I used a unidrum print processor on a uniroller base to process 4 sheets (4 x 5 inches) of FP4+ in 8oz of undiluted D76 at 68 degrees for 7 minutes. All 4 sheets came out with uneven development about 0.25 inches from the short edges. The uneven development shows up as a streak running roughly parallel to the short edges - with a slightly higher density in these areas. Originally I thought that the developer touched the film edges during pouring, but that would cause only one edge of the film to be overdeveloped, not both. Another thought was that the chemistry was splashing around the flanges that hold the edges and thus over-agitating those parts of the film - but again others would have seen this too - and I know that many on this forum successfully use the unidrum & uniroller on a regular basis.
What am I doing incorrectly here?
Thank you in advance for your suggestions.
