We've been battling this problem for a while now.On multiple machines,the developer goes light,has grey background,or both prematurely. usually 10,000 pages or less.Often I'll find a toner coating on the drum and toner spewed out on the mag roller side and inside the machine.
We've used new & rebuilt units,everything cleaned out & replaced if needed,& checked adjustments on the machine.Nothing changes significantly.Occasionally 05-201 will darken it up some,but rarely.When I do 05-201,I find the % number way lower then it's supposed to be.Why would it be losing bias?
When the dev.mix is changed,all is good until it decides to go light or grey again.
We've been chasing this around for a while,I wonder if anyone out there has any insight to this unusual issue, and would appreciate any input. Thanks.
