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.

differs from the Parity setting of the
serial interface of the printer.

data until the error is canceled.

Buffer; the signal sent by the printer to
the Host PC will be ignored.

data until the error is canceled.

Cover Open
Error
Olivetti emulation: the printer
receives printing data, printing start, bit
image or vertical position change com-
mand 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
opened during the printing process,
the print-out will stop and the LCD dis-
plays Cover Open. After closing the
cover the message is deleted and the
printer will continue the print-out.
If paper is inserted in the printer with-
out 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.
