Konica 7165 overtoning

[Will]

Of course I used the correct developer. I've gone in and cut back the adjustment in 25 mode for toner density and developer density soft switches and will continue to run and see what happens in the next 10-20k copies. Didn't adjust the one for image write density.

just incase i thought i would ask about wrong toner as you mentioned this site had bizhub 600/750 as well as this problem machine .we have several such sites and its unfortunately common for tech's and operators to fit wrong toner/dev.
background/gritty line at front end is sometimes found to be charge grid too close to drum and is best solved by removing the grid cleaning pad completely,and alo cutting the spark arrester shoulders back by1 or 2mm
,this has been done toapprox 80 machines so far with good results
much obliged peter
