Troubleshooting. Paper Feed Jam (Multipurpose tray)
Paper jam occurred immediately after turning on the printer. (Multipurpose tray)
Confirmation Items | Confirmation Tasks | Action at NG |
---|---|---|
Check paper-feeding route condition | ||
Paper-feeding route inside the multipurpose tray | Check whether the paper jam occurred during the route. | Remove the jammed paper. |
Check the mechanical parts' condition | ||
Check the sensor lever of the entry sensor 2 and WR sensor. | Check whether there is something abnormal about the form of sensor lever and its movement | Replace the sensor lever with a new one. |
Check the electrical parts' condition | ||
Check the condition of sensor signal detection. | By using the switch scanning test function of the maintenance utility, check whether the sensor signal has been normally detected. | Replace the main board (M32 PCB) or front sensor board (MIP PCB) or the connecting cable with new one. |
Check the output level of entry sensor 2 and WR sensor | Check the following signals of FSNS connector of PU board (M32 PCB). 2pin: WR sensor 3pin: entry sensor 2 Operate and adjust the sensor lever in order to check the above signal level. |
Replace the front sensor board (MIP PCB) with a new one. |
Check the power supply of front sensor board (MIP PCB). | Check the power supply of 5V of CN connector of front sensor board (MIP PCB). 1pin: 5V power supply 5pin: 0VLConfirmation Items |
Replace the connecting cable with a new one. Confirmation Tasks |

Check the sensor lever of the entry sensor 2 and WR sensor. | Check whether there is something abnormal about the form of sensor lever and its movement. | Replace the sensor lever with a new one. |
Front cover | Check whether the left and right lock of front cover has been locked normally.Confirm both right and left locks of the front cover work well. | Replace the front unit with a new one. |
Check the motor operation | ||
Paper feed motor | By using the switch scanning test function of the maintenance utility, check whether paper feed motor operates normally. | Replace the main board (M32 PCB) or paper feed motor with new one. |
Paper feed motor driver | Pull the HOP connector of main board (M32 PCB) out, check the following data on the cable side. SEVERAL MW Between 1pin-FG SEVERAL MW Between 2pin-FG SEVERAL MW Between 3pin-FG SEVERAL MW Between 4pin-FG | Replace the main board (M32 PCB) with a new one. |
Check the connection | ||
Paper feed motor cable | Check the cable connection.By visual inspection, check whether incompletely connection and oblique insertion of HOP connector of main board (M32 PCB) or defective cable assembly exists. | Connect the cable normally.Replace the cable with a new one. |
Paper feed motor cable | Check whether wire gnawing occurred during assembly of equipment.Pull the HOP connector of main board (M32 PCB) out, check the followings on the cable side. Short circuit between 1pin-FG Short circuit between 2pin-FG Short circuit between 3pin-FG Short circuit between 4pin-FG |
Replace the cable with a new one and reassemble correctly. |
Paper feed motor | Pull the HOP connector of the main board (M32 PCB) out, check whether the resistance values between 1pin- 2pin and 3pin-4pin are about 3.5W or 4.4W respectively. | Replace the paper feed motor with a new one. |
