Need Help Mutoh 1324 shuts off before initilizing

    I have been trying to fix problems on my Mutoh 1324 that all started with some clogged nozzles. I am a teacher, and I have a school-based business where students manage and perform all operations. Since this is a real-world learning experience for them, we do not make enough money to afford to bring out a service technician. So I am doing the work myself while knowing nothing about this machine. However, I am learning a lot! I do a lot of research before taking anything apart. I have made mistakes and have had to replace some things to make up for it.

    The last time I turned my printer off was when I was taking the dampers out to decide if I needed 4 new ones or not (because I ruined 1 or more of them when I was trying something else). Anyways, I finally received and replaced the dampers today.

    Then I decided to make sure that the capping station was saturated before putting the head back. The solvent would not soak into the capping station. So I assumed there was a clog somewhere in the lines below. I tested piece by piece until I got to the point where I could not push solvent through easily (just before the motor). I used a little more pressure, tried squeezing the lines coming out of the motor, and eventually I was able to get the solvent to run through the motor. During the process, however, some of the solvent would come out from the seal between the syringe and the lines and drip. I do not see any elecontrics that it could have dripped on, but again, I know nothing.

    I get the printhead carriage back together, and I cannot get the printer to stay on. When I turn it on, the display turns on and shows the model name/number and software version. Then it clicks off just before it starts to initialize. Did I cause a short somewhere?

    Related or unrelated - my wiper won't pop back into place when I manually push it back.

    Any help you can provide would be wonderful! I cannot get a tech out here. There are none that I can find nearby, so we would end up paying a lot of money just to get someone to travel here.

    The power supply is "crowbar"ing. Meaning it's shutting off due to excessive current load or a short. Likely that you got ink or cleaning solution in some electronics. It may recover if you unplug it for an hour or two.

    I agree with SsignatureSsignature but it's really rare for something to short in the maintenance area. I would unlock the head and push it all the way to the left of the machine and then turn the machine on and see what happens. Also, unplugging and waiting for a while could help as well.

    Thank you both for your replies.

    Ok I have moved the head to the left, let the machine sit, unplugged, for a couple of hours, and I still have the same result. Other ideas?

    What’s happening is that the power supply or the main board is failing initialization. It could be an ink spill - but I’ve seen many running with ink covered main boards. It could be some other sort of short, or a main board failure. About all you can do at this stage is wait some more with it unplugged. If it were a problem in the maintenance station causing the carriage to not release , you’d get a CR Overload error, not a shut down.

    You could try unplugging the maintenance station and powering on. If it is the station causing the issue the machine should turn on and give you an error. If ti still shuts down, you could have main board damage.

    How do I access the main board? Is there anything I can do to check and see if there is a short? Or can I do something to help dry it out faster (if that's the case)?
