Question about HP PSC 750 All-In-One InkJet Printer

1 Answer

HP PSC 750 - Gives message - check cartridge or wrong cartridge..

Recently I had a serious operation and was out of commission for more than two months. During this period my printer was not in use. The cartridge I had been using successfully is the same one invoking the messages above.
The command, "PRINT" causes an error message - wrong cartridge. Putting a new cartridge in - DITTO. Also the test did not print automa- tically. I ran the "SELF-TEST", and it printed a blurry test with false colors.
Would cleaning the heads help? If so, How?
thanks martin smith

You could try to clean with alcohol the metalic looking part of the cartridge. If this doen't work, you should replace it and try a new one. I would suspect the the ink has dried on the cartridge and is clogging the jets. .

My printer has decided that the black printer cartridge that has worked for months is the "incorrect cartridge". Figured it was a software problem, since my other printer now gives the same error...

I am having the same problem, I tried to replace the black cartridge and now it says it is the incorrect cartridge, so I put the old one back in and get the same error message.

Psc 750 was just fine & making beautiful copies, then it started saying the cartridges are wrong, I replaced cartridges & still the same message,

try to wipe the electrical contacts on both cartridges with damp tissue. If you find any ink on the tissue, also clean the corresponding contacts in the printer.
Install the cartridges back in and once clamped in, move each around slightly (from side to side).
Close the lid and see what happens. If still no joy, have the printer serviced.

hope this helps

I have a hp psc 750 and have just put a new black ink cartridge in and keep on getting the error message wrong black ink cartridge

Did you make sure you removed the plastic tape protection before installing the cartridge? Check to see if there is anything on the bottom of the unit. It could be the problem. Check the install instructions.

Printer always says "Remove and check color cartridge"

It must be your ruined catridge. Some times the wire connections are burned at the side of the catridge and you must thaw away it and buy a new color catridge.

Had the same problem. Cleaned the copper-colored "contacts" on the actual printer. Where the printer and the cartridge touch ... you will see them when you take the cartridge out. Hope that helps.
