HP Neverstop Laser 1000n toner issue

[BraRik83]

Brand new HP Neverstop 1000n. After initial toner, its time to fill up.
Used original toner 103A and refilled (with 2 reloads) but indicator show its still low level and send notification to PC everytime I sent document to print. What is the problem, why printer didn't register 2 reloads? It's blinking low level toner, all the time.

@BraRik83, Welcome to HP Support Community!

I see that the ink levels are incorrectly shown on the printer, follow the steps below-

1. Turn the printer on, if it is not already on.
2. Wait until the printer is idle and silent before you continue.
3. With the printer turned on, disconnect the power cord from the rear of the printer.
4. Unplug the power cord from the wall outlet.
5. Wait at least 60 seconds.
6. Plug the power cord back into the wall outlet.
7. Reconnect the power cord to the rear of the printer.
8. Turn on the printer, if it does not automatically turn on.
9. Wait until the printer is idle and silent before you proceed.

Update the printer firmware

Download available firmware updates from the HP website

With the printer on and connected to the computer, go to HP Customer Support - Software and Driver Downloads, and then identify your printer. Look for and install any available firmware updates. Refer to the document HP Printers - Updating or Upgrading Printer Firmware

Now, check the ink levels.

Hope this helps! Keep me posted.

I tried with all suggested things but nothing helped. Unplug and plug in power cable as you suggested, didnt work. 
Flashed with new firmware but didnt work, too. 

Is there anything else I can try?

This looks like a hardware issue.

Please reach out to the HP Support in your region regarding the service options for your printer.

Hope this helps!

Just to conclude this problem - after the printer was sent to HP service, it determinated that was a hardware problem and the one pin on the imaging drum was broken. After refilling, printer didn't recognize the toner and refilling was just physically without software registering this. Printer is still operational but toner status is always set to low. Solution is to replace imaging drum.

Thanks for all suggested help.

Cheers
