Causes
Memory data in KRDS is different
from that in copier when turning on
copier.
Communication IC error is detected.
(parity, framing error, etc.)
Error has occurred in control signal of
modem cable (RS232C) connecting
KRDS to modem.
Modem control command error is
detected. (For KRDS, this error is
indicated after retry is repeated 10
times.)
Communication IC error is detected.
(parity, framing error, etc.)
This is indicated if immediate stop is
specified for KRDS DIP SW byte 39
and 40.
(Remote control is available from
copier or host computer.)

operation is disabled.
byte40-bit0:STOP and byte39bit5:copy disable
Error is displayed in message and
magnification indication area. Copy
operation stops after the serial copy is
finished.
Releasing
method
Initialize KRDS
memory so that it
can be consistent
with that for the
copier. (Re-execute
set up procedure.)
Then complete byte
33-bit0.
Same as the above
Check if the modem
power is turned on.
Check if the cable is
correctly connected.
Turn on copier after
modem set up
(memory DIP SW
area) is checked.
Set to byte40-bit0:copy
and byte39-bit5:copy
enable, then unlock the
immediate stop.
(Remote control is
available from copier or
host computer.)
