Mutoh Falcon Outdoor 46 frustrating problem.

[natanaelvales]

The printer prints black like green, now prints like burgundy, there are no presence of cyan in the impressions, the yellow becomes lime green, I think it was cross contamination I replace the dampers about a month ago, I do multiple cleanings and suck with a syringe thru the waste lines, the capping seals good, the lines are not broken. Yesterday I replace the print heads and now I have good magenta, lt magenta, lt cyan and black but not yellow and cyan by doing nozzle check, but when I send a job some colors are missing.

this is what i do:

Mine does it all the time too. Before I print, I run a cleaning back to back twice. This always works for me.

Cleaning

I do multiple normal and powerful cleaning and nothing change.

Check your pump, I had a problem with the M getting through, changing my color values, and found out that my pup was bad. I switched it, and all was good.
