E-05
Epson Printer
Severity: MinorWhat Does This Error Mean?
Epson error E-05 means the printer cannot detect or recognize one of the ink cartridges. The printer stopped because it found a cartridge that is not installed correctly, is empty, or is not recognized. This is usually fixed in minutes by removing and reinserting the cartridges.
Affected Models
- Epson EcoTank ET-2800
- Epson Expression Home XP-4100
- Epson WorkForce WF-2850
- Epson Expression Home XP-2105
- Epson XP-4150
Common Causes
- An ink cartridge is not seated fully and has a poor connection with the printer contacts
- One or more ink cartridges are completely empty and need replacement
- A third-party or refilled cartridge is not being recognized as compatible
- The ink cartridge's electrical contacts are dirty or smudged
- The protective tape on a new cartridge was not fully removed before installation
How to Fix It
-
Open the printer's front cover or cartridge access panel. Wait for the carriage to move to the center before reaching inside.
Never reach into the printer while the carriage is still in motion.
-
Remove all ink cartridges one at a time. Set them on a clean, dry surface.
Note which cartridge goes in which slot — they are often color-coded and must go back in the correct positions.
-
Check each cartridge for the orange protective tape. If any tape is still attached to the bottom or sides of the cartridge, remove it completely.
Leaving the tape on a new cartridge is one of the most common mistakes and prevents the printer from detecting the ink.
-
Gently wipe the copper contacts on the bottom of each cartridge with a dry, lint-free cloth.
Clean, smudge-free contacts ensure the printer can read the cartridge chip accurately.
-
Reinsert each cartridge firmly into its correct slot. Press until you feel and hear a click, then close the cover.
If a cartridge does not click in, it is not fully seated. A loose cartridge will give a recognition error.

Frequently Asked Questions
My cartridge is brand new but E-05 still shows. What do I do?
First, make sure you removed all orange protective tape from the cartridge before installing it. Then confirm the cartridge is pressed firmly into the slot until it clicks. If the error persists, try cleaning the contacts on both the cartridge and inside the slot with a dry lint-free cloth.
Can I use third-party ink cartridges in my Epson printer?
Third-party cartridges often work in Epson printers, but results vary by brand and model. Epson printers can reject cartridges whose chips do not match the expected specifications. If you are getting E-05 with a third-party cartridge, testing with a genuine Epson cartridge will confirm if compatibility is the issue.
How do I know which cartridge is causing the E-05 error?
Open the Epson printer software on your computer or the Epson Smart Panel app on your phone. Navigate to the ink level display — it will show which cartridge or cartridges are flagged with an error. Alternatively, check the printer's display screen if it has one — it often indicates which color has a problem.
