5.3.1.1 PF Belt Tension Adjustment Method
Proper measurement may be interrupted by sounds picked up from
C A U T I O N
around. Make measurement in silent environment.
1. Secure the PF Motor to the Printer Mechanism, and install the Drive Belt on the
Gear of the PF Scale and the Pinion Gear of the PF Motor.
2. Press the [POWER] button. The LCD of the Measuring Tool displays No. 0 and
No. 1.
3. From among No. 0 to No. 9, select the channel you want to store its setting by
pressing the [SELECT] button. The initial value may be selected as the channel.)
4. Press the [WEIGHT] button. The initial value will be displayed. Type the ten-key
pad so that "1.2g/m" is displayed.
5. Press the [WIDTH] button. The initial value will be displayed. Enter "5.0 mm"
with the ten-keypad.

As the Drive Belt is flipped with the tip of tweezers in the following
C A U T I O N
steps, carefully choose the flipping position so that the Belt will not
make contact with the Microphone by reaction of flipping.
8. Press the [MEASURE] button. ("----" is displayed on the LCD screen.)
9. Put the tip of the tweezers on the Drive Belt, and flip it downward in that position.
The "----" displayed on the LCD will become wave pattern during the
measurement. When it has finished, the measurement result will be displayed by
"N" (Newton) after the beep. This jig can pick up and measure sounds accurately,
regardless of the flipping force.
10. Repeating 8 and 9, delicately shift the variable part of the PF Motor mounting
position to adjust the tension until the tension falls within the allowable standard
value.
Standard Value: 10.5 ± 2N (8.5 ~ 12.5N)

 Even if the Timing Belt is flipped, the LCD screen may not
C A U T I O N
change at all. In this case, flip the Timing Belt again after a few
seconds have passed.
 If measurement results differ greatly from each other, acoustic
sounds may not be picked up properly in any of the
measurements. Therefore, flip the Timing Belt again with the
tweezers, and record the value at which two measurement
results are approximate. Displaying errors in the range 1/100 to
5/100, the Measuring Tool has high reliability.
