UJF-6042 MKII Error 533

Roll your clock back if chips are expired under the #ADJUST menu. Take your flush and fill each bottle tank to the lower inner lip where the bottle would seal so the floats see the ink as being 'full' by pouring it in slowly. This avoids cross-contaminating your flush with different colors. From there, run a #ADJUST>Subtank>Fill Up Ink and Discharge Ink on each head set alternating a few times until you run through your old ink in the system. Make sure to top off the flush as you go, let the flush sit in the heads/lines overnight. Also a good time to scrub down the underside of the print carriage. If you see ink build up, clean with maintenance fluid (#15/16 usually). Avoid touching the nozzles, but you can safely wipe them down with a wetted down silicone wiper blade if you have one from another printer (newer UJF6042MKII printers use a suction nozzle instead of the older wiper style).

After soaking, remove the cover behind the bottle station as well as the panel just below it. Once you expose the ink valves (10 of them, 8 for each channel, plus 2 more for white recirculation), unclip the line from underneath the grey valve. Take a waste container, put it under where the line was disconnected and push in the valve assembly to drain the ink tank. If changing ink, keep pouring in flush until it runs clear. Now, if doing primer, there is a risk of clogging lines. With the top bottle tank flushed, add even more flush, discharge the subtanks a few times to make sure the lines and subtanks get out all the ink. If you want to check how the cleaning is going, remove the waste tank, empty it, stuff a paper towel in the neck and reinstall. Take the bottle out and look at the paper towel to see how dark the waste liquid coloration is. You want it to be as close to clear as possible.

If reusing the bottle-caps you can flush them by pouring in flush and in and pressing in the button to make it pour out the bottom. Or take an old ink bottle, flush out with isopropyl alcohol and pour in flush to shake down well and press in the button to discharge the now dirty alcohol. Once that's good, install the ink, manually drain the bottle tank by the valve and install your ink.

Reconnect all lines, then do a subtank discharge and fill, twice if you want to go crazy. From here, do a few nozzle checks to see if the ink is flowing properly. Should be good to button up the machine. Next you'll have to do a full reset on ink type (or adjust parameters) to have a PrClrCMYKWW set instead of LCLMCMYKWW set.

If you want to do a primer conversion fully proper, you'll need new lines, new caps, new subtank for the #1 head. However, the parts add up. These printers are typically configured on setup and run their chosen ink set for their lifespan.

When converting to primer, ORDER A NEW CAPPING STATION and LF-200 primer maintenance fluid to use only on the primer channel! Ink + Primer = massive clogs.

If you just want to add a clear channel, I suggest skipping the primer entirely and just running 2 clears (with a permanent primer chip) and just flip between using the primer channel and clear channel between jobs. Not great but saves you from frequent head replacements.

WOW!!!!!!! Can't express how much I appreciate that information! That is outstanding advice. Hopefully I can get that done shortly. The bottom of the carriage looks really good. I expected it to be a hot mess but it was very clean, along with the heads. I think the thing that killed this machine (on price) was at some point, it has a massive white ink leak that appears to have come from the tank area. There must be 1/2 a liter of white ink in the bottom of the machine and every where it could possibly flow. It was shipped without any ink bottles and when it arrived, the pallet had a pool of white ink on it and the machine had white ink dripping out of the bottom of it. I took the back covers off and white ink was about 1/8" deep across the entire bottom.

I did get the service records from the company that maintained it and it looks like they fixed the issue at some point, but I guess no one ever thought to clean up the pooled white ink. The inside of the machine, under the ink bottles is a hot mess of white. I've been cleaning it and it's almost back to normal now.

UV printers are great about being recoverable, as long as you keep UV and sunlight out of them, they tend to clean up decently. For cleaning up old ink inside the body, orange cleaner wipes like Tub o' Towels work pretty well.

The good news is that I put the chips in that came with the machine and it was not set up with LC and LM, it was setup with Primer and Clear. Everything is flushing pretty well, except the primer. It's flushing but no where near as fast as the other 7 stations.

I've run the subtank fill and discharge about 10 times on each head and left it to sit overnight. Everything seems to be going along okay. I have serious concerns that the primer head is not going to be salvageable since it seems so slow to discharge compared to the others, but we will see. If it doesn't clear up, it's not the end of the world. I have primer on my other 6042 so if I need it, I can print on that machine. Would be nice to have it working but it might not be possible this run.

I have a really dumb question. The machine had a brand new set of the ink bottle connectors with it, along with the tightening device. I bought the 250 ml bottles to get started. The caps don't fit the 250 ml bottles. Is there a different set of caps for the small bottles? Or am I missing something?

There are different caps for LUS350/150 and LH100/LUS120, the 250mL/1L caps should be the same. The reason being that different bottles are used to keep the inks from getting mixed, as it will trash the lines, subtanks and heads when the incompatible inks react.

Thanks! I am switching to LH-100, so that explains it. Any idea where to find the right caps for the LH-100? I’m only seeing 1 part number for the set and it’s the same ones I have. I don’t see them in the parts list and can’t find much online at all.

Cap B assembly M014958 AKA SPA-0280. Pricey for about $250-300 for all 8.

Might have a new set in my parts bin if you want me to look tomorrow.

Absolutely! Just tell me if you have them and the details. PM me if needed. Would love to get them shipped out today if that's a possibility at all.
