ed.2 Trouble shooting 75
##778 (trans) T5 time out (60 seconds) has occurred. Or, the number of times the
protocol signal has been sent has exceeded the limit in ECM transmission after
transmitting EOR-MPS.
Main cause Action
■
The page buffer of the other machine is full
or busy. EOR-MPS has been transmitted.
The RNR has been received correctly, after
transmitting RR. But, the appropriate signal
cannot be received.
■
Increase the T5 timer setting, to avoid an er-
ror.
■
Change the ECM frame size: from 256 bytes
to 64K bytes.
##779 (trans) ERR has been received. After transmitting EOR-MPS during ECM
transmission.
Main cause Action
■
The line condition is poor. Frequently pre-
venting correct reception of the image sig-
nals.
■
The other machine malfunctions: because of
an echo.
■
The line condition is poor. Frequently pre-

■
Press ‘start’, after hearing the first DIS from
the other machine: in manual calling mode.
■
Pause for a relatively long time after the tel-
ephone number, when requesting auto dial,
so that the machine will not respond to the
first DIS.
■
Ask the other party to decrease the level of
transmission, so that it will not receive ech-
oes.
##780 (trans) The appropriate signal could not be received, after transmitting
EOR-EOM during ECM transmission. And, the number of times that the protocol
signal was transmitted exceeded the limit.
