Cleaning an inkjet printer
If an inkjet printer is giving you problems, here’s what to do:
Take out the ink-head or cartridge.
Gently clean the print head contacts with a little rubbing alcohol on a sponge swab.
Or you can put a little alcohol on a stiff bristle brush and brush the contacts. After brushing, run a little of the alcohol over the print head to rinse off broken bristles. Don’t worry. It evaporates very quickly
Wipe excess ink off the nozzles.
Put the cartridge back in.
Start a print test to make sure you’ve gotten rid of excess ink.
If this doesn’t work, put in a new ink cartridge. That should take care of the problem.
Cleaning a laser printer
Laser printers have a corona wire that distributes toner. Use the illustrations in your printer manual to find out where it is. Here’s how to clean the corona wire:
Unplug the printer and turn it off.
Let it cool down.
Blow out dust from around the drum and corona wire.
Use canned air, a vacuum cleaner nozzle, or a blow dryer.
Dampen a cotton swab with rubbing alcohol.
Gently rub the swab along corona wire to remove built-up toner and dust that is still on the wire.
