Y-axis Belts Tension Adjustment
Perform this procedure after loosening or removing the Y-axis belt
drive assembly. (Refer to Figure 4-4.)
1. Ensure that the three mounting screws that secure the Y-axis
drive assembly to the chassis are one turn loose and that the Y-
axis idler bracket slides freely with respect to the chassis.
NOTE: If there is a situation in which diagnostics are not available
when installing a new Y-axis drive assembly or drum/transfix
assembly, then locate any previously placed index marks on the pulleys
and proceed as if re-using existing parts. Allow the system to cool as
long as feasible before mounting the Y-axis drive assembly onto the
chassis. Tensioning of the Y-axis drive assembly without diagnostics
increases the risk of failures associated with low belt tension (for
example, a “growling” sound heard upon cold power-ups).
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 drum pulley five
times to rotate the belts and seat them in place.
5. Beginning with the upper-right screw, tighten the three
mounting screws to 30 in.-lbs. to secure the Y-axis drive
assembly in place.
6. Using PC-based diagnostics, run the test: “Position for Belt
Tightening” in the “Y-Axis Group” test suite. This positions the
belts in the proper orientation for retensioning. Do not move
the pulleys.
7. Place an index mark on the edge of each pulley: Mark the Y-
axis drive pulley and the drum pulley where the edges are
closest to one another, disregarding previous marks. Use a
distinct color if the pulleys have been previously marked.
8. Loosen the 3 mounting screws until the bracket slides freely on
the chassis and then re-tighten the screws to 30 in.-lb.
9. Release the tension tool’s lever arm and remove the tool.
10. Reassemble the printer and make a test print.
