MP4/5000 updte/feedback

[E Winter]

I'd just like to hear back from you lot how you're getting on with these bastards. Since the last tsb and a couple of dev changes our machines seem to be runnig ok in general. Any feedback is welcome -thanks in advance.

We're still dealing with the same problems. Light image density, coated mag rollers - almost no difference compared to the old stuff.

And I agree - high volume seems to force the problems earlier, probably becsue of the higher temperature levels inside the dv unit. But I can't tell my customers that this machine isn't made for using it inside the specification targets - especially if the customers already worked with the previous models (NAD, Adonis etc..).

Mississippi is so poor to begin with, we haven't noticed the recession nearly as much as everyone else.

we've been monitoring one of these models from the start of the problem did the dev/toner change 80k and again at 150k with the rest of the pm items, been sending one dedicated engineer to this m/c, but now solids are going lite checked for relevant sc codes none do forced toner checked drum gnd td values vsg vsp all look within spec only to notice the mag roller is contaminated contact our ricoh head office to be told by the product specialist because of the previous problem techs have worn off the layer on the mag roller from cleaning it to solve the problem order new dev unit our account !!! unfortunately their goes the profit made if any, it seems we are the prototype guinea pigs, something wrong here!!!

For us the part replacement and even entire dev unit was not a problem until the recession start, but was no improvement. This was the reason I said either some units are built in a Friday night during a massive drinking event at the plant, either the QC is sleeping sometimes.
Last week I had a call for a 4500 with really light copies. Dev life was 80K, mag roller was completely coated, so I replaced with the new one. REplaced the dev and a completely new PCU unit. Customer just received the new toner type so I readjusted the SP modes involved to their default values as the TB advices. In 5 days customer called back now for background and blotches on pages.
Honest, I never saw a machine overtoning so bad. In the PCU was 3-400 g of toner, cleaning blade was crap. Re dev it and modified back the SP to the values recommended for overtoning. Good part....the new mag roller has no coating on it...so the treatment is improved
