Epson ET-2850 Error Code 034004: Loud Noise and Paper Jam Troubleshooting Guide

Question:
Our Epson ET-2850 printer at our non-profit stopped printing after accidentally pulling in too many sheets of paper and becoming jammed. After removing the jammed paper, the printer now makes a very loud, gear-like grinding noise when attempting to print and during initialization upon powering on. Additionally, it displays an error message: "Non-printing features are available 034004." We’re willing to replace parts if needed. Could you help identify the issue and suggest possible solutions?

Answer:

Understanding Epson Error Code 034004

The error code "034004" translates to an "Insoluble paper jam error," which can be caused by:

• Foreign objects lodged inside the printer

• Deformation of the printer's main frame

• A failure or malfunction in the change lever mechanism

• Residual or hidden paper jams

This error matches precisely your description of the loud grinding or catching noises coming from your Epson ET-2850, typically indicating mechanical interference or damage within the paper feed mechanism or the duplexer (double-sided printing unit).

Steps to Troubleshoot and Resolve the Issue:

Step 1: Inspect for Foreign Objects

• Turn off and unplug your printer completely.

• Carefully inspect the paper feed path, rollers, and duplexer area using a flashlight.

• Look specifically for small objects (pens, staples, jewelry, etc.) or residual scraps of paper that may have become lodged inside.

• Remove any discovered objects gently and carefully to avoid causing further mechanical damage.

Step 2: Examine for Mechanical Damage

• Check the paper feeder, hopper mechanism, and duplexer area for any visible signs of deformation, misalignment, or damage.

• Listen and look closely for gear damage or stripped teeth in the gears, as these are common after paper jams.

• Inspect rollers and ensure they rotate smoothly and are not damaged or stuck.

Step 3: Test and Replace Damaged Components

• If visual or physical inspection reveals broken or worn-out gears or rollers, replacing these components may restore proper functionality.

• Specific Epson ET-2850 replacement parts can often be sourced online or through official Epson parts dealers.

Step 4: Reset and Test Printer Operation

• After resolving any physical obstructions or damage, power your printer back on and perform an initialization and test print.

• Listen carefully during startup and test printing to ensure the noise and jamming issues have ceased.
