How to Fix Epson ET-2812 Printhead Stuck on the Left with Flashing Lights (Error 0x97 or 0xEA)

Question:
I have a big problem with my Epson ET-2812 printer. When I turn it on, the printhead moves to the left and stops. I already reinstalled the factory software, but the issue persists. Previously, the printhead would move quickly and hit the side, but now it only goes left while the gears keep spinning, and then all the lights turn on. How can I fix this problem?

Answer:

Now, regarding your Epson ET-2812 issue: the symptoms you described-printhead moves left, gears keep turning, and then all lights flash-are usually linked to a carriage return (CR) encoder issue or a sensor alignment problem. These issues are often associated with error codes 0x97 or 0xEA, both of which point to mechanical or sensor-related malfunctions within the carriage system.

Here's a breakdown of what's likely happening and how to fix it:

1. Check the CR Scale (Encoder Strip)
   The CR scale, also known as the timing strip or clear belt, is a thin transparent film with fine black lines that runs behind the printhead carriage. Its purpose is to help the printer determine the exact position of the printhead as it moves left and right. If this strip becomes dislodged, dirty, or not seated properly into the CR sensor (the small reader on the printhead carriage), the printer loses positional feedback and triggers an error-causing the gears to spin endlessly and all lights to flash.

   • Open the top cover and locate the clear strip running horizontally behind the carriage.

   • Check whether the strip passes through the small black reader located on the printhead assembly. If it's above or below that slot instead of inside, carefully guide it through the reader.

   • Make sure the strip is centered and taut between the two anchor points on either side.

2. Clean the Encoder Strip and Sensor
   If the strip is correctly seated, it might still be dirty. Even a small amount of ink mist or grease can confuse the optical sensor.

   • Power off and unplug the printer.

   • Gently wipe the strip with a lint-free cloth slightly dampened with isopropyl alcohol (at least 90%).

   • Avoid pulling or stretching the strip. Let it dry completely before powering the printer back on.

3. Inspect for Obstructions or Mechanical Lock
   Sometimes the printhead can't move freely because of dried ink, paper fragments, or a jammed gear in the carriage path.

   • Move the carriage manually (with the printer unplugged) and check for resistance.

   • Remove any obstructions, and ensure the carriage can glide smoothly from side to side.

4. Recheck the Carriage Cable and Gear Mechanism
   If the gears continue to spin after the printhead stops, the drive belt or gear train may be slipping. Inspect the drive belt for wear or damage. In rare cases, a worn motor pulley can cause the system to over-rotate and trigger an error.

5. Reset and Test
   After reseating and cleaning the CR scale, plug in and restart the printer. If the printhead moves freely and the lights stay off, the problem was successfully fixed.

If the issue persists even after verifying the encoder strip and cleaning the sensor, it could indicate EEPROM corruption or carriage motor failure-both of which may require advanced repair or replacement.

Addressing printer issues can be a complicated affair due to the hands-on nature of the problems. Therefore, we're not able to provide remote troubleshooting, suggestions, or support for printer repairs. We do offer an in-person evaluation and repair service via our local diagnostic facility (https://bchtechnologies.com/printer-repair-service). Given the high demand, our service operates on a first-come, first-served basis and may take a few weeks before your printer can be dropped off. We handle both complete printer repairs and individual part replacements, with clear guidance provided along the way. While our rates may not be the lowest, we strongly encourage self-help through online resources. You can start by visiting our YouTube channel (https://youtube.com/@bchtechnologies). Use the search icon next to the "About" section to look for specific videos-we've built an extensive library over the past nine years that covers most repair topics.
