My assessment is a dead print head. The K/C head has been driven by both the K/C signals and the M/Y signal and shows good. The displacement in position is due to the firing timing. This confirms you are getting all the signals from the head board. The fact that the M/Y head doesn't fire at all...

Which Mimaki printers do you have? I'm in Delray Beach and travel around the state.

No. It connects to the board on top of the cutter head.

My first suspicion is the cut tool carriage cable. They are a common replacement for strange cutting behavior.

Nate, It would appear your magenta/yellow head is likely bad. The test prints are a little confusing. You only need to swap the cables in one way. Please do a new test print with the cables in the correct position, then a second test with the cables swapped as follows: 1&2 on carriage board to...

When the cartridge is completely inserted into the ink bay, it positions the ink end sensor arm very close to the trip point when correctly aligned in the slot. The body of the cartridge apparently pushes the arm past the trip point until the cartridge is completely inserted, at which point it...

Make sure the end of the syringe tip is fitting tightly in the bottom of the damper. If you are pulling air, check the O-ring on the ink line above the damper. If you get complete resistance, then a bad damper.

You draw ink through the damper itself, not just the ink line.

The issue turned out to have nothing to do with the printer, but the Roland OEM ink cartridges themselves. The opening for the ink end tab was just a little too small and didn't allow the ink end sensor arm to line up and drop slightly into the slot. Instead, the arm was pushed out just enough...

As luck would have it, I will be in Clearwater Tues-Wed this week. Please call me to discuss, as I will be driving over from the east coast Tues morning and can only do phone calls. 561-441-6658.

You will be better off adjusting the colors in the file itself. Make a copy to do this on so you can go back to the original, if needed. By doing this in an image editing program, you can adjust individual colors. If you are using Photoshop, try adjusting the red level in the "selective color"...

Great people! Glad they helped you get up and running!

Any update on your issue?

You need to do the head alignments in service mode. This will solve your problem.

The old Monaco Profiler Platinum software was excellent for N-color profiling. After reading the patches in, there was a section for changing the behavior of the additional colors. They defaulted to a spot color, but there was a curve controlling this, which could be changed from a steep narrow...

This may be a repair that you want a tech to do, depending upon your skills, as you said you are not a techie. See the attached for the possible causes. They mostly revolve around the magenta damper and its associated fill sensor. Let me know how you want to proceed...

Please post a pic of the screen showing the error code. I know you described it, but I need a pic for clarity to help you. It is a pressure pump timeout related to a damper.

Yes, traffic sucks, but our "blizzards" occur around 50 degrees, lol... However, hurricanes are a completely different story.

First, the internal fill test prints each head separately, pure color, no mixing. Your fill test is fine as far as purity goes. I went back and zoomed in on the printed images and see a lot of blotchiness. Two questions - what is the heat setting and are you printing the images while in service...

You are on the right track to replace the cap tops. Use Roland OEM only. Anything else, you are rolling the dice. Roland Cap Top | Solventinkjet.com The black head may or may not come back. Don't you know that all used printers are working without issues, lol? Buying a used printer is like...
