6500
We have 2 bizhub 6500's used in full blown print production. At first we had service through a private company DPI and could not register, print, or basically complete a job without having one of their techs on site. After we threw them out we went direct with Konica Minolta service and they brought the machines up to par where we at least starting making back our investment. As of now i have gotten rid of the service contract 100% and service myself on a regular basis (no more click charges). i found a field service manual, parts, etc.. Since i have been servicing machine, production has never been higher, and quality has been much better. One you understand how the machine operates from tray to finisher, you will see not much can really go wrong. PM kits are a must, Drum changes are a must, and corona wires must be cleaned weekly. when you get streaks on a job, check corona wires first. if you see a dot on a job in a certain area it is probably a drum unit, and after inspecting drum you usually see the mark causing the problem. if you get some very bad results and all else seems good, check fusing unit, the belt can go bad from long runs due to excessive heat (very expensive belt). color adjustments are easy, just use a sheet printed a few weeks ago and compare to what you have now. best thing to do is leave machine on, this way settings stay for the most part the same. Each morning when you take machine out of standby mode, do an execute adjust operation from the adjustment menu, select all 4 items and return out of the menu, machine will totally calibrate. by doing this, the machine will not change anything in a middle of a job, will run longer periods without saying adjusting please wait. last thing, if you want into the real adjustment menus, hit utility, stop 00, stop 01. do not do anything unless you know what you are doing, but if u change a drum, you will need to initiate it here in this menu. if anyone changes a drum, make sure to remove the red screw in each end.
any questions or info needed, please ask. I have the complete field service manual and parts listing for the 6500.
one machine has over 2 million clicks and the other is at 1.8 million
we also have a 1050 and this machine is an animal, no major problems, and it just keeps clicking away. 2.5 millions click on this bad boy.
