  • 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.
  • Customers will ask you for help with:

printer features1
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.
