We just got our 7210 installed at the end of March. So far it has been a champ compared to the KM machine it replaced, no service calls yet. What sort of image quality issues do you have?
Ok I'll take a stab at it.
1. The operator training was woefully inadequate. We ended up asking and getting additional training SPECIFICALLY so that we could maintain the machine with 'user replaceable' parts.
2. The press interface software is buggy and inconsistent causing much grief. For example when we change paper spec at the 'tray' interface, go to Fiery to print, the press errors. You MUST replace the paper to a different spec in Fiery, then re-add to get back to the paper specced. In other words the press doesn't update the spec at the Fiery even though you specifically made the update. You could try to fault the Fiery but this is just one example of the Press not communicating to the Fiery (our Xerox's have no such problem.)
3. Once we started doing 'self service' on user replaceable and CLEANABLE components we noticed the basic settings on the press use the 'least' amount of material. In other words the density of toner during runs, the cleaning of drums, the cleaning of the fuser, are all set to the minimum available. Great to keep the supply usage down but not so great when you face density or other quality issues that don't have explanations or examples.
4. Yes - we have gotten much better at diagnosing and treating quality issues. But I think that most of the issues could be resolved with dedicated maintenance. The first ~ six months were good. The next six months a nightmare of downtime while waiting for service to fix this, replace that, etc. (when they could figure out what the problem was and got the right parts)
5. And I won't talk about the service. Period. Doctor says bad for my blood pressure.
6. And then the kicker - the toner density on jobs CHANGED during runs. I know, you say 'hey, it's self adjusting.'
Well, except that the color can change dramatically. We have had MULTIPLE instances where we went from good to bad, and not just a small amount of change. If one of my operators had come to me and said 'hey, the color changed unacceptably while I was running' I would have been very skeptical. But I was the one who watched it happen while the operator was on a break. Sigh. We had a Ricoh engineer here who stated emphatically 'that can't happen.' So we proceeded to show him the multiple examples. They finally determined that it probably had something to do with the fifth color unit which we weren't using. And in the exploration they said 'hey - the machine is running SERVICE MODE self correction routine that is failing because the fifth color is off.' Ok, they said if we turn on the fifth unit it will self adjust. It didn't when we turned it on. But that gave us the info we needed to understand the issue well enough to mostly work around it.
We perform a density calibration before any proof or run. That helps stabilize it. And heaven forbid you turn the machine off or on and expect the same results.
Needless to say the operators are gun shy.
So right now the fifth unit is turned off in the service menu and it usually passes the calibration test. Not always.
And Ricoh said that it will work as intended with the fifth unit on IF we keep toner in the fifth unit. Hmmmm.
This leads back to the issue where we left the fifth color toner out of the machine because we have to pay ~$500 per cartridge and we noticed that just being in the machine it was getting used up when no job used the toner. We were weighing the cartridges to determine job costs. Ricoh verified it uses a 'small' amount (for us 1 toner cartridge in the first 2 months of non-use) in the COLOR CALIBRATION routine.
So the final decision was we told Ricoh - turn off the fifth unit completely and we have to live with the color inconsistencies OR provide us free toners so it self adjusts the way they say it is supposed to behave.
You can guess their response.
We got no free toner so we turn it off.
But we still face random changing color issues.
Sigh.
