Are the black spots on all copies. if they are only on teh copies done from teh glass scan then it could be dirt on the g;*** plate. if from all copies it is the dev or drum area.. are the dots moving across the page in the same place if you do lots of copies this means it is the drum that is damaged.. if they are blotchy marks it could be toner build up.. if the marks are in a line across the page open up the side door adn look at the hot roller in the fuser the coating could be damaged and the roller need replacing..GOOD luck A

Ricoh afficio 1045 & ricoh 450 toner is mixed in ricoh fw 780 now background and negative image is coming what can i do plz give some idea


Hello,
firstly you need to remove the developer and vacume the developer unit and magnetic developer roller.
Put in new developer and correct toner in toner unit.
Call service...
After replacement there is a sequence wich needs to be done, for developer initialization.
