==================================================

check the Primary Charging System, & Potential Control System

check the DPOT value in service mode (copier>display>Dpot>VDM

Hi,

Check whether the preconditioning lamps are connected.

Glass copies are clean & print with no issues.

So your network prints are the only issue_?

Re: new problem black pages ir9070

correct..the top half off the glass copies are a little light. but corrects if i adjust dens.but they are very clean..

Re: new problem black pages ir9070

1 For the raised print, I would suggest trying a different driver, and updating system software
2 For print getting darker I agree with Rachid , you didn't plug in your precon or the wire is broken

Re: new problem black pages ir9070

Changed lamp from another machine that was know good ..no change ..down loaded driver also no change..is there any way the vibration sensors next to cleaning blade can cause any part of this..see a wire that looks to have bad connection..

changed lamp from another machine that is known to work...no change...down loaded another driver..no change...is there any way the vibration sensors over cleaning blade have any bearing on the issue? it looks as though one wire may have bad connection..no codes though..thanks..but there is a change only half the page is black the other half is a little smutty..thanks..1st from glass.jpg2nd from glass.jpgfrom computer.jpg

i made a long extension so i could visually see the lamp come on it doesn't..checked circuit from test harness connector i made to where connector plugs in ,it checked good on both wires..i replaced dc circuit board because of toner waste toner jam up. maybe its gone bad ??thanks again
