I have a DC242 with around 800k copies that has been great for the past 12 months. However I am seeing some degradation of quality and I think it is time to spend a little money on maintenance. My questions are what to replace to improve it.
1. Faint lines on solids and gradients especially Cyan
Solid colors are no longer completely clean and appear to have very faint lines running vertically down the sheet - more obvious on Cyan (graduated skies for example).
2. Large X which looks like a scratch
Most noticeable on coated papers, this looks like a large X that someone has scribbled on the paper but it appears across the whole sheet approx 3 inches but offset and repeating.
3. A black defect about 1/4 in diameter appears on about every 4th sheet (A4) or 2nd or 3rd sheet (A3) always in the same horizontal position but varies vertically on the page - I suspect a mark on the IBT belt but cannot see it visually.
I've swapped drums around with new ones and it hasn't improved any of the symptoms. The toners are all brand new. The fuser is fairly old - I tried another old one but didn't see any differences but I probably do need a new fuser.
Any thoughts on what to spend the money on to improve things?
