Seaory Printer Won't Turn On or Keeps Restarting (S25, S26, S28, R330, R660)
Seaory support · Power
Updated October 8, 2026
A Seaory printer that will not turn on, or that boots to Ready and then restarts again, is far more often a power adapter problem than a printer problem. In our support records, most of these cases ended with a new adapter, and the printer was fine. Here is how to tell in two minutes, before you ship anything anywhere.
Quick answer
Plug the adapter straight into a wall outlet and look at the light on the adapter. Light off: the adapter or the outlet. Light dims or blinks when the printer restarts: the adapter is failing, and we will replace it. Light steady but the printer is dead: contact us with a short video. Only ever use the adapter that came with the printer.
Check it in this order
1
Plug straight into the wall
Take the power strip, surge protector or UPS out of the loop and plug the adapter directly into a wall outlet you know works. Push both ends of the cable in firmly: the plug into the adapter and the small connector into the back of the printer.
2
Look at the light on the power adapter
The adapter brick has its own small light.
- Off on an outlet that works: the adapter has failed. Contact us for a replacement.
- On and steady: the adapter is getting power. Go to step 3.
3
If the printer keeps restarting, watch the adapter light while it does
This is the classic R660 and R330 pattern: the screen shows Initializing, reaches Ready, goes dark and starts again. If the adapter light dims or blinks at the moment the printer restarts, the adapter cannot hold the load when the printer warms up. A new adapter fixes it. Take a short phone video showing the adapter light and the printer screen together, and send it to us.
4
Make sure it is the original adapter
Adapters from laptops, other printers or a spare drawer often fit the same plug but do not supply the voltage the printer needs. The printer may power on and look normal, then jam, fail mid-print or restart. Check the label on the adapter against the label on the printer. If you are not sure, send us a photo of the adapter label.
5
Adapter fine, printer still dead? Stop there
If the adapter light is steady and the printer shows nothing at all, do not open the printer. Send us a video of you pressing the power button with the adapter light in the shot, plus the serial number, and we will take it from there.
What you see, and what it means
| What you see | Most likely cause | Next step |
|---|---|---|
| Nothing at all, adapter light off | Failed adapter or dead outlet | Try another wall outlet, then contact us |
| Restarts over and over, adapter light dims or blinks | Adapter failing under load | Contact us for a replacement adapter |
| Powers on but jams or fails mid-print, using a different adapter | Wrong adapter, not enough voltage | Switch back to the original adapter |
| Nothing at all, adapter light steady | Printer side | Send a video and the serial number |
| Error 31 on the screen while using a different adapter | Not enough power for the printhead mechanism | Switch back to the original adapter |
| White screen with a red light | Display or internal connection | Contact us. Do not open the printer |
A humming or buzzing adapter
Some adapters hum or whine quietly while working. If the printer runs normally, Seaory's guidance is that this can be ignored. If the noise bothers you, contact us and we will look at replacing it.
Still stuck?
Send these with your first message and we can skip a round
Most support cases take an extra day only because we have to ask for these. Attach them up front and we can usually give you the next step the same day.
- Printer model and serial number (label on the back of the printer)
- A photo of the label on the power adapter
- A short phone video showing the adapter light and the printer screen together while it fails or restarts
- Whether the adapter has been replaced before, and when
