Out going fax is coming black


FIRST test copying. if the copy come out completely black, then the exposure or scanner lamp or contact image sensor is dead,not lighting on. Now if the copy has black only black lines on it,then you can clean the place where the document passes thru where the light of the exposure lamp projects unto the text of the document being scan,which is the small glass on the left side of the platen glass when you open the auto document feeder.NOTE: Lay your document on top of the platen glass & make copy if the copy come out clean as you needed it,then the lamp is O.K. Then the small glass just need to be clean. If the copy is completely "BLACK", then the lamp is dead, or the circuit that control it. In thus case then you need a technician to do it

Do the copies come out totally black or just dark???? Does the copiers scanning lamp turn "ON" when you go to make a copy? If you smell something burning, you may have paper wrapped around the upper fixing roller...

Copies print all black


Make 1 copy with the lid open & verify that the scan lamp is lighting & that the scanner moves. A blown lamp is the most common cause for all black copies.
