I am using an Epson 1400 and Sawgrass bulk feed system but struggled with printing grey. Whatever I do it is coming out purple/blue.
I tried all of the solutions seen on other posts but then when double checking my bulk feed ink system saw that there was ink in the air chambers.
These have been cleaned out with a syringe and I am running a load of purge prints to see if this helps.
Question - anyone know if ink in the air chambers may be causing the problem with grey prints coming out purple/blue or what the air chambers do in the process?
Re: Strange Colours - Air Chamber in Bulk Feed Ink
Your best bet is to go to a place like inksupply.com or like and purchase refillable cartridges. The time and money you will save over a CIS that will never work correctly is huge. In the meantime the only thing that matters is are all the colors printing. A quick nozzle check will tell you if each color is printing. Air in the lines is not neccessarily an issue especially if all the colors are printing. Bad colors is either a result of a clog in one of the color, a poor ICC profile, or your application (Corel, POhotshop, Illustrator) not being set up correctly. Your ink supplier or Sawgrass should be able to check and make sure all three things are set correctly.

Thanks for the feedback. As mentioned the air chambers have had no effect - wishful thinking i guess. I have now got the stage of getting the grey printing on to T-Shirts (even though print looks purple/blue when it comes out of the printer). Unfortunately when I print the same file under the same conditions on to a mug it comes out brown. Changing the dwell times and temperatures to see if that has any impact.
Something is definately not right as I have never had this problem before under the same ICC profile & colour management set-up... So frustrating but thanks for all your suggestions.
Re: Strange Colours - Air Chamber in Bulk Feed Ink
Your icc profile is specific for ink, printer (not printer model!), substrate and conditions.
If you change temperature or time, if you change inks or mugs or anything else - the profile is invalid.
Obviuosly, if you are using a generic profile it was made with the manufacturers printer, a different batch of ink etc. and you can expect a reasonable degree of accuracy, but you should be aware of the limitations. You seem to have found them.
