I consulted with LPS representatives about the error code and they recommended replacing the Encoder Sensor. I replaced the sensor but not the disk as that is more involved and the machine has worked ever since. Thanks LPS!

Nice to see Maggie

It worked, came with all the necessary parts and fit perfect. I would recommend an would purchase again.

Always answer the phone, very thorough, very helpful

I have a photo electric engineer friend who told me that the sensor is the most likely at fault because the disk let’s light through or not. I cleaned the disk on each side with w tip with little alcohol. Bugs like that spot. Q tip had black marks after the clean that requires someone to manually rotate the roller from underneath the disk is hidden and very hard to see the use of a flashlight is needed. Uninstall the sensor by unscrew from case remove the spetoon 3 mm to the left an integer back to front then up and out. I didn’t change the cable for it didn’t look bad or had any damage.make sure that the disk slides through the sensor it has a gap as it rotates infra red can pass or be abstracted. Upon installation run the print head alignment. Enjoy for years to come. Get the disk even if you don’t install better to have it rather wait thanks your company gave the best support ever
