Colour Change

[StevenMcfadden]

I am currently printing a lot of car park signs, the background is orange but it keeps fading to a pink colour, i have not had any error codes on the printheads, and the maintenance cartridge has 10% left, do you think i need to change any printheads or the maintenance cartridge

[StevenMcfadden]

I have changed all the printheads and the maintenance cartridge and the problem still persists

Faulty yellow printheads, faulty yellow ink cartridges (or cartridges are not shaken before inserting or not shaken before long prints), air in tubes, faulty ink towers for yellow magenta printheads (those are needles where heads are inserted into)... When  stopped printing, just take out printheads and see yellow/magenta ones if nozzles are inked.. or just hake one head vertically once or twice softly and see if ink comes out of nozzles... To be sure - clean all contacts of all printheads and in carriage too....
