Image never prints.
Printer READY light
flashes as if receiving
data, but no prints are
made or the printer
returns to “Ready” mode
without printing image.
Make sure that your computer is communicating with the
printer. At the DOS prompt, type the following in lowercase
letters:
echo showpage >
port:
(substitute LPT1:, LPT2: or COM1, etc., for port:)
The printer responds by sending a page through the print
cycle and ejecting a blank page. If this does not happen,
check your cable, or try a different parallel cable. If using the
serial port, refer to the serial port configuration.
Ensure that the print file ends with a “CTRL D” character.
CTRL D indicates the end-of-file which the printer responds to
by closing host-to-printer communications and then
processing and printing the file. Use a text editor to open and
examine the file. Check and add, if necessary, the following
line to the autoexec.bat file:
mode = LPT1,,,p
(If your port is not LPT1, substitute LPT2: or COM1: for the
correct port). This turns on printer retry indefinitely.
Download EHANDLER.PS file located on the Tektronix
Utilities diskette. At the DOS prompt, type the following DOS
command:
COPY EHANDLER.PS LPT1:
(If your port is not LPT1, substitute LPT2: or COM1: for the
correct port).
The PC responds with
1 FILE COPIED
. The printer now has
a PostScript error handler present which remains resident
until power is cycled on the printer. Send the image file that
was not printing.
Any PostScript errors encountered by the printer are recorded
on a printout. Call Tektronix Customer Support at
1-800-835-6100 for more assistance (save the print with the
error message).
