i was posting with my phone, and the picture didn't attached. Yes, they look like raindrops. this is mono printer, and the drum unit is new.

... grrrrr my picture is uploading, but when is finished its not listed in attachments :(

GOT IT! take a look at the picture.

This is the test page, and the raindrops don't print on every page, but one of several pages. like one page they print, and another four, five don't.

i did that, the drum looks fine. it's hard to disassemble, but i did it, and it's ok. like i said: it's not always, it prints sometimes. I think it's something wrong with the chemistry between toner and developer...
