Resolving the Communication Errors (continued)
Step Procedure
4 Determine if there is interference from an external device.
a. Do not use an A/B switch box, dongle key or other peripheral in line with
the parallel cable.
b. If using a switch box, dongle key or other peripheral, remove it while
testing communication between the computer and the Printer.
c. If needed, replace the switch box, dongle key or other peripheral (once it
is determined that the cause of the interference is not the switch box or
peripheral).
d. Alternative: Add a second parallel port into the computer (if a second
Printer is required).
5 Determine the problem with printing from the application.
a. Print a self-test from the Printer as described in the Printing a Test Image
procedure in Section 8, page 132, to verify that the Printer (itself) is
functioning properly.
b. Print the Windows test page that is located in the General tab of the
Driver.
c. Use WordPad (a Windows 95/ 98/ ME/ NT/ 2000/XP word processing
program in the Accessories Program Group).
• Open the program and type: This is a Test.
• Select File > Page Setup and click on the Printer button.
• Ensure that the HDP800 Series Card Printer is selected and click
OK.
• Change all the margin settings to zero (0) and click OK.
• Select File > Print on the Menu Bar.
6 Determine if the parallel port mode is set correctly or incorrectly
a. Verify that the parallel port is set to Enhanced Communication Port
(ECP) mode. (Note: Determine the port mode by checking the Device
Manager tab in the system control panel.)
b. Change the port mode to ECP in the computers BIOS if the port mode is
not set correctly. (Note: Refer to the computer manual for instructions
on how to change Parallel Port mode.)
