FUSING SECTION
After Replacing Hot Roller or Pressure Roller
Rough Adjustment
1. Execute SP1914 001 (set to On) to
ensure that the pressure motors [A]
are at the home position.
2. Measure the length of the spring [B]
with calipers.
Correct spring length:
Outside
28.8± 0.3 mm
3. If the spring length is longer or
shorter than the correct
measurement, adjust the position of
the home position sensor [C].
Move sensor:
Toward the motor
Away from the motor
4. Measure the spring length again with calipers to confirm that it is correct.
Fine Adjustment
During normal operation the spring, bracket, and sensor move out of the home
position to the correct position determined by automatic software calculations for
the paper type, fusing mode setting, and fusing roller temperature.
The following SP codes can be used to select the pressure control correction
settings if skewing occurs after changing the paper length selection.
SP1914 002
Right Pressure Adjustment
SP1914 003
Left Pressure Adjustment
Changing these SP codes does not change the position of the bracket and sensor
immediately after adjustment. The position is adjusted only during copying.
If these SP codes are adjusted, the settings must be the same size but of opposite
sign. Example: Right Pressure +1 / Left Pressure –1
[A]
To make the spring:
Longer
Shorter
3-48
