The Epson WorkForce Pro WF-7840 is a good all-in-one inkjet printer for small or home offices. It's well-built with easy access to paper jams and ink cartridges. It has three input trays: two in the front and one in the back. It has remarkable scanner features, including a flatbed with good resolution and color depth, an automatic document feeder that can perform duplex scanning, and faxing capabilities. It prints fairly quickly for black-only text documents, although the first page takes a bit more time. Unfortunately, the page yield for black ink is disappointingly low, but the cartridges are relatively affordable, which helps keep the cost-per-print low.
The Epson WorkForce Pro WF-7840 is great for family use. It has a fantastic scanner with a flatbed and a sheetfed that can perform automatic duplex scanning. It has a low cost-per-print for both color and black documents, and it has great color accuracy for casual photos. Sadly, photo quality is only okay, but it should be fine for occasional photo printing.

It prints black-only text documents fairly quickly, although the first page takes a while to print. It's affordable to print in both black and color ink; however, the black page yield is very low so you may need to replace the cartridge often.
The Epson WorkForce Pro WF-7840 is great for students. Although you may need to replace the ink often if you print regularly, the black ink cartridge is relatively affordable, which helps keep the cost-per-print low. It has a fantastic scanner and outstanding wireless connectivity options. Unfortunately, it doesn't have Bluetooth, and the first page takes a while to print.
The Epson WorkForce Pro WF-7840 is good for black and white printing. Although the printer yields a low amount of black text pages, its cost-per-print is still fairly low. However, you may need to replace the black cartridge often if you print large documents often. Luckily, high yield cartridges are available and should last longer, but we haven't tested them. Also, it's fast at printing black-only text pages.
The Epson WorkForce Pro WF-7840 is good for casual photos. Although there's some graininess and banding present in photos, they're decently detailed and colors look impressively accurate. It supports most photo sizes except for 2" x 3", and it's fairly affordable to print photos and in color.
The Epson WorkForce Pro WF-7840 has great build quality and design, made of a sturdy-feeling plastic. It has two paper trays at the front and a third at the back, with width sliders to accommodate for different paper sizes. It provides good access to paper jams and ink cartridges, but the printer needs to be on to replace the cartridges. The scanner lid stays open on its own, and its hinges can be lifted high enough to scan thicker items. The maintenance box that stores flushed ink is easily accessible from inside the printer, but it needs to be replaced once it's full.
Unfortunately, our unit makes many creaking and squeaking noises while printing. Also, the cartridge bay lid damper isn't very good as the final inch slams down.
It's very tall and wide due to its scanner and second input tray, so it needs some clearance above it to properly open the scanner lid.
The Epson WorkForce Pro WF-7840 has an amazing display screen. It features an LCD touchscreen that's easy to navigate and feels responsive. It has touch-sensitive buttons for Home and Help, and it has four shortcut buttons to interrupt or reset, and to view the paper settings or job status. It has great vertical visibility, but the viewing angle isn't as good from the side.
The Epson WorkForce Pro WF-7840's cartridge system is only okay. It doesn't yield many black ink pages, meaning you'll need to replace it quite often. However, it yields a higher number of color pages, so you shouldn't need to replace the color cartridges as often, although it depends on how frequently you print in color. If any of the color cartridges are empty, you can't continue printing in color; likewise, you can't print in color if the black cartridge is empty. High-capacity versions of the ink cartridges are available and should last longer, although we didn't test these. We couldn't find any third-party ink.
The Epson WorkForce Pro WF-7840 has exceptional scanner features. Its flatbed scanner has good resolution and color depth, and its automatic document feeder can perform double-sided scans. The scanner lid stays open on its own, and its hinges can be lifted high enough to scan thicker items. Also, it has copy and fax capabilities.
The cost-per-print is great. The costs remain relatively low over time, but it may quickly add up if you print in color often.
Although it takes some time for the first page to print, subsequent pages are faster for black-only text documents. On the other hand, color documents and photos take significantly longer. The two front paper trays can hold 250 pages each, and the rear tray can hold up to 50 pages.

These results are based on the actual physical photo, not the scanned image provided for reference above, which may not be representative of the printer's photo print quality.
It can print on most common paper formats, except for A5 and 2" x 3". The two front paper trays can hold 250 pages each, and the rear tray can hold up to 50 pages. Both front trays can be extended to fit tabloid-sized sheets.
It has fantastic connectivity options. While it doesn't have Bluetooth support, you can print wirelessly via Wi-Fi, AirPrint, or Mopria Print, and you can also print directly off a USB drive from the input at the front.
The Epson WorkForce Pro WF-7840 is compatible with the Epson iPrint app. You can print, scan, and copy from your mobile device, as well as monitor the ink levels, order cartridges, and perform maintenance tasks.
There's an Epson WorkForce Pro WF-7840 variant called the Epson WorkForce Pro WF-7820. Although we haven't tested it, the biggest difference seems to be the number of input trays: the WF-7840 has three input trays which hold a total of 550 papers, while the WF-7820 has only one which holds 250 papers. You can see the label of our unit here.
