If your Epson Printer is displaying error code 0xB3, the machine has detected an ink pad overflow condition — the internal waste ink absorber pads have reached or exceeded their maximum capacity and must be reset or replaced before printing can continue. Error 0xB3 on Epson printers is a maintenance error rather than a mechanical failure, but it does prevent all printing until addressed. Here is how to diagnose and fix Epson Printer error 0xB3.
Follow the steps below one at a time — many error codes can be fixed faster than they look.
Error 0xB3 is Epson’s waste ink pad overflow error. Epson inkjet printers route waste ink — produced during printhead cleaning cycles and printhead priming — into a set of absorbent foam pads located inside the printer’s base. Epson programs a counter into the printer’s firmware that tracks the estimated amount of waste ink deposited into these pads over the printer’s lifetime.
When this counter reaches 100%, the printer stops all printing functions and displays the 0xB3 error (or a similar code depending on the model — some Epson printers show “A printer’s ink pad is at the end of its service life” instead of the hex code). This is a deliberate safety measure to prevent ink from overflowing the pads and damaging the printer’s internal electronics.
Step 1: Locate and download the Epson Adjustment Program. The Adjustment Program (sometimes called the Service Utility) is the official tool for resetting Epson waste ink counters. It is model-specific — you need the version for your exact printer. Search for your model number followed by “Adjustment Program” and download from a reputable source, or obtain it through an authorised Epson service provider.
Step 2: Run the waste ink counter reset. Connect your printer to the computer via USB. Open the Adjustment Program and select your printer model. Navigate to the waste ink pad counter reset function. Read the current counter value — it will show 100% or close to it. Select the reset option and apply it. The program writes a new counter value to the printer’s EEPROM.
Step 3: Power cycle the printer after reset. Once the counter reset is complete, turn the printer off and unplug for 30 seconds. Power back on. The 0xB3 error should no longer appear and the printer should initialise normally.
Step 4: Replace the physical waste ink pads. Resetting the counter extends the printer’s operational life but does not physically empty the pads. If the pads are saturated, they should be replaced. Access the pads by removing the printer’s base or bottom panel (model-dependent). Pull out the old pads, dispose of them, and insert new pads of the same size. Replacement pads cost £5–£15 for most models.
Step 5: Consider Epson EcoTank models for replacement. If the repair cost plus pad replacement exceeds the printer’s value, newer Epson EcoTank models (ET series) are designed with larger waste ink tanks that last significantly longer before requiring service.
Can I keep using the printer after the 0xB3 error appears? No — the printer disables all printing functions when this error is active. The counter must be reset before printing can resume.
Is it safe to reset the waste ink counter without replacing the pads? It is possible but carries a risk — if the pads are physically saturated, continued use without replacing them can cause ink to overflow and damage the printer’s internal components or surface beneath the printer.
Is error 0xB3 covered by warranty? Waste ink pad overflow is considered normal maintenance and is typically not covered by the standard warranty after the first occurrence. Epson does offer a paid pad reset service through their service centres.
