Is the unit set correctly for the type of telephone line in use (pulse/
tone)?
If you have a pulse line, be sure the unit is set for pulse dialing. If you are

feeder?
Remove the document, stack it, and feed it into the unit again.

lines. However, you might have to try again. If the receiving fax unit does
not support ECM transmission, the document is received in the normal
mode without error checking.
Are your faxes failing to be sent?
Make sure your phone line is active and correctly connected to the
MultiPASS printer.
