If the test fails: Switch OFF the Printer and manually moving the carriage along the slider rod, check for obstacle or friction in the X*axis. Check for a faulty or badly connected X*axis Encoder Cable. Replace media motor. Replace electronics module.

Bench Run

THIS TEST HAS BEEN DESIGNED TO BE USED DURING THE

MANUFACTURING STAGE AND NOT IN THE FIELD. DO NOT AT ANYTIME

ENTER THIS TEST WHEN TROUBLESHOOTING THE PRINTER.

The result of the Encoder sensor test is only reported via the serial output and not via the front*panel. To perform the encoder sensor test, move the carriage slightly so that the encoder sensor can detect the change in status. If the carriage is not moved at all, the Encoder Sensor test will always fail. If the carriage is moved and ONLY the Encoder Sensor test fails, then you need to replace the Carriage Assembly￿

If any of the tests fail￿ refer to the individual test documented in this chapter￿
