Abstract
A reproduction machine incorporating self test routines to test the machine operating logic, particularly at start up, to insure the integrity and operability of the component parts of the operating logic. The tests include routines for initially checking the machine master control module logic and memory. A display panel on the master control module visually identifies any fault in the event the communication link to the machine main display has failed. Once the operability of the master control module is established, self tests of the various machine remote control modules are carried out followed by a test of the communication channel between all modules. Any fault found is visually identified to facilitate repair and servicing.
