BizHub C224e Black developer

[copyman]

Delivered an off lease machine with around 50k clicks on meter. K drum was at 0% but was working fine Print quality was great. 2 months later they called and said print was light. Replaced drum and prints were still light. Pulled K dev unit and noticed mag roller had hardly any dev on it. Went ahead and replaced developer unit and all was good. Ran about 20 pages and all look great! Less than 1 hour later they called and said machine has error code C-2558 which manual says is high K toner level. I read some posts on this forum and internet that this is a known issue. I was going to take some parts off a shop machine and return tomorrow. Was thinking about bringing the toner hopper, new toner and anything else suggested?

Any other ideas appreciated. Thanks

There are 2 C2558 posts running on color bizhubs. I'm sure developer qty in tank is not sufficient. Now ur dv tank is over toned.

Re: BizHub C224e Black developer

The secret to this issue is:

1. Only use genuine KM toner
2. Do not allow ANY consumable part to run too much over life. (IU's, belt & DV units)
3. Keep FW at latest version

Re: BizHub C224e Black developer

Thanks for the replies. I guess I should've asked if you can swap a dev unit from one machine to another? I feel like I'm back working on the biz 250 B&W machines how you would get a C2557 code if you swapped IU's from one machine to another.

Copyman...bh250's really sucks BAD 2557. I had a work around. Want to know?

Machine had only 50k total and drum k was at 0%? Drum should be at 0% when it reaches 70k (not before). Something is fishy with that machine.
For c2558 run some halftone with 255 value and check for toner level every few pages. Stop printing at 6.5%.
Concerning developer depletion check for drums and ITB overlife, Vg and Vb values and especialy values of IDC sensors (should be around 70 to 80).

Drum life is measured by minutes of rotation, not by copy count. If the former user did a lot of small jobs the minutes of rotation would be high so the drum would reach end of life quicker

Re: BizHub C224e Black developer

So can you swap 4 series developer units from one machine to another without trouble ???? I didn't see anything about it in the serv manual. There are a few bulletins on the K/M knowledge base about developer issues. So looking into these as well.

I will investigate further tomorrow with drum rotation times etc when there

Now that I think of it something was strange, when I was swapping K dev unit I noticed the wire for K connector was out of the clasp. My first thought was some unscrupulous dealer had swapped a bad dev unit before returning to leasing company.

Should I be able to salvage the dev unit I put in today? It came out of a machine with only 20k on it. Customer said they were only able to run a few pages after I left. It would reset but throw the code after one page was printed. So they just turned it off. Hopefully I can still use it since it wasn't used much. hate to waste a good unit.

Thanks again for the replies.

Re: BizHub C224e Black developer

Swapping the IU for testing purposes is not a bad idea unless every thing else is OK.
Machine runs stabilization after each cover open so it should adjust to replacement unit. Once again everything else should be OK>

If you worried of wasting new parts there is Dip SW for testing purposes in enhanced security. Turn it ON and fit new Dev and drum and see where it takes you. Dev or drum counter will not initialise.

Hope this helps.

what Dip SW is it? and what hex should be to test it?

There is no HEX.

You do need to enable DIPSW using SoftSwitch.

Check in SM.
