Here is the truth the manual won’t tell you: Inside your Epson L3252 is a sponge (the “ink pad”) that absorbs waste ink from cleaning cycles. Epson installs a digital counter. When the counter reaches 100%, the printer self-destructs (locks itself) to prevent ink from spilling.
A "Service Required" message or red blinking lights usually mean the internal waste ink counter has reached its limit. reset epson l3252 better
