    Sharp MX 363 Black dots on page

    Does anyone know what would put tiny black dots on page? It does not happened all the time. I checked everything and I cant seem to find what causes this and It dont appear when I check the copier out. Its like little speckles that all of a sudden appear on all sheets.

    Printing or copying? Is it random dots or in a pattern?

      I've seen this happen when a tech doesn't properly put the seals in the process unit correctly, or when the outer blade is warped and there is spit back of toner and it leaves speckled dots all over the media.

        Have had this happen 2 different times that were not copy/print related. Both times had to do with scan or fax settings. Had to go in and fiddle with sim 46 settings for each to get the black dots to go away. Not sure if it relates to your problem but worth a look.

        Good luck.

          If they are faint I have seen these machines overtone and cause problems like that.
