Prints come out green - thermophot ACP 302

[steveyolk]

Hey dear Lab community,

I was lucky enough to get my hands on a beautiful Thermophot ACP 302.
I did a few test rounds but im encountering the issue that my prints come out green (whites are green)

Troubleshooting:

- Put a developed paper through it, no green - hence it cant be dirty rolls
- The longer the developing time the darker green it gets
- Temperature has been measured and is accurate

Anyone have any ideas?
Attached an image how it looks like

Thanks guys!!

Is the paper fresh?
Is your darkroom really dark, as in no light at all?
Is there any chance of carryover of Blix into the developer?

The blotch on the left border looks like fogging due to light exposure, what happened there?

Hey koraks!

The paper is fresh and the darkroom is completely dark - I have a durst RCP20 as well in the same room and the prints come out fine.
As per carryover the acp is equipped pretty well - shouldnt be an issue / also just put in a new batch of chemicals
As per the left border that was because the paperbox was not closed properly, I use these for test printing.

I tried on different paper batches as well, problem is consistent

Were the racks cleaned very thoroughly before you started using this processor so no cross contamination is possible at all?

What happens if you develop a test print in the dark in a tray in the same batch of chemistry as you're using in the acp? A development time of 90-120 seconds at room temperature should suffice.
