NOTE: Scribing a mark into the outer edge of the Idler Pulley and into the printer
frame, prior to performing step # 4, may help when adjusting the belt tension.

6. Hook a 1000 gram spring scale to the belt as shown in Figure 5-24, and
carefully pull up on the Idler Pulley to increase belt tension.

When a scale reading of 500 grams (± 100 grams) creates a deflection of 1/4

Panel Assembly and Rear Cover.
