MP4/5000 updte/feedback

[Voltage]

I have a SP8200 which i think are the same as the MP4000 without the scanner. Mine has got 750k on a.t.m. I have only been there 5 times. 4 of them PM's. Work 100% better than the 8100 they had before

I'm consequent and stick with the same idea since the first problems with 4-5000 started.
It all depends on how the users use and abuse these poor machines....
I have plenty of 4/5000 with the genuine (first release) dev units + old type toner that are performing well....but the customers are at 10K/month with a decent page coverage (where they should be all)
and
I have plenty of 5000's with all the mods done: new dev unit + new toner and still after 40K the quality is crap, black is faded and dev is weak but they are running over 30K a month...
So who's with me on this one???

I've had Lanier 5645's run 80k a month with no problems, so no I'm not with you - Ricoh should fix the damn toner. Period.

I've definately jinxed myself posting this, we had another one come in today with grey background. I vacd out the pcdu, scrubbed the mag roller(new type dev unit) cleaned the transfer section-worked a treat. Until 4pm this afternoon. New dev and new type toner went into it 22k ago. I'm syuck now cos I cant change any parts.

Yeah I'm with you. I have a bunch of these and the customer actually listened when they were told what volume they should be running so they have not been having issues. They mostly have old dev unit, and old toner.

When I get a CQ call I have been rebuilding the PCDU with a new dev unit.

If they want to make 80k a month they should not be buying a 35ppm machine. The customers I had with the old B082's that made that many copies called all the time too.

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.

[ADRIANL]

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
