@ecooney try to check those things systematically. Start with what Epson suggest:
Poor Paper Loading
[Presumable Cause]
• Use of 3rd party media
• Edge guide mis-setting
• Foreign material
• Part come-off
• Contamination of paper feed roller on Pickup Roller or Duplex Unit
• Paper Casette Assy damage
• Contamination of PF Roller
[Major Troubleshooting]
• Recommendation of EPSON media
• Edge guide re-setting
• Foreign material removal
• Part re-installation
• Pickup Roller replacement
• Duplex Unit replacement
• Paper Casette Assy replacement
• Printer Mechanism replacement
Paper Jam Error
(Occurrence Condition]
This error occurs when top/bottom of paper is not detected by ASF PE Sensor or PE Sensor in the specified steps of paper loading / ejecting operation correctly.
[Major Occurrence Timing]
• Power-on timing
• Paper loading timing
• Paper eject timing
[Major Troubleshooting]
1 Push "Start" button after the jammed paper in printer mechanism is removed.
2 If this error occurs again, check foreign materials / parts come-off / parts damage / parts
deformation in paper path.
3 If this is not solved by 2), check the following parts.
• ASF PE sensor (Paper Guide Rear ASF Assy)
• PE sensor
• Main board
