Lanier 5622 SC 542

[Machinercylr]

I cannot understand . After finding the source of the error code, it keeps on blowing the same part after the second attempt. Cleared the code, found prints were coming out clean, then they started to smudge. Performed a developer change. Performed a developer mix, tested .Still getting smudged prints and this time gone back to a SC542 again. Removed the Fuser, dismantled to re examine the lamps, Thermisters and Thermostat assemblies. All checked out okay except for the same element in the thermostat assembly again. Also the case that holds this unit in place got so hot to the point that it melted and rubbed against the Heat roller. this is what caused the arc to burn-out the Thermostat element again in the same assembly. Before I purchase anymore parts and reset this to perform more tests, what am I over-looking? The Copier from Hell!Any Help is appreciated...PS I have your Manual Paul...Steve aka Machinercylr

I'd suggest replacing fuser assy. - After all that 'melting', I don't think you actually have a choice at this point.
After all these years, it's probably overdue anyway. That ought to take care of it. As for replacing developer. Are we talking about 2 separate problems here? I don't rebuild these units. I replace the entire PCU, because of my history that created all kinds of weird problems that arose on most of the units I attempted to do - particularly when you go messing around with various kinds of generic dev/drums/toner, etc.

Yes, I understand ,But, what if the same thing happened to newly replaced components?Thanks.

The thermostat is designed to function properly only if it is at the proper distance from the hot roller. If the holder for the thermostat becomes cracked or melted, the thermostat can be to close to the hot roller and will blow. I agree with sandmanmac as far as replacing the entire fusing unit. If instead you want to rebuild it then you should replace the hot roller, thermostats, thermostat holders, thermistors, and the fusing unit housing.

If by smudged prints you mean that the print smears due to incomplete fusing, then you may also have a problem with the pressure between the hot roller and the pressure roller. All the more reason to replace the entire fusing unit.

Re: Lanier 5622 SC 542

I agree with changing the fuser. Kind of sounds like initially the part of the fuser casing that holds the heat roller bearing in place (gear side of the roller) broke. That would account for the smudging at least. Probably the SC542 error code as well.
Best guess about the melting is that you chose to reset the error code without resolving the problem that caused it correctly, the machine locks up for SC54x series error codes precisely to prevent that. It's just a guess, though.

Only down side is a fuser for a Russian this old might be difficult to come by and a little on the expensive side.

Shouldn't be a problem to pick one up used, for next to nothing. (It sure wouldn't be here). Plus it's the same as the newer (Ricoh) 2027/2510/3025, etc.

The rib in the lower fuser-frame that holds the bearing in position on Russians is notorious for cracking or breaking, causing the hot-roller to drift and apply uneven pressure between hot-roller and press-roller. In extreme cases it can cause the lamp to short-out and blow the PSU. I would check to see if the lower fuser frame is not cracked.

Re: Lanier 5622 SC 542

As was already mentioned, replace the fuser. The heat roller bear holder is probably broken off and the rollers, thermisters, thermostat and housing would need to be replaced.
Also as mentioned the developer has nothing to do with this sc code.

Re: Lanier 5622 SC 542

As mentioned above, if the plastic rib in the lower fusing frame has broken off, this allows the fuser roller to shift in the frame which causes problems ranging from incomplete fusing of the image to rubbing of the fuser roller against the frame and SC codes from improper distance to the thermostat.

My field fix for this problem is to remove the ground screw from the hot roller stripper plate and replace it with a long screw. This hold the bearing (and fuser roller) in place so it does not shift sideways. I use the screw from the end of the A2309510 drum that holds the bearing in place. Works perfectly.
