Carriage Axis (Y"axis) Test

The purpose of this test is to verify the operation of the components of the Carriage Axis.

This Service Mode does not include carriage"axis initialization. If the carriage starts somewhere out of the Service Station, it will hit the right"hand side of the Printer when the test begins, and the test will fail. Always make sure that the carriage is parked in the service station before starting this test.

Perform the Carriage Axis test as follows:

1Make sure that the carriage is parked in the service station.

2In service mode 1, press Carriage"Axis Test (Reprint Key).

3The test will start and the carriage moves towards the right+hand side of the printer. It then begins cycles of moving from side to side over the drive roller.

4If the test passes, the Fast LED (LED A) will light up after the first cycle.
