This manual provides detailed instructions for the setup, operation, maintenance, and troubleshooting of your Epson WorkForce ET-4750 EcoTank Wireless Color All-in-One Supertank Printer.

2. Setup Guide
2.1 Unpacking and Initial Inspection
Carefully remove the printer from its packaging. Ensure all components listed in the 'What's in the Box' section are present. Remove all protective tapes and packing materials from the printer's exterior and interior.
2.2 Filling the Ink Tanks
The Epson WorkForce ET-4750 utilizes an EcoTank system, eliminating the need for traditional ink cartridges. Follow these steps to fill the ink tanks:
- Open the ink tank unit cover on the right side of the printer.
- Open the cap for each color tank (Black, Cyan, Magenta, Yellow).
- Uncap the corresponding ink bottle (Epson 502 series). The bottles are designed with unique keys to prevent incorrect filling.
- Insert the ink bottle into the filling port. The ink will automatically start flowing into the tank and stop when full.
- Once the tank is full, remove the bottle and securely close the tank cap and the ink tank unit cover.
- Repeat for all colors.
