cross contamination of M lines

[SummitSignsandmore]

My Mutoh 1204 sometime experiences cross contamination of my M ink? When the machine sits a couple days without printing or over the weekend sometime when I come in the magenta lines are cross contaminated black. I have to run the M ink solid for awhile to get the M back to printing the correct output.

My ink cartridges aren't low.

Possibly Dampner for the magenta line leaking slightly somewhere or just not holding and the magenta is sucking black up from the capping station as it drains? Just throwing it out there. Haven't seen this issue on our machine.

Thank you so much for your input!. I'll start with some fresh dampers and see if it will eliminate the issue.

This can also be due to the capping station lint touching the head when it is parked.
