ECREASE THE TRANSMISSION SPEED OF THE FAX MODEM
The modem of the printer can transmit data at 33,600 bps. This is the maximum speed at which the printer can
send and receive faxes. It is not necessary, however, to set the modem to its fastest transmission capability. The
speed of the modem of the receiving fax machine must match or be greater than the speed at which you are
sending your fax. Otherwise, your fax will not be received.
