    Ricoh 651 / 751 experience

    Is anyone here running a Ricoh 651 or 751?

    The announced 1200 x 4800 dpi of the c651ex and c751ex sounds sharp. How does the 651/751 series stack up to the 901 in production and registration?

    I'm actually wondering the same thing.. I'm looking into this product and cannot find any reviews on this. Have you since found out any more information?

    FLPNYC,

    1. What is the Color like on the machine?

    2. How frequent do you have to make service calls?

    3. Are there jamming issues?

    4. What is the thickest stock you have gotten through the machine?

    5. Are you happy with the registration? What about when you duplex?

    6. How does it compare with other machines in your shop?

    7. Would you rather be running a different brand or model?

    8. Are your customers happy with the quality of the prints?

    9. Do you like the TCRU's (Trained Customer Replaceable Parts)?

    I am currently trying to decide between the Konica Minolta c7000 and this model.

    Thanks

    FLPNYC,

    1. What is the Color like on the machine?
    I could not be happier. With any machine, the equation is. Garbage in = Garbage out.
    2. How frequent do you have to make service calls?
    I do about 30-40k per month. It's been over a month.
    3. Are there jamming issues?
    You only get jamming issues if you do not profile your papers. Actual paper weight conflicts with Print file setting.
    4. What is the thickest stock you have gotten through the machine?
    130 lb dull matte. 350gsm
    5. Are you happy with the registration? What about when you duplex?
    Registration is PERFECT... Duplexing is amazing. Its been spot on since I got it 300k impressions ago.
    6. How does it compare with other machines in your shop?
    The only other Machine I have in the shop is a cpp660. I only keep this machine around for printing on specialty papers. Thick, non-white, un-smooth sheets.
    7. Would you rather be running a different brand or model?
    I have looked at all the equivalent products out there and nothing compared for the price and quality.
    8. Are your customers happy with the quality of the prints?
    We do a lot for the fashion Industry. I have yet to receive a complaint on the quality of the prints.
    9. Do you like the TCRU's (Trained Customer Replaceable Parts)?
    Absolutely LOVE them. I switch out Fusing units depending on the size of the paper in under 1 minute. Anything small goes wrong, I don't have to wait for a tech to come and do something the I was fully capable of doing. i.e. removing 3 screws and swapping in a new part.

    I am currently trying to decide between the Konica Minolta c7000 and this model.

    You can get a New c751 for the price of a used c7000. It really is up to you.

    Thanks

    Ricoh C751 Update NOT GOOD!!!

    Beware, we have purchased a C751 from IKON and the 40,000 clicks were amazing. After the 40K, we have been experiencing serious banding issues and the techs are telling us that ALL of the Ricoh units are doing it and they do NOT have a fix for it. Luck for us - Ricoh sent the check back to us by mistake and now they haven't been paid for the machine. They are working FRANTICALLY to fix the problem, but do not have a solution. We have been told that if they replace the unit the new one is going to do the same thing. The banding is in the form of roller patterns and is much more noticeable in screens and solids. Grayscale is the worst, but all units do it singularly. They have literally torn our machine down and reassembled it to no solution. We are told that Japan is aware and that the prints are "within spec." There is NO way that a Japanese engineer would look at these prints and say they are within spec. The banding issue is so bad I have had several jobs rejected from customers and the quality of the prints are mostly unacceptable. It looks like it came off of an offset press with bad rollers. They are selling this as a production press/unit. They are selling it at both ondemand and the Chicago printing show. It is far from a production unit! Jamming issues - YES - the machine hates offset stock. registration is better than some but not perfect. Still has room to be better. Coated stocks look nice, but all stocks are subject to the ugly banding. Beware of this unit and Ricoh unless they come up with a fix for it and if you know of one that would be awesome. The machine has potential. They are trying to fix it, but they do not have a solution for it. Right now we have 300K on the machine and the banding is atrocious. If you have questions PLEASE ask.

    This is not good.

    We just ordered the c651ex.

    Is anyone experiencing this with the slower model?

    Unfortunately, nothing concrete yet. Thus far we have been into the unit of almost 4 months now and we have been experiencing far worse problems than just the banding issue. To answer your question about the banding more specifically, the techs have tightened some screws to the drum motors and that took anywhere from 60% to 40%(area dependent), of the banding, but it is still really not a salable sheet on about a 20-30% screen. The banding doesn't show on jobs with full color images as bad, because the images hide the banding, but when you run jobs with screens it is pretty awful. Not salable to our customers anyway, we've lost a slew of customers of the downtime too. Right now our machine is approaching 300K or there about, and it has had roughly 75% downtime over the last 4-6 weeks due to to drum code related errors and each time they fix the problems - it cuts out again within 1000 sheets or so on average for the same errors. Another ongoing issue we have been experiencing with this machine is the size 8.5X11 sheet printing from all of the bypass large capacity trays - these trays feed the sheet into the machine, but will not get past a sensor in the engine. This has been an issue we have had since the first week we owned it and it still isn't resolved. They thought it was fixed on 3 separate occasions, with three different fixes and it comes right back. I would love to hear feedback on other units out there of the same model. They are telling us that 300K in 4 months is the top end for running this machine, but I can't see that considering it has a 350K 8.5X11 duty cycle and 180K monthly volume cut 180K on half (mostly 75% of what we are running is 11X17 or larger), and that should give us about 90K per month 8.5X11 that we should be getting out of it...well we aren't getting that. I will keep you posted as it develops and if they're able to get it fixed. It would be nice to have it running smooth, because when it prints - it prints nice color. The banding is an issue and with the amount of downtime - it is a HUGE issue. What would you do if you were experiencing this amount of downtime in your first 3-4 months and it started just before month number two?
