Hi there,
Been lurking on and off, but never bothered to actually register (since we have service technicians doing the maintenance of the machine).
Relevant equipment; K-M Bizhub Press C6000 with RU-509 first in line (also SD-506 and FS-521 off the top of my head).
Problem; for some reason the HM-102 (humidifier) in the RU-509 is acting up and eating the drive gear of the M8 motor on the back side of the humidifier assembly. The RU unit and the rest of the inline post processing units were originally attached to a C8000 machine, which we bought used a few years back. At the time, we had to replace this very same motor, because the helical gear was basically gone. So, same issue now, most likely.
Thing is, we've had a lot of jam issues which we thought were elsewhere, but the J-7553 jam code indicated an issue with the RU-509.
So, is anyone familiar with if this is a common problem, and if there's anything that can be done to alleviate the wearing of the helical gear (it's only on the motor, seemingly, same last time)?
Also, seeing as we're not really using either the humidifier at all, is there some way to disable/remove it and still maintain function of the rest of the RU-509 unit? We very rarely use the decurling option, so having the RU sit there is mostly an annoyance (yes, I know it features some calibration stuff and so on). I've checked the service manual to see if there was any way of "disabling" the HM-102 and forcing the path to take the bypass route instead of *always* going through the humidifier. One would think that setting the paper tray to "Humidifier: OFF" would cause the machine to skip by the humidifier path, but it seems not. I don't know if it ever will use the bypass, but have verified the operation of the SD1 solenoid that operates the sector gate that should direct the paper to the bypass route.
The machine is currently inoperable as it stands, since nothing will pass the RU-509. If there is any "quick and dirty" way of disconnecting the HM-102 (seeing as it refers to it as "option" in the service manual) entirely (someone somewhere in this forum mentioned something regarding DIPSW 1-4 on the RU controller board), I would go for it in a heartbeat.
I don't work as a technician professionally, but have a background in electrical automation, so I should be able to perform most tasks that doesn't involve specialized equipment or software regarding Konica-Minolta.
In any way, thanks in advance for any and all help!
