Hie, I have roland rf640 it was running ok the past months but this week i have noticed colour mismatch
eg. darkblue coming cyan or lighter and red printing orange so as the rest of the colours.
I have tried cleaning normal several times and medium cleaning and also manual cleaning but its not improving and the other problem is yellow cartridge #2 when i installed the ink it kept on demanding as it couldnt recognise the cartridge and after time it started printing but when i check ink remaining the slot # for yellow its empty...nothing there. please help!!
The most important picture you can take is the nozzle test.
So take a better picture and post that- do it on the media you are having issues with
What media are you using
What color management settings
What are the settings on the printer tabs
Are you using OEM ink
