Vertical white band when printing on MG4120

[steve1022]

On the test page I'm getting a vertical white band near the center of the page, about 1/16" wide. It is shifted slightly on each of the color bars. The black grid at the top has it too. Also, black text has the letters near the center "pulled apart." For examply, a capital "P"is about 50% wider than usual with a white band down the middle of the letter. 

I did all the maintenance stuff. I think it is clear this is not a printhead problem as the coior bands look fine except at the vertical gap. I did the printhead maintenance anyway -- it did not help. 

Seems to me there is a mechancal problem, like a tooth on the printhead drivebelt is broken or something. 

Any tips appreciated.
