Objectives After completing this chapter, you will meet these objectives: Describe potential safety hazards and safety procedures associated with printers and scanners. Install and configure a local printer and scanner. Describe how to share a printer and a scanner on a network. Upgrade and configure printers and scanners. Describe printer and scanner preventive maintenance techniques. Troubleshoot printers and scanners.

Safety Hazards Moving large devices Working on them Lift with legs & knees, not back No loose jewelry or baggy clothes Working on them Let them cool Fuser hot! DMP print head hot! Corona wire & transfer roller retain high voltage! Printers and scanners can be expensive. If you do not service printers correctly, or install the wrong part, you can damage them beyond repair. Identify the corona wire & fuser in a printer.

Install & configure a local printer/scanner Connect the device to a local port. Install and configure the driver and software. Configure options and default settings. Verify functionality.

Connect To Port What ports can a printer/scanner connect to? Serial- old, slow, DMP; Parallel- IEEE 1284, EPP/ECP bi-directional; USB- 1 port supports 127 devices, hot swappable, 1.0 up to 12Mbps, 2.0 up to 480Mbps; FireWire- IEEE 1394, 1 port supports up to 63 devices, also called iLink; RJ-45

Install & Configure Windows PnP will try and install driver May need the disk Find out the version & check for latest After install, print test page In Control Panel, right-click on printer, Properties If unreadable, might be wrong driver GDI (in Windows) outputs graphics to printer

Page Description Language The appearance of a document in a language that a printer can understand Software uses PDLs to send what’s on screen to the printer WYSIWYG

Printing Fonts- PDL PCL Postscript (PS) HP Industry standard Faster Output varies Postscript (PS) Adobe Better quality Consistent on all printers

Options & Settings Global Per-Document Affects all documents printed Page Setup or Printer Properties Print B&W or color, go to printer preferences

Calibrations Scanner Printer Use software Scans a color chart Aligns print heads

Verify Functionality- Printer Print double-sided documents Use different paper trays for different paper sizes Change settings of a color printer so that it prints in black and white or grayscale Print in draft mode Use the Print Test Page option from the printer Use the Print Test Page option from Windows Use the print function of an application

Verify Functionality- Scanner Scan a paper document using the buttons on the device Re-scan the document using the scanner software Change a scanner's scan resolution Edit scanned images of saved documents Use an optical character recognition (OCR) application For an all-in-one device, you should test all of the functions: Fax – Fax to another known working fax. Copy – Create a copy of a document. Scan – Scan a document. Print – Print a document.

Review In Windows, what manages the output of graphics to a printer? GDI What print option describes a user changing setting for each document sent to the printer? Per-document What two ports would a DMP connect to? Serial or parallel

Review What two laser printer components contain high voltages? Corona wire & transfer roller In a DMP, which part can be hot? Print head To add a printer in XP, under what section would you find it? Control Panel, Printers & Faxes

Sharing Printers & Scanners Describe types of print servers. Describe how to install network printer software and drivers on a computer.

Print Servers Allows many computers to share a printer Three kinds: Can also store jobs in queue Print/error notification Three kinds: Network print servers Dedicated PC print servers Computer-shared printers Printer is most common shared device.

Network Print Server Box Wired or wireless Frees up PC for other jobs May only allow network printing to an all-in-one device

PC Print Servers Dedicated PC to act as print server Needs good processor, HD space, RAM

Computer-Shared Printer Printer attached to PC Set to share Uses computer resources to share PC must be on to print

Installing a Network Printer Configure the computer with printer attached to share it Configure other computers to “see” it Still need drivers In list, enter name, or IP address

Review Which network printing method do you think is the cheapest? Computer shared What is a disadvantage of the above? Computer must be on When adding a network printer, what three ways can select one? Shown in list, by name, by IP address Which method would you use to setup a network printer and not have to worry about using a computer? Print server

Upgrade & Configure Printers & Scanners Describe printer upgrades Describe scanner optimization

Printer Upgrades RAM Other Upgrades More RAM=faster & better handle complex jobs Can buffer more jobs Other Upgrades Duplex printing Extra trays to hold more paper Specialized tray types for different media Network cards to access a wired or wireless network Firmware upgrades to add functionality or to fix bugs

Scanner Optimization Resolution & file format affects file size For web- low resolution & small size For printing- medium resolution For commercial printing- high resolution

Review It takes 5 minutes to print a large graphic. What can be done to lessen the time? Add more RAM On a scanner, which settings can affect the size of a saved file? Resolution & file format

Printer & Scanner Preventive Maintenance Determine scheduled maintenance according to vendor guidelines. Describe a suitable environment for printers and scanners. Describe cleaning methods. Describe how to check the capacity of ink cartridges and toners.

Maintenance Guidelines Use manufacturer supplies (not generic) Reset counters Visual inspection Bits of paper or dust Spilled ink/toner Lab 14.5.1 Search for printer repair certification programs

Printer Environment Laser printers get hot Keep paper dry Keep well ventilated Keep paper dry High humidity causes paper to absorb moisture Hard for toner to attach to paper Clean scanner glass

How to Clean Turn off printer Use damp cloth For inkjet, use utility to clean print heads For laser, use HEPA filter vacuum to clean toner DO NOT touch drum Use correct ink & paper May cause printer not to work

Check Ink & Toner Levels Look at LCD screen, LED lights, software utility Check counter & estimate Use draft mode

Common Problems 1- wrong driver, loose cable, no paper, paused or offline 2- dirty, wrong paper, humidity 3- toner/ink empty, nozzle clogged 4- not enough RAM 5- drum dirty or not being cleaned correctly
