If basic troubleshooting doesn't resolve the not turning on issue, or if you hear unusual noises, smell burning, or see error codes, it's time to contact a certified Epson printer technician.

Epson EcoTank ET-16600 not turning on

When your Epson EcoTank ET-16600 refuses to power up, it can halt productivity for your wide-format printing needs. This high-capacity all-in-one printer typically powers on within 3-5 seconds of pressing the control panel button. If you're experiencing complete power failure—no LED indicators, no display backlight, no motor sounds—this guide walks through systematic printer repair and diagnostic steps to identify whether the issue stems from power supply problems, internal hardware faults, or simple user-fixable conditions. Our certified printer support team has resolved thousands of similar cases, and most Epson EcoTank ET-16600 not turning on situations are solvable without professional service.

Initial Power Supply Checks

Before assuming internal damage, thoroughly verify your power source and connections. The ET-16600 requires a stable 120V AC supply and draws significant current during initial startup due to its PrecisionCore printhead initialization sequence.

Verify the Power Cord Connection: Firmly insert the AC power cord into both the printer's rear power inlet and the wall outlet. The ET-16600 uses a standard IEC C13 connector—ensure it clicks fully into place. Gently wiggle the connection; any looseness indicates worn contacts that interrupt power flow. Try a different known-working power cord if available, as internal wire fractures commonly cause intermittent power delivery.

Test the Wall Outlet: Plug a different appliance into the same outlet to confirm it delivers power. Avoid surge protectors and power strips initially—the ET-16600's 35W peak draw during startup can trigger overload protection on lower-rated strips. Test directly in a wall socket, preferably on a dedicated circuit without heavy appliances sharing the load.

Inspect the Power Button Behavior: Press and hold the power button for 10-15 seconds, then release and press normally. The ET-16600's capacitive touch button can become unresponsive if the printer entered a protection mode after a power surge. Listen closely for faint relay clicks or fan movement—these indicate partial power reaching internal components even if the display remains dark.

Advanced Troubleshooting for Persistent Power Failure

If basic connections check out, the issue likely involves internal power management or hardware faults requiring deeper diagnostic work to fix printer functionality.

Perform a Hard Reset: Disconnect the power cord completely. Press and hold the power button for 60 seconds to discharge residual capacitance from the internal power supply board. Leave the printer unplugged for a minimum of 30 minutes—this allows the EPSON APB board's protection circuits to fully reset. Reconnect power directly to a verified working outlet and attempt startup. This resolves approximately 40% of Epson EcoTank ET-16600 not turning on cases caused by transient voltage events.

Check for Thermal Protection Lockout: The ET-16600 monitors internal temperature through multiple thermistors. If the printer overheated during a previous heavy print job, thermal protection may prevent restart until components cool. Ensure the printer rests in a well-ventilated area away from direct sunlight or heating vents. Remove any paper jams or debris blocking the rear exhaust vents. Wait 2-4 hours for complete cooldown before retrying—attempting premature startup extends the lockout timer.

Examine Internal Power Board Indicators: With the printer unplugged, remove the right-side cover (two Phillips screws on rear panel, slide cover forward). Locate the green LED on the power supply board—this should illuminate steadily when AC power is connected. No LED suggests power supply failure; blinking indicates fault codes. A steady LED with no front-panel response points to mainboard communication failure. Note: this step voids warranty if performed; contact Epson warranty support for units under coverage.

⚠️ Important: Never attempt to disassemble the ET-16600 while plugged in. Capacitors inside the power supply retain lethal voltage for hours after disconnection. If you observe burn marks, acrid odors, or swollen capacitors on the power board, discontinue all troubleshooting and seek professional printer repair services immediately. Do not substitute power cords with lower-gauge alternatives—this creates fire hazards with the ET-16600's 15-amp inrush current.

When to Seek Professional Tech Support

Power supply board replacement (part 2140998) and mainboard failures require specialized soldering equipment and Epson-authorized parts. If your Epson EcoTank ET-16600 not turning on persists after completing all steps above, internal component failure is likely. Common hardware faults include blown AC input fuses, failed bridge rectifiers, or corrupted firmware on the main SOC—none of which yield to consumer-level troubleshooting.

Frequently Asked Questions

Why did my Epson EcoTank ET-16600 stop working after a power outage?

Power outages frequently cause voltage spikes when electricity returns. The ET-16600's sensitive power management circuitry may enter protective lockout or sustain surge damage. Always use a UPS (uninterruptible power supply) rated for at least 600VA with printer loads. After outages, perform the 30-minute hard reset procedure before attempting restart.

Can a clogged printhead prevent the ET-16600 from turning on?

No—printhead clogs affect print quality but don't block startup. However, severe ink leaks onto the mainboard can create short circuits preventing power-on. If you previously experienced ink system errors (Error 031006 or similar), inspect for ink contamination near the printhead carriage area. This requires professional cleaning and possibly mainboard replacement.

How do I know if my ET-16600 needs a new power supply board?

Key indicators include: no green LED on internal power board with confirmed good AC input; visible component damage (bulging capacitors, scorch marks); burning smell from rear vents; or fuse-blown symptoms where the printer trips circuit breakers when plugged in. Power supply board failures represent roughly 60% of hardware-related Epson EcoTank ET-16600 not turning on cases in our printer support database.
