Now both scanner apps dont find the device anymore
and hplip-3.20.5.run still stops with error: Installation cannot continue without this dependency. Please manually install this dependency and re-run this installer.
You could try the one in Software, for sure - they are listed as the same version, one is 'stable' branch, one is the 'latest / edge' branch; I would choose the stable one though.
The hplip package already installed can stay for now - don't see it causing any issues at the moment. It may or may not be removed with the newer install from Software (3.22.10-1).
Those ones not found can be removed from the string and ran again - I'm looking for a driver now that may be of use.
(edit) Okay - found a driver:
That may help haha lemme take a look to see what it needs to install.. Just looks like a ./install.sh file to run - pretty easy. That's the ScanGear software though, since scanning is the question right now.
Aaaahhhh... weeeeell I'd say that's the problem, heh.
Well, I guess that's somewhat of an easy fix!
Or, off the link you posted:
In all PIXMA models other than G-series PIXMA models, you can disable the ink detection system with the empty ink cartridges or tanks installed by pressing the Stop button on the printer for at least five (5) seconds and then releasing it. In G-series PIXMA models, you can do so by pressing and then immediately releasing the Start, OK, or Resume button, or by following the instructions on the printer’s LCD screen.[1]
Ooohhhh.. The carts might have a chip on them; had experienced that before. Apparently there's a device you can use to reset the chip. It talks to the printer and then stores that info that says it's 'empty', then even after refilling it doesn't change.. That's another hurdle as well, darn..
