My 3845 printer has been working OK but needed the black cartridge changed. I put in a new one, but with no response from the printer so I replaced the cartridge with another new cartridge. All I get is the green light blinking (or off completely). The built-in test system doesn't run either. I have checked all of the cables, they are OK, but even the HP Support Assistant now fails to find the printer. I have even tried re-installing it but to no avail. No error messages have shown at any time. Where do I go from here?
Solved! Go to Solution.

You could well be right insofar as the printer worked OK until Saturday evening. When I shut down, Windows stated that updates were being installed and not to switch off (a pretty standard occurrence). Next day, no printer! But how can I go back in time to fix it?

I'm not on Win 10 but there should be a recovery or restore function somewhere that lets you roll back to a previous date on the computer. Search for "restore" or "recovery". Should be in the control panel somewhere. Select a date prior to the update and see if that brings back your printer. It will warn you that this change cannot be undone and will show you what programs will be effected.
Maybe someone with more Win 10 experience will chime in and give better instructions.

I have just attempted to restore and/or recover my P/c but, although it took some time and on-screen signals seemed to show some action, it may or may not have changed anything. The printer still fails to run. I'm stumped. I even replaced the colour cartridge, not all that old an item, although it was the black which appeared to be getting low. Either way, none of them are funtioning and the only sign of 'life' is the green light which continues to flash as if it is out of paper or something such.

In a last-ditch stand this morning I switched my P/c on again and inserted a third, and my last, new cassette into my printer. Blow me down, it's running! I tried replacing the previous two cassettes but neither of them work so back to #3. However, at least I have a functioning printer again albeit at the cost of one-for-the-price-of-three cassettes. Oh, well, c'est la vie I suppose. But thanks for all of your interest and attempts to advise. Most grateful.
