Hi all,

I have Pro 920 and need to get to the service mode but utility --- details ---stop 00 stop 01 does not work for me. Could you advise please how to get there?

Re: Bizhub 920

That's correct...

can always enter by holding utility at startup. Not sure why you cant enter.

Now the device prints almost blank pages. the image is very faint and on the top part of the page only. I checked the developer unit, removed the filter sponge from the tope and it looks almost empty. Could that be the reason?

Re: Bizhub 920

Is the developer unit almost empty or the toner hopper low on toner? If the developer unit is low on developer, why? Is it being pulled out or leaking? Check the seals. That model had problems with leaking developer.

sir
due respect to you, but r u really tech or end user?
There could be various reasons for that problem and it is very dangerous if you are not used to such problem solving.
Hope this helps

Re: Bizhub 920

Now you know that the developing unit comes to you empty, and developer must be added, and several service modes run. Did you do any of those things? Preferably all of them? =^..^=

Re: Bizhub 920

I am not an engineer but a technical person, dealing mainly with Xerox and HP.
I have now received this device from the regional office. It was not used for over a year.
I received it with code 3801 error, thermistor issue. I cleaned the fusser from all the rubbish and reset the dipsw 3 1 to 0, error gone.
Now I am having issue with a faint, light copies.
I am attaching images of the developing unit with removed cover and image of the copy quality (ignore the toner spillage on the paper).

Now you know that the developing unit comes to you empty, and developer must be added, and several service modes run. Did you do any of those things? Preferably all of them? =^..^=

I have not run any service modes yet, as don't know which and where, could you advise on this please?20180411_100910.jpg20180411_100903.jpg20180411_101823.jpg

Re: Bizhub 920

Would replace the Developer.
Make sure the toner is shaken up good after that, sitting for a year, in a hot warehouse, may have melted toner

How many total clicks on meter?
How many on drum?
How many on PM?
How many on DV Cycle?
(press utilities, then details)

Re: Bizhub 920

Sounds like you need to start with a full pm. PM kit, developer, drum, etc. Make sure you do all the adjustments.

if the counters are correct you should be making good prints. the toner may be caked up in the delivery system (air/ vacuum ) try adding a few teaspoons directly to the developer mix and test.

Re: Bizhub 920

I think somebody just reset DV,DR counters without changing anything.
When you get new developer it comes in 2 bags and developing unit should be almost full when pour new developer in it.
In the photo it is obvious developer is very low.

Re: Bizhub 920

Would add new DV to DV unit... and go from there...

Bring this machine back to 0 (fresh start)....
and work outwards..

I would check if they cleared parts counters... see what life really is...
