CompTIA A+ 220-1002 Lesson 17:Installing Configuring and Troubleshooting Print Devices - Activity questions

Where on disk is the print file spooled in Windows?

%SystemRoot%\System32\Spool\Printers

What is the process of image transfer?

Passing paper between the photosensitive drum and the secondary or transfer corona wire or roller. This attracts the toner from the drum to the paper.

What makes the power supply in a printer different to that used in a PC?

A PC's Power Supply Unit (PSU) only needs to generate voltages up to 12 V DC. The charging and transfer corona wires/rollers in a laser printer require much higher voltages. To apply a 600 V charge to the drum, for instance, the corona wire must be charged to 1000 V.

What tool can you use to confirm that basic print functionality is available?

Print a test page by using the option in the setup wizard or on the General tab of the Printer Properties dialog box

What must you do before installing a new toner cartridge into a printer?

Remove the packing strips. The printer should also be turned off, and the old cartridge should be removed and placed into a sealed bag for recycling.

How would you track down the source of a paper jam?

Check the error message reported by the printer (this may be shown on the printer's console). It may indicate the location of the stuck pages. Otherwise, visually inspect the various feed and output mechanisms.

How is the imaging drum in a laser printer charged?

Applying a uniform high charge to the photosensitive drum using the primarycorona wire or roller

Which inks are typically used in the color printing process?

Cyan, Magenta, Yellow, and Black (CMYK). Some printers can use more inks.

If print jobs do not appear at the printer and the queue is clear, what could you try first to solve the problem?

Cycle the power on the printer.

You have installed an automatic duplex unit in an office laser printer. What configuration setting would you change to make the unit available for print jobs?

From Devices and Printers or Settings, select Printer Properties and then select the Device Settings tab. Select the Duplex Unit setting and select Installed.

What is the function of OCR?

Optical Character Recognition (OCR) software can convert a scanned image of text into a digital text file that can be edited in a text editor or word processor.

A thermal printer used to create labels for parts bins, kits, and boxes is jammed due to a label coming loose during printing. How should you resolve this problem?

Open the printer and locate the label that came off the backing. Remove the label and if there is any sticky residue, clean it with isopropyl alcohol (IPA) applied to a swab. Ensure the roll of labels is properly loaded and that there are no loose labels that might come loose again

Which components are provided as part of a laser printer maintenance kit?

The main component is a new fuser assembly. The kit will also usually contain a transfer/secondary charge roller plus paper transport rollers for each tray (pickup rollers and a new separation pad).

Paper is jamming in an inkjet printer.What could be causing this?

The paper might not be loaded squarely, there might be too much paper loaded into the tray, or the paper is creased or dirty.

What configuration information does a user need to use a print device connected to the same local network?

The print device's IP address or host name. You might note that vendor utilities can search for a connected device on the local network, so "None" could also be a correct answer.

What two types of print heads are used by inkjet printers?

Thermal and piezoelectric. The thermal type is also known by Canon's Bubble Jet trademark because of the way the print head creates an ink bubble by heating. Most other printer vendors use thermal technology but Epson printers use their piezoelectric pump-like process

What type of connection interface is a scanner most likely to use?

All modern scanners will support USB. Some might have an Ethernet network port (RJ-45) or even wireless (Wi-Fi and/or Bluetooth), though this is more typical of Multifunction Devices (MFD) than standalone scanners.

When you are purchasing a new printer, what would you need to decide between as you evaluate connections

Almost all new printers use USB, so the main consideration would be whether you needed support for a wireless or Ethernet connection.

What is an ASF?

An AutoSheet Feeder (ASF) allows the printer to load a sheet of paper from a tray, using pickup rollers to move the sheet and a separation pad to make sure only a single sheet is fed at one time

What type of imaging input device would be most useful for a Point-of-Sale (POS) system?

Barcode scanner.

What type of sensor is used to capture an image for conversion to a digital file?

Charge Coupled Device (CCD) or Complementary Metal Oxide Semiconductor(CMOS)

Where are you must likely to encounter thermal printers?

Direct thermal printers are typically used as handheld receipt printers. There are other thermal printer types. For example, dye sublimation printers are often used for photo printing

What effect does a worn photosensitive drum have on printing?

Faint printing.

True or false? To enable printer sharing via Windows, the print device must be connected to the Windows PC via an Ethernet or Wi-Fi link.

False—any print device can be shared via printer properties. The print device can be connected to the Windows print server over USB, Bluetooth, Ethernet, or Wi-Fi. Other clients connect to the printer via the share, however, so the Windows PC must be kept on to facilitate printing.

What type of printer technology is a dot matrix printer?

It is commonly described as an impact printer.

What effect does a dirty primary corona wire have on laser printing?

It leaves black stripes on the paper. If the charging corona does not apply the correct charge evenly to the drum, toner is attracted to the place where the charging failed, creating a black stripe all the way down the page.

What is the removal of the charge from the photosensitive drum by a laser called?

Laser imaging or writing.

Why is a laser printer better suited to most office printing tasks than an inkjet?

Laser printers are much faster, quieter, and better quality (the pages do not smear)than inkjets at this type of output. They also have lower running costs.

What types of paper/stationery can dot matrix printers use that laser and inkjet printers cannot?

Multi-part or continuous tractor-fed stationery and carbon copy paper.

You are setting up a print server and want to enable access for the widest range of Windows 7 machines possible. Should you install separate drivers for the Home and Enterprise editions?

No—there is no difference between editions in this regard. You do need to install drivers for x86 (32-bit) and x64 (64-bit) versions, though

You use three Windows applications that need to print to a Canon BJC-4300printer. How many printer drivers must you install?

One. Applications rely on the operating system to mediate access to devices. They do not need their own drivers.

A laser printer is producing white stripes on the paper. What could be causing this?

Poorly distributed toner or a damaged/worn transfer corona wire. If the secondary corona does not apply a charge evenly across the paper, less toner is attracted from the drum to the part of the sheet where charging failed. Note that if there are repetitive white or black marks (rather than stripes) that do not smudge, the issue is more likely to be dirt or grease on the drum

A user reports that the printed output is not up to the usual standards for her printer. You will need to resolve this issue so she can print her report. What is the overall process for troubleshooting this issue?

Print out a test page to see if you can reproduce the problem the user reported. If you see the same problem as reported by the user, identify the print defect, based on the type of printer, to resolve the problem. Document the steps you took to resolve the problem.

You need to restart the Print Spooler service on a Windows 7 machine. You have logged on as Administrator. What are your next steps?

Right-click Computer and select Manage. Select Services and Applications→Services. Right-click Print Spooler and select Restart

What should you do if you cannot delete a job stuck in the print queue?

Stop the print spooler service, delete the spooled file, then restart the spooler.

True or false? Any type of smartphone camera can be used to read a QR code.

TRUE

True or false? When you print 10 copies of an uncollated job, 10 copies of page one are printed, followed by 10 copies of page two, then 10 copies of page three, and so on.

TRUE

What considerations for locating a 3D printer do you have to make?

The 3D print process is sensitive to movement and vibration, so the printer must be located on a firm and stable surface. The process can also be affected by dust and the ambient temperature and humidity (especially variations and drafts). Finally, some printer types are fully exposed so there is some risk of burns from the high-heat elements. Ideally, the printer should not be accessible to untrained staff

What service should a network print device run to enable an Apple iPad to use the device over Wi-Fi?

The Bonjour service

You have been asked to perform basic maintenance on an inkjet printer. One of the users noticed that the colors are not printing correctly and that the bottom of some letters are not printing. What would you do?

Try using the printer's built-in cleaning cycle, and then replacing the ink cartridge. If these do not work, try using an after market cleaning product. Try using the printer properties sheet to check for print head alignment, color settings, and other settings.

You have been asked to perform basic maintenance on a printer in the Research and Development area. The dot matrix printer used to create shipping documents seems to be printing lighter than normal, and one of the pins seems to not be connecting near the center of the print head as there are blank areas in some letters and images. What maintenance should you perform?

Using the steps in the printer documentation, replace the ribbon in the printer and clean the print head. If this does not fix the problem, replace the print head.

Can inkjet printers use plain copy paper?

Yes, but this type of paper will not produce the best results. It is better to use paper designed for inkjets.

What do you need to create objects with an FDM-type 3D printer?

You will need spools of filament, usually made of some type of plastic, to create 3Dobjects on a print bed or build surface.
