Epson Printer Error 0xa6 — Ink System Fault

What Does This Error Mean?

Error 0xa6 signals a fault in Epson's internal ink delivery system — usually the ink pump, capping station, or ink tubes. This is a fatal error that stops all printing. A power cycle occasionally clears it if the fault was a temporary pressure imbalance, but hardware failure typically requires a service center.

Affected Models

Epson EcoTank ET-2800
Epson EcoTank ET-4850
Epson EcoTank ET-3850
Epson WorkForce WF-2960
Epson Expression Photo XP-8700

Common Causes

The ink pump motor has failed or is seized after extended use
The capping station (which seals the print head when idle) is stuck or has a damaged seal
An ink tube is kinked, cracked, or has a dried ink blockage preventing flow
Air has entered the ink delivery system and created a pressure fault
The ink pump ran dry because the ink tank was completely empty for an extended period

How to Fix It

Turn the printer off and unplug it. Wait 2 full minutes before turning it back on.

A temporary pressure imbalance in the ink system sometimes resolves after a full rest.
On EcoTank models, check that all ink tanks have sufficient ink. Top up any empty tanks.

Running the pump with empty tanks causes mechanical stress and can trigger 0xa6.
Look at the capping station — the small rubber assembly in the bottom-right of the printer interior where the print head parks. Ensure it is not visibly damaged or misaligned.

A capping station that cannot seal properly causes the pump to run continuously, eventually triggering a fault.
Power the printer back on. If the error clears, run a head cleaning cycle to prime the ink system.

This confirms the ink system is delivering ink normally after the pressure reset.
If 0xa6 returns immediately or after a short time, the printer needs professional service.

Continuing to print with a faulty ink pump risks permanent damage to the print head.

When to Call a Professional

Ink system faults on 0xa6 are rarely user-fixable because the pump and ink tubes are deep inside the printer. An Epson service center can flush the ink system, replace the pump, or replace the capping station. This repair costs $70 to $130 and is most worthwhile on EcoTank models given their higher original value.

Frequently Asked Questions

Can a clogged print head cause 0xa6?

A severely clogged head forces the ink pump to work harder, which can eventually cause a pump fault. However, 0xa6 is more often a pump or capping station issue independent of clog severity. Run nozzle checks and cleaning cycles before the error appears to prevent pump overload.

Is 0xa6 more common on EcoTank printers?

EcoTank printers use a continuous ink supply system with more tubing and a more active pump than cartridge printers. This makes them slightly more susceptible to ink system faults like 0xa6 over their lifetime. Regular use (printing at least weekly) keeps the ink moving and reduces the risk.

Can I prevent 0xa6 by printing regularly?

Yes — ink that sits static in tubes can dry and create blockages. Printing at least one full-colour page per week keeps ink flowing and the pump exercised. Avoid leaving an EcoTank printer idle for weeks at a time.
