Epson EcoTank ET-7750: Setup, Drivers, Ink and Common Problems

Is the Epson EcoTank ET-7750 right for you?

The ET-7750 is the A3+ sibling of the ET-7700, letting photo enthusiasts print 13x19-inch enlargements from bottle ink for a fraction of cartridge cost. The five-ink dye-plus-pigment system produces pleasing colour but not the archival quality of SureColor pigment printers. Units in regular use for several years commonly reach the waste ink pad limit, and the wide rear feed needs care with heavy paper to avoid skewed feeding and streaks from the head strike.

Best for: Photo enthusiasts who wanted affordable A3+ prints before the ET-8550

Setting up the Epson EcoTank ET-7750

Use Epson Print Layout with ICC profiles for the best A3+ photo results and select the correct media type every time. Join Wi-Fi through the LCD on 2.4 GHz or use Ethernet. Feed A3+ sheets one at a time through the rear slot with the support extended.

1. Unbox and prepare. Remove every piece of shipping tape and packing material, install the ink bottles (fill each tank to the upper line), and load paper in the tray.
2. Join your Wi-Fi. Keep the printer close to the router for setup. Most printers only connect to the 2.4GHz band, so if your router broadcasts one merged network name you may need to split the bands temporarily. See our Wi-Fi guide if it will not join.
3. Install the setup app. Use Epson's official app rather than a driver you found on a search result — third-party driver sites are the most common source of printer malware.
4. Add the printer. On Windows 11: Settings › Bluetooth & devices › Printers & scanners › Add device. On macOS: System Settings › Printers & Scanners › Add Printer.
5. Print a test page and run a scan if this is an all-in-one, so you find any problem now rather than when you are in a hurry.

Ink, toner and supplies

The Epson EcoTank ET-7750 uses the following consumables. Match the number exactly when you buy: the same printer family often uses several different cartridge numbers by region.

• Epson 105 Black (pigment)
• Epson 106 Photo Black/Cyan/Magenta/Yellow ink bottles

High-yield (XL) versions almost always cost less per page if you print regularly. On third-party ink and toner, read our honest assessment first, and note that some manufacturers push firmware that rejects non-original chips.
