Quick answer: what ink does the Epson WorkForce Pro WF-4720 use?

The Epson WorkForce Pro WF-4720 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-4720 ink

Should I buy Epson 802 or 802XL for the WF-4720?

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 WF-4730, WF-4734, WF-4740, 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-4720?

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.

How do I replace the ink in the WF-4720?

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. Step-by-step: How to install an ink cartridge in an Epson printer.

Why won't the WF-4720 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 non-Epson cartridge stopped working right after an Epson firmware update, reseating won't help: Epson designs those updates so the printer accepts only genuine Epson cartridges. More fixes: Printer says ink cartridge not recognized: how to fix it.

Why are prints from my WF-4720 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-4720 print double-sided and fax?

Yes. The WF-4720 is a business all-in-one that prints, scans, copies, and faxes, with automatic 2-sided printing and an automatic document feeder. The WF-4730 and WF-4740 use the same 802 ink.

How much does the WF-4720 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.

What WorkForce Pro WF-4720 owners ask

These are the questions that come up most for this printer on retailer Q&A pages, Epson's support pages and owner reviews, answered in our words.

My cartridges stopped being recognized after a firmware update. What happened?

Epson builds its firmware updates so the WF-4720 works only with genuine Epson cartridges, and Epson's own FAQ tells owners to replace non-Epson ones. That includes remanufactured cartridges like ours, so if you use them, set Epson Software Updater to "Never" and keep automatic firmware updates off.

Epson discontinued my printer. Will my spare 802 cartridges fit the replacement?

No. Epson lists the WorkForce Pro WF-4830 as the replacement, and it takes Epson 822 cartridges. Use up your 802 stock in the WF-4720 or another 802 printer first.

Does the document feeder scan both sides automatically?

No. The WF-4720's 35-sheet feeder scans one side at a time. Epson kept automatic two-sided scanning from the feeder for the WF-4740, which has a 50-sheet feeder.

Can I connect it to a wired network?

Yes. It has 10/100 Ethernet as well as Wi-Fi, Wi-Fi Direct, USB and NFC.

How much printing is it built for?

Epson rates the WF-4720 for up to 25,000 pages a month, but recommends up to 1,500 pages a month for regular use. Above that, a bigger office printer makes more sense.

WorkForce Pro WF-4720 quirks worth knowing

  • Besides the four cartridges, it uses an Ink Maintenance Box (Epson T6715), which is replaced separately from the ink.
  • It has a single 250-sheet front tray (plus 20 photo sheets or 10 envelopes). The WF-4730 and WF-4740 add a second tray for 500 sheets.
  • It can print on paper up to 8.5 x 47.2 inches, which is handy for banners and long forms.
  • NFC lets an Android phone tap the printer to print without joining a network.
