Greetings Fellow Frustrated Service/Operators People!
I have a bit of a problem with the ol'Konica-Minolta bizhub PRO C6501 (1.3 Million Total Clicks). No matter what grade of stock I run, I cannot get this machine to run properly without it jamming at the registration section. I dismantled the registration section to check the roller, torque limiter and spring. Nothing seems to be wrong with them or the gears.
SIDENOTE: I was experiencing several codes during this process that made it more frustrating, most of which has nothing to do with feeding paper. However, it became necessary to replace the fuser belt and by doing so, it solved many codes in the process. I was having fuser errors due to connectivity (C-3913) and fuser temperature errors (C-3802, 3501, 3908). I don't know who hammered at it, but the back plastic cover was broken and the fusing duct assembly. The cover prevented the unit to make full contact to the connection for the fuser and the fusing duct assembly aligns the lamp, hence all the temp codes.
After all that replacement and code clearing madness, C-2452 hit. Again, nothing to do with paper feeding. So, the developer was due on the Magenta and Cyan units. Replaced the developer in both. Ran all the standard start-up diagnostics only to have color registration issues. Cleaned all the sensors and ran the auto registration and all was well again. Little issue with color/gamma correction C-2840, but that's another story.
Now back to our original story...
This KM is over 1 million prints. It actually prints very well when the sheet makes it all the way through only if I jack up the weight class as a slower print. It can successfully make a couple of 11" x 17" print with few minor flaws. Visually one print might have a scratch on it (buckling, hitting the fuser path) or the tail of the sheet will be a washout, and that usually occurs on a lower weight class.
If there is any questions on my descriptions, I can furnish some image to clarify.
Any ideas or suggestions are greatly appreciated.
Thanks!
