How to Fix a Computer Printer

You try to print a document from your computer, but nothing
happens. Or worse yet, the printer jams or flashes its lights. In these
situations, you need the know-how to fix your printer. Fortunately, here are a
few solutions to common printer problems.
Check printed pages for
problems
If your computer prints, but the result isn’t good, check for
these issues:
Dark
vertical or horizontal lines: May be caused by a dirty or damaged print head (inkjet
printer), contamination of components (laser printer), or low ink or toner
levels (both types). On a laser printer, these lines may also be caused by a
scratch or other damage on the drum, which usually is part of the laser
cartridge that’s replaced when toner is depleted.
Uneven
print tones: Usually indicate
low ink or toner. On a laser printer, other possible causes are damage to the
photoreceptor or a light leak into the receptor from a nearby lamp or window.
White
vertical lines (laser printers): May be caused by damage to the toner cartridge or debris in the
path between the cartridge and the drum. Remove the obstacles or replace the
cartridge.
Black
or white blotches: May indicate
contamination of the drum or the fusing roller. The drum isn’t easy to clean;
fix the problem by replacing the cartridge.
Streaky
lines (laser printers): Tell
you that toner needs to be cleaned off the printer’s rollers or electrostatic
parts.
Low
resolution or dropouts (inkjet printers): May indicate that the tiny ink nozzles on the print head
of an inkjet printer are clogged. Many printers include a utility for cleaning
the inkjet head.
Test the printer’s hardware
Make sure that the printer is turned on and plugged into a live
electrical outlet. Then try these steps:
1.Check
the printer’s paper and ink levels.
Some printers stop printing when you run out but don’t tell you
the problem. Study the printer’s instruction manual to find the meaning of any
error lights on the printer or messages on your PC’s
monitor.
2.Check
for a paper jam.
Paper jams are usually caused by debris stuck in the paper path,
high humidity, or paper that’s not the right weight, grade, or type.
3.Run
the printer’s built-in self-test.
If the self-test fails, and the test program makes no
suggestions about repairs, the printer may need professional servicing. (If its
warranty has expired, replacing it probably makes more economic sense than
repairing it.)
4.If
the self-test works, print a test page.
To send the test page, choose Start→Control Panel→Printers and
Faxes (Windows XP), Start→Settings→Printers (Vista), or Start→Devices and
Printers (Windows 7).
Right-
click the printer’s
icon and choose Properties (XP and Vista) or Printer Properties
(Windows 7) from the shortcut menu. The printer’s Properties dialog box opens.
On the General tab, click the Print Test Page button.
If the test page prints successfully, your problem is most
likely a setting within a program, such as your word processor. Try resetting
the program’s printer options.
If the test page doesn’t print, click the Troubleshoot Printer
Problems link in the test-page confirmation message. The resulting help
screen
presents the most likely problems and helps you find the support
Web site for your particular brand of printer.
5.Switch
printer cables and then print a test page again.
If the printer works, the original cable has failed and should
be replaced.
6.Connect
the printer cable to a different USBport.
To test the port you use to connect to the printer, plug in
another device to see whether the system recognizes its presence.
7.Check
Device Manager.
See whether it’s reporting any hardware failures or indicating a
problem with any port or
printerdrivers.
8.Hook
the printer up to another computer.
That way, you know it’s working properly and can see whether
it’ll print.
