Transmission errors
T
.1.1 The remote fax machine didn’t respond to your machine. Call someone at the
remote machine.
T
.1.4 Someone pressed
STOP
at the remote unit in the middle of the handshake
(the very first part of the fax communication, when the two units “agree” on
the settings they’ll share).
T
.2.1 Either the phone line disconnected during transmission or fax communica-
tion became impossible due to bad phone line conditions. Re-try the call.
T
.2.2 The two fax machines were incompatible. Your fax machine sends and
receives only
ITU
-
T
Group 3 (see “Glossary,” page 3.17) fax communication,
the industry standard since the early 1980s.
T
.2.3 Bad phone line conditions made fax communication impossible. Conditions
can change rapidly, so re-try the call later.
T
.3.2 The fax machine didn’t detect the silence indicating the call had ended.
T
.4.2 After transmission began, poor line conditions developed. Re-try the call.
T
.4.4 Poor line conditions prevented transmission. Re-try the call.
T
.5.1,

transmission failed (perhaps due to line noise). Conditions can change
T
.5.2, rapidly, so re-try the call later.

T
.8.1 A compatibility error occurred. (F-150 only.)
T
.8.10 Line noise or other problems prevented line probing. (F-150 only.)
T
.8.11 The remote fax machine didn’t complete the equalizer training phase.
(F-150 only.)
“Check Message” printouts
When a fax call goes awry and your machine detects an error, it produces an error
printout headed by the words “Check Message.” This printout lists the following
information about the transmission:
• The resulting error code
• A communications error message (see “What error messages can mean,” below)
• The phone number (or, perhaps,
TTI
) of the fax machine with which your
machine had attempted to communicate.
What error messages can mean
The error messages on Check Message printouts can mean a variety of things.
Here’s a brief summary:
Error message Possible meanings
Check condition of • Remote machine malfunctioned
remote fax • No “handshake” signals from remote fax
• Wrong phone number reached
Repeat transmission • Poor phone line conditions
• No “handshake” signals from remote fax
• Document misfeed or miscount
• Unable to reach remote machine after
attempting specified number of redial tries
Line is busy • Remote machine’s line was busy
• Remote machine’s line didn’t answer
Check received documents • Remote confirmation signal not received
from remote fax
• Poor line conditions caused a poor image
Memory full • Remote fax’s memory capacity exceeded
Dialing number is not set • Stored phone number failed to dial properly
Stopped • Someone pressed
STOP
at the remote fax
in the middle of the “handshake”
