How to Locate and Clean the PW Sensor on the Epson WF-2630 Printer

Question

I have a WF-2630 printer and have been experiencing issues after performing a print head cleaning. Several sources, including BCH Technologies, suggested that the PW Sensor might be the problem caused by some absorbing paper towel residue getting stuck on the sensor. I have disassembled the printer to the point where I need to know whether the sensor is on the bottom of the ink cartridge carriage. I have watched numerous YouTube videos, but none show the bottom of the carriage. Some sources claim the photo-optic sensor is underneath, but I am uncertain. Epson tends to change the paper width detection method for each model. Is there a PW Sensor under the ink cartridge carriage on the WF-2630? If so, where are the wires connected, and is the sensor positioned on the bottom left or right of the carriage?

Answer

Regarding your Epson WF-2630 printer issue, yes, a PW (Paper Width) Sensor is located on the bottom of the ink cartridge carriage. To access it, you will need to disassemble the printer thoroughly. Here are the steps:

1. Disassemble the printer and remove the central PF rod.

2. Carefully take out the printhead carriage.

3. Flip the carriage upside down, and you will see the PW Sensor.

It can be unclear since Epson frequently changes how paper width is detected between models. The PW Sensor is typically a small, photo-optic component. A long, thin rag can be gently pulled back and forth to clear any residue. Be cautious not to damage any sensitive parts while doing this.

If you cannot see any wires directly from the position you described, they may be routed through a more concealed part of the carriage. The sensor is usually positioned at the bottom of the printhead carriage, typically near where the cartridges' colors are displayed. Due to model variations, I recommend examining the area thoroughly after flipping the carriage.
