The Cryptic Epson Language
Some manufacturers use simple error messages. Epson's built-in firmware often outputs raw hexadecimal memory codes. It also uses six-digit strings. These codes are very specific. They tell technicians exactly which part failed the boot check.
This master list decodes the most common error codes. It covers EcoTank, WorkForce, and Expression models.
The 0x Series: Hardware Faults
Hexadecimal codes starting with 0x usually mean a critical hardware failure. A component is completely dead, shorted, or disconnected.
- 0x97 / 0x9A: This is the most notorious WorkForce error. It means a massive power surge or short circuit happened. The F1/F2 SMD fuse on the motherboard is likely blown.
- 0x10: This is a scanner unit failure. The scanner motor cannot find its home position. The drive belt snapped or the glass is dirty.
- 0xEA / 0xE3: This is a carriage setup failure. The printhead carriage hit a physical block while trying to move left and right.
- 0x89: This is an ink out error. It happens when the sensor cannot read a third-party microchip on a cartridge.
- 0x69: This is a paper feed system failure. The rollers are turning. The optical sensor is not seeing paper moving past it.
The 6-Digit Series: Motor and Sensor Faults
Six-digit numerical codes are common on newer EcoTanks and WorkForce Pros. They usually represent motor overload errors. A motor is trying to spin against high resistance. The optical sensor tracking that motor might be dirty.
- 031006: This is a PF (Paper Feed) Motor failure. It is highly common on EcoTanks. Check for paper jams underneath the printer. Clean the round clear plastic disk on the left side.
- 031002: This is a CR (Carriage) Motor failure. The motor pulling the printhead left and right is struggling. Clean the long clear plastic strip running behind the printhead with alcohol.
- 000041: This is a home position fault. A tiny scrap of paper is blocking the far-right parking station. This prevents the printhead from locking into place.
- 100016: This is a Waste Ink Pad software lock. The counter has reached full capacity. You must use the WIC Reset Utility to clear it.
The 200 Series: Network and Firmware Crashes
Codes beginning with 20, 200, or 300 are generally software or network crashes.
- 2000020a: This is a Wi-Fi or Print Spooler crash. The printer received bad data over the network while booting up. Turn off your router and delete the print queue. Restart the printer to clear it.
- 30000000: This is fatal firmware corruption. The printer lost power during an update. You must boot into ROM Recovery Mode to flash fresh software via USB.
Epson Master Hex Error Code Reference Guide
Modern Epson printers use a standard hex error system. The controller logs a 6-digit hex code when a fault occurs. Below is the full diagnostic index.
Complete Hex Error Diagnostic Matrix
| Hex Code | Subsystem & Description | Recommended Technical Fix |
|---|---|---|
| 0x97 | Motherboard & Printhead Power Fault | Disconnect all cables. Wait 30 minutes. Clean head contacts. |
| 0x9A | Carriage Motor Overload | Clear debris from guide rail. Lubricate steel shaft. |
| 0x000041 | Paper Jam / Carriage Obstruction | Inspect paper path. Clean clear optical strip behind carriage. |
| 0x000031 | Scanner Motor Home Position Failure | Unlock flatbed scanner lock. Clean white optical strip. |
| 0x000021 | Paper Feed Roller Motor Stall | Clean clear round disc on the left side. |
| 0x031002 | Carriage Encoder Read Error | Wipe encoder strip with water. Check sensor for dust. |
| 0x031006 | Paper Feed Gear Desync (L3110 / L3210) | Re-align the white pickup roller gear cluster. |
| E-01 | Fatal Hardware Stop / Object Interruption | Check for dropped staples or paperclips. Perform 10-minute power reset. |
Frequently Asked Questions
How do I clear error codes that persist after removing a paper jam?
Epson firmware stores mechanical errors in memory. Disconnect the power cord from the wall for at least 15 minutes.
What is the difference between an "E" error and a "0x" error?
"E" errors are simple consumer alerts shown on LCD screens. "0x" hex codes are low-level engineering logs accessed via the PC driver.
