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.

If the band is across the page its likely to be a drum problem.
If the band runs down the page its probably a toner problem.
Usually if there is a drum fault the band repeats itself several times
on the page.

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 which is getting the drum dirty? the drum is expensive
enough for not to change ir just for testing pourpouses.

any help?

thanks

Your problem could be the drum, but is much more likely to be the
toner cartridge.

Taking the toner cartridge out and giving it a good side to side shake
often will clear bits of toner that has caught under the scraper blade.
