PROCEDURE
Communication is not possible because there
was some trouble with the telephone line. Lower
the transmission speed and perform the
operation again or consult with your telephone
company.
Polling transmission was attempted, but was
unsuccessful because the other party's unit does
not have polling reception capabilities.
A polling request was received but documents
were not set for polling transmission in your
facsimile.
Disconnect and then reconnect the power cord.
If the error remains, contact your service
representative, an authorised service centre, the
place of purchase or the maker (contact
information on rear cover).
