With all the hype on this bad boy what is the length of time for a pm on this machine ?

Officially the first items are 150K, but it will probably need charge rollers every 30k.73 DE W5SSJ -
PM TIME
How long does a 150k pm takeComment

Not sure, to be honest. The failure rate on the PCU's has been so high for Charge Roller lines and developer problems that I've never gotten to do a complete PM on one. I figure about 3 hours, but that's only a guess. If you're familiar with the previous generation machine figure each PCU will take you twice as long, and pray you don't have too many problems loading and initializing developer.73 DE W5SSJComment

MPC7500 PM
I too have yet to see one go the distance. I've been too busy replacing charge rollers every 15K to 20K. The last time I got called for the line issue I ended up removing the drum, charge roller and developer and vacuuming all the clean station. The lub bar seems to self destruct! I used glass cleaner on the charge roller. I managed to get by without replacing the charge roller so far but it's only been about 10K since the cleaning. The last model did better on PMs and was a lot easier to take apart!!Comment

the time it takes me to do a 150k pm is about 4 hours with vacuuming and developer change and a 300k takes about 6 hours with 150k pm included.Get your facts first, and then you can distort them as much as you please.Comment

This seems to be putting PM time at 50% over the B132/B200 series machines. It seems a lot of the new Ricoh equipment has gone to more time consuming preventative maintenance. Some of the fusers seem to have been put together as an afterthought. I have yet to see on of the D014/D015 coat the drums like I was getting with the B132/B200 series but time may tell. Anyone had this problem?Comment

Coated or scuffed drums were probably one of the biggest causes of uneven density on the old machines, but the machine was usually at or over PM anyway.
Not that it was as big a deal - the PM was so much faster (especially since I was used to working on the 1350's with a PM every 80k developments or 20k pages) I'm really really really not happy with the "upgrades" in the MP7500 and I've been pushing my salespeople to stick with an MPC5000 (or 2 of them) if they can't bump them up to a C900. Sales listens like they always do - even though I've started comparing this evil box with the 1224c which they remember as costing them quite a few customer loyalty sales. It's like herding cats.73 DE W5SSJComment

I've had the 5560c series go way over PM without much of an issue. For a while though it seems there was a bad batch of lub bars cause with 30 to 40K of PM suddenly a machine would coat the drum. I've had lub bars come apart in new MPC7500 and take out blades and drums. We always end up hearing the issue of the air here being the problem. Nothing beter than a machine running at 10% or less humidity on top of the lack of pressure a mile up. Oh well, live and learn!!Comment

I've got the opposite problem - long hot summers with 90% humidity. The HVAC guys have it worse - imagine having to work someplace in weather like this when the only reason they ever call you because the A/C was out. They have real problems installing the right unit out here - a system that is big enough to handle the heat in mid summer is usually too big in spring and fall, so it doesn't run long enough to pull the humidity out of the air. Seen brand new buildings stink of mildew - does wonders for copy machines. Every install on my machines the damp heaters get hooked up, its just not an option to leave them off.
On the plus side I guess is my 3260's run great. I have the known issues with them: Unstable toner density on long runs, Transfer Roller scratches, Peeling Hot rollers at half PM or less - but I'm not cleaning charge rollers every 20k or futzing with the developer trying to get it to initialize properly. I can deal with that stuff, and I can do a really good PM on one in 3 hours, instead of a rushed, crappy, just glad I got it working again job on an MP7500 in 6.73 DE W5SSJComment

I don't miss the 90%. I grew up in Kentucky and got enough of that weather to last forever. We do run into the occasional account that uses a swamp cooler. They make nice spots due to wet paper! On a lot of Ricoh printers we were able to adjust transfer voltage to fix quality issues. It isn't so easy on the 7500 or the 3260c machines. I have been lucky in that the 3260c seems to run from PM to PM without much effort. Too bad the 7500 doesn't carry that ability on!Comment

I did a recently a partial 300 K PM on a machine with 245K on black and just 5700 prints in color. From one PM to another I'm trying to improve me speed performances without cutting on quality of my work.
So, it took me 90 min to PM the K unit for 300K, replace the developer, replace all PTR parts and oil roller and cleaning roller in the fusing unit, clean the working area and pack all the garbage.
Due to the extensive vacuuming required and the increased number of customers pissed off by the terrible noise I think a better idea is to have already with you a set of units already rebuilt in the shop.Comment

Can anybody tell if other manufacturers like Konica Minolta or Xerox for this mid-high range of color machines use units or individual parts to perform the PM?
Even Ricoh MPC 6000 & PRO series are asking for PCU units....this message is popin up after 200 K "Please replace PCU "K or CMY" unit. So what's the point of a message like this if we are going with 2 huge boxes (150 K + 300K PM kits) with over 60 individual parts in them to the customers...????
Many of them as soon as they hear that the maintenance will take over 4 hours for 300K get really upset and are calling managers and sales people to complain.
The cost for Ricoh units it's huge (~500$/unit + 200$ bag of dev) and the cost for both PM kit's is ~ 225$/kit so 450$ for both.Comment
