General ink cartridge help

Non HP ink can be used on this list of HP printers.
The below type is unlikely to work.

It is unlikely but possible that the ink is not genuine.

Check the expiration date of the ink and verify it is genuine. To check if an HP ink cartridge is genuine, look for a security label on the cartridge, scan the QR code on the label with your phone, and then go to HP's website hp.com/go/ok to verify the serial number on the label; if the label appears tampered or the serial number doesn't validate, the cartridge is likely not genuine.

My guess is the printhead needs to be cleaned due to dried out ink

Some printers have a printhead cleaning procedure.

To clean the printhead on an HP printer, access the printer settings through the HP Smart app, navigate to "Print Quality Tools," and select "Clean Printhead"; this will initiate a cleaning cycle where the printer will automatically run a cleaning process to clear any clogs in the printhead

This link shows cleaning the 8600 printhead and removal is shown here.

This is another type of printhead cleaning, different from the above.

Cleaning and removing ink is shown below by our "Scullery" team.

An HP original video on how to clean the printheads by our experts. Yes, this can get messy, but it works. If your ink levels are good but you are printing blank pages then this is likely the solution.

Official HP advice on cleaning.

let me know which of these worked, if any.

Hi BeemerBiker, the printer display on the 6600 as well as HP Smart both show Pinter or Print System problem, contact support, and I cannot do anything else.  Do you think the manual cartridge cleaning would solve that?  Thanks

That is the only thing I can think of since there are no other error messages.

The printer should always be to do a status report.
