You can clean the inside of the printer and the cartridges, but if you do, do so carefully. Manually cleaning the inside of the case usually isn’t necessary though, and it can cause more problems than it’s worth. If you must though, you can clean the cartridges:
1. Turn the printer on, open the cover, and let the cartridges move to the center of the printer. If that doesn’t work, you can get the cartridges to the desired position by choosing the option to change the printer cartridges in the printer’s preferences dialog box. Most of the time, it’s also okay to move them yourself if they don’t move there automatically.
2. Turn off the printer and unplug it. Open the printer door to view the inside.
3. Remove the empty cartridges, being careful not to touch any part of the cartridge or the printer. Place the cartridges on a piece of paper.
4. Run a cotton swab under water and squeeze out the excess.
5. Carefully clean each cartridge with the cotton swab, removing dust and dirt. Do not touch the nozzle plate or any of the circuitry.
6. Replace the cartridges, plug in, and then turn on the printer.
When cleaning a printer, keep these tips in mind:
* Don’t clean any part of the printer with alcohol, although people will tell you it’s a good way to remove dried ink. It’s too easy to mess up and damage something.
* Don’t remove the ink residue inside the case; this is normal.
* Don’t lubricate any parts with oil.
* Don’t work on the inside of the case with the printer plugged in.
* Don’t leave cartridges out for more than 30 minutes. They will dry up.
* Do purchase a printer cleaning kit if all else fails. Cleaning cartridge kits contain special cleaning fluid that can solve most print problems inexpensively.
