Xerox workcentre 75xx low speed fuser vs high speed fuser

[savi0r]

Hello all. From my knowledge, the only difference between the xerox workcentre 75xx fusers, the low and high speed versions, is the logic board wich is mounted on them. I am trying to fit a 7535 fuser on a 7855 machine. Did someone tried anything similar?

The two models have different codes (604K62220, 604K62230) but the assembly is the same, different suppliers put it for both models.

knowing xerox like i do .. i would say the harness isn't the same and gearing won't last as long as the proper unit.

there's a chip model identifier in the fuser just swap it you should be good to go.

Careful -- The heat rods may be a different.

you mean the FUSER LAMPS?

that would kick an error.. along with thermostats and thermistors

Phil, when did the term fuser lamps start? I may still have a manual for a 2400. Swear they were heat rods.

I'm in old school group brother.unless they are a soft roller fuser the those are resistor heated.we always refer to them as fuser lamps

Come to think of it, I don't think the 75's & 78's use heat rods. I think it is some kind of induction heating system that is a mystery to me. Maybe somebody knows.

i have pulled enough of these bitches apart.. they have HEAT LAMPS... no induction heating ... actual GLASS LAMPS

Phil, Disassembled the heat belt (heat roll), and couldn't find any glass anywhere. Inside the belt are thermistors, wick, wiper, reinforcement, etc, but no glass. Huge copper coil near the belt though. My guess: Induction heating. There is a thin pressure plate that is fairly wide (curved to encompass a large area inside the belt), that probably is the heat "plate", since it is magnetic and the heat belt is not, and therefore the belt will probably not conduct eddy currents. If that is the case, induction heating will heat the inside plate fast because of its low mass, and the plate heats the belt fast because of the belt's low mass. Maybe an "inductive fuser heat engineer" will chime in.

These fusers are induction. There is no mystery or question about it, it was one of the biggest "marketing points" when these models were released. They have no lamps.

Up to 55ppm, they are self contained complete fusers. The 70ppm model is "half" a fuser with the other half permanently in the machine, because it doesn't wear out. Cost savings measure.

But this entire family, from the WorkCentre 7525 to the current models are induction.

Hey Coffee, is the belt or the plate (or both) the business part?

Re: Xerox workcentre 75xx low speed fuser vs high speed fuser

A quick search mentions that even nonmagnetic metals will get hot , so it may be both.

For those who are curious, so far, the only difference between them is that logic board. I switched them and all seems good now.
