If you are getting a 'carriage jam' error as soon as you turn on your Epson printer with no tasks in progress, then check for any piece of paper stuck in the carriage. Remove the paper carefully. If the paper tears, part of it might remain inside the paper path and damage the product.

Usually, it's caused by carriage error. Turn on printer without ink tank pluged. Then do replacement procedure with pluging ink tank 1 by 1.

hello there. try re-seating the cartridge. Take it out, then put it back in.

The ink cartridge is probably not inserted correctly.  Unplug the printer and manually move the carriage to a location where you can take the ink cartridge out.
 
Remove it and reinsert it, making sure that it is fully located, before applying the power.
 
Make sure that there is nothing blocking the carriage movement, such as some remnant of paper.
 

try to reset the settings in the printer panel inside the printer setup menu. try to choose the initialize all. then observe your printer operation.
