Epson Wfc5790 Admin Password Updated May 2026

This guide covers the default credentials, why they exist, how to reset a forgotten password, and critical security notes for network administrators.

Method 1: Using the Printer's Control Panel

1. Navigate to the Setup Menu: On the printer's control panel, go to the Setup or Settings menu. The exact label might vary depending on the firmware version.

2. Select Maintenance or Admin Settings: Look for an option labeled Maintenance, Admin Settings, or something similar.

3. Find the Reset Option: Within the admin settings, search for an option to Restore Default Settings or Reset. You might need to enter the current password, but if you've forgotten it, proceed to the next method.

Interface and Daily Use

Navigating the password interface is done primarily through the 4.3-inch color touchscreen.

• Touchscreen Responsiveness: Entering a complex alphanumeric password on the small touchscreen keyboard can be tedious. The interface is responsive, but lacking a full QWERTY keyboard layout (it often defaults to alphabetical lists), hunting for special characters takes time.
• Web Config Utility: This is where the admin password shines. Once the printer is on the network, managing settings via a browser (Web Config) is much easier. However, the browser interface has a very short session timeout. If you step away to grab a coffee while configuring SMTP settings for scanning, you will likely return to a locked screen requiring you to re-enter the admin credentials. This is secure, but slightly annoying for the IT admin performing the initial setup.

Method 1: The "Hotel" or "Network" Reset (Non-Destructive)

This method resets only the network and admin password settings while preserving your address book, print counters, and job logs.

How to do it on the WF-C5790:

1. Turn off the printer using the power button.
2. Press and hold the Stop button (the red circle with the exclamation mark) and the Power button simultaneously.
3. When the LCD screen lights up, release only the Power button.
4. Continue holding the Stop button for about 10-15 seconds until you see "Reset Network Settings" or a maintenance mode menu.
5. Use the arrow keys to select "Reset Admin Password" or "Network Reset."
6. Confirm the action.
7. The printer will restart. After rebooting, try the default passwords (blank or 11111).

Caution: This does not work on all firmware versions. Epson has patched some older bypass methods.

Method 2: The Printer Control Panel

1. Tap the Home icon on the touchscreen.
2. Select Settings (The gear icon).
3. Scroll to General Settings > System Administration.
4. You will be prompted for a password here. Try the default or serial number.

Review: Managing the Admin Password on the Epson WF-C5790

A Necessary Hurdle for a Secure Office Workhorse epson wfc5790 admin password

When setting up the Epson WorkForce Pro WF-C5790 for a business environment, one of the first and most critical touchpoints is the administrator password setup. Unlike consumer printers that often default to "admin/admin" or have no security at all, the WF-C5790 takes a firm stance on security right out of the box.

This review covers the user experience of setting, managing, and recovering the admin password on this specific model.

Method 3: Using Epson’s Software (Web Config or EpsonNet)

If you are currently connected to the printer via your local network (and just forgot the password, but not the IP address), try accessing the printer’s web interface.

Web Config Access:

1. Find the printer’s IP address (print a network status sheet by holding the Stop button for 5 seconds).
2. Type the IP into a web browser.
3. Go to Product Security > Administrator Settings.
4. If you see a "Reset Password" link, click it. Some firmware versions allow this from a trusted IP address without the old password.

EpsonNet Config Utility:

• Download EpsonNet Config from Epson’s support site.
• Run the utility, find your WF-C5790, and look for a "Reset to Defaults" option. This often overrides the password lock locally.
