Precautions on Using AUTO Mode
• When AUTO mode is selected, the plotter may not recognize the selected interface conditions in some
cases. If the AUTO mode interface conditions are not recognized after several retries, manually select
USER-1 or USER-2 mode and set that mode to the desired interface conditions.
• If you wish to exit AUTO mode while the plotter is awaiting data from the computer, either press the
M O D E
key or reset the plotter (by concurrently pressing the
E N T E R
and keys).
• If the plotter receives data via the Centronics or USB interface while it is awaiting data via the RS-232C
interface in AUTO mode, the plotter becomes unavailable to receive data for AUTO mode properly. In such
cases, immediately start over from powering on again.
• In AUTO mode, the plotter recognizes all of the currently selected RS-232C interface conditions except for
the handshaking mode. After the plotter reads the AUTO mode settings, if plot data is omitted or inaccu-
rately reproduced during plotting, select USER-1 or USER-2 mode and set the desired handshaking method.
• Do not use AUTO mode if your application program contains a READ command that requests the plotter to
return information about its status, model number, etc. Because the plotter cannot respond to READ com-
mands in AUTO mode, sending a READ command to the plotter causes program execution at the computer
to freeze.
• Only the RS-232C interface conditions can be set for AUTO mode. If you do not correctly set the command
mode and programmable resolution before beginning to plot, a command error may occur or the resulting
plot may not fit correctly into the effective plot area of the paper loaded on the plotter. Before you start
plotting, be sure to also set the command mode and programmable resolution.
