How Do I Reset My Epson Wf 3720 Printer Full Official

Turn the printer back on. The error message should be gone. Print a test page to confirm.

Important: Resetting the counter without replacing the physical ink pads will eventually lead to ink leakage. The correct long-term fix is to replace the waste ink pads or install an external waste ink tank.

| Error Code | Meaning | Reset Required | |------------|---------|----------------| | 0x9A | Waste ink pad counter full | Adjustment Program reset | | 0x69 | Communication error | Power cycle + USB reconnection | | 0x42 | Fatal internal error | Service menu NVRAM reset | | 0x1F | Ink cartridge not recognized | Factory reset + reinstall cartridges | | Service Required | Generic hardware lock | Waste ink pad reset |

If you cannot find the adjustment software, you can try resetting via the Epson cloud, though this rarely works for a full waste-pad reset.

Warning: This will not fix the "Service Required" error. It only resets your network and menu preferences.

Before we begin, it is important to know why your printer is asking for a reset. The Epson WF-3720 tracks two main things:

| Method | Truly "Full Reset"? | Difficulty | Removes Errors? | |--------|---------------------|------------|------------------| | Menu Settings Reset | ❌ No | Easy | No | | Unplug 30 sec / Power cycle | ❌ No | Easy | No | | Service Mode EEPROM Reset | ✅ Yes | Hard (requires precise timing) | Yes (temporarily) |

Bottom line: If you need a full reset to clear a permanent error (e.g., "Service Required" or ink pad counter full), the standard user manual is useless. You must enter Service Mode (Power + Stop) and reset the EEPROM. However, this is a temporary fix—once the physical ink pads are saturated, no reset will prevent leaking. Consider replacing the pads or using an external waste ink tank before resetting.

My advice: Only perform this if you’re technically comfortable and accept that a "full reset" doesn’t fix hardware—it just tricks the printer into thinking it’s new.

To perform a "full" reset of your Epson WorkForce Pro WF-3720, you can use the built-in control panel to restore factory settings or use specialized software for a "waste ink counter" reset if the printer is showing a maintenance error. 1. Factory Reset (Control Panel)

Reconnect: Plug the power cord back in and turn the printer on. 3. Waste Ink Counter Reset (Maintenance Error)

If your printer is locked with a "Service Required" error (red light), a standard factory reset will not work. This error means the waste ink pads are full.

You will typically need third-party software like InkChip or an adjustment program to reset the internal counter to zero. Important Notes:

Re-Configuration: A full reset removes your Wi-Fi password and scan-to-email settings. You will need to set these up again from scratch.

Admin Password: If the printer asks for an administrator password during the reset, the default is usually the product's serial number, found on a label on the back or side of the unit.
