The following ink cartridges appear to be missing or damaged

Technician's Assistant: What's the brand and model of your printer?

HP Officejet L7780

Technician's Assistant: How long has this been going on with your OfficeJet?

Since yesterday I had a CISS system setup that broke, so I ordered regular cartridges (non-OEM) and they are not working

Technician's Assistant: Anything else you want the Printer Expert to know before I connect you?

I have cleaned the contacts with micro fiber cloth on the cartridges and the printer

Hi, I'm Nathan.
Sorry to hear that you're having trouble, but I'll do my best to help you. Please give me a few moments to review your details here.

There are a few possible causes of this issue, including a bad cartridge, internal debris/contamination, or a hardware failure (bad printhead, bad logic board, faulty sensor, etc).

Considering the generic cartridges you are using that is the most likely cause, these non oem inks are often defective right out of the box and even when they are recognized they are not recommended as they can damage the printer.

What we can try are some cleaning and reset steps.

First remove all of the ink cartridges, then clean the metal electrical contacts on the back, as well as where they mate up inside the printer, using qtips and rubbing alcohol. Dry well, then reseat the cartridges.

Then reset the machine:
unplug power at the wall outlet
wait 5 minutes
press and hold the power/on button for 60+ seconds
keep holding while plugging back in, and for another 60 seconds after, then release

Let me know the results, and I'll advise further if needed. If no change, as a next step, you'd need to replace the cartridges again, preferably with the proper oem inks.

Nathan
