5.3.3  PF Timing Belt Tension Inspection
This section describes PF Timing Belt tension inspection.
 Purpose 
Confirm that the PF belt tension is proper.
  Things to be used
 Tension gauge
 Plastic Tweezers
 Standard value
 7±1N
 Inspection procedure
1. Move the carriage to the home position.
2. Set the following parameters to the tension gauge:
• Weight: 0.9
• Width: 3.0
• Span: 73
3. Bring the microphone closer to the center of the Timing Belt.  
(See Figure 5-43 (p.235))
4. Press the “MEASURE” button on the Tension gauge and flip the Timing Belt with 
plastic tweezers.

5. Repeat the steps three times and make sure all the measured values are within the 
standard. If not, turn the Spacer around or over so that another letter (2, 4, or 1) comes 
to the upper left, and carry out the measurement again.
Figure 5-44.  Spacer
Bring the microphone within 5mm from the Timing Belt but do not 
let it touch the belt.
 Flip the belt as weak as the tension gauge can measure it.
 Be careful not to damage the Timing belt when flipping it with 
the plastic tweezers.
 Be careful not to let the microphone touch the Timing Belt when 
flipping the belt.
Normally, the Spacer should be 
attached so that the letter “3” on 
it comes to upper left. However, 
if you see a gap between the 
Spacer upper left end and the 
Tensioner, turn the Spacer 
around or over and install it.
