What is PIS sensor and what does a PIS sensor do?
PIS Sensor. Some people call it "Photo Ink Sensor". It is an analog proximity sensor that measures the reflection of infrared from objects. According to Kevin, Epson's A2140859 sensor board has a capacitor to clean out the input, then the rest of data can be found by looking at Sharp GP2Y0A21YK. If your printer's PIS sensor is broken, it will throw non-recoverable errors during start up. However, the sensor can be easily replaced.
Before ordering it, make sure the model number matches the A number on the back (see photos above). This sensor board is widely used in WorkForce (WF), Expression Home (XP), and other series. Because the board is so simple, just a sensor and a capacity, as long as it fits in your printer, you can try it even your model number doesn't match (no gurantee). Therefore, we included detailed measurements (see photos) in case you want to try to replace a different model.

Kevin is definitely on the consumer's side. Very helpful in pushing back against big corporate greed when it comes to everything printer related. Thank You Kevin!!

Have enjoyed learning from Kevin and the team like Abbey. Apologies if I butchered the names. I actually have driven past their location without realizing what it was in some years back. Currently not close enough to stop by but really appreciate the knowledge and sharing you all provide, not to mention services such as my current purchase. Thank you again. Respectfully, J.

Kevin is the best at BCH. I had no clue what I needed, so I sent a picture to BCH and within 30 minutes, I had a response from Kevin, during off hours if I recall right. That's a big plus for a quick response! Kevin was able to identify my needs from the picture sent. I ordered the parts and within a few days, I received my items. All items were correct and packaged well. This was my second order with BCH and will not be my last. I love the great customer service with the great packaging of their products. Quality products! Quick Delivery! Excellent Customer Care! 5 stars! (at the least) Thank you, BCH!!
