HP 2550L prints dirty bands on each page

[Fernando Peral]

The printer prints well, but it prints with a dirty band of near 2
centimeter width all across each page in the left part of it. For
example, printing in B&W a text page, i can read the text all over the
sheet, but the part of the band appears with a medium gray tone, darker
in the center of the band an lighter in the borders.

The drum is disty too. It has what i think is toner in the two roller,
the white roller and the light green roller. When i clean it completely
(with alcohol), it print well, without the band, sometimes just a few
pages, sometimes some hundres of pages, but in the end it begins to
print dirty again.

I think it may be the drum that it's bad, but i'm not sure. May be any
other part wich is getting the drum dirty? the drum is expensive enough
for not to change ir just for testing pourpouses.

any help?

thanks

The drum and rollers are consumable parts (need to be replaced
occasionally). They don't need to be replaced as often as the toner, but
they do wear out. HP sell maintenance kits for most laserjet printers, so
perhaps you need one of those.

If you don't print much, then perhaps a new printer would be cheaper!?
