Hi Folks,
We have a client in the middle of the Indian Ocean that has no hope of tech support. They have a 6 month old OKI C9850MFP.
The issue they have is a very poor print quality. The user has changed the yellow and magenta drum units and also added new OEM cartridges. (They only ever use genuine OKI toners). The yellow and magenta print quality is very grainy and very light. I have sent them instructions on cleaning the LED (but because in the instruction there was a picture of only one LED i am afraid that they may have only cleaned the far left LED shown in the photo and not all four).
BUT does anyone have any other recommendations on what to check on the machine. Its hard to get them to diagnose the components such as voltage to the drum units, so if anyone has had any experiences of this type or error on the OKI's which we have found to be almost bullet proof i would appreciate any suggestions.
The machine is not reporting any user intervention required and i am trying to get them to send me a diagnostics page.
I know there is not much information to go on from what i have typed - but you can see the dilemma that i am in.
Thank you ever so much.
