Introduction
Go to step 1 ↓If the Automatic Document Feeder (ADF) of your Epson ET-3750 is no longer working—for example, because it no longer feeds paper or regularly causes paper jams—you can replace the entire ADF unit.
This guide shows you step by step how to open the device, disconnect the ADF unit cable, and release and replace the ADF from the hinges.
⚠️ During the entire repair, be sure to keep the printer as level as possible to prevent ink from leaking.
