Sounds like a problem that I had with a black head on my Canon 4000. My
black only printing had a white band also much like you are describing.
I tried cleaning multiple times with different approaches, all to no
avail. I played with various modes with the draft and normal modes
obtaining the same problem. I worked on putting my printer into a mode
where it printed with the good half only and I got it to work but very
slow. The mode (I can't remember) was something like Hi Res paper and
photo. I believe it was put into a unidirectional scan (probably 4
swipes) which used the good portion of my head.
My analysis is that 1/2 the head is used for one direction and the other
half for the reverse direction. Don't know the algorithms of the Canon S/W
I finally took a chance on it being the print head and purchased a new
one for about $55 and now it works as new.
I don't know how the original head failed, but it did.
Hope this helps,
Geneo
