Manual Sensor Adjustment for Fuji SP500

[Travis]

Hello, 

 

I just bought a 135 Bobach Mask and have installed it as instructed and even did the Axis Optical Adjustment. However, the area being captured by my sensor is not precise and I will need to adjust the sensor by hand. Can anyone share which manual it is or chapter, as I cannot find anything related to this in the servicing manual. 
 

please find attached a shoot of my adjustment and you can see that I need to adjust the sensor. I am able to PayPal for expert advice, thank you.
