The ID sensor output voltage is 5.0V and the PWM signal input to the ID sensor is 0 when checking the ID sensor pattern.įor 2 s during the ID sensor pattern check, the ID sensor pattern edge voltage is not 2.5V or the pattern edge is not detected within 800 ms. ID sensor pattern not written correctly.One of the following ID sensor output voltages was detected twice consecutively when checking the ID sensor pattern. Development bias leak due to poor connection, defective connector.The high voltage applied to the development unit is detected 10 times higher than the upper limit (45%) of PWM.

Description: Development output abnormal.

TD sensor connector disconnected or defective.

Switching the machine off and on will cancel the SC display, but does not release ID sensor toner supply. Note: This SC is released only after correct adjustment of the TD sensor has been achieved. When this error occurs, the display of SP2-906-1 reads 0.00V.

Description: TD sensor adjustment error 2ĭuring the TD sensor auto adjustment, the TD sensor output voltage (Vt) does not enter the target range (3.0 ± 0.1V) within 20 s.
