Parallel Port Service Check

1.Do a print test to be sure the printer prints correctly.

2.Be sure the printer parallel cable is designed for bi-directional printing.

3.Be sure the user application is set up correctly. Improper set up can prevent establishing a communication link with the printer.

4.Be sure controller board jumper J3 is located on pins two and three. J3 in this position causes the parallel port pull-up resis- tors to be disabled. Some computers have open collector out- puts which require enabling the parallel port pull-up resistors.

Do the following to enable the pull-up resistors:

Turn the printer power off.

Place J3 between pins one and two.

Turn the printer power on and run POST.

Run a print test page from the host.

5.If the printer still does not print, return J3 to the original position.

6.If the internal print test page prints correctly, the user application and printer driver is set up correctly and the correct printer par- allel bi-directional cable is installed. If the printer fails to print on command from the host, replace the controller board.

Paper Feed Service Check

CAUTION: To check the paper feed it may be necessary to run the machine with the covers removed and the top cover interlock dis- abled. If this is necessary, NEVER disable both the top cover inter- lock and the printhead shutter actuator at the same time.

If it is necessary to run the machine to check for paper feed problems, open the top cover and disable the top cover interlock switch. You can feed paper after POST has completed by running the Normal Mode Print Test. To check some of the paper feed for proper operation, it may be necessary to remove the toner cartridge and photoconductor unit assemblies. Do not expose the photoconductor unit to direct sunlight. Keep it covered. The photoconductor will be damaged if exposed to light for any length of time.
