Hi @herbert77060,
Welcome to The HP Support Community.
Thank you for posting your query, I will be glad to help you.
I understand the toner LED on your HP LaserJet Pro P1606dn continues to blink after replacing the toner cartridge, here are a few additional troubleshooting steps you can try:
Check for Toner Cartridge Installation:
- Make sure the toner cartridge is installed correctly and seated properly. Sometimes, the cartridge may not click into place fully, which can cause the blinking LED.
Inspect for Obstructions:
- Even after cleaning with canned air, check inside the printer for any small paper pieces, dust, or toner residue that might still be obstructing the printer or sensors.
Reset the Printer:
- Power off the printer, wait 30 seconds, and then power it back on while holding down the "Go" button (the green button) on the printer until the printer goes through a series of lights and resets.
Check the Printer’s Sensor:
- If there's an issue with the toner sensor, the printer might continue blinking the LED even with a new cartridge. Unfortunately, this would require some technical expertise to diagnose, and it might need a service technician.
Perform a Printer Self-Test:
- Run a self-test or print a configuration page to check the printer's overall condition. This will help you confirm if the issue is related to the toner or something else in the printer.
If none of these steps help, there could be an issue with the toner sensor, or the printer might need professional service.
I hope this helps.
Take care and have a good day.
