机型: DC1100/900 4110 4112 4127 主题:如何查找造成77-909的故障代码 问题 : 机器报77-909时,有时候在DC120、DC122里面查不到故障记录 原因: 软件设计 解决: 查看NVM 742-003(链码)和742-004(故障代码)就可以找到造成77-909的传感器代码 然后查手册 找到对应的故障代码,具体解决 E.g.: If the current value in NVM[742-003] is [77] and the current value in NVM[742-004] is [108], it indicates the cause is DC330[077-108]=IOT Exit Sensor. Turning OFF the power clears the values in NVM[742-003] and NVM[742-004]. The suspected sensors are as follows: E.g.: If the current value in NVM[742-003] is [77] and the current value in NVM[742-004] is [108], it indicates the cause is DC330[077-108]=IOT Exit Sensor. Turning OFF the power clears the values in NVM[742-003] and NVM[742-004]. The suspected sensors are as follows: [071-100] Tray 1 Pre Feed Sensor [072-100] Tray 2 Pre Feed Sensor [073-100] Tray 3 Pre Feed Sensor [074-100] Tray 4 Pre Feed Sensor [010-201] Fuser Exit Sensor [077-105] Invert In Sensor [077-106] Invert Path Sensor [077-100] Trans Path Sensor 1 [077-101] Trans Path Sensor 2 [071-101] Feed Out Sensor 1 [072-101] Feed Out Sensor 2 [073-101] Feed Out Sensor 3 [074-101] Feed Out Sensor 4 [077-103] Pre Regi Sensor [077-104] Regi Sensor [077-107] Invert Out Sensor [077-108] IOT Exit Sensor [077-109] Dup In Sensor [077-110] Dup Path Sensor 1 [077-111] Dup Path Sensor 2 [077-112] Dup Out Sensor [075-100] MSI Pre Feed Sensor [075-101] MSI Feed Out Sensor Check the machine inside for pieces of paper. Signal line from the sensor for a short to the frame Check if the Sensor actuator improperly returns. Sensor for light from outside Check for a drop in the power voltage to the sensor. |
