Rocking gently back and forth is best. Shaking can introduce microbubbles in the ink, which may take some time to completely dissipate. These microbubbles can travel to the printhead and cause nozzles to drop out, making you think you have some kind of parts problem, when it is just air bubbles...

Not sure which of the nozzle tests in that whole string posted in the last pic is the last one. Please post a single pic of the current nozzle test. Only use Roland OEM caps. Anything else is a crap shoot. I know from experience, having been burned by aftermarket caps. You also want to make sure...

Concerning the head rank, when you get to the dots, you can change them to numbers and characters. This may allow you to use the head. However, how well the head prints is unknown. You will also need to change the manifold to a solvent manifold and be sure to clear any water based ink out of the...

If the last posted pic is the most recent, I'm still concerned about head damage. Can you take a clear well light pic of the bottom of the print heads please? You will need to do alignments with new print heads. Which Digiprint, as there are several, some OK, others not so much. Perhaps a link...

You should check the output transistors on the headboard. They are the transistors mounted to the big heatsinks. Read the outer 2 legs of each transistor, they should read around 42 ohms. They are marked as C4131 & A1746. Most likely you are going to find one or more are shorted and this will...

Nate, To be clear, you are reading 0 ohms on the transistor circled in the picture, correct? If so, that is a short, not an open, and will continue to blow the fuses until it is replaced. Once it and the fuse are replaced, you will be able to determine if the printhead is ok. If the fuse blows...

Rasterlink profiling can only be done with Mimaki Profile Master software, which is specific only to Mimaki and is around $2800. Depending upon how important the 3 printers color match each other and how many profiles you need, Onyx and an i1 Pro2 or i1 Pro3 might be a better long term option...

Agree it could be a dirty section of the encoder strip. I prefer acetone instead of alcohol. You will need gloves, a clean microfiber cloth and acetone. Yes, acetone... It will not damage the encoder strip in any way. 91% alcohol is ok, but doesn't get all the ink off. NEVER use alcohol less...

It would be helpful to post in English, so you have a larger pool of users to help you.

If I remember correctly, the grooves in the bracket fit the "flanges" on the cut and print carriages where they connect magnetically. If you position the bracket correctly, the slot in the bracket will line up with a corresponding hole in the frame, either the platen or the head carriage frame...

On the road today. Please call me. 561-441-6658.

Consider laser etching them and then filling in the etched section with the dishwasher safe paint or ink designed for use on glass.

What would the service call code be? Detailed info is important...

As I said before, recheck the condition of the head ribbons. If they are ok, it is possible the head is damaged.

For me, getting a refurb head would be the choice only if a new one was was no longer available. Plus one doesn't know how well the refurb cleaning was done. Any ink that wasn't removed during the cleaning process may end up drying inside the head, with resulting permanent nozzle loss. Also, if...

Definitely need to change the C/K head. Can you post a pic of the latest test print to show what the M/Y head looks like?

Netsol, I had the top end model and primarily cleaned Ricoh Gen 5 heads used in InkCups UV printers. Success rate was around 30% in recovery, but UV ink is tough and Ricoh Gen 5 heads are robust. My success with the few Epson heads I did was only a marginal improvement and usually worse then...

Epson heads are rather fragile internally and ultrasonic cleaning has a tendency to damage them unless you are using a system that is designed specifically for that purpose, such as the Print Doctor system, and even that system is only marginally successful on Epson heads, and it is a very...

Which printer model? This is typically caused by a head ribbon cable being either damaged or not inserted correctly, causing the head to go into a "free firing" mode. Based on your previous posts, I would recheck the traces on the ribbons to insure there is no damage to them. You said you...

See attached. I can't help you any further than this as Epson doesn't give board layouts or schematics. I would suggest you look for any fuses on the mainboard and test them. Good luck!
