MP C3002 'Replace Fusing Rollers Now' @185K

[Richariri]

Hello everyone,

I've just got back from a call where an MP C3002 is flagging up on screen (user notice, not an SC code) that it needs the fusing rollers replacing.

Thing is, it's only done 185K from new and the PM life of the fuser is at 300K.
I inspected the unit and it's clean as a whistle, in fact it looks real good for it's current mileage.

So i've reset the PM counter and left a note on the fuser to make sure the count doesn't get mixed up when it does fail, we can then see what the count is. Plus I've ordered a rebuild kit to be ready.

I was just wondering if anyone else has had this message flag up early?


I know these heat sleeves can cause problems depending on usage, but this customer is pretty low volume.

Set SP7-624-XXX to 0 (Not PM Maintenance)

The rollers and fusing sleeves on these models do not last well past, or even near sometimes, PM.

If it looks ok just reset the fuser pm counter

Yes, we've had a couple machines fail early, but not call for new parts early.

I'm a bit skeptical about turning this SP mode off as the PM calls are usually a good thing. Do you have any idea why it would call for part replacement ahead of the PM counter? I thought it issued a warning when there was around 10% left of the units life and this has called at around 50% of the PM count. Or do these machines simply have some fancy way of detecting wear on the rollers?

My guess is it goes by rotation life, for instance if a customer uses it as a fax machine and it only makes one or two prints at a time it will have many more rotations than someone that runs a 35 page copy or print job.

Maybe they run a lot of 11" X 17" prints and the machine isn't set for two clicks per each ledger sized sheet of paper?

Or, for something entirely different, is there a chance the rollers were damaged earlier, and changed by somebody else who didn't reset the PM counter? I've actually done that to myself once or twice.

Either one could result in the % Rotation being as much as double the % Page or more. I have frequently seen % rotation numbers that are at least twice the % page in the SMC data log report.

We have had a number of junior techs in the past who would not clear PM counters after replacing parts. Really screws up trying to know when the next one is due.

A3 double count is definitely on, I'm the main refurb engineer so I will check every single machine top to bottom before install.

As for rotations, I think we're onto a winner. The K PCU which has done the same pm count is showing 120 million rotations whilst the Fusing Unit is at 176 mill, why this would set off a replace fusing rollers message and not send a PM call to @remote is anybodies guess right now.

The customer doesn't use this machine heavily, and it's all 1-30 page prints a few times per day so maybe all the process controls when it turns on after sitting for so long causes all the extra rotations, still stumped about why it's flagging up a message based on rotations and not PM count.

We had an upset with techs only using 'manual new unit reset' instead of the correct 'reset PM parts' SC's, but this is my machine so I'm certain that the PM counters are correct.

Thanks for the help guys.

EDIT: just double checked the SC and it looks like fuser rotation percentage is at 107%, so it was rotations that caused the call. Now I've got to figure out how to stop it, so we can rely on pm counts to flag up only.

The rotation count and % are actually PM counters. Apparently @remote only picks up page counts. To turn off the display, check the settings of SP 5062. If any of them are set to 1, it will display that unit needs to be replaced when either page or rotation reach the recommended PM count. Ricoh put out a Facts bulletin on PM counters a number of years ago.

That's what I get for not checking MY-Ricoh. although I doubt I'd of found the facts sheet with it's horrible search tool.

Thanks very much, problem solved.
