Bizhub 200/250/350

Hey guys! Does anyone know how the toner for the Bizhub 350 (TN-311) can be different from the toner for the Bizhub 200 and 250 (TN-211)when they all use the same developer (DV-310)? I know the bottles are different but one of my techs swaped out the IU from a 350 with the IU from a 250 and as soon as the copier started, it popped a toner sensor code.

What you probably got was a toner density error because the Dev was calibrated for the other machine. The only thing different about the toner is the bottle, We modify the hoppers so they all use the same toner.

Is there any documentation on that modification you do?

And what's the idea behind doing different bottles for machines that essentially use the same toner?

Its the manufactures way of making Dealers carry more inventory. The more types of toner the more types you have to stock.

That mod is just pulling out the drawer the bottle lays in, and removing the rotate cup and pop out the taps that prevent the different bottle from being inserted. When you pull it out you will see what I mean.

Thanks for the insight.

Hi I agree with pepper38, it will probably be just the toner density sensor not correct. But whilst we are all talking about this toner density I have another question about it one of you guys might know the answer to?

when i have changed dev in the past on this range of machines, most of the time after the setup, it throws up this toner density code, and the only way i can get rid of it is by quicky getting into service mode before it puts the code up and changing the manual setting for the toner density, by a massive amount, either one way or the other, i know its probably not the best thing to do but its all i can do to get the machine up and running, it works fine once iv done that.

any ideas why this could be?

The next time you change a Drum and Dev fallow these steps:
1 Reset the special parts counters
2 Shut off machine
3 Change Drum and Dev
4 Reinstall drum assy leaving side door open
5 Turn on machine and enter service mode
6 Close side door
7 Complete F8 adjustment
8 Turn power Off then ON
