Epson WorkForce Pro WF-7840 Printer Review From A To Z In 2023

The Epson WorkForce Pro WF-7840 is an inkjet printer that can do everything. It is made for a small office or a home office. This big model has two trays that can hold a total of 500 pages and a feeder in the back. It is a wide-format printer, which means it can print pages up to 13″ x 19″ in size. It has a flatbed scanner and an automatic document feeder that can both scan sheets up to tabloid size, even if they are on both sides. Like many office printers, it can automatically print on both sides of the page, and it can connect to a wide range of wireless devices.

1. Design

The Epson WorkForce Pro WF-7840 is made of plastic that feels strong and has a great design. It has two paper trays in front and a paper feeder in the back. It can handle different sizes of paper thanks to width sliders. It’s easy to get to paper jams and ink cartridges, but to change the cartridges, the printer needs to be on. The scanner lid stays open on its own, and the hinges can be lifted high enough to scan thicker items. The maintenance box that holds flushed ink is easy to get to from inside the printer, but once it’s full, it needs to be replaced.

When printing, our unit makes a lot of creaking and squeaking sounds. Also, the damper on the cartridge bay lid isn’t very good because the last inch falls with a thud.

Note that there is a similar printer called the Epson WorkForce Pro WF-7820 that should work about the same, but it only has one 250-page paper tray.

Since the Epson WorkForce Pro WF-7840 is an inkjet printer, there is a chance that the ink will dry out and the printheads will get clogged. It needs to be taken care of with ink, and it has built-in tasks for cleaning the printhead, checking the printhead nozzles, aligning the printhead, and cleaning the paper guide. To change the cartridges, you need to turn on the printer, choose “Ink Cartridge Replacement” in the settings, and then wait for the cartridge carrier to move into view. Even though it doesn’t take long to do, the extra step makes this model a little slower than others. This is especially annoying because you have to do it so often because it doesn’t give you many pages. On the plus side, you don’t have to refill its paper tray as often because it has two large trays that can hold up to 250 pages each and a manual feeder that can hold up to 50 pages. If there’s a paper jam, you can easily get to the sheet rollers by taking off a back panel. You can also take out both the input tray and the output tray to get to the front sheet rollers.

The cartridge system on the Epson WF-7840 is just okay. It doesn’t print a lot of black pages, so you’ll have to replace it a lot. But it prints more color pages, so you might not have to replace the color cartridges as often. This depends on how often you print in color, though. There are also versions of the cartridges that last longer and have a high yield. If any of the color cartridges are empty, you can’t print in color. If the black cartridge is empty, you also can’t print in color. Check out the Brother MFC-J6945DW if you want a wide-format printer that can print more pages.

2. Document

Even though it’s not the fastest printer we’ve tested, the Epson WorkForce Pro WF-7840 is pretty fast at printing black-and-white documents. But it takes a lot longer for color documents. Also, after being idle for more than an hour, it takes a while to print a single page. On the plus side, it can print automatically on both sides of letter- or tabloid-sized paper.

3. Photo

The Epson WorkForce Pro WF-7840 prints photos that aren’t too bad. The photos look a little grainy, and there is some banding in gray areas, but other than that, the detail is good. Check out the Epson WorkForce Pro WF-7310 if you want a wide-format printer that also makes better-looking photos.

The scanned images up top are just for your reference. Because they were scanned and uploaded, they look worse than the real photos. The actual photos are what the score is based on.

The Epson WorkForce Pro WF-7840 is about right when it comes to colors. Even though the accuracy isn’t good enough for professionals who need exact color reproduction, it’s more than enough for casual color printing or photos. The blues are usually the most off, but your pictures of the ocean and sky will still look good.


4. Mobile apps and connectivity

It has a lot of great ways to connect. Even though it doesn’t have Bluetooth, you can print wirelessly with Wi-Fi, AirPrint, or Mopria Print, and you can also print directly from a USB drive using the front port.The Epson iPrint app works with the Epson WorkForce Pro WF-7840. You can print, scan, and copy from your mobile device. You can also check the ink levels, order cartridges, and do maintenance tasks.

All View

The Epson WF-7840 works well in small offices or at home. It seems well-made and has a great scanner that can scan both sides of a page and send faxes. Text documents that are only black print pretty quickly, but the first page takes a while. It’s cheap to print in both black and color, but the page yield for black ink is low, so you may need to replace the cartridge often.
