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: 
### 0xE8 and later 0xEA codes

### 520 FATAL CODE:0xF1 EPSON Workforce

I had a plastic carriage on the one side that was stuck in a position that stop the carriage from make the complete run from side to side. When I forced the plastic carriage down and it clicked into place the error stopped and the printer started up normally with no codes.

Same error code 0xEA for WF-3640 received today.

...multiple attempts to clear it, but each time (after I finally got the carriage to go to the left), the carriage returned to the right, locked up, and error'd out.

Called Epson...cycled through the same process, even sent them a picture of the l-shaped bracket (for whatever they needed to look at)...tried again, and...surprise the same error occurred. They finally stated "hardware error", please return it to the place of purchase for a replacement. This is the first Epson in 20+ years...have had nothing but Canons and first one out of the box...it's really a shame. Hopefully the warranty replacement will be happier.
