my canon pixma tr8620a printer won't turn on at all, no lights, nothing. is it dead?

Diagnosis

A completely unresponsive Canon PIXMA TR8620a with no indicator lights points to a power delivery failure. The primary suspects are a faulty power connection or a corrupted internal state. In rare cases, it indicates a critical internal hardware failure.

How to Fix It

First, perform a full power cycle to reset the printer's internal power controller:

1. Unplug the power cord from the rear of the printer and from the wall outlet.
2. Wait at least 60 seconds to ensure any residual power drains from the printer's capacitors.
3. While unplugged, press and hold the physical power button on the printer for 10 seconds.
4. Firmly reconnect the power cord directly to a known-working wall outlet (avoid power strips or surge protectors for this test).
5. Plug the other end securely into the printer's power port.
6. Press the power button once to turn it on.

If That Didn't Work

Systematically isolate the problem:

• Test the Outlet & Cord: Verify the wall outlet is live by plugging in a lamp or phone charger. If possible, test the printer with a different, undamaged AC power cord.
• Inspect for Physical Damage: Check the printer's power port for any bent pins or debris. Examine the power cord for cuts, kinks, or a damaged plug.
• Bypass Surge Protectors: Plug the printer directly into a wall outlet to rule out a failed power strip or uninterruptible power supply (UPS).

Heads Up

This model draws minimal power in standby (0.8W), so a persistent no-power state is a serious symptom. Do not attempt to open the printer or service internal components yourself, as this involves high-voltage parts and voids the warranty. The final resolution for an internal failure is to contact Canon Support for repair or service options.
