Description: K ID sensor error While the LED is off, the ID sensor output does not meet the standard voltage (between 0.05 V and 1.5 V).
Causes: When the output meets the standard voltage: MCU, harness When the output does not meet the standard: K ID sensor
Code: 104
Description: ID sensor output error (rough adjustment) The difference in ID sensor outputs when the transfer belt is read and when the LED is off does not meet the standard voltage (Vbkcal±0.4 V).
Causes: K ID sensor, MCU, transfer belt error, transfer belt surface unevenness, incorrect ID sensor installation
Code: 105
Description: ID sensor output error (fine adjustment) The difference in ID sensor outputs when the transfer belt is read and when the LED is off does not meet the standard voltage (Vbkcal±0.1 V).
Causes: K ID sensor, MCU, transfer belt error, transfer belt surface unevenness
Code: 110
Description: ID sensor pattern error (Cyan) The slope gM of the line representing the relationship between the C development bias and attached toner amount is not between –0.01 and – 0.0005.
Causes: Incorrect color DTM installation, incorrect PCU installation, development bias error, MCU, LD control malfunction, loss of synchronization
Code: 111
Description: ID sensor pattern error (Magenta) The slope gM of the line representing the relationship between the M development bias and attached toner amount is not between –0.01 and – 0.0005.
Causes: Incorrect color DTM installation, incorrect PCU installation, development bias error, MCU, LD control malfunction, loss of synchronization
Code: 112
Description: ID sensor pattern error (Yellow) The slope gM of the line representing the relationship between the Y development bias and attached toner amount is not between –0.01 and – 0.0005.
Causes: Incorrect color DTM installation, incorrect PCU installation, development bias error, MCU, LD control malfunction, loss of synchronization
