Troubleshooting
Table 8-1. Worded Error Messages (Continued)
Message Error/Action
Roll misaligned
Reload roll Roll media is skewed. Unload roll media. Open the roll cover
and push the media roll all the way to the right so that it is
flush against the media stop on the roll core. Reload, making
sure that the left/right media edges are even with the left/right
roll core edges.
RS-232 error
Baud, parity The RS-232-C interface is configured incorrectly. Press the
ENTER button to clear the message from the front panel
display. Check the baud rate and parity settings in the
plotter’s front panel, in the hardware configuration, and in the
application software configuration. Adjust the setting as
needed to ensure compatibility. This error can also indicate a
framing error caused by the wrong number of start/stop bits
sent or the wrong data word length. The plotter expects 1
start bit, 7 data bits, 1 parity bit, and 1 stop bit.
RS-232 error
Handshake The RS-232-C interface is configured incorrectly. Press the
ENTER button to clear the message from the front panel
display. Check the handshake settings in the plotter’s front
panel, in the hardware configuration, and in the application
software configuration. Adjust the settings as needed to
ensure compatibility.
Service pens
Continue Pen checking is ON and an error has been detected. Press the
UP ARROW if you want to service the pens (replace or
reseat). Press the DOWN ARROW if you want to continue
without servicing the pens.
Sheet misaligned
Reload sheet Sheet media is skewed. Remove it and reload it so that the
left/right edges being loaded into the plotter are square. The
leading edge must be straight.
Switch power off
Check media path A servo shutdown has occurred in the X-axis. The drive roller
cannot move or the roll feed spindle cannot freely rotate. The
plotter may be jammed with media. Switch the plotter’s
power OFF. Check the media path and clear it if necessary. If
necessary, troubleshoot the X-axis mechanics and circuitry.
Switch power off
Check pen path A servo shutdown has occurred in the Y-axis. The pen
carriage cannot move. The plotter may be jammed with
media. Switch the plotter’s power OFF. Check the pen path
and clear if necessary. If necessary, troubleshoot the Y-axis
mechanics and circuitry.
