text: how to place the roller in the hp laser jet 6l printer?   not easy, first remove back of printer, 3 screws and a few latches a bit higher, may need a screwdriver to prise open. remove drum before doing this. take off front cover. 2 screws form on top, and rest latches. on rhs of assy a white gear wheel with spring will need to be removed and on lhs of same silver bar detach other white thing, and wiggle the assy out, i know this is a bit sketchy but i haven't done one for a while. take note of the positioning of the roller on removing as if not correct the thing wont print, you should really get somone else to do it  who knows what to do . its a bit of a pig.
