5.1 OVERVIEW
The EPL-5500W has a sophisticated, built-in, self-diagnostic function that reduces troubleshooting time by
identifying failed parts or components. This self-diagnostic test identifies the troubleshooting problems for
page printers, in which even a trivial failure can result in a serious print quality problem.
5.2 SELF-DIAGNOSTIC FUNCTION AND TOOL
This section describes the self-diagnostic function, in which the controller automatically checks the operating
conditions of each component. If any abnormality is detected, the printer driver displays a message in the
status window.
If an engine error is detected, the printer driver displays a “SERVICE CALL” message. This error message
does not display error information details. To isolate the problem more, you must read the engine error status
register of the printer using a special tool. This tool is program for Windows 3.1.
The procedure for using the program is as follows:
1.
Connect the EPL-5500W to the PC’s LPT1 port, and power the printer on.
2.
Start Windows 3.1.
3.
If you are using the EPL-5500W printer driver, you must change it so that it does not direct output to a
printer. (If you are not using the EPL-5500W printer driver, skip to step 9.)
CAUTION
The tool program cannot run if EPL-5500W printer driver output is directed a printer port in
Windows 3.1, because the EPL-5500W printer driver and special tool both use an interface
protocol program. The interface protocol program for the special tool cannot be active in Windows
3.1 while the interface protocol for the EPL-5500W printer driver is active.
