Star Wheel Assy failure
PG value abnormal
Ink density excessive

Troubleshooting

Step	Check and measure	Yes	No
1	Check the operating environment Check that the operating environment is within the specifications.	Go to step 2	Recommend using in an appropriate environment.
2	Check the paper Make sure appropriate paper has been used. Check that there is no damage to the paper before it pases through. Check that the paper is in an appropriate state (no curling). Check that using suitable paper (not paper already used for printing). * When, for example, A4 paper is used cut to A5 size, the long grain becomes the short grain so there is a tendency for edges to bend easily.	Go to step 3	Use suitable paper. Use the rubbing avoidance mode. * If the symptom continues even after using the rubbing avoidance mode, refer to the avoidance measures.
3	Check the feed path Check that there is no damage to or foreign object on the feed path. Is the result OK? Check that the movement of the flap is smooth (returns to original position due to its own weight after being pushed).	Go to step 4	Remove the foreign object and then clean.. If damaged, contact the Epson Service Support department.
4	Check the points for if bent when duplex printing If bent when duplex printing, compare the conditions with those in the points table.	Go to step 5	Clean the driven roller. You can raise the driven roller a little to make cleaning easier by executing [Settings] > [Maintenance] > [Remove Scraps of Paper].
5	Check the Star Wheel Assy Check that the jagged part of the Star Wheel Assy rotates normally. Check that there are no cuts or other damage locally on the EJ roller surface. Execute the following while looking at the EJ holder/roller from the front when the output tray has been removed. (Execute the following item from the service support mode.) 3020106 PF Motor	Go to step 6	Replace the Star Wheel Assy.
6	Check the PG Is the PG within the specified value range (1.35 ±0.05 mm)?	Contact the Epson Service Support department.	Perform the "PG Adjustment".
Avoidance measures	If the symptom continues even in the rubbing avoidance mode Reduce the print density (default is -20 for duplex, but -5 or -10 from that). Increase the drying time. Make sure that a high density image does not come at the trailing edge of the first side (rotate, change the print order, etc.).
