Laser scanner start up error.. First of all need to find out which scanner faulty out of two..
Go to menu scroll to diagnosys, scroll to component test, scroll to scanner test....
If the cyan or black component tests showed a startup failure,
reconnect the connectors (J503) on the laser PCA and (J106) and J111) on DC controller PCA... replace the scanner
If the yellow or magenta component tests showed a startup failure, reconnect the connectors (J501) on the laser PCA and (J106)..Replace scanner..
Before starting better to download service manual to better understand the replacement..
