Sharp AR-m317 white lines in the middle of document

[tibbs]

Hello, I just serviced a sharp AR-M317, changed the drum and blade, also the fuser. But now am getting a white line in the middle of the copy. I checked the the dev unit and the transfer roller but the same thing is happening.

can anyone shed some light.

thanks

Check/replace the star wheels on the drum pickers.

Check for toner dust on the LSU slit glass.

Do a panic stop and determine if the toner is even making it onto the drum in the first place. Chances are there's some debris in your dev unit scraping it off the surface as it rotates.

Empty the dv unit, vacuum out, and put in new developer. Clean LSU slit glass.

Though the other choices are a lot more common, I'll suggest that you check the charge grid for any lint. hair, or fiber. I'm talking about microscopic. Once you find it, a tooth brush is a handy tool to remove it.

But to give good advice, I'll need to know more about this void line:
1) Is the line in the feed or crossfeed direction?
2) How wide is the line?
3) Does the line have crisp distinct edges, or fuzzy indistinct edges?
4) Does this line vary in width, length?

I can give better advice with these answers. =^..^=

this would be too easy, but seal above developer roller dipping into the brush? They should be changed nearly every DV change or once a year.
