se trata de ajustar el valor T2 en el menú de servicio:
Pueden probar a aumentarlo o disminuirlo poco a poco y ver si hay algún cambio por favor. Solo ajustar T2 PWM
• Symptom : gray color spots on the image
• Related units : transfer-related
• Countermeasures: .
Adjust T2 bias // Adjust T2 value in T2 control mode (Service mode)
* PWM + means current/voltage enhancement: useful moisture paper (poor transfer), gray spot
PWM- means current/voltage down : useful high resistance paper,
