J-3201/3202/3102, Broken Fuser Driving Gear, Paper Wrinkles
Greetings,
Yesterday I was printing some leaflets for a product presentation on 150 gsm Coated-MO SRA4 paper on the C6500. They were fed through the bypass tray on their long edge. All of them would get wrinkled (see the photos attached), and every 5 sheets or so, it would jam in between the fuser entrance and the discharge corona when the paper was fed through the second time through the fuser in order to fuse the toner onto the second side of the paper.
It would usually spit out a J-3201, and sometimes a J-3102 or J-3202. After removing the front fuser cover and fooling the machine that the front door was closed, I was able to see that the fuser drive gear (P/N: A03U808600) was missing one of its teeth. Also, I didn't notice any play on the 3 one way gears when the fuser was entering pressure mode.
I was able to finish that job, albeit with a lot of trouble. Today, I replaced the broken gear and put some grease on all of the gears in the fuser's gearbox, and tried printing the same thing on the same paper again. And the exact same thing happened. It jammed with a J-3201, and when it was finally able to successfully print one, it came out wrinkled. I then tried printing a 13x19' sheet of the exact same paper, but I only had 300 gsm at hand. It printed it successfully first try, no wrinkled, no fuss, no nothing.
Then I tried printing some random document on some plain A4 paper, and, again, perfect. Feeding the paper from a different tray didn't help at all, neither before nor after the repair on the fuser was performed.
The machine is a bizhub PRO C6500, with ~2,740,000 impressions on it, and with a FS-607 finisher attached to it.
So, here's what's been bugging me, if anyone can take the time to answer, I'd be grateful.
1. Is it just the paper or there's still something wrong with the fuser?
2. After tearing the fuser down, I could see that the fuser drive gear /B (P/N: A03U808201) was looking rather worn and was on the machine for more than 400,000 impressions. I will replace this early next week, and I am looking into replacing as many of them as I can, because, clearly, whoever was contracted to service this machine, did the job rather poorly, to say the least (the fuser duct on the rear of the fuser holding the lamp of the pressure roler had been broken by someone in a haste and the lamp was hanging by a thread when I opened it). I was thinking of replacing all of the 3 one way gears. Are they the ones I have highlighted in my photo (marked 1, 2 and 3) and are they all the same P/N? Or are they all different?
Many thanks.
