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 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.

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?
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

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 Postscript (PS) HP Industry standard Faster
Output varies
Postscript (PS)
Adobe
Better quality
Consistent on all printers

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

10. Calibrations Scanner Printer Use software Scans a color chart
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 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.

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 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

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
Search for printer repair certification programs

28. 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

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
