im getting this message on this machine that i just changed all the drums and the itb cleaning assembly. if i take out the drum reinstall it close the machine up the message goes away. it seems to come back after a day or so. do you think this is a bad drum unit or did i not do something when i replaced the drum units? it only has asked for the black drum unit. thanks for your help in advanced.

Re: C3480i install black drum
- ITB cleaning won't fix this but the ITB can.
- dc-con needs to be 61.01 or higher (the detection of drums has supposedly been removed but not always the case)
- secondary transfer roller age is older than the ITB and/or drums.
- Coupling that drives the drum from the back (white plastic spring loaded gear that drives the developer in each drum.
I dread these fricking machines, even with all of the supposed fixes I still run into it once a week.
Try the software first and clear the counter for the 2nd trans roller. -
Re: C3480i install black drum
The problem could be related to a broken, loose, or missing drive drum coupling. In this case the drum drive coupling was dislodged from the black drum drive shaft. This prevented the drum from rotating and caused the machine to display that the drum was not installed.

Re: C3480i install black drum
---------------------------
to add on--
Make sure the conductive bushing on the front side of the ITB assembly for the transfer roller is not cracked. This part cannot be ordered. Replace the ITB assembly. Part number FM2-5522-030.
or--
If you have replaced the drum units and still have this issue suspect a connection to the ITB unit.

Re: C3480i install black drum
Do not replace drum units with new ones unnecessarily, in order to check function operations during service,
etc.
The device blows the drum fuse as soon as it detects a new drum unit and resets the drum life counter to 0.
Even if the old drum unit is replaced immediately, the drum life counter will increment as a new drum unit.
Service Mode:
COPIER > FUNCTION > INSTALL > AINR-OFF
Invalidates drum initialization that is performed when a new drum unit is installed. Also, the fuse is not blown, as it would usually be after drum initialization is completed.
This mode would be used to replace a drum unit temporarily in order to check image quality, for example when trying to trace the cause of a problem.
0: Initialization carried out for new unit. Fuse blown. (Default)
1: No initialization for new unit. Fuse not blown.
Further, this service mode should be set to [1] only when necessary for service. After the service is complete,
the setting must always be returned to [0].
Identifying a New/Old Drum Unit
This device does not have memory in the drum unit so, when a new drum is mounted, the drum life counter value stored in the printed needs to be reset.
The device detects old and new drum units, so that the counter can be reset.
The detection is performed by the DC controller CPU monitoring the fuse detection signal.
When the CPU detects that a new drum unit has been mounted, it outputs a fusing signal and blows the fuse on
the drum unit. At the same time, the drum life counter resets to 0.**Knowledge is time consuming, exhausting and costly for a trained Tech.**Comment

Re: C3480i install black drum
I have had moderate success with
upgrading to dc-con 61.01 over. Clear the durable counter for the 2nd trans roller and verify that it contacts the ITB assembly, the ITB assembly itself.Comment
