Star Wheel Lifter test
The Star Wheel Lifter subassembly is designed to move the Start Wheel
support to the up and down positions. This is used to load roll or sheet
media and avoid damage to the Star Wheel caused by paper jams etc.
Perform the Scan Axis - Starwheel lifter test as follows:
1 In the Diagnostics menu, scroll to 1. S c a n A xi s and press OK.
2 The Front Panel will show the 1. Scan Axis submenu.
3 In the Scan Axis submenu, scroll to Star Wheel Lifter and press OK to
start the test.
ALL THE COVER SENSORS ARE DISABLED WHEN IN THE

IF POSSIBLE, ALWAYS PERFORM THIS TEST BEFORE
REPLACING ANY COMPONENT OF THE SCAN-AXIS.
Perform this test with the Printheads and the Tubes System
installed in order to get values that can be compared
correctly.
