Response to Incoming Document With Errors on the HP FAX-700 and FAX-750
The following tables describe how the HP FAX-700 and FAX-750 determine how to respond to the transmitter when a
document is received with errors. These tables apply only if the transmitter does not have or is not using ECM (Error
Correction Mode).
The signals listed in the tables and their interpretation are as follows:
D MCF (Message Confirmation) – document received with good quality. Continue with next page
D RTP (PIP if during voice request) – document received with marginal quality. Train before sending
next page. (RTP – retrain positive)
D RTN (Retrain Negative) – document received with unacceptable quality. Train at slower speed.
D DCN (Disconnect) – Too many errors. Disconnect and send signal if the error condition is detected
after complete page is received
The following Line Error Table gives the criterion used by the fax machine to determine which signal to return when
it detects a given number of errors on a page being received, and service parameter 46 is set to LINES.
For example, if service parameter 47 is set to 3 and a page is received with 254 lines in error, then the machine responds
with the RTP signal.
