Service Mode 2
Service Mode 2 contains tests that do need a complete initialization of the Printer This means if there is a system error in normal mode it is NOT possible to enter into Service Mode 2 If possible try entering into Service Mode 1 and performing the tests there
The tests in service mode 2 DO NOT send test information to the printers serial port For some of the tests you will need to print the Service Configuration Plot Details ' page 4029 in order to check the results
