Question: I'm trying to set up a brand-new Epson WorkForce WF-3640 printer and it seems there are some weird mechanical issues. It would seem the carriage is not moving freely. This is *before* I get to install the ink cartridges.

The printer may make a loud grinding noise and return errors 0xF1, 0xEA, 0xE8, or 0xE1. Alternatively, the printer may report a paper jam when there is no paper in the paper path at all.

Any ideas?

It seems the carriage is getting stuck on a movable plastic clip at the front right end of the unit or is not engaging correctly at the right end. Why would this be happening?

Answer: 
Epson technical support stated that this is a hardware failure. Standard troubleshooting steps have not produced a solution. 

The printer is being replaced under warranty.

**Update:** The replacement printer has been set up and is fully operational. Well, defective product is defective...
Had 0xF1 and 0x69 errors on our Epson. Solved 0xF1 by discovering the lever on the ink carriage was open and required closing, then rebooting the machine.

0x69 was solved by re-seating the ink cartridges.

Not a good start for a brand new printer.
