I have roland spds when i switch it on display show verify test

Dear
You have not mentioned the model. However you can download the SAMSUNG EASY PRINTER MANAGER which can show which door is opened. The door has a leaver which close the switch inside the printer to acknowledge the door is closed, either the lever broken or mis-aligned. You can check it with a insulated plastic knife pushing the sensor switch.
hope the above may get you some idea.
thanks.

It's likely a coin battery, like the type in a computer, used to keep the bios or settings ram user settings (whatever)memory

software problem

did you fix it?

I am having the same issue with a SPD-11 that ahd brought from Japan. Please let me know if you get a resolution for your issue.

The card I have always been using is now also suddenly giving this message. I found an old SanDisk 16MB and a 1GB SanDisk that works perfectly in my Boss 864 and they also give the same message. Trying to go into formatting brings the message "no card!"
