7. The Carriage will be moved to the middle of the Center Platen. If there is a failure in moving the
Carriage, the Front Panel will display system error code 01.0:10 ⇒ page 78.
8. The printer will now check that it can read the Encoder Strip. When the following message displays
on the Front Panel, open the Window and press the Up key to move the Carriage to the left and the
Down key to move the Carriage to the right. Make sure that you move the Carriage in both
directions and check that the Carriage actually moves when a key is pressed.
If there is a failure at this point, the Front Panel will display system error code 01.0:10 ⇒ page 78.
If the Carriage only moves in one direction, troubleshoot the problem as system error code 01.1:10
⇒ page 78.
9. At the end of 10 Carriage movements, the Front Panel will display the maximum and minimum
length (in encoder units) of the 10 movements and the overall average.
If Carriage movement has not been detected or if Carriage movement was very short, the Front Panel
will ask you “Did the motor move?”. If the answer is Yes (the Carriage had moved) press OK. If the
answer is No (the Carriage had not moved) press the Back key.
If you select No (the Carriage had not moved), the Front Panel will display system error code 42:10
⇒ page 102. Check also system error code 01.1:10 ⇒ page 78 or system error code 01.0:10 ⇒
page 78.
If you select Yes (the Carriage had moved), the Front Panel will display a system error code. Check
also system error code 11 : 10
⇒ page 81 or system error code 01.0:10 ⇒ page 78.
If any max. or min. movement length is outside the ±20% average, then this warning message will
be displayed on the Front Panel “Some movements out of avg. ±20% range: Intermittent movements.
PWM test needed”. This warning means that there is a mechanical problem in the Printer (Encoder
Strip, friction, Carriage Belt, Slider Rod, etc...). Press any key to continue with the PWM test.
10. The Printer will now start to initialize the Scan-Axis servo and the Front Panel will display the
following information:
• Starting Carriage Motor.
• Off/On Carriage Motor.
• Doing a right side bump.
• Doing a left side bump
• Exit bump position.
If there is a failure at this point, the Front Panel will display system error code 86:01
⇒ see
page 114.
