Error Indication - Brother MFC7050C Service Manual

1. ERROR INDICATION

To help the user or the service personnel promptly locate the cause of a problem (if any), the facsimile
equipment incorporates the self-diagnostic functions which display error messages for equipment
errors.
If an equipment error occurs, the facsimile equipment emits an audible alarm (continuous beeping)
for approximately 4 seconds and shows the error message on the LCD. For the error messages, see
below.
