Service Checks and Adjustments
Carriage Drive Belt
Service Check
1. Power off (O) the printer.
2. Remove the ribbon cartridge. See “Ribbon” on page 353.
3. Move the printhead to the right side stop.
4. Using a push-pull scale (such as IBM P/N 460870) to check the belt tension, apply pressure to the upper half
of the belt (at a point midway between the printhead and the left side frame) until it begins to touch the bottom
half of the belt. To accurately measure the tension, it is critical for the raised surfaces of the teeth to align, as
shown in Figure 51.
The correct force required to bring the top of the belt into contact with the bottom of the belt is 0.9 ±0.05 kg
(2.0 ±0.1 lb).
5. If the measurement is correct, the service check is complete. Stop here and return to the step that sent you
here.
If the measurement is not correct, go to the adjustment.
