What sort of things is the customer printing and onto what sort of paper?

standard printing on plain paper

Re: MP-C3503 poor fusing

standard printing on plain paper

is there an envelope setting?
does this have a "gap" procedure on the fuser?
generic toner?
what type WEIGHT settings for print driver?

+1 on the generic toner. I had a C4503 service call today that's going to have a premature fuser unit failure due to generic toner. They're at 280K and the fusers are rated for 400K..... but they'll be lucky to get 325K out of it.

Well.. my 1st thought also.. I do remember some had a 'gap' adjust on the fuser rollers..
Yup.. gen-shit toner SHOULD always be 1st suspect

Hi there!
My fellow tech had a similar Problem last week,looks like poor fixing, but only with black color was OK. Changing the fuser doesn't matters. The solution was changing the whole black PCDU. The machine has 130K copies and genuine toner.

Machines with sleeve belt fusers don't have adjustment or envelope levers. They always use the same pressure.

HUH? the fusers always adjust heat/gap for paper weights. may not be mechanical adjust .. might have levers inside that open close via print command.

Most color models have a pressure lease system so the the pressure roller is not left against the fusing film when not making copies. For the CXX03 line the gear on the fusing unit that actuates the release is AB012099 GEAR:ON-OFF:PRESSURE ROLLER. This is the Gear A that needs to be removed in order to remove the Fusing Rear Cover. There is a sensor flag at the front end that indicates whether the pressure roller in On or OFF.

So Slim.. on this model there are pressure relief * either lever or "auto"?
I didn't think my theory on various brands was that off!
Not always up to latest tech... but hell theory have to come into play.
Thanks for reaffirmation!

You're right, the color machines do have that. I must have been thinking of the BW machines which don't.

I was incorrect earlier. Yes on color machines there is a gear controlled system to allow the machine to adjust pressure. I was thinking of the BW machines with sleeve fusers the xx54 and xx55 which use a fixed pressure. On those models the only time pressure is released is if the right door is opened.

Worth noting that the upper limit for plain paper on these machines is 60-81 g/m2, 16-21.6lb We have a number of clients who use 90gsm as their default stock and it's a pain on Ricoh kit. You can often use 'tray switching' and 'extended auto tray switching' to get around paper tray mismatch printing errors but you need to test these settings in the clients environment. You can, for example, set a paper tray to 'middle thick' (which slows the copier a little but extends the stock weight to 105gsm which will fuse most stocks) and have the machine ignore the mismatch by either printing from the specified tray regardless of type or ignoring the specified tray and selecting one with plain paper. Works well if you specify which trays can/can't be included in auto paper selection.
