In my manual, a C-225b is the drum motor

the error appeared once, then it did not appear at all. is that means the error still remaingin in machine? or the error is cleared?

From the knowledge base:

Description:
C225B error code.
Solution:

PROBABLE CAUSES:
Shortly after power up
Black drum motor (M18) or PRCB has failed.
Check the M18 connector for proper connection and ensure that M18 has proper drive coupling. If CN13 on the PRCB is connected securely (CN35 for bizhub C452/C552/C552DS/C652/C652DS) and the error reoccurs, replace M18 (p/n A00J M110 00) and the PRCB (PWB-MC) as a set.

• bizhub C451/C550/C650 - PRCB (p/n A00J H001 06)
• bizhub C452/C552/C552DS/C652/C652DS - PRCB (p/n A0P0 H001 01)

Note: If a new M18 is not available, replace the Main Drive Unit (p\n A00J R704 00 for bizhub C451/C550/C650 and p/n A0P0 R707 00 for bizhub C452/C552/C552DS/C652/C652DS).

Intermittently when coming out of Power Save mode
The DC Power Supply (DCPU) is failing.
Replace the DCPU (p/n A00J M404 05 for bizhub C451/C550/C650 and p/n A0P0 R704 11 for bizhub C452/C552/C552DS/C652/C652DS).

If you're a KM tech you should be ashamed for having to ask for this info. If not you should be placing a service call to get this taken care of. Emujo

If it is not displayed on your screen, it is cleared. Sounds like the pcu was in a bind and freed itself up

The post stated c-255b which is the yellow toner sensor.

thank you guys...
i'm end user, and in my country (east africa, Tanzania) we have lack of KM Technicians and Consumables so this is why i've decided to register on this website in order to have technical assistance! Would also like to ask if you know where i can buy toners, iU and other consumable at a competitive price.

Hi Kizi

What consumables are you looking for and for which machines?

Re: KMBH C452 - Trouble Code C-255B

I think you may have looked up C-225B, Zeldaman.

Personally, I'm thinking that the yellow developer is probably failing. If the code returns replace the yellow imaging unit. =^..^=
