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
option is turned
in the Windows Printer Control Panel. You should either turn the
option , 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. : 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.
