Tests, Utilities & Calibrations
11. The Printer checks the complete length of the Scan-Axis and displays the result on the Front Panel.
Depending on the printer size, length has to be between:
• 11 5 8 6 2 9 and 1164616 for the 42inch
• 1507858 and 1513844 for the 60inch
If it is shorter, it means that there is an obstacle blocking the Scan-Axis path and the Front Panel will
display a system error code.
If the length is longer, it means that the carriage has a datum broken or the Carriage Stopper is not
installed.
12. The Printer will now check the Scan-Axis PWM and the following information will be displayed on
the Front Panel:
• Starting Scan Axis.
• PWM test.
If there is a failure at this point, the Front Panel will display a system error code.
13 . The Printer will test the PWM at 61 ips and display the results on the Front Panel.
If some of the results are incorrect, the Front Panel will show “High Friction”. Depending on the actual
results received, the following should be done:
• If PWM avg got is more than 32557 and PWM min diff got is less than 3100 then there is high
friction along the Scan-Axis. In this case you should:
• Clean the Slider Rods and Apply Oil along the complete axis of the Slider Rods. After applying
the Oil, perform the test again.
• Check that the Carriage Belt is installed correctly.
• If PWM min diff got is less than 3100 but PWM avg got is less than 32557 then there is a
problem in the Scan-Axis. In this case you should:
• Check that the Encoder Strip is clean. If necessary, clean Encoder Strip using a damp cloth.
• Check that the Ink Supply Tubes and Trailing Cable are installed correctly.
If there is a failure processing the PWM results, the Front Panel will display system error code
86:01. In this case try repeating the test again.
14 . Once the test is completed, OK will be displayed on the Front Panel and then you will be prompted
to press any key to shut down the Printer.
