Re: Ricoh MP 4500 says door open

I was just performing maintenance installing new drum unit and when I closed the doors the message stayed on the display to close door as shown but there is no
open door displayed . I opened and closed each door and watched as the display showed me that the doors were actually opening and closing . But still it displays the message to close door as shown but no door is open . What did I do to create this problem ?

Hi

Please make sure that one of the interlock switch actuator is not broken try to check them using interlock switch cheater tool

thanks

check the cable of the laser unit at the front door, the laser cable may cause this problem.
