    White Copies after replacing DC Controller PCB (Canon IR 7105)

    Hello Everyone,

    I am facing an issue with a Canon IR 7105. Due to an error (E 00733-001) we replaced the DC Controller PCB. I followed the tech manual and performed all the steps outlined there for the after replacement. However, copies are always white. any help is appreciated!

          We checked the connections. We replaced the Board with another one in stock. at the begining it was printing very dark. after following all the directions, now it is printing super light. seems like a calibration or value may be off. do you know which value it could be?

              The same thing happened to me when I changed the dc controller. I printed super light, changed the complete development unit and solcuione.






              thanks
