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 printer￿s 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￿
