8Ć8 Troubleshooting C4699Ć90000
Error + Ready
: There is a problem with the serial interface. Try one or more
of the following:
D Ensure the plotter's settings for baud rate and parity are the same as those
of the host computer. To check the plotter settings, use the setup sheet.
(Instructions ' User's Guide, chapter 1.) D Also check your interface cable
and connections. D This error may also occur if you send a drawing for print
using a Windows driver when the Fast Direct to Print option is turned OFF
in the Windows Printer Control Panel. You should either turn the Fast
Direct to Print option ON , or send the drawing to a file and print the file
from the MSĆDOS command line through the serial port. D If the host
computer is an HP 712 workstation, you may have some problems using
baudrates of 19200 and 38400. Check if recent service notes have a solution.
D Check to see if the Plotter or PC is badly configured. D Check for an error
in the host computer. D Replace the electronics module.

Error + Load Media
: MediaĆload error. Try one or more of the following:
D Check that the media is aligned and that the correct media size is loaded.
Try to load it again. (Tips ' User's Guide, chapter 4, and mediaĆloading guide
C3190Ć90162.) When you begin to load media and push it into the plotter
with too much force, too large a buckle forms in the media. The roller is then
not able to correctly grasp the media and misaligns it. Instead, load the
media so that the sheet buckles only slightly. Neither should you load the
media too slowly. Do it in one brisk movement.
D Clear any binding in the media axis. Caution: Do not pull media along
the carriage axis - you could break the mediaĆsensor flags. D Are both
mediaĆsensor flags installed? D Replace the media sensor.
D Reconnect or replace the trailing cable. Make sure that the trailing cable
is positioned under the plastic tabs at the back of the carriage cover, and not
above them. D Replace the carriage.
