Epson WorkForce Pro WF-4830  Printer Review

The Epson WorkForce WF-4830's build quality is excellent. It has a sturdy-feeling plastic body, with two paper trays to accommodate different paper sizes and easy access to paper jams and ink cartridges. The scanner lid stays fully open on its own, meaning you don't have to hold it, and its hinges extend to accommodate thicker items on the scanning bed, like textbooks and magazines.

The display is excellent. It's responsive, and the interface is user-friendly. Visibility is good from above and below, but it's much harder to see from the sides. You can tilt the panel upwards to make it easier to see when standing above the printer, though the tilt range is limited.

The cartridge system is okay. The black cartridge runs out quickly; however, the color cartridge's yield is good. Although having three color cartridges means you can change the empty ones without needing to replace them all at once, the printer doesn't let you print in color if one is empty. You also can't print in color if it's out of black ink. There are high-capacity Epson T822XL cartridges available if you want to increase the yield, which might be cheaper in the long run and more environmentally friendly. If you want a printer that yields more prints, check out the HP Smart Tank 5101.

Like most inkjet printers, the Epson WorkForce Pro WF-4833 requires some maintenance as the printheads can clog if you don't use it for a long time. There are a few maintenance functions built-in to help resolve this issue, like head cleaning, nozzle check, and head alignment. You'll have to replace the ink cartridges fairly often as they have low page yields, though you can get XL cartridges that'll last longer. The printer needs to be on to change the cartridges, but the process is easy, and the printer will let you know if you installed them properly. You can access the sheet rollers via a panel on the back to remove paper jams. The two input trays hold a total of 500 sheets of paper, so you won't have to refill them all that often. You can see the user's manual here. There's a removable maintenance box that stores ink flushed during the printhead cleaning at the right rear corner of the printer, which you need to replace when it's full.

This is an inkjet printer, which means it can clog if left unused for an extended period. Inkjet printers use liquid ink that flows through extremely fine printhead nozzles. During extended periods of inactivity, this ink can evaporate, thicken, or dry out, potentially blocking the ink flow. Environmental factors such as dry air, dust, temperature fluctuations, or direct sunlight can accelerate clog formation. Clogs may cause missing lines, faded colors, or complete print failures. To reduce the risk, we recommend printing periodically and storing the printer in a cool, stable environment. If clogs occur, most inkjet printers include built-in maintenance routines to help clear the printheads, which are detailed in the Expected Maintenance test box of this review.

If you don't want to deal with unclogging, laser printers use a different system with dry toner and a drum instead of ink and printheads, which avoids this issue.

This printer features non-replaceable printheads paired with a low ink volume, which can become quite costly to upkeep if you frequently need to manage clogs. The flushing volume on hand can help clear many issues, but it may not be enough for more stubborn blockages, which may then require multiple cartridges. You also can't simply replace the printheads as a fallback option if severe clogs develop. Careful operation and consistent printing become essential to avoid problems.

The cost-per-print is great. Although you have to replace the ink cartridges relatively often, they aren't overly expensive, so your maintenance cost will remain relatively low over time.

The Epson WorkForce WF-4834 prints black documents quickly, but it's slow to print color documents. Its photo printing speed is decent and about the same as most inkjet printers. There are two input trays; each tray holds 250 sheets of paper. The Epson WF-4820 variant only has one 250-sheet input tray.

Black and white documents look great. Text looks very sharp; however, there's a lot of grain in the colored areas, and the halftones (dots) are very visible in some places. The printer uses some blue ink to print black-and-white documents if you select the 'Black-and-White' option in the print settings. You can see in this image that there's a light blue tint.

The Epson WF-4833 prints color documents well. Text and fine elements look clear; however, the colors are a little washed out, and there's some coloring in the grays.

The Epson WF-4833 has a feature-rich scanner. Its automatic document feeder can perform duplex scanning, making the task of scanning long, two-sided documents hassle-free. To scan double-sided sheets, the printer does two passes. The flatbed scanner lid stays fully open on its own, so you don't need to hold it, and its lid hinges extend to accommodate thicker items, like a textbook or thick document. The Epson WF-4820 variant also has an ADF but doesn't support duplex scanning, and its feeder can only hold 35 sheets. If you need a larger flatbed scanner, check out the Epson WorkForce Pro WF-7840.

The built-in OCR (Optical Character Recognition) feature lets you scan and save documents as searchable PDFs, but it makes frequent mistakes.

The scan quality is great. Scanned documents look clear with very little noise; however, colors look lighter than the originals, and fine details are sometimes faint or completely absent.

The Epson WorkForce WF-4833 has an okay color gamut. Except for greens, it reproduces bright, saturated colors fairly well. However, it struggles with dark blues and greens, as well as light blues and pinks. Unfortunately, color transitions look very grainy.

The color accuracy is okay. It's good enough for a splash of color on a report or to print out family photos, but it isn't ideal for professional work that requires near-perfect accuracy. Blues and yellows are the most inaccurate, and skin tones look overly warm.

This printer reproduces small details remarkably well. Fine elements and distant objects are easily identifiable. The only complaint is that the halftones (dots) are very prominent and soften the edges of objects.

The Epson WF-4833 can print directly off a USB flash drive. The USB port is on the front left side of the printer.

The Epson iPrint app lets you print, scan, and copy from your smartphone. You can also perform maintenance tasks like checking ink levels, head cleaning, and alignment, and you can purchase ink directly from the app. This printer is also compatible with Epson's Smart Panel app, which provides access to functions like ID Scan and Preset Scan. However, it can't convert text files, Word documents, and webpages, which the Epson iPrint app can do on the Android version. On iPhones and iPads, you can print these files from whichever app you use to view them.

You don't need to install drivers on Chrome OS and macOS devices to use the printer, but you do on Windows devices. You can download the drivers here.
