Hi Guys
I have tested this image on 4 MPC300s and all of them do the same. Line on the same shot. When i rotate the image 180degrees the line is gone. Another image make more of a band.
Replaced PCU units
Raplaced Transfer belt
Firmware up-to-date
Print image on other machine MPC2004 and MPC8002 the it is fine. B6FB72C7-D1E2-4967-9ABA-FBA15934C776.jpgIMG_7493.jpg
Is this happening when you copy, or when you print?
When you replaced the PCU's, did you clean the laser glass?
...inquiring minds and all that.
Hi Sorry
Was a print job. The line is on the print short end of the page. Dirty laser will cause a line in the other direction.

What you should do is run individual colours as a test to rule out your print job causing part of the problem

Is it just this one document? What file format? Have you considered the possibility that the document is corrupt? =^..^=
If you'd like a serious answer to your request:
1) demonstrate that you've read the manual
2) demonstrate that you made some attempt to fix it.
3) if you're going to ask about jams include the jam code.
4) if you're going to ask about an error code include the error code.
5) You are the person onsite. Only you can make observations.

Hi
The image is a PDF. I have saved it as a jpeg as well but does the same. There is other images like this also with blue sky that does the same.
If i print the image on a MPC2004 and MPC8002 in comes out fine.
A dirty laser will cause a line along the long edge of the page.
Thanks
Well since it's affecting blue sky, I think that I would focus on cyan for starters. The color in your sky sample is C:82 M:49 Y:0 K:32 with the cyan varying about 6% as you scan in the feed direction.

I have replaced cyan dev unit and pcu. Tested it on 3 different MPC300 and they all make the same lines and banding.
What about fuser motor speed? If the fuser is turning too slow or misaligned the paper could buckle away from the drum in the center. Is the anomalie always in the same location on the paper? =^..^=
