• Code: E020
• Description: XX=01: Y, XX=02: M, XX=03: C, XX=04: Bk (XX indicates the developing assembly color) XXA0During printing sequence, the difference between the maximum value and the minimum value of SIGNAL (9 samplings) is 0.2 V (10) or less. XX80 During printing sequence, the value of INIT-SIGNAL entered as part of initial settings has dropped to 2.344 V (120) or lower. XX81 During printing sequence, the value of INIT-SIGNAL entered as part of initial settings has risen to 2.656 V (136) or higher. XX90 During printing sequence, the correction value for INIT-SIGNAL has changed to 0 (in service mode, ADJUST>DENS>SIGG-Y/M/ C/K). XX91 During printing sequence, the correction value for INIT-SIGNAL has changed to 255 (in service mode, ADJUST>DENS>SIGG-Y/ M/C/K). XXB0 During printing sequence, the value of SIGNAL obtained by sampling and averaging is 0.43 V (22) or lower. XXB1 During printing sequence, the value of SIGNAL obtained by sampling and averaging is 4.9 V (250) or higher. XXD0During printing sequence, the value of SIGNAL remains higher than INIT-SIGNAL entered as part of initial settings by 4.71 V (240) or more continuously for 10 prints. XXE0 During printing sequence, the value of SIGNAL remains lower than INIT-SIGNAL entered as part of initial settings by 0.98 V (50) or more continuously for 10 prints.
• Causes: The ATR sensor connector is disconnected. The developing cylinder/stirring screw fails to rotate.
