sharp mx 453 light prints and copies

Re: sharp mx 453 light prints and copies

I'm beginning to suspect ATC sensors in the DV units, having this problem a lot these days.
I've checked DV ref (around 46, too low) with 25-1, then taken ATC sensor out and cleaned it, then ran sim again and got 20 points higher. Standard reading should be 84 - 108.
However, we've also been running some compatible toner (guilty) which may not be mixing well with the developer. If the DV reference fluctuates, due to sensor or other DV unit issue, you're screwed.
Pretty sure new DV unit will solve issues but looking for cheaper solution.

had that on one 453 (400k) and two 363 (800k and 2800k). On the 453, replacing the dev unit fixed it, on the 363, i reset doctor blade gap to at least 0.4 mm, and so far so good for 2 pm cycles....We only use oem on those.

Had this problem a couple of times and turned out to be a build up on the mag roller
Hoovered dev unit completely out ,cleaned mag roller and blade with alchohol.New dev and both machines working fine
