AppleFax Modem: Reception Problem May Be Due to Line Noise


TOPIC ---------------------------------------------

I have been having a number of problems with the AppleFax Modem while receiving
from a NEC model NEFAX Bit-1 to my Macintosh SE/30.

The problem was when I was receiving from the NEC Fax; I was able to open and
view the document, but it was nothing but dots down the center of the page. The
document was 227K.

I had the sending end retransmit and was able to read the document the second
time with no problems, but this time it was 127K. Previously, I had been
unable to read an AppleFax document although it showed up as an AppleFax
Document.

Is there a problem with this configuration or with this transmitting Fax? Have
you had any reports of a similar nature? Is there anything I can do?

RESPONSE ---------------------------------------------

Since the problem is intermittent, we suspect that line noise is the cause--not
an incompatibility between the AppleFax Modem and the NEC Fax machine. If there
was an actual incompatibility, you would not be able to receive the document
successfully. The AppleFax Modem has the capability to drop down from 9600
baud to 4800 baud in the case of line problems, but it is not uncommon to have
connections that do not support 4800 baud reliably. We suspect that this had
happened in this case, and the only suggestion we have is to ensure the use of
clean lines from the transmitting machine to the modem.
