Back side lines could from PTR, fusing unit pressure roller or paper guide ribs.

Sample of the line please, put bias setting back to normal, how is that supposed to fix a line.

I would replace drum next if PTR doesn't fix. Looks like what the 301 does when the drum is starting to go on it. Usually only does it for the first few pages of a job.

That looks like the ptr change the developer and any other parts within pcu make sure mag roller is clean before you replace developer then set up also make sure all filters are clean and vac or blow toner from machine

Re: Ricoh mp2501 back side lines

I have to agree with the other guys, change your Dev, drum and cleaning blade. Make sure you do the developer initialization.

Also clean your reg roller and reg roller cleaner.

And 1 more thing on your PCU, the plastic part of it that sits just above the reg roller and below the mag roller , put a strip of tape on it from left to right.

Please check the sample copy

If that is the lead edge, you definitely have a dirty PTR.
