Introduction This chapter explores the functionality of printers and

scanners.

The chapter discusses safety hazards, configuration procedures, preventive maintenance, and printer and scanner sharing.

Learn how to maintain, install, and repair these devices in both local and network configurations.


Hazards of Printers and ScannersAlways follow safety procedures when working on any

computer, printer or scanner. These rules will keep you and the equipment safe.

Always lift equipment by using the strength in your legs and knees, not your back.

Wear appropriate work clothes and shoes.

Do not wear loose jewelry or baggy clothes when servicing computer equipment.

Turn off equipment and allow it to cool before beginning any repairs on internal components.

Only qualified technicians should perform advanced repairs on laser printers due to high voltage potential.


Printer and Scanner Installation Connect it (USB, LPT, 1394, Print Server)

Use Windows XP’s PnP driver

Add software from manufacturer

Check for driver updates on the Internet

Change default settings

Run a test print

Scan a picture

Print the scanned picture


Computer Ports

Ports Characteristics

Serial Serial data transfer is the movement of single bits of information in a single cycle. A serial connection can be used for dot matrix printers.

Parallel Parallel data transfer is faster than serial data transfer. Parallel data transfer is the movement of multiple bits of information in a single cycle.

SCSI There are several common types of SCSI connections. SCSI ports can be DB 50, Mini DB 50, and DB 68. All of these ports may be male or female.

USBThe speed and simple setup has made USB very practical. When a USB device is added to a computer system supporting PnP, the device is automatically detected, and the computer starts the driver installation process.

FireWire

Firewire is a high-speed communication bus that interconnects digital devices such as printers, scanners, cameras, and hard drives. FireWire provides a single plug-and-socket connection on which up to 63 devices can be attached with data transfer speeds up to 400 Mbps.

Ethernet Connecting a printer to a network requires cabling that is compatible with both the existing network and the network port installed in the printer.


Drivers and SoftwareThe process of installing and updating a printer driver:

1. Determine the version of the installed printer driver and select a newer version to increase functionality.

2. Search the Internet to locate the latest driver version.

3. Download the driver and follow the instructions.

4. Install the driver.

5. Test the driver. To test the driver choose Start > Settings > Printers and

Faxes. Right-click the printer and choose Properties. Then choose Print Test Page. If the printer does not work, restart the computer and then try again.


Options and Default SettingsThe media control options set the way a printer manages

media:

Input paper tray selection

Output path selection

Media size and orientation

Paper weight selection

The printer output options manage how the ink or toner goes on the media:

Color management

Use the Print Test Page option from Windows

Print speed


Global and Per-Document MethodsGlobal method sets options to affect all documents.

To change the configuration of a global printer, select Start > Control Panel > Printers and Faxes and right-click the individual printer.

Per-Document method sets options to affect a single document.

To change the printer settings, keep the document open and select File > Page Setup.

Alter the colors, print quality, paper direction, and margin size for the document that you are printing without changing the default settings.


Verify FunctionalityInstallation is complete only after successfully testing all

device functions.

Print double-sided documents

Use different types of paper trays

Change the settings of a color printer so that it prints in black and white or grayscale to print draft copies of documents

Change scanner's scan resolution

Edit scanned images of saved documents

Use an optical character recognition (OCR) application


Shared PrinterThe computer that is connected to the printer can serve as the

print server.

Confirm printer sharing software is installed on the computer

The computer must know which printer to share

Go to the Printers folder

Right-click the printer to share

Select Properties

Click the Sharing tab

Select Share this printer option

Assign the printer a name


Types of Print ServersA print server has three functions.

1. Provide client access

2. Administrate print jobs

Storing jobs in a queue until the print device is ready, and then feeding or spooling the print information to the printer

3. Provide feedback to the users

Notification that a print job is finished, or an error message

There are three kinds of print servers:

Network print server devices

Dedicated PC print servers

Computer-shared printers


Configure Computer to Share a PrinterConfigure the computer attached to the printer to share the printer

with other network users.

1. Go to Start > Control Panel > Printers and Other Hardware > Printers and Faxes.

2. Select the printer you wish to share. The Printer Tasks box will appear on the left.

3. Select Share this printer. The Printer Properties dialog box for that printer will display.

4. Select the Sharing tab. Select Share this printer and enter the desired share name. This is the name that the printer will appear as to other users.

5. Verify that sharing has been successful. Return to the Printers and Faxes folder and note the printer icon now has a hand under it indicating the printer is now shared.


Connecting Others to Shared PrinterOther users on the network can now connect to the shared

printer:

1. Go to Start > Control Panel > Printers and other Hardware > Add a Printer.

2. The Add Printer wizard will appear. Click Next.

3. Select A network printer, or a printer attached to another computer. Click Next.

4. Type in the name of the printer, or browse for it on the network using the Next button.

5. After selecting the printer, a virtual printer port is created and displayed in the Add a Printer window. The required print drivers will be downloaded from the print server and installed on the computer. The wizard will then finish the installation.


Upgrade Printers and Scanners Some printers can be expanded to

print faster and to accommodate more print jobs by adding hardware.

The hardware may include additional paper trays, sheet feeders, network cards, and expansion memory.

Scanners can also be configured to do more to meet customer needs.

Examples for scanner optimization include color correction and resizing.


Printer Upgrades Improves printing speed

Preventive Maintenance Techniques

Decrease downtime and increase the service life of the components

Schedule maintenance according to vendor guidelines

Maintain a suitable environment for printers and scanners

Follow appropriate cleaning methods

Check the capacity of ink cartridges and toners


Maintenance ScheduleA laser printer maintenance

kit may contain:

Fuser assembly

Transfer rollers

Separation pads

Pickup rollers

When installing new parts or replacing toners and cartridges, visually inspect all internal components:

Remove bits of paper and dust

Clean spilled ink

Look for any worn gears, cracked plastic, or broken parts


Operating Environment GuidelinesPrinters and scanners are affected by temperature,

humidity, and electrical interference.

Keep paper dry

Keep printer in a cool, dust-free environment

Store toner in a clean, dry environment

Clean glass on scanners

Keep printers ventilated


Printer Maintenance CAUTION: Remember to unplug scanners and printers

before cleaning to prevent danger from high voltage.

Using a damp cloth wipe clean the exterior.

Use the utility supplied with the printer to clean the print heads. Afterward, test them to confirm they are clean.

On inkjet printers, clean the paper-handling machinery with a damp cloth.

CAUTION: Do not touch the drum of a laser printer while cleaning.

Use a specially designed vacuum cleaner to clean a laser printer.


Scanner Maintenance CAUTION: Remember to unplug scanners and printers

before cleaning to prevent danger from high voltage.

Using a damp cloth wipe clean the exterior.

On flatbed scanners, keep the lid closed when the scanner is not in use to prevent dust build-up and accidental fingertip smudges.

Consult the user guide for the manufacturer's cleaning recommendations of the glass.

Usually, use a glass cleaner and a soft cloth to protect the glass from scratching.

Check the manual for instructions on how to open the unit or remove the glass from the scanner.


Ink Cartridges and Toners When an inkjet printer

needs ink, it produces blank pages.

When a laser printer needs ink, it begins to print very poor-quality printouts.

Some printers have LCD message screens or LED lights that warn users when ink supplies are low.

You can set the printer software to reduce the amount of ink or toner that the printer uses.
