Epson Error 0x73 – FIX

What is 0x73 Error code and how to fix them

This error code is associated with the PW sensor in your Epson printer. You’re probably using Epson P600 and the printer is stuck on the start-up process with this 0x73 error.
The cause for this error is because the PW sensor was triggered when it was not supposed to. It can happen if it detects any jammed paper inside the printer, dust or ink particle in the sensor, or a damaged print head.

It’s very unlikely that it’s a damaged sensor, so it’s probably just being triggered at the wrong time.
Make sure nothing is beneath the print head while performing the initial start sequence, or you will end up with this error again.

    • Hello Mark,
      Thanks for your comment.

      It sounds like the roller that flip the page inside the printer is worn out.
      If it’s printing single-sided paper fine, then the roller that picks the paper and flips it is the problem. The rubber of that roller is probably worn out and needs replacement.

      Hope this helps!
