Epson Printer Error Code 0xEB — What It Means & How to Fix It

What Does This Error Mean?

Epson error code 0xEB means the printer has detected a problem with an ink cartridge — either an incompatible cartridge, a cartridge that is not seated properly, or an ink system communication failure. This error can also appear after replacing cartridges if the new ones are not recognized. The printer will refuse to print until the cartridge issue is resolved. In most cases, reseating the cartridges or replacing with genuine Epson cartridges clears the error.

Common Causes

Ink cartridge is not fully seated in its slot
A third-party or refilled cartridge is not being recognized by the printer
Cartridge chip contacts are dirty or corroded
The cartridge was installed with the printer powered off
A genuine Epson cartridge has a defective chip that the printer cannot read

How to Fix It

Open the printer's cartridge cover. Remove each ink cartridge one at a time and re-press it firmly into its slot. You should hear a click when it is properly seated.

Even cartridges that appear installed can sometimes be slightly out of alignment. Firm reseating is the first and most successful fix.
Check for any orange or yellow protective tape on the new cartridges that was not removed. This tape covers the contacts and nozzles and must be fully removed before installation.

Some Epson cartridges have a pull-tab tape that removes a protective strip from both the nozzle area and the contact area.
If using third-party cartridges, try replacing them with genuine Epson cartridges. The 0xEB error is commonly caused by incompatible chips on aftermarket cartridges.

Epson printers use DRM chip technology that can block cartridges not recognized as genuine. Firmware updates can also make previously working third-party chips incompatible.
Clean the chip contacts on the cartridge and the corresponding contacts in the carriage with a dry, lint-free cloth. Do not use water — just a dry cloth to remove dust and ink residue.

If contacts have significant ink buildup, a cotton swab barely moistened with distilled water can help — let everything dry fully before reinstalling.
Turn the printer completely off, wait 10 seconds, and power it back on with cartridges correctly installed. Some recognition errors require a full power cycle to clear.

Never install or remove cartridges with the printer powered off — the carriage must be in the access position, which only happens when powered on.

When to Call a Professional

Error 0xEB is almost always user-resolvable. If genuine Epson cartridges continue to show 0xEB after reseating and contact cleaning, the printer's cartridge contact assembly may be dirty or damaged. An Epson service technician can inspect and clean the carriage contacts. For printers under warranty, contact Epson support first.

Frequently Asked Questions

Can I bypass error 0xEB to keep printing?

On some Epson models with LCD screens, there is an option to acknowledge the cartridge warning and continue printing. However, if the cartridge is not being recognized at all, the printer cannot monitor ink levels and may stop mid-print. Switching to genuine Epson cartridges is the most reliable solution.

Why did 0xEB start after a firmware update?

Epson periodically releases firmware updates that tighten cartridge authentication. An update can cause previously working third-party cartridges to suddenly show 0xEB. This is intentional — Epson firmware is designed to maintain compatibility only with genuine Epson cartridges.

My genuine Epson cartridge shows 0xEB — is it defective?

It could be. First reseat it firmly and clean the contacts. If 0xEB persists with a new genuine cartridge, the cartridge itself may have a defective chip. Contact Epson support or the retailer where you purchased the cartridge for a replacement.
