5.2.14 Front Belt Removals
Refer to Figure 5-18, and proceed as follows:
Step 1. Swing down the Front Panel (see Section 5.2.1).
Step 2. Loosen the screws holding both Idler Pulley Brackets.
Step 3. Replace the timing belt(s). Note that the belt on the right requires removal to
replace the belt on the left.
Step 4. Take up the belt slack by swinging the Idler Pulley(s) against the associated
belt. Then tighten the associated Idler Pulley Bracket screws. Note that with too
much belt tension, the Stepper motor stalls. Therefore, make the belts slightly loose
rather than too tight. Note that for precise settings, belt tension fixtures are
available (see Section 6.3.6).
