Epson Printer Error Code E-20 — What It Means & How to Fix It

What Does This Error Mean?

Epson error E-20 means the scanner unit is open or not fully closed. The printer has detected that the scanner lid is not latched down properly. This is a minor error — closing the scanner unit correctly will clear it immediately.

Common Causes

The scanner lid was left open or not pressed down fully after a copy or scan
An object such as a book or thick document is preventing the scanner lid from closing flat
The scanner lid hinge is damaged or misaligned and the lid cannot close properly
The scanner unit was opened to access ink cartridges and not fully latched when closed
A sensor inside the scanner hinge is dirty or faulty and falsely reporting the lid as open

How to Fix It

Look at the top of the printer. Check if the scanner lid — the flat panel you lift to place documents — is fully closed.

Even if the lid looks closed, it may not be fully latched. Give it a gentle press along the entire front edge to make sure.
If you were copying a thick book or large document, remove it and let the scanner lid close flat.

Thick items like hardcover books can hold the lid slightly open. The scanner lid must rest flat to clear the error.
Open the scanner lid fully and inspect the hinge area and glass surface for any debris, paper, or objects blocking closure.

Even a small rubber eraser or pen can prevent the lid from seating fully.
Close the scanner lid again firmly. You should hear or feel a soft click as it latches.

Do not slam it — a firm but gentle press along the front edge is all that is needed.
If the error clears, print a test page to confirm the printer is working normally. If the error persists with the lid clearly shut, restart the printer.

Turn the printer off, wait 30 seconds, and turn it back on. This resets the sensor reading.

When to Call a Professional

Error E-20 is almost always fixed by simply closing the scanner lid. If the lid is physically damaged and cannot close fully, the hinge or housing may need repair. Epson-authorized service centers can inspect and fix scanner lid hardware for around $40 to $80.

Frequently Asked Questions

Why does my Epson printer show E-20 even when the scanner lid is closed?

The lid sensor may not be registering the closed position correctly. This can happen if the sensor contacts are dirty or if the lid is slightly warped. Try pressing firmly along the entire front edge of the lid, then restart the printer.

Can I still print while error E-20 is showing?

No. Epson printers with an active error code will refuse all print, scan, and copy jobs. You need to clear the error first before the printer will accept any new tasks.

How do I access the ink cartridges on an Epson printer with a scanner unit?

On most Epson all-in-one printers, you lift the entire scanner unit upward — not just the lid. There is usually a support rod or prop arm that holds it open while you access the cartridges. Always make sure to close it fully and press it down until it clicks before powering up.
