Ink cartridges

[Jopofriend]

My ink cartridges are at least half full. My printer began showing "missing cartridge" message, so I took them out and reinstalled them. It printed a few more pages, then showed "incompatible cartridge" message. I have tried EVERYTHING to no avail. I have had the missing cartridge message before, but this is the first time for the incompatible message. When it happened before, I installed new cartridges and that solved the problem. So I decided to replace my good cartridges with some old ones that were lying around, and my printer works (with fading ink). BUT my cartridges are still half full. I cannot afford to keep buying cartridges and only using half the ink.

Welcome to the HP Forums. I would be happy to help you with your HP 74/HP 75 cartridge. I understand that you are getting “incompatible cartridge” error message and you have already done some preliminary troubleshooting. 

However, I will need a few details to provide an accurate solution,

• Provide the printer model number or the product number of the printer.

Meanwhile:

• Remove, inspect, and then reseat the problem cartridge.
• Clean the cartridge and carriage electrical contacts.
• Reset the printer.

Click here and follow the document to perform above mentioned steps.

Let me know if that works.

Cheers.

The printer is a C4345. Did you miss where I said "I have tried EVERYTHING to no avail"? I tried all of that several times. My old cartridges (that I removed several months ago) work fine other than being low on ink.

Thanks for the reply.

Superb job on trying the different steps to isolate the issue.

I request you to contact HP Phone support for further assistance on this.

Cheers.

That link was a dead end. They no longer support my printer, but my problem is not the printer. My problem is the ink cartridges. Is there a phone number I can call for that?

Hi @Jopofriend

So if these are genuine HP cartridges that are still within warranty I would advise contacting HP Support for replacements under warranty. You'll need to provide the warranty ends dates (lasermarked on to the cartridge body in YYYY/MM/DD format)

Can you please post back to let us know how you get on?

Thanks
