• Is the media mounted recommended by Mutoh?
If it is not media recommended by Mutoh (especially thin tracing paper, etc.), the paper
sensors may read incorrectly and be unable to recognize the media.
→
Mount recommended media and try again.
• Do paper sensors XF/XR detect normally with the self-diagnostic “Examination/Sensors”?
→
Check the connections of paper sensor F and paper sensor R connectors.
Paper sensor F is the main board connector J101 (XF) and paper sensor R is J108
(XR).
→
Replace paper sensors F and R.
• Check the amount of sensor reflection with the printer's self-diagnostic “Sensor: Edge”.
Check that the difference with and without media is a change of at least "10". Check
using thick coated paper.
→
Check the edge sensor connector.
J204 (PEDGE) on the head board.
→
Replace paper sensors F and R.
• Check the Y cable connectors.
