My HP Photosmart 3210 thinks the ink cartridge is still empty even though I have replaced it.

(The obvious) Replace the black cartridge. Even if ot says you have ink you could have a faulty cartridge, even if it has worked fine in the past. (The not so obvious) Clean your printheads/nozzles. Repeat the process a few times.

You could try to turn your printer off then back on.
This will reset the printer.

turn printer off. take all ink cartridges out. look at where the ink is dispensing to see if the tape is still on the cartridge of blocking the ink from coming out, if so remove. when touching the area where the ink comes out, be very careful.
look into the printer where the ink dispenses into the printer, look and see if anything is blocking the hole.
hope this works and good luck

Are you using "refilled" hp cartridges? If so, they may be interpreted as "empty" or a non-hp cartridge if the carrtidge shell was manufactured prior to the recent time that hp began coding the electrics on the same type cartridges. This can also happen if you are using "compatibles". If this is the case, try buying original new hp carts. If that is what you already have, return the cart to the store as defective and as for a replacement.

must be dryed ink on ink cartdrige, or dirty print-head (ink cartdrige) conntector.
try these :
To clean the print head from the control panel
1. Load letter or A4 unused plain white paper into the main tray.
2. Press Setup.
3. Press 5, then press 2.
This displays the Tools menu and then selects Clean Printhead.
or
To clean the ink cartridge contacts
1. Unplug the power cord from the back of the HP All-in-One.
2. Lift the ink cartridge access door.
3. Squeeze the tab below an ink cartridge to release the latch inside the HP All-in-One, and then lift the latch.
4. Inspect the ink cartridge contacts for ink and debris buildup.
5. Dip a clean foam rubber swab or lint-free cloth into distilled water, and squeeze any excess water from it.
6. Clean only the copper-colored contacts.
7. Place the ink cartridge back into the empty slot and press down on the gray latch until it clicks into place.
8. Repeat if necessary for the other ink cartridges.
9. Gently close the ink cartridge access door and plug the power cord into the back of the HP All-in-One.

I installed new cartriges, but my printer keeps giving me an error msg, Ink system has failed. Unable to copy, receive faxes, or print. Refer to printer documentation. Error: Oxc18a0206. What do I do now?

Remove the color cartridge, it will run on "Ink economy mode" or something like that. It WILL print from windows but the copier wouldn't work, displaying error. The copier needs both cartridges installed to work.

No you cannot. Each one of your cartridges is smart chipped. When this cartridge registers as empty it acts as an on/off switch thus turning the printer off.'

You need to replace the empty cartridge in order to print.

Go printer settings and check option to print only black.

These cartridges are really only ik resovoirs for the printer. It does have an ink flow sensor, though. If the printer does not recognize the ink level, it is possible that you got a cart with a bad chip. I refill these alot, and all you can really do is check the chip on the cart and make sure nothing is on the contacts...otherwise replace. A good step would be to put the old cart in and see what happens...
