When troubleshooting the LJ 5Si, always troubleshoot the error log message. See the LJ 5Si service manual for detailed error log information. X=Location of jam 0=Non-specific jam 1=Paper feed/paper late jam--paper late arriving at PS 2, which is located in the paper pickup unit. Inspect the paper path. Verify flag movement. 2=Paper feed/paper late jam--paper late arriving at PS 2, which is the registration photo sensor. Remove the toner cartridge and lift up the green lever to access the sensor flag. Verify flag movement. 3=Fuser output paper late jam--paper late arriving at PS 1403, which is in the fusing assembly. Verify flag movement. 4=Fuser output, paper jam. 5, 6=Duplex module paper jam. PS 1402 face-down delivery photo sensor is located in the face-down delivery assembly.
