Framing Error
(Serial I/F)
The Stop bit is not detected by the serial
interface.
“?” is printed instead of the received data
until the error is canceled.
` If STOP/EJECT key is pressed, the
error message is canceled and the
printer is in offline (STOP) state.
` Make sure the Baud rate, data bits
and stop bits of the printer match the
PC communications port settings.
Parity Error
(Serial I/F)
The setting of Parity of the Host PC differs
from the Parity setting of the serial inter-
face of the printer.
“?” is printed instead of the received data
until the error is canceled.
` If STOP/EJECT key is pressed, the
error message is canceled and the
printer is in offline (STOP) state.
` Make the Parity settings of Host PC
and printer compatible.
Overrun Error
(Serial I/F)
The data sent by the serial interface
exceed the currently prepared Overrun
Buffer; the signal sent by the printer to the
Host PC will be ignored.
“?” is printed instead of the received data
until the error is canceled.
` If STOP/EJECT key is pressed, the
error message is canceled and the
printer is in offline (STOP) state.
` Check the protocol and/or the hand-
shake of the serial connection.
Cover Open
Error
Olivetti emulation: the printer receives
printing data, printing start, bit image or
vertical position change command while
the cover is open.
` When Reset Error Command or
General Reset Command (PR2) is
received, if the cover is closed, the
error message is canceled, and it is
in an online state.
` If STOP Key is pressed, if the cover
is closed, the printer is in an online
state, and the error message is can-
celed.
Cover Open
Error
Epson/IBM emulation: If the cover is ope-
ned during the printing process, the print-
out will stop and the LCD displays Cover
Open. After closing the cover the mes-
sage is deleted and the printer will conti-
nue the print-out.
If paper is inserted in the printer without
any print data and the cover is opened, the
paper is ejected, the LCD displays the
message Remove Paper.
` If the cover is closed, the printer is
shifted to online state.
` If the cover is opened during other
errors (e.g. Paper Jam Error, Paper
Length Error) occur, the LCD mes-
sage will not be changed. However,
if the cover is closed in that error
state, those errors will be canceled.
