My wife brought home these samples from work. Just started happening today. Black toner marks than blank streak down the whole page in NON-feed direction. I marked the lead edge. I know the fine black line is from fuser and in the direction of feed.
Never saw this before so figured I would ask on here before going out to look at it tomorrow.
Thanks for the help
Wow! That's nice!
I'd say that it's probably dumping developer because the drum is arcing to the primary. Order drum unit with primary, and developer (along with your fuser). =^..^=
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.

Take a look at magnet roller on developing unit.Originally Posted by copyman
I would say one side has worn bearing or collar and is too close to the drum (spots), and the other is too far (white void).
Check consumables life!,
If you have in stock, bring with you new drum unit, developer, developing unit, fuser (or upper fuser roller).
Problem solved
You can get similar issues when replacing a drum without resetting the chip. Sometimes background data reset will resolve.
Hi, Thanks for all the replies. It turned out the drum was shorting because the Dev collar was worn. Replaced drum & developer unit and all good now.
Who ever posted about the drum chip there in no drum chip on the Biz 223. Counter is cleared in service mode.
