Question Canon Colorado M Series Persistent Errors (#11526 and Magenta Drop Shadows)

FireSprint.com

Trade Only Screen & Digital Sign Printing
We have two persistent errors with all 3 of our Colorado M series printers. We have not gotten a solution out of Canon for these whatsoever. They send techs out weekly with no resolution.

Curious if any of you have found a workaround that run these?

1.) Error 11526.
As you can see, my production team emails alot about these errors causing ~30 minute slowdowns to production. It ruins the current print, and causes us to do a hard restart.

2.) Drop shadows converting to Magenta on certain gloss prints:

We see this from time to time. The typical solution is to fully rasterize the image. The challenge is, like many of us, we get artwork from all over. The magenta drop shadow doesn't appear in any digital file, just when printed. We typically can resolve the issue by fully rasterizing the image first. This is a resource intensive step. We have spoke to Canon, Adobe, and Onyx about this and they all blame each other of course.

Magenta shadow is probably due to RGB Transpancies. Rasterizing is the only correction. Do you have an automation systems for preflight?

11526 - Has Canon ever changed the drop detectors? It's typically caused by detectors that are taking too long or proving erroneous reads

I'll ask about the drop detectors.

We do have alot of automation in preflight. The issue is, we can print the same file on our Durst printers with Durst RIP, our Konica Minolta, or Brother Copier, or look at it on any screen, and there is no magenta drop shadow. Only on the Colorados. We're trying to avoid rasterizing everything. That will end up being terabytes and terabytes of additional data moving through our system.
 
I have found a "partial solution" for the so called "Magenta Drop Shadows" - In Onyx in Job Editor, at Color Management, choose the profile setting: European Colorimetric (Precise)
I printed the file and the color of the shadows are pretty much acceptable.

Thanks all
