I'm using a Paterson Orbital to develop my 8x10 prints (manual agitation). I basically like the thing but have one niggly problem that I could use some advice about.

The top lid of the Orbital has 2 "blades" which are obviously intended to help keep the paper bowed in a concave manner to aid circulation of the chemicals. In about 60% of my prints, I am finding I get 2 white lines where these blades have presumably been in contact with the paper.

So far, I've tried using varying amounts of solution, from the recommended 55ml up to 150ml. I've tried agitating extremely slowly, and also faster. I've spent a fair amount of time trying to seat the prints onto the base of the Orbital because the paper does seem to bow in a convex manner (Ilford MG IV Multigrade RC Glossy).

If anyone can help me to get rid of these 2 lines, I would be very grateful!!
