Running CQ 5.2 on XP, whenever WC fails for me I first try selecting a bigger area on a different part of the drum. The calibration is done across the top of your crop so check it is super clean. If it fails again restarting the computer fixes it for me.
Have you cleaned the sensor lens? Looks like you're getting a fair bit of halation from the bleed visible in the top of the rebate. Might help. Whilst you're in there have a check that the light tube is perfectly centred on the lens - you can toggle the light on with the service program.
Bulb change would be the other thing to try. Certainly looks like it's working well though.
Thank you Adam. I cleaned the lens last night (it was dirty) but still the same issue. I tried to adjust the PMT pots because with White Balance off (switch 6 on), the scans at aperture 1 and 2 were very magenta. I tried to increase green but it seemed to have little impact on the color.
What's interesting is that there is no magenta cast at aperture 4 so it is possible that this is due to light tube not perfectly aligning which impacts the smaller aperture more. Will open up the side covers and try to adjust and report back soon.
Otherwise, the scans are sharp and full of range which I am very happy about.
