    classycars, my 751 was installed in Dec, 2011 and I echo, literally almost verbatim, your two threads. Since your last post, has anything changed for you?

    Well, we still haven't had the banding resolved. Registration issue comes and goes. They can generally fix it, but it is extremely annoying and too frequrent. The Fiery on the front end has an issue where we cannot lineup the duplexing from files sent from a MAC, but it works from a PC. We have had over 230 machine instituted service calls in a four month time frame for the exact same types of issues, NOT including service calls we have made or the machine has made for OTHER issues. We have experinced a great deal of down time on time on the mahine as well as a loss of customers from it. We were regularly doing work for an instituition in NYC and the work was pulled from us when we couldn't deliver 100 color copies printed on a 100# gloss text stock. We were doing a great deal of their work on this machine and now they went elsewhere becase we couldn't deliver. We have since taken a significant amount of the workload off of the machine and put it into the press room, at added expense of course, in order to meet quality and deadlines of customers. We are still in the same boat basically and we don't have answers to the quality issues. The downtime is inexcusable.

    I would definitely get a different machine. I wish my customers were as loyal as you've been to Ricoh.

    What does the banding look like, can you post a sample?

    Attached is a picture of our current banding issue. Within specification? I will let you decide. I would love to get another machine, the problem is that they will not take this one out and I am only 6 months now into the contract with them. They claim it is working within specification and we are putting more clicks on it then it can handle and we are using stocks it isn't rated for - neither of which are further from the truth. We hardly run a cover stock and when we do the stock we run is below the rating for the machine. We are also a great deal below the rating as per the number of clicks the machine is supposed to handle. Click the link to take you to the full sized image.

    Do you have the CED with the volumes listed you said you would run and they agreed to? I would push this to the top and fast, your amount of calls and issues in a 6 month period is beyond excessive and if you are indeed not beyond the scope of the engine then I would demand a 901GA at the same price installed now.
    Get in touch with the owner of the company and tell him you want him/her, the Service Manager and the Ricoh Dealer rep on site and lay out everything. You have been patient and worked with them to resolve things, now is the time to get results from them.

    Fairly confident I know the problem...but not 100%

    Your machine is printing problematic of some office grade machines I've fixed before. A few questions and then my thoughts...

    1. Is that a black only print out or a composite CMYK "black" print out. If it's black only it should be pretty much pitch black unless the scan made it lighter.

    2. Is the band printing horizontal or perpendicular to the drum? In other words if you do an 8.5x11 print with the 11" edge coming out first, and the bands are running from top to bottom all 11 inches, it would be horizontal to the drum.

    First, I'm not a ricoh production tech, but the mechanics are the same and I have solved similar problems on other makes and models; but my suggestions might NOT be the answer to the problems. So I'd follow up on my suggestions, and especially if the service log or the tech hasn't tried something, I'd try it...

    So...

    Initially, I'm thinking it's a developer issue. It can be anything from replacing a developing unit, corona/webs, to poor contacts between the machine and the developer unit, to even lumps of toner being caked on the developers mag roller (roller that charges the developer carrying the toner to the drum). It could be a drum/blade issue or a false drum/blade issue if it's the mag roller. It is also possible to have a fuser related issue causing this.

    What you can do to help narrow the problem down:

    1. Send a couple of prints (it would be helpful if you can isolate the colors by sending a solid block printing black, then cyan, magenta, then yellow). I'd send about 20-30 let a few exit the machine then open the door or whatever you need to do for force jam the machine with papers at various stages within the machine.

    2. Then what you do is follow the paper path and clear the pieces of paper until you get to the first point where the bands are. This is the easiest way to isolate the area of the problem. e.g., if they start at the drum it's a drum or developer issue, if it starts at the fuser, a fuser issue.

    If you have a copy option you could test making analog copies to see if it's a print only problem. It is theoretically possible to be a dirty laser/mirror, memory, or firmware issue.

    If I were the tech, I would do what I mentioned but also:

    1. Use a voltmeter to verify power readings from the wall to the machine and from the connectors to the developer units.
    2. Check the power settings and voltage to the drums, coronas/webs, and lasers (their power is adjustable).

    Right now most likely fix is putting new developer units in.

    Other considerations, I have had problems before with too old toner and developer causing such issues but this is too new to be the issue.

    I kind of feel it's something more complex or a design flaw since the problem is so universal to many machines. Because I'd hope that a good Ricoh tech would have already done the things I mentioned. Something in design or from the factory could be the issue and if so...it may be outside of my comprehension.

    Good luck and please keep me posted. I'll try to help if I can.

    Oh btw, the sample is not within spec. Even on an office grade machine with a "lower standard" I wouldn't find it acceptable; but I'm pretty picky.

    If all else fails, just stop payment, get a new machine and tell them they have five business days to pick up their POS. If they dare sue you, which they probably won't; I'm quite confident that you'd win. Plus let them pay for the filing fees and pursue you then you can counter-sue for free.

    It's not the Developer Unit!

    I am having banding problems, too, (among other things) and my machine has had every part replaced in it including the developer unit, the rollers, the transfer belt and several sensors. The latest "fix" to the banding problem was to remove some gears within the rollers because it was thought the gears were causing the rollers to pulsate. The tech was at my center for 4 hours yesterday and, well, I'll let you be the judge if RICOH's "solution" worked or not.

    Well it's still likely that it's in the charge and develop process...unfortunately there's a thousand things it could be...

    toner supply
    developer
    drum
    dozens of rollers or sensors or gears
    laser units
    charges to any of a number of areas
    and incorrect temperatures and charges to different areas
    bad hard drives and firmware

    Actually now that I think about it, even the print drivers can cause these problem...a bad driver or bad version postscript or pcl...

    Best bet is to have them take it back on a recall and get something else.

    Easier said than done. I've tried numerous times. They have yet to acknowledge the issue as something more than "a new machine working the kinks out of itself." It's been over 6 months and the "kinks" are getting worse, not better!!!
