HH-303 Printer/Scanner Not Perfectly Fine, Exactly

The scanner is mostly scanning, but may ask you to "check the scanner bed"; lifting the lid once or twice seems to make it happy.

The printer is mostly printing, but is still getting stuck at "Cancelling job" for reasons I've not yet determined; the only solution is to turn it off and back on at that point.

I am going to follow up with the tech-support people next week.
