Black trace (1cm) on HP970: how to remove

Archived from groups: comp.periphs.printers (More info?)

Hi,

Tryibg to print (manually tablet ) two sided on a hp 970cxi, i get a black
trace of one cm at one third of the paper: the trace is strong at the
beginning and disappears afterwards, in leaving some black dust on the
paper.

Does anyone knows how to remove this ? F.ex. in cleaning the printer
(all hp support cleaning actions have been tried)

Tia,
Paul
