9-22-94                    Cannot Fax V-series

     As hard as the developers of the code try, there will always be a  fax
you  can't Send to or maybe Rec'v a fax from. There are too many  variables
to promise you can connect everywhere. Hundreds of makes and models of  fax
machines,  hundreds of makes and models of faxmodems, ROMS, and  of  course
dozens of software packages with their different versions too. In a perfect
world  all  would be compatible. But it's not, so it's just  impossible  to
make  every one perfectly compatible (even between fax machines).
     The Zoom V-series (V32 & V42bis) modems support both Class-1 & Class-2
fax.   If  your software also has the Class1 driver try  that  on  stubborn
fax's.  Very often, one driver will work when another does not. One is  not
'better'  than the other, just different.
     >>>  Class-1 seems to work better on some 'noisy' lines and  sometimes
negotiates between pages better than Class-2. So you may be able to Send or
Rec'v a fax with Class-1 that you can't with CLass-2. <<<

     Also  try setting a slower speed, (or tell the sender to try a  slower
speed)  in case the connection doesn't support your highest fax  speed.  If
you  have  the 14.4 fax (because most fax machines only support  9600)  try
setting 9600. It may possibly be line noise in which case 7200 or 4800  may
work. Sometime you might have trouble with 1 fax machine you usually fax to
OK.  This  may  clear up if you call right back  (you  will  get  different
connections).  Or the phone company may be routing the call on a  different
route for a few hours or even a day.

* At  least  1  fax machine (Panasonic) needs to  have  the  'frequency'
changed  on  the  FAX machine to receive from a  Faxmodem.  A  Brother  fax
machine  also needed an adjustment to rec'v from a faxmodem.  Other  brands
may need this change too.

     Most Zoom V-Series Faxmodems come with both Class-1/2 drivers.
