While there are many 3rd party power
supplies out here with comparable specs for less money, however:
We have found that these power supplies don’t often deliver what they
say, leading to printer outages, and (more inscrutable), intermittent
printer errors. Thermal printers require peak power from the supply when
printing at maximum speed ,and certain interfaces, especially Ethernet
and wireless, have significant power needs. Clone supplies often don't
have adequate headroom to deliver.
Use the right power supply for the printer and be wary of unknown 3rd
party supplies that may or may not deliver what they say. Buy new or
refurbished Epson power supplies to be sure.
