How to Fix Epson ET-15000 Fake Paper Jam and Locate the Paper Sensor

Question:
My Epson ET-15000 keeps showing a permanent paper jam error even when no paper is inside. I tried the suggested method, but it still gives me the paper jam message. Where exactly is the paper sensor located that needs to be fed through? I can't see where it is in the video.

Answer:

The "paper jam" error when no paper is present is often referred to as a false jam or fake paper jam. The most common cause is a dirty or misaligned paper sensor.

Here are some key details:

1. Location of the Sensor

   • The ET-15000 uses small optical paper sensors located along the paper path. The one most often responsible for false jam errors is found near the rear feed roller area-just past where the paper enters. It's a tiny plastic "flag" that moves when paper passes through. If this flag sticks or if ink/dust coats the optical eye, the printer thinks paper is jammed.

   • Another sensor can be found closer to the output tray, which confirms paper has fully exited. If either sensor is blocked or dirty, you'll continue to see jam messages.

2. Cleaning the Sensor

   • Use a flashlight to locate the small black plastic lever/flag inside the paper feed path. Gently press it to confirm it moves freely.

   • Clean around the sensor with a lint-free cloth and a small amount of isopropyl alcohol. Avoid excessive liquid, as sensors are delicate.

   • Compressed air can also help to blow away hidden dust or fibers lodged near the sensor.

3. Feeding Through the Sensor

   • When you see technicians "feeding" something through in videos, they are usually pushing a stiff piece of paper, cardstock, or transparency film through the sensor area. This helps dislodge dust or reposition a stuck flag.

   • For the ET-15000, insert a piece of cardstock into the rear feed and slowly push it through until it exits the front. This path will pass through the sensor zone and can often clear the obstruction.

4. If the Error Persists

   • If the printer continues to show a jam even after cleaning, the sensor may be physically damaged or its wiring loose. In those cases, disassembly is required to inspect and potentially replace the sensor. Unfortunately, Epson does not make this easy, as many internal sensors are integrated into larger assemblies.
