QDid the receiving fax machine answer within 55 seconds (after all automatic redialing attempts)?

QIs the In Use/Memory indicator lighting?

QIs the document loaded?

ARemove the document, stack it if necessary, and place it on the platen glass or load it in the ADF correctly. For more information, see Chapter 3, "Document Handling," in the User’s Guide.
