  • Oce Arizona 250GT Frequent Printhead Failure

    Dear All,

    I looking for potential buyer for Oce Arizona 250GT, UV Inkjet technology with variable dot 8 picolitre.

    I am having Oce Arizona 250GT for sale with well maintain and running condition.

    This printer can print flat bed rigid material 4x8ft or roll to roll (unattended Print running more than 12 hours non-stop). Very ink saving and easy maintenance. Just ink filter, top up coolant, cleaning dust at table and dust filter.


    Thank You
    Frankie Koh

    Hi Frankie,

    Something is definitely wrong. Oce printhead should last 3-4 years under typical (12 hrs per day) operation.

    Are you using OEM inks? I see frequent nozzle clogging problems with our clients when they change to bulk ink systems.

    But... I think your nozzle clogging is a symptom of another issue -- microparticles of dirt in the ink carrying system. So, even when you add new ink or do your syringe cleaning, you're not really solving the problem. The nozzles just re-clog.

    I think your best solution is to (hope you're sitting down) clean the entire ink carrying system.

    The weird thing I don't understand is why they would clog next to each other? Unless they are clogging because of the drying element? Just a thought...

      more info

      More info Please:

      How long each day do you print ?
      How Long idle ?
      Is the machine on when Idle ( overnight ) or is it powered down ?
      How often do you change filters ?
      When Idle does ink drip from heads ?
      Head Height is correct ? too low can cause strikes and or clogs.

      What material do you print on. IS it generating static.
      Roll or flatbed material ?

          Really sounds bad for your service guy, escalate to upper management since those head lasted two years of almost 24/7 printing here. Could be a coolant or electrical problem, baring any user caused issues.

            Hi

            First of all daily and weekly maintenance is crucial for printhead reliability.
            But is you printer located near solvent printer?
            It is a well known problem that if the Arizona / aquity printers are located in either a dirty enviroment or near a solvent printer you will get permanent nozzles out in groups.
            Another thing you should pay attention to is to make sure you don't drown the heads in flush.
            The flush NEVER get inside the printhead as it will dissolve the electronics in the head.
            So flush only on the nozzle plate ( and please - no syringes )

              I guess I'll never complain about our vutek heads. 21 heads in printer (UV). Replaced 9 in the last 5 years. The printer runs 9 hours a day.

                Yeah small printers tend to be more fragile but that all depends on the workload, conditions ( not near a solvent printer, dust, static etc), and the operator, to some extent the field eng too.
                Vuteks tend to be of heavier metal , beafy with rugged parts, but the average is 2-4 per year per machine ( all under either an ink agreement ( 2 per machine per year free ) or service agreement ( 1 per color per machine per year RE FREE.) in our case thats up to 6 and 8 time the number of machines, Contracts are expensive but we more than make up the differance at almost 24/5 and 24/7 production. I do the service so mostly its for parts.
                Vutek head problems are mostly crossfiring ( even after flushes ) and some heater failures either stuck on or off. You will get one day a shorted head which is nothing but a pain because it tends to cascade into multiple board problems.
                GAndi/agfa is almost always cloggs but you will get a short hear and there. ( not very expensive but cheaper (50% off ) with ink agreement
                Oce/fuji will clogg or just fail badly and are expensive.

                Uv printers tend to be more problematic for a number of reasons:
                Uv light reflectins back to the head and cureing ink on head,
                Head from uv light
                Material strikes because of head or poor vac. table
                static from material shocking heads
                dust attraction. etc

                  Vutek service agreement is very $$$$. We have never had one. The guy that runs our press could work for them. We get hour head replacement thru Nazdar and the ink volume we buy.

                    You got that right very pricey indeed,
                    The issue is arizona printhead failures. so what environment the printer is in is important, static is a big one, and what materials printed are used, of course head stikes are deadly.

                      We have been very fortunate with head strikes. Don't get me wrong we have had 3-4 dozen but the strike has never taken out a head. We even had a few on .024 Alum. Turned the sheet into a pretzel but the heads were OK

                        Most often, frequent failures with the printhead are caused by static on the media. What kind of media are you printing on most frequently? Are you seeing printing defects? If so what kinds?

                          Oce Arizona 500

                          We have had the Oce Arizona 500 for the past 20 months and already we have had 3 printheads go. We pay £1100 every month for maintenance, and today the engineer was called in AGAIN as the machine was not working properly, he then told us we have to buy another head and pay £5000 for ONE HEAD !!!
                          The head failure was not our fault and seems to be a fault of the electrical system within the machine as the engineer suggested, but Oce are saying we must pay for it. When we complained to Oce, they basically told us to pay up or shut up!!
                          Who can afford to pay for printheads going wrong every few months? I will not recommend this machine to anyone again and will never buy another Oce product again.
                          Regards

                            We you say they go ( fail ) are you talking about complete failure or just blockage ? I have found that even machines under so called contract have ink filter that are way overdue for changing. If you are talking about nozzle clogging there are ways to solve it without changing or removing the head. Send me or post a photo of your jet test.

                              Tell Oce thank you very much and goodbye, will be looking at a replacement for the 500 and it WILL NOT be an Oce product. I don't think I've every met one happy Arizona customer. I've known 5 companies who ran they and they all had major issues. Do you self a huge favor and start looking for another printer if you have not already
