  1. PC Support & Repair

    Chapter 7 Fundamental Printers & Scanners
  2. Objectives After completing this chapter, you will meet these objectives: Describe the types of printers currently available. Describe the installation and configuration process for printers. Describe the types of scanners currently available. Describe the installation and configuration process for scanners. Identify and apply common preventive maintenance techniques for printers and scanners. Troubleshoot printers and scanners.
  3. Printers Customers will ask you for help with: Selecting a printer Installing and configuring a printer Troubleshooting a printer
  4. Describe Printers Available Describe characteristics and capabilities of printers. Describe printer-to-computer interfaces. Describe laser printers. Describe impact printers. Describe inkjet printers. Describe solid-ink printers. Describe other printer types.
  5. Printers What are the two main types of printers bought today? Laser Inkjet What do you look for in a printer?
  6. Printer Features Speed: Pages Per Minute (ppm) Inkjet may be slower than laser Color or B&W Uses CMYK Inkjet combines colors for a dot Quality: dpi More dpi= higher resolution High-quality ink/toner & paper
  7. Printer Features Reliability Warranty & what is covered Scheduled servicing after so long Mean time between failures (MTBF) – average length of time the printer works without failing TCO Initial purchase price Cost of supplies, such as paper and ink Price per page Maintenance costs Warranty costs When calculating the TCO, you should also consider the amount of material printed and the expected lifetime of the printer.
  8. Basic TCO Over 3 years HP LaserJet P2035n Cost of printer: Monthly duty cycle: Cost of Toner: How many pages for toner: Output in class: 1000 pages/month TCO Over 3 years:
  9. Printer to Computer Interfaces Serial OLD 1 bit at a time Dot matrix Parallel Multiple bits, wider path than serial IEEE 1284 standard EPP* & ECP operation modes for communication Bi-directional data path
  10. Printer to Computer Interfaces SCSI Parallel communication that’s faster Copier, high speed printer USB PnP Firewire IEEE 1394 (iLink) Up to 63 devices High-speed up to 400Mbps Hot-swap
  11. Printer to Computer Interfaces Ethernet For network access Wireless Infrared Both must have, line of sight, 12ft Bluetooth Short range Wi-Fi IEEE 802.11b,g,n 11Mbps, 54Mbps, 108Mbps
  12. Review What are the three popular IEEE Wi-Fi standards? 802.11b,g,n A printer’s image quality is measured in what? Dpi What is the IEEE standard for the old parallel ports? IEEE 1284 What are the two IEEE 1284 bidirectional modes? EPP & ECP
  13. Review What is the IEEE standard for Firewire? IEEE 1394 Up to how many devices can Firewire have plugged into a single port? 63 What is another name for Firewire? iLink If you wanted a network printer, what two port/features would you look for? Ethernet or wireless
  14. Laser Printers See Handout
  15. Impact Printer Print head strikes inked ribbon Dot matrix Print head with pins Daisy wheel Wheel with characters A: Cheap ribbon, continuous feed paper, can print on carbon copy paper D: Noisy, low-resolution, slow
  16. Inkjet Printers Ink cartridges spray liquid ink onto paper through nozzles Thermal- steam forces ink out Piezoelectric- vibration controls ink flow Let ink dry for 15 seconds A: low cost, high res, quick to print D: nozzles can clog, ink $$, ink wet after print
  17. Thermal Printer Receipt printer, old fax machines Waxy paper Turns black when heated A: Small, few moving parts, longer life D: Paper $$, paper storage issues (temp & life), poor graphics
  18. Dye-Sublimation Printers High-quality photos Sheets of ink
  19. Solid Ink Printers High quality images Solid sticks of ink (no waste) Ink melts Sprayed through nozzles to a drum Drum transfers to paper A: Vibrant color prints , easy to use, many paper types, faster than inkjet D: Printer & ink are $$$, slow to warm up
  20. Printer Comparison
  21. Review Which printer can you use carbon-copy paper in? Impact Which printer can print photo quality pictures and is inexpensive? Inkjet Which printer has the most inexpensive consumable? Impact Which printer has vivid color prints, but is expensive & warms up slowly? Solid ink
  22. Review A drum, fuser, and toner are in what printer? Laser What printer takes liquid ink cartridges? Inkjet Which printer most environmentally friendly? Solid ink Which printer has nozzle that can get clogged? Inkjet
  23. Printer Installation & Configuration Describe how to set up a printer. Explain how to power and connect the device using a local or network port. Describe how to install and update the device driver, firmware, and RAM. Identify configuration options and default settings. Describe how to optimize printer performance. Describe how to print a test page. Describe how to share a printer
  24. Unpacking Make sure everything is in the box Remove all packing from inside printer Prepare ink/toner Place in area where it won’t overheat Put in paper Read instructions
  25. Connect To computer, network, or print server Local Printer- USB, parallel, serial Can be shared over network Network- wired or wireless Use correct cable Then connect power DO NOT plug into UPS Printer surge (when turned on) can damage UPS
  26. Install OS may detect & install driver Driver in box may be newer Driver allows communication & options Driver updates from mfgr Download, save, run, test Firmware Update Controls how printer operates Can download like a driver RAM upgrade Drivers Page
  27. Configuration Options Paper type – standard, draft, gloss, or photo Print quality – draft, normal, photo, or automatic Color printing, Black-and-white printing, Grayscale printing Paper size – standard paper sizes or envelopes and business cards Paper orientation – landscape or portrait Print layout – normal, banner, booklet, or poster Duplex – normal or two-sided printing
  28. Test Page Print one after install From Printers in OS From application like Word From Printer’s panel From command prompt *LAB*
  29. Share a Printer Printer connected to one PC shared with others on network How is this different than network printer? Click Share under Printer Properties
  30. Review Which printer would a store use for receipts? Thermal What software, in the printer itself, controls how the printer operates and can be upgraded? Firmware What could be included in an all-in-one device? Printer, scanner, copier, fax Where would you get an updated driver for your printer? The printer manufacturer’s website
  31. Review What standard is for parallel ports? IEEE 1284 What are the parallel port’s bidirectional modes? EPP, ECP What is the standard for Firewire? IEEE 1394 You typed up & saved a file called printertest.txt. What would you type in the command prompt to send that document to the printer? Print printertest.txt
  32. Scanners Describe scanner types, resolution, and interfaces. Describe all-in-one devices. Describe flatbed scanners. Describe handheld scanners. Describe drum scanners. Compare costs of different types of scanners.
  33. Scanners What do they do? Create an image Create text doc using OCR Resolution measured in dpi
  34. Types of Scanners All-In-One Print, scan, copy, fax Low cost, one cable If breaks, you lose all Not for heavy use Flatbed Some may have sheet feeders
  35. Types of Scanners Handheld scanners Drum scanners Used for high-end reproductions For archiving in museums
  36. Installing Scanners Explain how to power and connect a scanner. Describe how to install and update the device driver. Identify configuration options and default settings.
  37. Setup & Install Scanner Plug in AC & USB PnP should detect & install driver Install software with printer Update driver from web LAB Install printer
  38. Scanner Configuration & Settings Usually comes with software Editing photos Scanning text (OCR) Allows text to be manipulated Other: Color, resolution, one-touch Calibration For color matching
  39. Preventive Maintenance for Printers & Scanners Describe printer maintenance. Describe scanner maintenance.
  40. Printer Maintenance Need lots Unplug 1st! Clean print head/nozzles, align heads What helps? Choose the right paper Load right side, use right type Ink selection Wrong type might get poor quality prints Do not refill…may leak
  41. Scanner Maintenance Keep glass clean Apply cleaner on cloth, NOT glass Can clean inside Keep lid closed Don’t put stuff on top of scanner
  42. Troubleshooting Process
  43. Problem-Solution
