Correction: an earlier version of this article listed yields for standard 822 cartridges that we couldn't confirm. The table now shows Epson's published 822XL yields.
Quick answer: what ink does the Epson WorkForce Pro WF-4820 use?
The Epson WorkForce Pro WF-4820 uses 4 Epson 822 DURABrite Ultra cartridges: black, cyan, magenta, and yellow. High-capacity 822XL cartridges fit the same slots. 822XL is rated for about 1,100 pages per cartridge, several times the standard size, so it's the better value for regular office printing. The pigment ink dries fast and resists smudging, which suits office documents.

Common questions about Epson WorkForce Pro WF-4820 ink
Should I buy Epson 822 or 822XL for the WF-4820?
822XL for most people. 822XL is rated for about 1,100 pages per cartridge, several times the standard size, so it's the better value for regular office printing. See Is XL ink actually worth it? Standard vs. XL with real numbers.
Can I mix standard and XL cartridges?
Yes. Each cartridge is read separately, so any mix of 822 and 822XL works.
What other printers use Epson 822 ink?
Epson 822/822XL also fits the WorkForce Pro WF-3820, WF-3823, WF-4830, WF-4833, and WF-4834. If you own more than one, a single stock of cartridges covers them all.
Will other Epson cartridges fit the WF-4820?
No. Epson 802 (WF-4720/4730/4740) and Epson 902 (WF-C5xxx) look similar but aren't interchangeable. Always match the number on your current cartridge.
Are compatible 822XL cartridges safe for the WF-4820?
Yes. Quality compatible and remanufactured cartridges print like OEM, and using them doesn't void your warranty under U.S. law. Epson firmware updates have been known to reject some third-party chips, so consider turning off automatic firmware updates.

How do I replace the ink in the WF-4820?
With the printer on, start the replacement from the control panel (or when the printer prompts you) and open the ink cartridge cover it shows. Remove the empty cartridge, shake the new one gently, unpack it, and push it into the matching slot until it locks. Close the cover and let the printer charge the ink.

Why won't the WF-4820 recognize a cartridge?
Reseat it firmly until it clicks, make sure the yellow tape is fully removed, and wipe the chip with a dry lint-free cloth. Turn the printer off for a minute. If a compatible cartridge stops working right after a firmware update, contact the seller for a replacement. More fixes: Printer says ink cartridge not recognized: how to fix it.
Why are prints from my WF-4820 faded, streaky, or blurry?
Run a nozzle check from the Maintenance menu first. Gaps mean a clog: run a head cleaning (up to two or three cycles). If the check is complete but lines look jagged or doubled, align the print head instead; see our print head alignment guide. More fixes: Why is my printer printing streaks?.
Why did the first set of cartridges run out so fast?
New Epson printers use part of the first set to charge the ink system. It's a one-time cost. See why the first cartridges run out fast.
Does the WF-4820 print double-sided and fax?
Yes. The WF-4820 is a business all-in-one that prints, scans, copies, and faxes, with automatic 2-sided printing and an automatic document feeder. The WF-4830 and WF-4834 use the same 822 ink.
How much does the WF-4820 cost to run?
With XL cartridges, the ink cost per page is far lower than with standard cartridges. Compare the numbers for your usage with the Printer ink cost calculator.
