No Black color colomn print

Hi, there is a column with no black print (only)

when i swap yellow and Black toner cartridge all is ok (black is yellow and yellow is black)

check: http://dl.free.fr/vXFOTQZym

looking at the image, the missing black column is not sharp at the edge. That would point at a problem of missing toner on the drum, rather than a laser or high voltage issue. What you are saying is when the black is in the yellow position, there is no missing column. If that is correct, than it makes no sense.

That is the problem !

The quality is ok with the yellow cartridge instead of the black one.

but the problem remain if i swap with the 2 others colors ?

only the yellow print well !

It's hard to understand what's going on ?

I tried to change the black one by a new one.....same prob !
