Fixing Epson Workforce 645 Error: Power Off and On Loop Demystified

Question: My Epson Workforce 645 displays the error "Printer Error Turn Power Off and Then On Again," but the printhead doesn’t move. What could be the issue?

Answer:
Typically, the Epson Workforce 645 displays the error "Printer Error Turn Power Off and Then On Again" when it has a serious problem. Unfortunately, it’s not always as simple to fix as one of those paper jams. The generic error is usually indicative of a hardware problem, or poor communication between the different parts of the printer. In order to precisely pinpoint the problem, you’ll need to use specialized software to retrieve the printer’s internal error logs.

Steps to Diagnose the Error:

Use one of Epson Adjustment Program or WICReset:

Epson Adjustment Program will read the error codes or logs for the printer since it is a diagnostic tool. It’s still available to buy on eBay often. The other alternative is WICReset that can be downloaded from the internet. These tools will allow you pinpoint the exact part that is generating the error, be it related to the sensor or printhead or other hardware.

Check for Hardware Failures:

Once you have the error codes, you can figure out the possible defect. Common causes involve a broken sensor, a malfunctioning printhead, or a damaged mainboard. If the printhead doesn’t move, for example, the problem may be with the carriage motor or the encoder strip that keeps track of its position.

Inspect for Visible Damage:

Before you start diagnosing problems with the software, it’s important to inspect the printer’s inner hardware for any obvious signs of damage. This involves checking for loose cables or obstructions, as well as inspecting moving parts such as the carriage assembly for physical wear.
