Konica 7255 (Di-5510), Blank no image on paper

[copyman]

Blank pages when printing or copying. No codes

Developer unit turning, gears good.

Tried new T/S corona unit.

Swapped Charge corona unit.

When I swapped the charge corona I got a black
band down the page from the corona wire cleaner
being out of place. Doesn't this confirm that
developer, charge & transfer are all working good?

Anyone ever see this or have other ideas for blank pages?

Thanks in advance

If you believe the drum is being charged, check for something that may be blocking the laser.
Hope this helps

Laser is bad
