pixma: move MF56x0 to MP730 backend
tl;dr this change makes Canon MF5650 work.
long story: I pulled this MF5650 in a pretty good nick out of an e-waste dumpster.
upon trying to run scanimage it failed with ETIMEDOUT
, but the hardware sounded like it's doing the job, just 10-20 seconds late. a comment regarding CCD calibration in pixma_mp730.c
led me to believe that's what is happening - and sure it was.
the device is connected to Raspberry Pi 4 running arm64 Ubuntu 21.04. I've tested scanning in different resolutions from both the flatbed and the ADF, and have not discovered any issues.
I don't have an MF5630 but I'd be really surprised if it was any different, so I moved it too.
if there are additional tests I could do - please let me know.
