I have a HP 822 deskjet, and the ink cartridge started leaking. The printer was not used in a while and the ink has dried. I believe that I could clean the ink up if I could get the cover off the printer. Any one have any experience with this?Thanks

I havn't opened up this particular printer.
But I have opened up several others for a thourough cleaning.

Look for hidden screws on the bottom of the printer, or catches along the seams of the plastic parts.

Dis-assemble the printer as far asyou can.
Follow ESD precautions when handling the electronics.
Watch for parts with settings or adjustments. Mark them so that you can get the setting back if you need to take them apart.

Use only an electronics grade cleaner on any electronics parts that are ink covered.

Start your cleaning with hot water.
Progress to Isopropal Alcohol, and then to stronger solvents as necessary.
BE VERY CAUTIOUS WITH STRONG SOLVENTS AND PLASTIC PARTS!!! THE SOLVENT MAY SOFTEN OR DISOLVE THE PLASTIC!

Re-assemble with care.

There is a page at HPs site with procedures to perform a self test of the printer.
I recommend that you do so before connecting the printer to a PC.

Best Wishes
