The Epson 1390 printer is a reliable model, but like any machine, it has quirks. One of its most common issues is overheating the capture return motor (CR motor). Whether replacing a faulty motor or looking to prevent future issues, this guide will walk you through selecting the correct motor for your printer and provide tips for extending its lifespan.
We also have a video below to show you exactly how it's done so you can follow along visually.
Understanding the Common Issue: Overheating Motors
The Epson 1390 printer is notorious for overheating its CR motor. This is a frequent problem due to the design and the workload the motor handles. While some users might be tempted to buy any motor replacement labelled "compatible," it's important to know that not all motors are created equal. Using the wrong motor can lead to inefficiencies, slower performance, or even damage to your printer.
To combat overheating, you can install a heatsink. BCH Technologies offers heatsinks explicitly designed for this purpose. Connect the heatsink to a 5-volt adapter, and you'll have a preventative solution that could save your motor from future failure. Many users have reported excellent results, with their motors lasting years longer than without this setup.
Recognizing the Differences Between Epson Models
Before diving into the replacement process, it's essential to understand the physical and functional differences between motors from different Epson models, such as the 1390 and the L1800.
- Cable Differences: The 1390's cable tends to be smoother and more reddish, while the L1800's cable is rougher and yellowish.
- Drive Gears: The 1390 motors typically have a double-ring gear design, differentiating them from the L1800's single-ring gear.
Selecting a motor that matches these specifications is crucial for optimal performance. Even if it fits, using an engine designed for another model could lead to poor functionality or premature failure.
Where to Source Reliable Motors
Finding a genuine 1390 CR motor can be challenging. Unfortunately, most "new" Epson 1390 printers are refurbished models, so their parts may not be entirely new. Sourcing motors from reputable suppliers ensures you get the right components.
Tips for Finding a Motor:
- Avoid Generic Listings: Many listings on platforms like eBay or AliExpress label motors compatible with multiple models, but they often lack the necessary specifications.
- Look for Double-Ring Gears: Genuine 1390 motors have a distinct double-ring gear design, which ensures compatibility and performance.
- Check for Long Cables: Some versions of the 1390 motor come with longer cables, which are essential for proper installation.
BCH Technologies currently stocks heatsinks for CR motors. If there is enough demand, they may consider carrying 1390-specific motors. For now, searching AliExpress with a critical eye is your best bet.
Spotting Fake or Mismatched Motors
Not every motor claiming to be compatible with the 1390 will work. It's easy to fall into the trap of purchasing a motor based solely on price or a vague compatibility claim. Below are some common pitfalls to avoid:
- Short Cables: Motors with shorter cables often belong to other models and may not connect properly to your printer.
- Incorrect Gears: Many motors feature gears that are too large or too small for the 1390s' design.
- Misleading Listings: Some sellers group multiple models under one listing. Always verify the motor's exact specifications before purchasing.
When in doubt, compare motors visually. Look for specific markings such as "RS-455ST" or manufacturing details like "Made in Vietnam," as these can indicate genuine parts.
Preparing for Installation
Once you've acquired the correct motor, it's time to prepare for installation. Here are a few tips to ensure a smooth process:
- Gather Tools: You'll need a screwdriver, pliers, and a multimeter to test connections.
- Inspect the Motor: Before installing, check the motor for any visible defects or irregularities, such as bent pins or damaged gears.
- Test Before Full Installation: Connect the motor temporarily to confirm it functions correctly before completing the installation.

The Case for Preventative Maintenance
Even with the correct motor installed, it is wise to invest in preventative measures to extend its lifespan. Overheating remains the most common culprit for motor failure, and adding a heatsink is an affordable way to mitigate this risk.
BCH Technologies offers heatsinks explicitly designed for the Epson 1390 CR motor. These heatsinks are easy to install, requiring only a simple 5-volt adapter. Many users report that motors equipped with a heatsink last significantly longer than those without.
Final Thoughts on Sourcing and Maintaining CR Motors
Selecting the correct motor for your Epson 1390 printer can be daunting, but understanding the specific requirements and common pitfalls will make the process much smoother. Always prioritize quality over cost; the right motor can save time and money.
Preventative maintenance, such as using a heatsink, is a simple yet effective way to extend the life of your motor and improve your printer's overall performance. Visit BCH Technologies to explore solutions that can help keep your printer running smoothly for years.
