mode provides a lighter printout because fewer dots per inch are printed, which conserves ink. Another useful option in the Printer Properties dialog box of most inkjet printers is a setting that forces the printer to print with black ink only. When this selection is used, Web pages and documents with color graphics will be printed with the black ink cartridge only; color ink is generally more expensive than black ink.

    Printer ribbons are used in impact printers such as dot-matrix printers and are not included in inkjet printers. A dot-matrix printer uses an electromagnet to control individual pins in its printhead, which create output by striking the printer ribbon against the paper. Inkjet printheads do not contain pins.

    You replace a black ink cartridge in your inkjet printer, and now the printouts consist of jagged lines and characters.What is the first action you should take to resolve the problem?

    • A.

      Printer a test page.

    • B.

      Run a printer alignment program.

    • C.

      Run a printer diagnostics program.

    • D.

      Remove and reinstall the cartridge

    Correct Answer
    B. Run a printer alignment program.
    Explanation
    That's right. After you install a new printer cartridge in an inkjet printer, you should run the printer alignment program to align the inkjet printheads. This should allow the printer to produce clearer output. After you replace an ink cartridge and attempt to print, you will usually receive a message that recommends the running of the alignment program. You should also run the alignment program for your printer if you notice at any time that vertical or horizontal lines in your printer output are not aligned. The jagged printing is due to very small differences between the new and the original cartridges, and the alignment program is specifically designed to adjust for these differences.

    Printing a test page will simply produce more evidence of the need to align the cartridge without actually performing the alignment.

    A diagnostics program is generally used for troubleshooting, whereas an alignment program is generally used for maintenance.

    Removing and reinstalling the cartridge is unlikely to resolve the issue because the position of the new cartridge in the holder will remain the same.

    A user reports that his dot-matrix printer is printing dark and clear on the left side of the paper but that the print is very light on the right side of the paper. What should you do to correct this problem with the printer?

    • A.

      Adjust the platen

    • B.

      Replace the ribbon.

    • C.

      Clean the ink nozzle.

    • D.

      Align the print head.

    • E.

      Adjust the transfer roller

    Correct Answer
    A. Adjust the platen
    Explanation
    The correct answer is A. Dot-matrix printers use a platen (rubberized roller) to hold the paper in place and to help advance the continuous paper on which it prints. If the platen does not hold the paper evenly, the print will appear lighter as you move across the page. Adjusting the platen usually solves the problem.

    Although laser and ink-jet printers have largely replaced dot-matrix printers, they remain are the choice of commercial applications where continuous feed and multipart forms are required. This is because dot-matrix printers can print at very high-speed, and they use an impact method of printing that allows copies of the form to be created as the original prints. Laser and ink-jet printing technologies do not impact the paper, so you must create a second copy when required.

    John is using laser printer in his office for the last one year. John reports that he has frequent paper jam problems. What should you do to resolve this problem?

    • A.

      Print a test page.

    • B.

      Install a maintenance kit.

    • C.

      Replace DC power supply.

    • D.

      Replace the cartridge.

    Correct Answer
    B. Install a maintenance kit.
    Explanation
    That's right. Paper jam problems occur when a paper is stuck in the printer or due to malfunctioned pickup rollers and registration rollers in the printer. To resolve this problem, you should install a maintenance kit. Installing maintenance kit will replace paper pickup rollers and registration rollers that are responsible for moving the papers to the printer. Printer maintenance kit includes a fuser, a transfer roller, a pickup roller, a registration roller, and six feed rollers.

    Printing a test page will not resolve paper jam problem. A test page is printed to check proper functioning of the printer.

    Replacing a DC power supply will not resolve paper jam problem. DC power supply is used to provide power to the printer.

    Replacing the cartridge will not resolve a paper jam problem. You should replace the cartridge when you receive a black vertical line on the printed page.

    Before vacuuming the inside of a laser printer, what should you do first?

    • A.

      Remove the roller blade.

    • B.

      Remove the toner cartridge.

    • C.

      Remove the photosensitive drum.

    • D.

      Remove excess toner with a damp cloth.

    Correct Answer
    B. Remove the toner cartridge.
    Explanation
    The correct answer is B. You should remove the toner cartridge first. If you do not, you may have a larger mess than when you started. Using a damp cloth would be a mistake since the water can mix with the toner, again causing a larger mess than the one you started with.

    Which address do hardware vendors assign?

    • A.

      Internet zip code

    • B.

      Logical network address

    • C.

      Physical device addresss

    • D.

      Physical Internet address

    Correct Answer
    C. pHysical device addresss
    Explanation
    The correct answer is C. The physical device, or hardware, address is also referred to as the Media Access Control (MAC) address. A MAC address is a unique number that is assigned to a network interface card (NIC) card when the card is manufactured. No two computers on a network can have the same MAC address.

    The Data Link layer of the OSI model uses these addresses to communicate between devices on local network segments. Although these addresses are considered permanently assigned, some protocols enable them to be changed. An example of a MAC address is 00-AA-00-62-A1-09.

    • D.

      9840

    Correct Answer
    A. Super DLT (S-DLT)
    Explanation
    Super DLT (S-DLT) is the correct answer because it is a tape format that has a native capacity of 100 GB and supports transfer speeds from 10 to 40 MBps. Digital Linear tape (DLT) and Quarter-inch cartridge (QIC) are not mentioned to have the same specifications, and 9840 is not a tape format.
