gauges at the left and right ends of the platen.

10.

Pull the Timing Belt to move the carriage to the left end.

11.

If the carriage does not come in contact with the gauge, make the adjustment

again.

12.

Pull the Timing Belt to move the carriage to the right end.

13.

If the carriage does not come in contact with the gauge, make the adjustment

again.
