The issue here, and I have replicated on our 7545, is that if a scan jams during a job build - you have to cancel the job and lose what you previously scanned in. The option is there to Resume but when you choose that option, the screen flashes and you have to select Resume/Cancel again. Ultimately you have to choose Cancel to exit the job and your build is gone.
This also happens on a 5890
Can we SPAR this?
