Bizhub 751 half the page printing lighter

[inkstrum]

On the operators side the print is lighter as it moves to the edge, so the wall side is good but slowly gets lighter toward the operators side of the sheet. Machine has had recent PM including developer, relatively new Developer Unit, new Corona Unit, new Transfer Separation Unit and tried several drums. This is driving me nuts! Any ideas are welcome.

It could be so many different things. Are you a tech? What have you done so far? Have you slid out the process unit to look at Primary corona, etc. Or the transfer corona? Good place to start.

I think the first thing I'd check is to see if the transfer wire is buried under a mound of toner. Even immediately after a PM. These machines could be toner pigs. =^..^=

ok what the others have mentioned...


But..

Did you clean the ROS/LASER glass? maybe break it down to inside lens/mirrors...

BC mentioned "Toner Hogs"...

is IT level? you mentioned light on CTL PNL side of print.. that would mean .. unit tilted to WALL/back

also could it be compat toners?

you never mentioned PRINT or COPY ? Copy..did you clean the Glass/Mirror/Lens thought the copy process?

What are the counts on the copy process units .. and did you do proper install/adjustment procedures?


other than that..roll it to the parking lot.. pull out your pistol.. unload your magazine ( I prefer .40cal S&W 8rnd FMJ wad cutters.. but.... :cool: it's up to you! )

Ha-ha ....There's that Phil again interviewing posters because the lack of information provided. Phil would of been a good dentist the way he has to "pull teeth" with these posters:rolleyes:

Seriously people, it's like beating a dead horse, the more information you provide in that initial post the more precise answers you will receive. Other than that if you give limited infomation you are going to get a bunch of off the wall guesses! I don't like to guess so I won't even answer. If I have the time I will ask a few things like Phil did, but a lot of times I will pass right by the post.

Have to investigate that.
Yup kinda a pet peeve even when I was responsible for 5 techs and 2 toner refurb and part time maint/shipping..
