Troubleshooting. Paper transport jam. Transport jam occurred immediately after paper pickup.
| Confirmation Items | Confirmation Tasks | Action at NG |
|---|---|---|
| Check feeding condition | ||
| Paper feeding on the belt | Remove the ID unit, and check whether the paper jam occurred during the route. | Remove the jammed paper. |
| Check the mechanical parts' condition | ||
| Check the sensor lever of the 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 motor operation | ||
| Paper feed motor, belt motor, ID up motor, ID motor | By using the motor clutch test function of the maintenance utility, check whether paper feed motor and belt motor and ID up motor and ID motor operates normally.Check whether the load exists. | As for a paper feed motor, belt motor, ID motor or ID up motor, please replace the main board (M32 PCB) with new one. Replace the paper feed motor or belt motor or ID motor or ID up motor with a new one. Replace ID unit and belt unit with new one. When trying to use a new belt unit, please utilize the fuse keep mode of the maintenance utility. When trying to use a new ID unit, please be careful not to break the fuse with jig inside the ID unit. |
| Paper feed motor driver, ID up motor driver, belt motor driver | Pull the HOP connector of main board (M32 PCB) out, check the following data on the cable side. SEVERAL MΩ Between 1pin-FG SEVERAL MΩ Between 2pin-FG SEVERAL MΩ Between 3pin-FG SEVERAL MΩ Between 4pin-FG Pull the IDUP connector of main board (M32 PCB) out, check the following data on the cable side. SEVERAL MΩ Between 1pin-FG SEVERAL MΩ Between 2pin-FG SEVERAL MΩ Between 3pin-FG SEVERAL MΩ Between 4pin-FG Pull the BELT connector of main board (M32 PCB) out, check the following data on the cable side. SEVERAL MΩ Between 1pin-FG SEVERAL MΩ Between 2pin-FG SEVERAL MΩ Between 3pin-FG SEVERAL MΩ Between 4pin-FG |
As for a paper feed motor, belt motor, ID up motor, please replace the main board (M32 PCB) with a new one. |
| Check the connection | ||
| Paper feed motor cable, ID motor cable, belt motor cable, ID up motor cable, fuser motor cable | Check the cable connection.By visual inspection, check whether incompletely connection and oblique insertion of HOP connector, CID connector, BELT connector, IDUP connector and HEAT connector or defective cable assembly exists. | Assemble normally. Replace the cable with a new one. |
| Paper feed motor cable, belt motor cable, ID up 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. SEVERAL MΩ Between 1pin-FG SEVERAL MΩ Between 2pin-FG SEVERAL MΩ Between 3pin-FG SEVERAL MΩ Between 4pin-FG Pull the BELT connector of main board (M32 PCB) out, check the followings on the cable side. SEVERAL MΩ Between 1pin-FG SEVERAL MΩ Between 2pin-FG SEVERAL MΩ Between 3pin-FG SEVERAL MΩ Between 4pin-FG Pull the IDUP connector of main board (M32 PCB) out, check the followings on the cable side. SEVERAL MΩ Between 1pin-FG SEVERAL MΩ Between 2pin-FG SEVERAL MΩ Between 3pin-FG SEVERAL MΩ Between 4pin-FG |
Replace the cable with a new one, and reassemble correctly |
| Paper feed motor, belt motor, ID up motor | Pull each connector out of the board, and check the following resistance value between terminals on the cable side. HOP connector of main board (M32 PCB) Between 1pin-2pin: about 3.5Ω or 4.4Ω Between 3pin-4pin: about 3.5Ω or 4.4Ω BELT connector of main board (M32 PCB) Between 1pin-2pin: about 3.5Ω or 4.4Ω Between 3pin-4pin: about 3.5Ω or 4.4Ω IDUP connector of main board (M32 PCB) Between 1pin-2pin: about 7Ω or 6.7Ω Between 3pin-4pin: about 7Ω or 6.7Ω |
Replace the paper feed motor, belt motor, ID up motor with a new one. |
