Hi Mark !
I think, but you may check on Jobo usa site support , that a CPE can't
handle more than 500 cc chemistry without stressing too much the motor.
When I tried to use my Jobo for PMK, I mixed one liter PMK and used 500
cc for half time, and put the other half for the remainingg time.
this is because PMK oxydize rapidly in the foam producing rotation of
the jobo. This way you may be able to go for 6 sheet at a time.
Results where good, but I ceased using the jobo for B&W film as this is
too noisy and too much hassle.
Have a nice day !
