[Precautions for Reassembly]
• Align the gear phases when reassembling.
1) Insert the dia. 8 JIG in the alignment hole in the paper drum gear.
2) Align the marking on the intermediate gear with the marking on the paper drum gear before
mounting.
3) Mount the pump gear, confirming that the pump is at the position shown by below sketch.
4) Align the marking on the paper feed intermediate gear with the markings on both the
intermediate gear and pump gear before mounting.
5) Align the marking on the guide gear with the marking on the pump gear before mounting.
• A parallel pin is inserted in the pump gear spindle. This must be aligned with the slots on the pump
gear.
Since the parallel pin is easily detached, care should be taken to keep it horizontal during mounting.
