Overspray when printing black

[signstoptyson]

I am getting pretty bad overspray in cyan, but only when printing black, not cyan (alone). Roland sc540 Sol-jet.

I have tried cleaning cycles, mainenance cleaning. Encoder strip cleaning. Bi-directional adjustments.

The test print looks perfect with absolutely 0 clogs. Does anyone have any ideas? Oh, the black head has been replaced this year.

Was the black head from Roland? Did the rank numbers get entered correctly?

Is the head aligned correctly? Have you had any head strikes?

Did you have the dampers changed with the new head?

Black ink head was the top recommendation from my sales company (the ones who sold me the machine). We only use Roland inks in this machine (per recommendation of my machine sale person and purchased from them).

Dampers were not replaced but have been replaced 3-5 years ago (before started working for the company).

It is on carpet, but it also has been for the last 5+ years never with this problem before. (so I do not think is it static).

In low resolution the cyan overspray is not as bad. Heads are also clean and the wipers have recently been cleaned (they actually were very dirty -wipers- with quite a bit of ink build up. That ink was all removed so they are clean now.) The clean wipers also do not seem to have fixed the overspray entirely.

I recleaned the encoder strip which helped slightly, but not fully.

Any ideas

Hi,

I recommend to replace dampers on black head first. If problem persists, replace on cyan head as well.

Dampers should be replaced once per year...
