What Ink Does the Epson WorkForce Pro WF-4740 Use?
Last Updated:Last updated: September 27, 2026. Reviewed by William Elward, founder of Castle Ink.
Correction: an earlier version of this article said the WF-4740 uses Epson 902 cartridges. It uses Epson 802/802XL.
Quick answer: what ink does the Epson WorkForce Pro WF-4740 use?
The Epson WorkForce Pro WF-4740 uses 4 Epson 802 DURABrite Ultra cartridges: black, cyan, magenta, and yellow. High-capacity 802XL cartridges fit the same slots. 802XL holds far more ink, so the cost per page drops sharply. For an office printing every day, XL is the clear choice. The pigment ink dries fast and resists smudging, which suits office documents.

Common questions about Epson WorkForce Pro WF-4740 ink
Should I buy Epson 802 or 802XL for the WF-4740?
802XL for most people. 802XL holds far more ink, so the cost per page drops sharply. For an office printing every day, XL is the clear choice. 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 802 and 802XL works.
What other printers use Epson 802 ink?
Epson 802/802XL also fits the WorkForce Pro WF-4720, WF-4730, WF-4734, EC-4020, EC-4030, and EC-4040. If you own more than one, a single stock of cartridges covers them all.
Will other Epson cartridges fit the WF-4740?
No. Epson 902 (WorkForce Pro WF-C5xxx series) and Epson 822 (WF-3820 and WF-48xx) are different cartridges and won't fit. Always match the number on your current cartridge.
Are compatible 802XL cartridges safe for the WF-4740?
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-4740?
Turn the printer on and lift the scanner unit. When the carriage stops, squeeze the tab on the empty cartridge and lift it out. Shake the new cartridge gently, remove only the yellow tape, and press it into its slot until it clicks. Close the scanner unit and let the printer charge the ink.

Why won't the WF-4740 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-4740 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-4740 print double-sided and fax?
Yes. The WF-4740 is a business all-in-one that prints, scans, copies, and faxes, with automatic 2-sided printing and an automatic document feeder. It shares 802 ink with the WF-4720 and WF-4730.
How much does the WF-4740 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.
