In trying to Execute carriage change sp mode (3-009-002), I cannot find 'Engine setting' (which according to the service manual) supposed to be under 'Printer setting' menu from Service mode.
Can someone help on step-by-step procedure of getting to the "Engine Setting" (sp mode) menu please in case am omitting something along the line or is their a permission required?

Image transfer belt overrun sensor (rear) - these can become sticky as they are above the fuser - to clear the error physically move the belt towards the front of the machine away from the sensor. line up with black lines on bed of intermediate transfer blades' assembly make sure all rollers are clean and located correctly it is ok to turn the belt around to see if that helps
