Don't Ask Me About My Day: UPDATE

You may remember that I was in printer hell the other day and I hadn't really solved the problem of why my printer sounded like a strangled cat every time I tried to use it.

After some more disassembly it turns out that it was a small motor in the laser scanner asembly with a dry bearing. That's number 4 in the picture. The tipoff was when the noise would continue after the motor and geartrain would stopp running.

A shot of WD40 pushed into the bearing with some desktop compressed air did the job.
