Bizhub 368e smearing

**Gina82** · 02-14-2020

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?

Hey, it could be simpler than expected (but expensive!). In fact, it is likely that you will have to replace it.

458e image quality black stripe

Your stain seems to come from the fuser. This for me is a known problem in the 8e series which, oddly enough, already at just 200-250k starts to have problems with strips coming from the fuser roller.

If you turn it manually and you look at the surface of the fuser roller, you will notice some signs. If you leave it like this, toner build-up will increase and the streak will soon become more noticeable.

Any idea why it only does it on the first copy and no other?

Because it probably cleans itself after a cycle and remains dirty in the end. It may be that by increasing the fuser temperature, this problem disappears. Do you use all OEM?

**Gina82** · 02-14-2020

Yes, I use all OEM parts and it doesn't look like there are any dents or creases in the fusing unit. In fact, it actually just stopped, I went away for about an hour and gave it time to sit and re tried it and the copies look totally fine. It's driving me crazy, the parts seem fine but I know something is causing it and I don't want it to come back later

Give us total counter and parts life list to start with. Indeed it looks like fuser mark.

I think it looks like a mustache.

Take a look at the primary transfer belt. If you get a puncture or wrinkle in the belt it will fill with toner while passing the primary transfer cleaner leaving you a "mustache" that appears approximately once every 4 pages.

I have similar issue on 368e also.
It occurred on first print, ONLY on first copy and 1st paper tray, 2nd to 4th trays and bypass OK.
I got several pages of first copy on 1st tray, and the smear hold on fixed position.
Checked drum, transfer unit are all good.

still not fix this case.....
