This article is a work in progress but contains a few known causes of cross contamination of different ink colours, ie: when one ink pollutes another causing poor colour output.
A few examples of how this can exhibit:
- Cartridge can show signs of another colour ink at the bottom
eg: Yellow cartridge has “green” colour near the outlet (ie: Cyan is being absorbed into the cartridge) - Print output shows a mixed colour output when only the primary colour should show:
eg: Cyan output shows as Purple (ie: Magenta has polluted output)
In terms of cause these are a few things to look for:
- Have you put the wrong ink in the cartridge?
Sounds daft but it’s something to check - Is ink pooling in the capping station (the area that sits under the printhead when the printer is not in use)
- Has the printhead delaminated (ie: layers and boundaries between the different ink channels have become damaged) and ink is now flowing between the ink channels within the printhead.
