Epson WorkForce 840 All-in-One Printer review: Epson WorkForce 840 All-in-One Printer

The Epson WorkForce 840 printer ships with four separate ink cartridges for cyan, magenta, yellow, and black. To factor the most cost-efficient price per page, we base our cost per page on Epson's extrahigh-capacity ink cartridges. The extrahigh-capacity black cartridge costs $28.49 for a vendor-estimated 945 pages, which works out to just over 3 cents per page. For color, the extrahigh-capacity three-pack for cyan, magenta, and yellow costs $54.10 for 7.2 cents per page. Both costs fall just below the mean for an all-in-one printer of this size.

Performance
The Epson WorkForce 840 turned in a strong performance in our tests on the whole. It pumped out 12.48 pages per minute (ppm) on our all-black text speed test, which was nearly the same score as the Epson WorkForce 520 and the HP Officejet Pro 8500A Plus. The WorkForce 840 performed just as quickly when printing graphics, especially in our presentation speed test, in which it outpaced the competition by printing 10 color PowerPoint slides at a clip of 6.79 ppm. Unfortunately, it struggled in our photo speed test, taking roughly 70 seconds to print a 4x6-inch photo on glossy photo paper for a time of 0.86 ppm. Competing models were two to three times faster at printing photos.

The WorkForce 840 proved a bit speedier than average on our scan and copy tests. It scanned a 10-page color document at 5.59 ppm, and copied a 10-page monochrome text document at 5.48 ppm.

We reviewed its output quality in side-by-side comparison with the HP Officejet Pro 8500A Plus and found that the WorkForce 840 produced slightly crisper text and brighter, more vivid color. It almost looked like the Officejet Pro 8500A Plus used too much ink in printing text, particularly with smaller fonts, resulting in slightly blurred edges. The WorkForce 840 produced razor-sharp edges and finer-looking text than the Officejet Pro 8500A Plus.

Lastly, we appreciate the WorkForce 840's low operating noise levels. Any small office can feel claustrophobic when you're trying to get work done next to a loud, overbearing printer, and the WorkForce 840 barely made its presence known during spooling, scanning, and printing.

Service and support
Epson backs the Epson WorkForce 840 with a limited one-year warranty that includes toll-free customer support weekdays from 6 a.m. to 6 p.m. PT. Further support is available online with a model-specific troubleshooting guide, FAQs, e-mail support, driver updates, and document downloads. You can also purchase exchange/repair coverage at $39.95 for one year or $59.95 for two years.

Conclusions
It's not the fastest photo printer, but for all other jobs the Epson WorkForce 840 excels. We recommend this multifunction inkjet for its high-quality prints, rapid text and graphics speeds, easy-to-navigate control panel, and abundance of features that include autoduplexing, an ADF, wired and wireless networking, and support for mobile printing.
