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 or other peripheral in line with the parallel
cable.
b. If using a switch box or other peripheral, remove it while testing
communication between the computer and the Printer.
c. If needed, replace the switch box 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 Running the Self-Test
procedure in Section 2, page 87, to ensure 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 > Print on the Menu Bar.
6 Determine if the parallel port mode is set correctly or incorrectly.
a. Ensure that the parallel port is set to the Enhanced Communication Port
(ECP) mode. (Note: The port mode can be determined by checking the
Device Manager tab in the system control panel.)
b. If the port mode is not set to ECP, it will need to be changed in the
computers BIOS. (Note: Refer to the appropriate computer manual for
instructions on how to change the Parallel Port mode.)
