If your Epson WorkForce Pro WF-3720 printing blank pages, you're not alone. This frustrating issue affects many users and typically stems from clogged printheads, depleted or improperly installed ink cartridges, or incorrect printer settings. The WF-3720 uses PrecisionCore technology with four individual DURABrite Ultra ink cartridges (Black 702, Cyan 702, Magenta 702, Yellow 702), which requires proper maintenance for consistent output. This guide walks you through proven troubleshooting steps to restore normal printing without unnecessary printer repair costs.
Quick Diagnostic Checks
Before diving into advanced troubleshooting, run these basic checks to narrow down the cause of your Epson WorkForce Pro WF-3720 printing blank pages. These simple steps often reveal the problem immediately.
1
Verify Ink Levels and Cartridge Installation: Open the scanner unit and check that all four cartridges (Black 702, Cyan 702, Magenta 702, Yellow 702) are properly seated with the locking levers clicked down. From the printer's LCD panel, navigate to Settings > Maintenance > Ink Levels to confirm no cartridges show empty or low. Remove and reinsert any cartridge that feels loose, ensuring you hear the click of the locking mechanism. Even partially lifted cartridges cause complete print failures on this model.
2
Run the Built-In Nozzle Check: From the printer's control panel, go to Settings > Maintenance > Nozzle Check and print a test pattern. If the page emerges completely blank, this confirms the printhead isn't firing ink. Compare any partial patterns against the on-screen reference to identify which color channels are affected. Save this printout—it helps determine whether you need targeted cleaning or full printhead recovery.
⚠️ Important: Avoid running more than three consecutive printhead cleaning cycles without printing a nozzle check between each. Excessive cleaning wastes significant ink and can overheat the PrecisionCore printhead in the WF-3720, potentially causing permanent damage. Always allow 6-12 hours between deep cleaning attempts for optimal results.
Printhead Cleaning and Recovery
3
Perform Standard Printhead Cleaning: Access Settings > Maintenance > Head Cleaning on the LCD touchscreen. The WF-3720 will pump cleaning solution through the printhead channels to dissolve dried ink. This process takes approximately 2 minutes. After completion, print another nozzle check to assess improvement. For mild clogs, one cleaning cycle often restores output. If gaps remain, proceed to Power Cleaning—but only if standard cleaning fails, as Power Cleaning consumes substantially more ink.
4
Execute Power Cleaning (If Needed): For persistent Epson WorkForce Pro WF-3720 printing blank pages issues, use Settings > Maintenance > Power Cleaning. This intensive process takes about 10 minutes and requires at least half-full ink cartridges to initiate. The printer will prompt you to confirm adequate ink levels before starting. Power Cleaning flushes the entire ink delivery system and often clears severe clogs that resist standard cleaning. Print a nozzle check immediately afterward to verify success.
5
Manually Clean the Printhead Contacts: Power off and unplug the printer. Lift the scanner unit, then carefully remove all four ink cartridges. Locate the copper-colored contact chip on each cartridge and the corresponding pins inside the carriage. Gently wipe these with a lint-free cloth slightly dampened with distilled water—never tap water. Dry thoroughly with a fresh cloth before reinstalling. Corroded or dirty contacts frequently cause the WF-3720 to register cartridges as present while blocking electrical signals that trigger ink ejection.
Software and Settings Troubleshooting
6
Check Driver Settings and Paper Type: On your computer, open Devices and Printers, right-click the WF-3720, and select Printing Preferences. Under the Main tab, verify "Black" or "Color" is selected—not "Draft" mode with zero ink density. Confirm the Paper Type matches your loaded media; mismatched settings can trigger protective blank-page output. Also check the Maintenance tab in Epson's printer software for any "Skip Blank Page" or ink-saving modes that might misinterpret your document. Update to the latest driver from Epson's support site if settings appear corrupted.

Why does my Epson WF-3720 print blank pages even with full ink cartridges?
Full cartridges don't guarantee ink flow. The most common cause is a clogged PrecisionCore printhead, which can occur after periods of inactivity. Electrical contact issues between cartridges and the print carriage, or corrupted printer firmware, can also cause this symptom despite adequate ink levels.
Can I use third-party ink cartridges without getting blank pages?
While some users successfully use compatible cartridges, the WF-3720's firmware updates have increasingly restricted non-genuine ink recognition. Third-party cartridges may register as empty, trigger error messages, or cause intermittent blank-page output due to chip incompatibility. For reliable troubleshooting, test with genuine Epson 702 cartridges first.
How often should I print to prevent future blank page issues?
Print at least one color page weekly to keep ink flowing through the PrecisionCore nozzles. The pigment-based DURABrite Ultra ink in the WF-3720 resists drying better than dye inks, but extended dormancy still causes clogs. Enable the printer's "Auto Nozzle Check and Cleaning" feature in the maintenance menu for additional protection.
