Help pls- vertical stripes - HP 8550 laser

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

We moved to Florida (to office with good AC) and brought printer with
us, with all components in box to lessen weight (drum, fuser, and
toner cards).

We set up printer and now are getting vertical white spots..ie. blank
areas...approx. 1 1/2inches wide. They appear at a different spot on
page with each print. Sometimes near left margin, sometimes in middle
of page, sometimes far right. They run full 11 inch height of page.

Any ideas? Thanks.
