  1. PC Support & Repair Chapter 14 Advanced Printers & Scanners

  2. 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.

  3. Safety Hazards • Moving large devices • 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!

  4. 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.

  5. Connect To Port • What ports can a printer/scanner connect to?

  6. 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

  7. 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

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

  9. Options & Settings • Global • Affects all documents printed • Per-Document • Page Setup or Printer Properties

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

  11. 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

  12. 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.

  13. 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

  14. 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

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

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

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

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

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

  20. 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

  21. 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

  22. Upgrade & Configure Printers & Scanners • Describe printer upgrades • Describe scanner optimization

  23. Printer Upgrades • RAM • 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

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

  25. 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

  26. 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.

  27. 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

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

  29. 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

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

  31. Common Problems

  32. Review- 9 Questions
