A printer function fault has occurred, as indicated by this code. There could be many causes for this:
Firmware failures or freezes.
A paper or foreign object jams one of the moveable mechanisms, causing it to bind.
Power outage (for example, a brief power decrease in the network), and so forth.
In most circumstances, the error E01 and Epson printer error code 0xf1 can be resolved by rebooting the printer, which involves turning it off for 10-15 seconds and then turning it back on. You should also look for a paper or foreign object jam in the paper receiving tray.
