Epson WorkForce Pro WF-7840 Printer Review

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.

The Epson WorkForce Pro WF-7840 has impressive color accuracy. Although the accuracy may not be good enough for professionals who need exact color reproduction, it should be more than enough for casual color printing or photos.

The Epson WorkForce Pro WF-7840 has decent photo printing quality. Photos look a little grainy and there's some banding present in gray areas, but otherwise, it produces good detail.

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.
