Awful grind noise when powering up printer/scanner

You'll need to replace the pickup roller.

Not too good news I'm afraid. It sound like the fuser gear has failed. Generally the fuser unit (hot section or hot rollers in the back) need to be replaced. Usually when the gear has worn or failed the fuser rollers are also worn and need to be replaced. The gear can be replaced seperately but is a very risky operation and usually results in parts in the fuser unit falling appart due to age and wear, so it is best done as a unit. If possible do not run the machine as it can cause damage to gears around the fuser unit. The best option is to find out how much a fuser unit and labour to fit would be at your local service centre.

Seems like the drum drive gear is bad, and is not meshing w/the drum causing it to strip the drum gear.

Mine was indeed a gear problem. Took off the top cover and poked around. Found two areas that may have caused the grinding.
1. The lower roller shaft had slid to the left out of it's groove. By removing the handset cradle (3 release tabs are accessed underneath the toner hatch.) I could loosen the "gear box" (a black contraption with all the gears inside) and then snug the bottom roller into proper position.
2. I removed the "gear box" to look around. Don't know if I dislodged one of the gears while doing so, but noticed one was dislodged ;-)
This required opening up the gear box by removing 2 screws and lifting off the motor. Then i could get at a gear that had come loose from a claw sort of piece. Note: the teeth of the loose gear needed to be on the motor side when sliding it back into the claw thingy. It seems to use a metal clip for friction control and perhaps proper spacing.

I noticed "some" wearing of gears, but doubt this is an issue. This machine has been used VERY hard for years and now, just by re-aligning things, it works once again.

My googling barely found any mention of troubleshooting this machine, so I shudder to think what finding parts would be like.

Remove the drum unit (and toner) shake it gently from side to side to make sure toner inside is evenly distributed...

Reinstall and try that
