Bizhub 368e smearing

[Woxner]

There is firmware for this issue. You also have to change a dip switch as well. Problem only happens after it sits.

I have a bizhub 368e that creates a smear on the first copy only, after the first copy none of the other images have this issue only the very first copy of each job. If I run a job right after it won't happen, only when I let it sit idle for a few minutes and then try again. I've taken the laser unit out and cleaned it, I've checked the drums for wear on the drum but saw none and I have checked the transfer belt to see if there was any wear but I didn't see anything. Ideas?

Ditto on the transfer belt unit-----I would check the belt surface for imperfections. Fuser would be my second suspect. Inspect the ITB belt. Then, you could even inspect the ITB cleaner unit and blade.

Now the firmware is G00-11
Which dipSW need to be changed?

thats the oldest FW out there.
X4 is the latest.

Can anyone add some feedback about the findings? A tech of mine is currently dealing with exactly the same symptome like the sample in the first post. Guess we should swap the fuser.

Look at woxner's answer above. replacing the transfer belt or fuser for "first page only" defects is not the answer. It's more the fuser unit sitting idle not maintaining the temp to fuse the toner properly, especially if using aftermartket toner! Once the first print is out the temp is back up to normal and then prints will be fine.

We updated the firmware. That was the fix for this issue.

Thanks for the info - well we went with the fuser. I've checked the service history and all stuff like firmware, drum, ITB has been updated/renewed during the last 12 months. The total counter was almost 280k - another topic indicated that it's pretty common that the fuser (especially the inital ones) won't last long.

I think my tech arrived last minute so there was no chance to test things - we'll see if the customer calls again next week

Yeah, ours was only around 100k when it started. After updating firmware, no problems since. Machine just now has 250k on it and running like a champ ever since.

Thanks for following up with that info.

Hard to believe fusers would crap out that soon. The "8" series fusers are same as the "4" series and unless they changed something I've gotten 500k+ out of the "4" series fusers. Only issues I've seen with these fusers are noise from the bearings. Very reliable for a fuser without a cleaning or web roller.

I also rebuild the bad fusers (belt, roller, bearings) and they are performing as good or better as OEM.
