Ricoh Aficio 3235 C - Black Band periodically

[Zaxxon]

Hi all

Got this black band on the center of the image in the feed direction, when printing.

Parts replaced:

1. Black PCU

2. Black Developer

3. Imagetransfer (unit)

Whats next? hw-power? LSU?

Best regards
Zaxxon

No one?

When you replaced the transfer unit, did you also replace the cleaning blade and cleaning unit? I'd almost bet you'd see that same streak on the brush in the transfer cleaner...

Have a look at your LSU

Check the fusing unit.

The error is very periodic.

If the color of the band in the PDF is accurate as it appears on my computer (the machine I used for years recently bit the dust, and I haven't beat up the new one enough to be sure yet), that band appears to be process black, the approximation of black made by mixing the color toners. If that is the case, check your color PCUs and developers.
