Remote troubleshooting (call agent) 1. This error never appears in the Front Panel, it’s only logged into the Error History and is equivalent to 1 long beep during printer startup. It happens when the MPCA communication fails. 2. To troubleshoot this error, see The Front Panel is blank (the printer does not start). 3. If a service engineer visit should be arranged to replace the Main PCA, take into account the model of the printer (the Main PCA is different for Pro and Basic models).
Onsite troubleshooting and solution (service engineer) 1. Remove covers and check that all the cables in the MPCA are correctly connected, and that none of them are damaged. If any cable is disconnected then reconnect it, and power on the printer again to check if the error message has disappeared.
