How to Replace Encoder Sensor
There are four or five cables at all printer or machine Encoder Sensor. These four cables must be connected to printer head board correctly.
- Encoder Sensor Gnd Ground Cable ⇄ must be connected to printer head board Ground Line. Most of head board Ground Line is located at the one end.
- Encoder Sensor Vcc Power Cable ⇄ must be connected to printer head board Power Line. Power is DC 5V. Most of head board Power Line is located at the other end. But you should double check Power Line to make sure. Otherwise the RED LIGHT at the encoder sensor cannot be ON.
- Even wrong connection can not burn your head board because this power line is just DC 5 V. That’s why you can test your cable connection is correct.
- Encoder Sensor chA Direction Cable ⇄ must be connected to printer head board A Line. This line controls printer moving direction A (Right or forward). It’s OK if you connect chA and chB wrong first time, and just switch chA with chB.
- Encoder Sensor chB Direction Cable ⇄ must be connected to printer head board B Line. This line controls printer moving direction B (Left or backward).
- Q=180, P=150, 1=360 and 2= 300.
How do you know your encoder sensor is connected correctly?
Just turn on your printer and connect your encoder sensor Ground Cable [Gnd] and Power cable [Vcc] to two ends. if red light is ON and that prove your encoder sensor power cables were connected successfully.
Then connect your encoder sensor two DIRECTION cables [chA] [chB] to the two middle cables at the printer head board. Then turn on your printer and move printer head with printer control software. If you can move head LEFT and RIGHT correctly and that can prove you successfully install encoder sensor.
If you cannot move LEFT or RIGHT correctly. that proved your encoder sensor DIRECTION cables were connected wrong. Just switch [chA] with [chB] and then encoder sensor will be OK.

How to clean Printer Encoder Strip
How to clean Epson Printer Encoder Strip? Agfa. Colorspan. Epson. Gerber. Fujifilm. HP. Maxjet. Mimaki. Mutoh. OCE. Ricoh. Roland. Seiko. Skyjet. Teckwin. VUTEk. Xerox. You will need Isopropyl Alcohol, Cleaning Swabs and Paper Towels. Putting two drops of alcohol onto each side of the cleaning swab. Dab the swab on the paper towel to soak up any excess liquid. Wipe the exposed area of the Epson Printer Encoder Strip strip gently in one direction, do not try to scrub the strip or bend it. Repeat the cleaning for the back of the Epson Printer Encoder Strip strip. Put the machine into Cleaning Mode under the Maintenance Sub-Menu. You will now be asked to remove the maintenance cover on the left side of the printer. After the Head Carriage moves to the left side of the printer, continue to clean the area of the Epson Printer Encoder Strip strip that is now exposed over the docking area. Once the Epson Printer Encoder Strip strip has been cleaned, perform a Limit Initialization to reset the Head Carriage. All printer manufacturers use optical Epson Printer Encoder Strip in inkjet printers to tell the print head carrier how for it has moved and also when it return to home position. If you get a bad printer jam hat blocks the carrier this Epson Printer Encoder Strip strip can get disconnected and then the printer can not print anything. We are about to show you how to repair the strip if it is damaged and reinstall it so the printer can function again. This guide uses the Roalnd Printer as an example but the steps are the same for any printer that uses these Epson Printer Encoder Strip strips. The first thing to do is check the strip for damage. Check both ends and make sure the plastic is not torn. The ends should have an opening about 1/4 inch from the end as seen here. If your Epson Printer Encoder Strip strip is torn you can usually repair it with packing tape. Wrap the tape around the end several times and the use a small knife to cut the tape where the original hole was as seen below. Then cut the tape off the strip around the side and end. Now its time to reinstall the strip. The Epson Printer Encoder Strip strip attaches to retainer brackets and both sides of the printer and is threaded through the printhead carrier in the middle. You will need the carrier to be in the middle of the printer. To get it there you will need to power up the printer and open the cover like you were going to change the print heads. Power up the printer and the print heads should start to move to the side. When they get about the center of the printer you will need to pull the power plug so they stop moving. Connect one end of the Epson Printer Encoder Strip strip as seen here. Now thread the Epson Printer Encoder Strip strip through the carrier as seen here. The outside opening is about 1/2 inch but the slot the encoder goes in is only about 1/16in so be patient. Then connect the other end of the Epson Printer Encoder Strip strip. the left hard side is spring metal to tension the strip and keep it tight. Now if you reapply the power to the printer the carrier should move freely and move back to the right side. Close the printer cover and try a test print to see if it work. If you still get a carrier jam then the strip did not get inserted correctly through the carrier. Just disconnect it and try again.
