Product Overview

The WorkForce ET-3750 and ET-4750 all-in-one printers are two of the seven devices recently introduced in Epson’s portfolio of EcoTank Supertank all-in-ones. The EcoTank printers has a unique feature of providing cartridge-free, easy-to-use ink tanks that has enough ink to last for two years. The printers are shipped with two black ink tanks and two of each of the three color ink tanks with a maximum print yield of 14,000 pages (black) and 11,200 pages (color). That’s very remarkable and goes a long way to helping small businesses save on print costs.

Epson has improved on its EcoTank system, making it easy for the user to refill ink rather than replace cartridges. The ink tanks on each printer is located on the front. Each ink bottle includes an auto-stop feature that indicates to the user that the tank is full, which prevents inaccurate ink fillings.

The WorkForce ET-3750 ($400) and WorkForce ET-4750 ($500) includes standard printing, copying and scanning features. Both printers include an ISO speed of up to 15ppm in black and up to 8ppm in color. They’re powered by Epson’s PrecisionCore technology. PrecsionCore uses a high-density print chip that can generate up to 40 million precise dots per second.

The ET-3750 and ET-4750 share many similar features, however, there are a few differences. First, while each device includes a 2.4″ color LCD display, the ET-4750’s display has a touchscreen interface. Also, both devices has different paper input capacities: the ET-3750’s capacity is 150 sheets and the ET-4750’s capacity is 250 sheets. Finally, the ET-4750 includes standard faxing functionality.

Both devices are available in retailers, such as Amazon, Staples, Office Max, and Office Depot. They’re also available directly on Epson’s site.

More details on each device is in our Features section below.

The Workforce ET-3750 and Workforce ET-4750 are affordable buys for small businesses that only need basic but strong multifunctional features. The extra ink tanks shipped with the printer goes a long way in helping businesses save on printing expenses.


Both the WorkForce ET-3750 and WorkForce ET-4750 include host-based printing (Epson’s proprietary printing language). USB, Ethernet and Wi-Fi connectivity are standard. Mobile printing is supported via Epson Connect, Epson Email Print, Epson iPrint Mobile App, Epson Remote Print, Apple AirPrint, Google Cloud Print and Mopria Print Service.

As mentioned above, the paper input capacity is 150 sheets on the ET-3750 and 250 sheets on the ET-4750. The output capacity is only 30 sheets. There is also a 30-sheet automatic document feeder.

Paper size ranges from 3.5″  x 5″ up to 8.5″ x 47.2.” There is a 5,000-sheet monthly duty cycle, but Epson recommends a monthly volume of 800 pages.

Copying speed is up to 11cpm ISO in black and 5.5cpm ISO in color. Standard copying features include duplexing, ID copy and adjustable copy density.

The scanning function uses the color flatbed CIS scanner. It supports scan-to-PC (via Document Capture Pro), scan-to-Cloud and scan-to-PDF.

The faxing function (on the ET-4750) includes a 33.6kbps modem. Standard memory is up to 100 pages. PC faxing is supported.

Both devices are Windows and Mac compatible. There is a two-year limited warranty.

As mentioned above, the printers shipped with two black ink tanks and two of each of the three color ink tanks with a maximum print yield of 14,000 pages (black) and 11,200 pages (color). The yields for the replacement bottles are 7,500 in black and 6,000 in each color. Based on our calculations, the cost per page in both black and color is roughly a penny. Businesses will not only save money by using the initial ink tanks but also on the replacement ones.

The company has been an innovative designer of ink jet printers and sells an extensive product line. Most of these are geared to home and school use, but Epson continues to extend its line further into the office environment.

Epson has been making a more aggressive play for the document scanner market, although the company’s been in the multipurpose office scanner business for years. The models and other additions to its model line seem to be part of an effort to further extend its current scanner technology. As part of this effort, Epson makes these scanners available in consumer electronics stores such as Best Buy, along with Epson dealers and on its website.

ET-4750 has been the best mutifinction I’ve ever owned

on 2019-06-19 13:26:35

I’ve had a lot of printers and scanners since Apple’s original laser printer in the 80’s. Multifunction units have always been a pain, from HP, Canon, Epson and especially Brother (ugh). I usually found that they had good hardware and suffered from a ridiculous software interface on the printer and worse on the computer—bad for PC, worse for Mac. I really decided that Epson was irritating for making they’re units obsolescent so quickly and most (other than HP and Canon) for making the hardware cheaper and more disposable each new model.

Canon was my previous all around best experience but when that died out of warranty because someone put non-OEM ink in it and it detected that and bricked itself I had to look again. I had always disposed the ink cartridge concept but this was a last straw. This time I tried Epson (which I hadn’t tried for years because a decade ago I had really developed a dislike for them) because they now had the no cartridge option.

I couldn’t have been more surprised at how almost everything that I hoped would work on this machine actually did and well, with relative ease of use).
Touch screen: much better than expected.
ADF: only jams on stuff that is too crumpled not to expect a jam
User interface: better than most but not perfect by any means.
Scan to cloud: holy cow! Scan to cloud straight from the MFP without needing a computer! Unbelievable! Something I have wanted for years and yet no one else did it without the unit costing more that $1000.

Scannable and printable from iOS and Mac with in-app configurability (this article says no scanning from mobile... incorrect!).

This printer has produced great prints, great scans, few jams, feels less flimsy than some other brands (older Epsons, Brother...) prints pretty fast and scans pretty fast and most importantly, has been so reliable and solid that I haven’t had A chance to find out how Epson’s customer service or Tech-support is (so I rated tech-support at 50% because I don’t know).

*My only complaint: scanning from the glass automatically crops a lot from the sides of the page and enlarges the scan and I haven’t found the setting to override that bad “smart” function. I’m sure it’s configurable somewhere but I haven’t found it yet...

Overall best MFP I’ve yet used/ owned. Want to sell the aweful 5 year old large format Epson WF-7450 and replace with the new ET large format version.

Does not work with 5G or mesh networks

on 2018-07-13 16:22:19

As per the printer manual, it will only communicate on 2.5G WiFi networks. Remember those slow networks? As a result the printer is useless for those of us who are now using 5G or mesh network technology.
Regrettably Epson has chosen not to financially reimburse those of us who embrace up to date technology.
I predict the printer will be in landfill for sooner than one needs to replace ink.
