How to Install Epson Carriage Scale Timing Encoder Strip

How to Install Epson Carriage Scale Timing Encoder Strip

Today I’m going to be walking you through how to install a timing encoder on your Epson printer. Printers use a timing encoder to tell the printhead its current location. If you find that your Epson’s printhead is skipping some lines, or the printhead seems unable to identify its own location, it’s probably the timing encoder causing the issue.

To get a new encoder, you can go to my website,, and order a new one. You can find them by clicking on the printer parts tab. When you get the timing encoder, you’ll see that they usually have some kind of oil on them. Get some paper towels, warm water, and a small dab of hand soap. Do not use any strong solvents on your timing encoder. Hand soap is mild enough not to cause problems, so gently wipe off the encoder, and you should be ready to go.

Examine the Old Belt

On the older belt, you can see a number on it. The number should be right-side-up and facing you. That way, you’ll know which side is the front and which one is the back. Make sure that it is also facing the right way when you install the new one.

The left side will be spring-loaded, while the right side will be secured with a hook. To unload the spring, you’ll need some kind of hook – you can use a paper clip and bend it into a hook shape. Pull the spring, and you should just be able to release it from the base. Now that the spring is loose, be sure not to lose it.

Now, we can go work on the right side. Pull it gently out of the reader. Once it is no longer threaded through the reader, rotate the left side counterclockwise, and it should come off easily.

To install the new one, make sure you read the numbers to see which side is the front and which is the back. It’s also important that you don’t install it upside down. You’ll see an arrow hear the numbers that should be pointing up and left if you have it facing the right way.

Now all you have to do is reverse the procedure we did to get the old one off. Start by putting the left side on straight and then rotating it clockwise. I find it easier to load the spring before working on the right side.

Now wire the encoder through the readers on your printer. Attach the right side, and you should be good to go.
