Y-Axis Belts Tension Adjustment - Tektronix Phaser 360 Service Manual

Y-axis belts tension adjustment

Perform this procedure after loosening or removing the y-axis belt drive
assembly.
1. Ensure that the three screws that secure the Y-axis drive assembly are
1/4 turn loose.
2. Attach the Y-axis belt tension tool (in its unloaded or folded out
position) to the keyholes in the side frame of the printer just below and
in front of the Y-axis drive assembly. The tool's fishhook should
engage the eyelet of the Y-axis drive assembly.
3. Pull forward and down on the lever arm of the tension tool to apply
tension to the Y-axis belts.
4. While the belts are under tension, rotate the Y-axis motor pulley
10 times to rotate the belts and seat them in place.
5. Beginning with the upper-right screw, tighten the three tension set
screws to 30 in./lbs. to secure the Y-axis drive assembly in place.
6. Release the tension tool's lever arm and remove the tool.
