Check the wire of Paper Gate Sensor. 2. If the wire has no problem, replace the Paper Gate Sensor with the new one.

• Code: J-00000002
• Description: Jam at Paper Deck 1
• Causes: 1. The Roll Paper Set Sensor Signal (RPSET1) does not change from H to L within a specified time since the machine has started feeding. 2. The Roll Paper Set Sensor Signal (RPSET1) does not change from L to H within a specified time since the machine has started rewinding.
• Remedy: Setting condition of roll paper 1 Is the roll paper in the 1st Roll set properly? No Set it properly.
  Paper Set Sensor 1 (PH1A) 2 Check the status of Paper Set Sensor (RPSET1) in Input Check. (Signal Code: 0050h) Is it “L” when the roll paper is set? NOTE Refer to [8.6 Input Check]. No 1. Check the wire of Paper Set Sensor 1. 2. If the wire has no problem, replace the Paper Set Sensor 1 with the new one.
  Roll Feed Sensor 1 (PH2A) 3 Check Clock Signal of Roll Paper (RPCLK1) using Input Check. (Signal Code: 0051h) Does signal change “L” and “H” alternately, while Roll Paper is fed?
