It is obviously more complicated than I initially thought. The bearing itself is housed in a plastic bracket of some kind, which is different for both sides, - I assume, that these have to be removed first, before the bearing itself can be removed (? Please, prove me wrong!), and for this, the...

I could need some assistance here - do you know a non destructive way to remove the bearing from the PCU housing? I don't mean the element securing the developer roller, which is obvious. I mean the bearing itself. There seem to be four metal latches every 90 degrees around the bearing - does it...

For the case someone else needs this information, the bearing on this particular magenta PCU developer roller is NTN 6800LU, as far as I can tell without the magnification glass. https://bearingfinder.ntnamericas.com/item/deep-groove-ball-bearings/single-row-radial-ball-bearings/6800lu

One more update: I further examined the magenta PCU, and now I can exactly see the problem (at least on this PCU, assume similar/same thing on the black one). I attach a video... The bearing on the left side (front) is loose to an extend of 1mm I would say. The right/rear one does not have this...

I wonder if there is any way to diagnose if this could be the drive? I could maybe switch the drives between black and 5th Station which we are not using often anyway (would need to check in parts catalog if they are the same). But as I have the broken magenta PCU showing obvious malfunction...

I looked today at the used magenta photoconductor unit that we got with the machine, which obviously has been changed as the machine still had the contract (we even got TWO used magenta PCUs - was obviously a more severe issue there). It has a pattern that looks similar to our issue with black...

It is the same - you have the unit with roller and cleaner, - it only takes seconds to change it, as it is on top of the whole photoconductor unit.

Hi, we already changed the charge roller. No change. Today I also changed the cleaning unit, - thought this could be some kind of vibration there, but also no change. So what is left, is developer unit.

Hi Greg! Thank you for your reply! I think you are 100% right on this - and yes, the lines are stronger to the front of the machine as to the back, - the issue with the C7100 is, that you have to replace the whole thing - it is called photoconductor unit - and includes the developer group (I...

Hi Guys, we have a used C7100x, - I have a banding pattern in Black, which I initialy believed, is could be developer related - 50mm, 25mm pattern. - but I am not sure anymore, ... I attach a foto. A single pattern is ca. 17,5-18mm (ca. 0.7in) wide, - two ca 35mm (1.38in), - three ca...

Thank you msaeger for your prompt answer. Do you know what settings are realistic? How low can we go? We dont want to generate new issues (like when the unfixed toner gets stuck somewhere in the printer) by setting it too low. Right now, the setting is ca. 168 degree Celcius (ca. 334 F) for the...

Hi guys, we recently added a (used) Ricoh C7100x to our printshop - the most laser printers we have are from Canon (the newest one being C9280 with Fiery GX400), but we badly needed something more modern, and the Ricoh seems to be a good choice - we do not regret the purchase. Now, I have to...
