Multifunction Peripherals Ø A multifunction peripheral (MFP) is a single device that servers several functions, including printing – Scanner – Fax machine – Copier Ø Best practice is to purchase one machine for one purpose Chapter 7: Supporting Printers 13
How Windows Handles Print Jobs Chapter 7: Supporting Printers 14
Local and Network Printers Ø A local printer is connected directly to a computer by way of a wireless connection or by a cable that connects to a parallel, serial, USB, SCSI, or Fire. Wire port Ø A network printer is a device that can be connected to a network and is accessible to a computer by way of a network Ø The default printer is the one Windows prints to unless another printer is selected Chapter 7: Supporting Printers 15
Installing a Local Printer Using a Cable Ø Physically attach the printer cable to the computer Ø Install the printer driver, either by having Windows install the driver or by using the printer manufacturer’s installation software Ø If your printer came with printer management software, install it Ø Print a test page to confirm that the driver is installed properly Chapter 7: Supporting Printers 16
Installing a Local Printer Using a Wireless Connection Chapter 7: Supporting Printers 17
Installing a Local Printer Using a Bluetooth Wireless Connection Ø Turn the printer off Ø Install the printer drivers using the manufacturer’s installation software Ø If you are using a wireless Bluetooth printing kit, – Plug the Bluetooth adapter into the USB port or insert it into the PC Card slot on the computer – Connect the printer adapter to the printer’s parallel port and, if needed, connect the power supply and plug it in. Ø Turn the printer on Ø Print a test page Chapter 7: Supporting Printers 18
Sharing a Network Printer Chapter 7: Supporting Printers 19
Connecting to a Shared Printer Chapter 7: Supporting Printers 20
Printer Maintenance Ø Ensure that the consumables (paper, ink, ribbons, color sticks, toner cartridges, and ink cartridges) are on hand Ø Research the printer documentation for specific maintenance procedures and how often you should perform them – Printer maintenance kit Ø Clean the printer with a damp cloth on the outside and a dry cloth on the inside Chapter 7: Supporting Printers 21
Printer Maintenance Chapter 7: Supporting Printers 22
General Printer Troubleshooting Chapter 7: Supporting Printers 23
Problems with the Printer Itself Ø To eliminate the printer as the problem, first check that the printer is on and then print a self -test page Ø If the self-test page doesn’t print or the information on the page is incorrect, you should troubleshoot the printer itself Chapter 7: Supporting Printers 24
Problems with the Printer Itself Chapter 7: Supporting Printers 25
Problems with the Printer Cable Ø If the printer self-test worked, try printing a test page from the printer Properties window Ø If the test page does not print: – Check the cable connections – Try the above step using a different printer cable – Try printing from a different PC with the cable in question Ø Enter CMOS setup and verify the printer port isn’t disabled Chapter 7: Supporting Printers 26
Problems with the Wireless Connection Ø Try printing a test page from the print adapter Ø Check for signal interference Ø Shorten the distance between the PC and the printer Ø Check that the printer adapter is connected to the printer securely Ø Check the power cable and connections Chapter 7: Supporting Printers 27
Problems with Laser Printers: Issues with Print Quality Ø If you suspect the printer is overheated, unplug it and allow it to cool Ø Remove the toner cartridge and gently rock it from side to redistribute the toner Ø Try replacing the toner cartridge Ø Extreme humidity may cause the toner to clump in the cartridge and give a low toner message – Consider a dehumidifier for the room where your printer is located Chapter 7: Supporting Printers 28
Problems with Laser Printers: Issues with Print Quality Ø Low-grade paper can result in poor print quality Ø You may need to clean the printer Ø Consider whether or not the printer requires routine maintenance Chapter 7: Supporting Printers 29
A Paper Jam Occurs or Paper Out Message Appears Ø Check for jammed paper from both the paper tray and the output bin Ø If there is no jammed paper, then remove the tray and check the metal plate at the bottom of the tray. If it cannot move up and down freely, replace the tray Ø When you insert the tray in the printer, check to see if the printer lifts the metal plate as the tray is inserted. If it does not, the lift mechanism might need repair Chapter 7: Supporting Printers 30
Printer Stays in Warm-Up Mode Ø Turn off the printer and disconnect the cable to the computer. Turn on the printer. If it now displays a Ready message, the problem is communication between the printer and computer Ø Verify that the cable is connected to the correct printer port, for example to a parallel port or USB port Ø Verify that data to the installed printer is being sent to the correct port Ø Replace the cable Chapter 7: Supporting Printers 31
Printing is Slow Ø Space is needed on the hard drive of the computer that queues and manages print jobs. Clean unneeded files from the drive or, if necessary, install a larger drive Ø Add more memory to the printer, following the directions in the printer manual Ø Lower the printer resolution and the print quality Chapter 7: Supporting Printers 32
A Portion of the Page Does Not Print Ø Printer may not have enough memory to hold the entire page – The solution is to install more memory in the printer Ø Print a self-test page to verify how much memory is installed and then check the printer guide to determine how much memory the printer can support and what kind of memory to buy Chapter 7: Supporting Printers 33
Problems with Ink-jet Printers Ø Check if the ink supply is low or if any of the cartridges have a partially clogged nozzle Ø In the printer’s Properties window, change the print quality to a higher dpi Ø Check that the print head is at the correct distance Ø Some printers have a little sponge near the carriage rest that can become clogged with ink. Remove and clean the sponge Ø If you are printing transparencies, try changing the fill pattern in your application Chapter 7: Supporting Printers 34
Troubleshooting Printing from Windows Ø The print spool might be stalled Ø Try to print a test page using the Printers window Ø Verify that the printer is online, or ready to accept print jobs Ø Verify that the printer cable or cable connections are tight and reboot the PC Ø Try removing and reinstalling the printer and printer drivers Chapter 7: Supporting Printers 35
Troubleshooting Printing from Application Software Ø Verify that the correct printer is selected in the Print Setup dialog box Ø Try printing a file from a different application Ø Delete any files in the print spool Ø Reboot the PC, and immediately try to print a Notepad document Ø Reopen the application giving the print error and attempt to print again Chapter 7: Supporting Printers 36
Troubleshooting Printing from Application Software Ø Try creating data in a new file and printing it Ø If you can print from other applications, consider reinstalling or upgrading the problem application Ø Close any applications that are not being used Ø Add more memory to the printer Ø Remove and reinstall the printer drivers Chapter 7: Supporting Printers 37
Troubleshooting Networked Printers Ø Be sure you are printing to the correct printer Ø Check to see if you can print to another network printer Ø Try printing a test page from the computer that has the printer attached to it locally Ø From the remote computer, delete the printer and reconnect it using My Network Places Ø Verify that you can access the computer to which the printer is attached Chapter 7: Supporting Printers 38
