Mr. Rubix Designed These Fusers

[WOETC]

Nearly agree regarding the Canon IRC3200 series, but NOTHING beats the IRC4080 series for me. I've never seen so much engineering for such a basic function. It can't be serviced in the field or the workshop, a replacement unit is around $2000, and there is about an hours work assembling the extras before it is ready to go into a machine.

Nightmare fusers. We've all done them.

Mita Ci-7500/7600 which I think was the same as a Minolta CF900/CF910. 3 lamps, bearings on the wrong sides of the frame, upper and lower rollers look the same but aren't, cam actuated oil pump and a liter of silicone oil.

Ricoh C900pro gets my vote.

Really? Other than being big & heavy, they're pretty straight forward. The two most complex I've worked on (other than Oce') were the Toshiba 810 and the Minolta BizHub 6500/1.

OK, I hate a Minolta Di 251/351 fuser. We at one time had 600 to 700 of these in the field. We had 40 whole built units that came with the contract, but the manager did not want to let them go, we were supposed to rebuild them. Well, through hitting the warehouse for used machines, and signing out the new ones when the manager was gone, I managed to go 8 years and only rebuild 1 of these bitches. I am sure I just jinxed myself by talking about it.

They weren't that bad. I've done probably 50 or more of those ; with practice you can get them down to about 30minutes start-finish.

Does everyone know about the little trick with these fusers to fix some fuse jam problems? You need to drop the height of the fuser entrance plate by filing away part of the little 'dicks' that determine the entrance height. I think this also fixed 'crinkling' of the copies too, but my memory escapes me.
