2 new Transfer belts TR8550 are doing this.

When I put the old one back in it goes way.

Drums and dvs we're recently replaced too.
OEM toner.



Edited post:
Seems like lines only appear and stays on the belt where it doesn't clean off during a calibration (U464, U469...)

Otherwise copies and print jobs are pristine and clear from streaks: see here

I've seen this issue where one of the pins on the transfer belt harness was bent and not making connection to supply power to the transfer cleaning motor. The machine didn't throw a 1950 or any codes. Check your pins where you plug the transfer belt in. I've also had to put some cardboard behind the connector on the belt itself to push it far enough forward to make good connection.

Please take care for enclosed check points

Thanks Kyo. I've seen these particular marks when I've had a Hanabi primary transfer belt unit apart, and I forgot that spring at the front left ... that provides a bias voltage for the cleaning roller.

Blackcat where is this spring located? Front edge of transfer belt? Sry I'm not in front of one at the moment

On Hanabi KM-2550ci transfer belt unit it's on the front left. I can't say if that same layout is used on the Iris2.
