Definitely not the motherboard. Test to see if the capping sealing is good and the vacuum doesn't pull air. Replace the capping with a good quality one, test the vacuum then run a normal clean. If all good then do a nozzles wash for 15 minutes then run a new clean to see if there is any...

Yes, I did buy from Digiprint Supplies and I was very happy with them. Usually I replace the capping every six months even if they are still keeping a good seal. In terms of quality I can't see any difference between the generic and original. Not the same thing I can say about the capping...

It looks like your capping does not seal properly. Disconnect the vacuum pump, connect a syringe and pull some ink after you open all ink valves from service menu. If the ink is coming with bubbles or not at all, then you have a sealing issue. Change the capping with a brand new one. The OEM...

To install a new capping takes five minutes. Have a look at this video: Just soaking the printhead will not solve the nozzles blockage. Replace the capping. It is also recommended to do a capping position adjustment if you use a different brand or capping shape. To save your time and ink, it is...

I had same issue with two brand new capping. The third one was good. I always keep a 3-5 pieces as spare. It is a lottery.

Underneath there are the vacuum fans. Probably one of the fans has problems with the ball-bearings or dust. Without seeing or hearing it is hard to tell.

Get the service manual and find the meaning of these errors. I tried to find your codes in my service manuals for a CJV300 but no luck. Probably the UCJV has different or extra error codes. I did fix a couple of Mimaki boards and power supplies just by replacing a few busted transistors or...

Looks like the capping station does not seal and the vacuum pump pulls air. Next offender can be the vacuum pump but at this model the pump is very reliable as I know. To test the capping sealing, disconnect the vacuum tube from the vacuum pump and connect it to a syringe. Put the printer in...

Check first the cyan damper what Zoogee suggested. If you have ink inside the damper then check the capping. Most of the times when you loose a channel is the capping. Your print test looks like a Mimaki CJV150/CJV300. Mimaki's capping is notorious for the poor sealing, that is why I replace the...

To me looks like you have two issues. First is a nozzle deflection on black ink. This happened to me with ES3 ink everytime. Always the ES3 black ink did nozzle deflection after a while even on brand new printheads. Second, indeed, looks like you need a drop position correction. Do this first...

I had a similar issue with my Mimaki and ended up being bad quality capping. Your head cleaning is not working as it should. If your issue is the capping station then during head cleaning process just the nozzle spray is working and the vacuum pump cannot pull the clogged ink from the nozzles...

The mystery has been resolved. I found dried ink on the bottom of the wiper moving assembly. The wiper holder did not click while inserted leaving the wiper one-two millimeter higher that it should be. This created that slingshot effect splashing the ink everywhere during the cleaning phase...

Thanks. I will check again the wiper holder. Now that you say this, I will check the height of the wiper. Looks to me bit too high and that can explain the slingshot behaviour. Normally I keep the capping station very clean and I don't allow ink build ups. Thanks for the tip.

Sorry, I had to keep my thread short and I did not explain why the capping station looks like that. The solvent showed in the capping is to prevent drying. The pump and the tubes are filled with cleaning liquid until printhead installation. When unclamping the tubes, the cleaning liquid drains...

I bought a second hand Mimaki CJV150-160BS almost new with a fried motherboard that I fixed. The printer came with a lot of disassembled parts, all in a cardboard box and I am not sure if I did get them all. When the printhead gets cleaned the rubber squeegee splashes ink everywhere around the...
