Thanks again for all the info everyone!
I've made my purchase. Ended up with a Cannon ImageClass MF4570dn Laser all-in-one. Got it for about $100 under retail online. I'm containing my excitement for after it arrives .. and actually WORKS.
Funny you mention the shaking thing. The first time I ever heard of that was just a few months ago. Was some commercial where a bunch of office guys are watching the new guy print some stuff .. he says "it's out of ink" ... and they reply, "just shake it" ... and he picks up the whole printer & starts shaking the hell out of it. I had no idea wtf they were talking about until I thought about it & figured that shaking the cartridge must get more prints. Was a funny commercial after that! ( I've never been in an office environment except to get hired ... & then soon afterward, fired. )
Anyway this thing supposedly handles 10K pages per month. If I said I do one tenth of that I'd be off-the-chart on the exaggeration scale. Hopefully this works out better than the last 2 Lexmarks I've owned. $80 for toner is a bitter pill to swallow though. I'm hoping this thing doesn't croak if I use some generic toner .... I'm afraid to try after this last fiasco.
We just tried to send a fax with the old one, & it sounded like someone dumped chunks of steel into a truck transmission.
That was the paper feeder on the top that mysteriously *censored* the bed along with the rest of the printer. Figured I'd be able to sell it to some electronics store on eBay ... but nothing works now! NOTHING! Talk about a chip ... geeesh!! Total self destruction.
It will now be relegated to target status.
