The service monitor is useful to find out why the plotter is not plotting what you expect it to plot. It enables you to read the graphics4language instructions that the plotter is receiving from the computer. Instead of plotting the drawing that you send, the plotter prints the beginning and end of the code that would otherwise have been used to plot the drawing.
You need a basic knowledge of the graphics4language instructions to be able to pick out the important information from the printed code. (Basic training is included in the course referenced on page ii.)

3Send the file from the computer through the serial or parallel ports. The Ready LED begins to flash.
4Wait until the computer has indicated that it has sent the file. The Ready LED continues to flash.
5While the Ready LED is flashing, hold down the ALT key and press Service Monitor again.
The Ready LED continues to flash. After a minute, the fan turns on, and the carriage moves to the right side of the plotter.
Instead of plotting the drawings that you sent, the plotter plots the first and last Kbytes of the code for those drawings. The code is printed in hexadecimal and ASCII format. (If the total size of the file(s) sent is not bigger than one Kbyte, only the first buffer is printed.) The plotter exits the service monitor mode if the file(s) sent contain PJL universal exit language.
