Why will printer not recognize on of the print cartridges

If you insert the old cartridge, does it recognize it? If it does, then it's a problem with the new cartridge. Try to check if you already have taken out the protective tapes out of the cartridge.

If it still doesn't recognize the old cartridge, then it's a problem with the printer.

How to Reset an HP Inkjet Cartridge
Hi there
Instructions
Things You'll Need:
Adhesive tape

HP inkjet cartridge can be refilled easily, getting it to work again in the printer is another matter.
The contacts on the back of the cartridge are programmed to read the ink level, but they don't reset for the printer just because you add more ink.
You must get the printer to recognize the cartridge as new.
You can do this easily if you have two other old cartridges, or you can manipulate the contacts on the refilled cartridge.


Step 1
Insert the cartridge you refilled into the HP Printer.
Have the printer print an alignment page, thus recognizing the cartridge. The printer will still read the ink level as where it was before you refilled it.
Step 2
Remove the cartridge from the printer and replace it with another old cartridge.
Have the printer print an alignment page with this cartridge so it recognizes it as a different cartridge from the first one.
Step 3
Replace the second cartridge with a third one and run the same alignment page.
Because the printer only retains the memory of two Print Cartridges, it will erase the memory of the first (refilled) cartridge.
Step 4
Insert the refilled cartridge into the printer.
The printer will now recognize the cartridge as being full.

Next Steps
Step 1
Tape over the contact squares on the top left corner of the cartridge's contacts. Insert the cartridge into the printer and run an alignment page. Ignore any messages that might appear saying there is a problem with the cartridge.
Step 2
Take the cartridge out of the printer. Remove the tape from the left corner and tape over the contact squares on the top right corner. Place the cartridge backs in and run another alignment page.
Step 3
Remove and reinsert the cartridge, this time with no tape on any of the contacts. Check to see if the printer recognizes the cartridge as being full.
Step 4
Repeat the above steps if the cartridge is still shown as being empty.
This time, use the bottom corner contact squares instead of the top ones. If you are still unable to reset the cartridges, using multiple cartridges is likely the only way to do it.
jQuery('.article ol .image').each(function(i,e){ var $this = jQuery(this); $this.find('img').error(function(){ jQuery(this).remove(); $this.remove(); }); }); All I ask is to call back and just gave a vote, it will gave me some satisfaction to know am helping some one, so I will keep on helping.

You can't.The printer needs to recognized both cartridges to print, scan or copy.In your case the color cartridge is defective.You must replace it for using your printer.

My printer quit printing blue after I cleaned the print heads. What can I do? I tried recharging the cyan cartridge and cleaning the print heads again. it's still not working! GRR!!

Try this...shut down the printer. Insert new cartridge, let the printer cycle out with new cartridge. then reboot the computer. This should solve the problem. The cache in the printer will not cycle out. It wants to see the printer as a new entity

Your printer does not use #59 Cartridge!!!!

HP 56 black print cartridge (19 ml) C6656A HP 57 tri-color print cartridge (17 ml) C6657A HP 27 low capacity black print cartridge (10 ml) C8727A HP 28 low capacity tri-color print cartridge (8ml) C8728A

Take the black ink cartridge back to the person who refilled it. The Microchip that's on the cartridge was not reset properly that's why the printer is returning that error.

You can try some steps before you take it to them to verify it.
1: reseat (take out and put back in) the cartridges into place
2: buy another black cartridge just to check if it will be recognized by the printer, if it does recognize it we know the cartridge is defective. If a new cartridge is also not recognize, start to check your warranty option with the manufacturer...
