HP Laserjet Pro p1606n - Attention, Ready, and Go lights on

[JoseKreif]

The Attention, Ready, and Go lights are on after the printer powers on. I've powered it off and on numerous times and yes, I do have it plugged directly into the wall.

I can access the printer through the web interface using it's assigned IP address, but that's all. Nothing can be printed until the printer comes out of this error state.

I beleve you are referring to the "Select" button as the Go light in this scenario.  There are only two lights on the 1600, a Attention light (Triangle !) and a Ready light (Circle arrow). 

Here is what the Service Manual has to say about the light codes:

Attention light

Generally, the Attention light blinks when the printer is out of paper, when a jam has occurred, or

when other problems that need attention occur.

The Attention light is on and one of the Supplies Status gauges is blinking the first time a non-HP

supply is installed.

Ready light

The Ready light is on when the printer is ready to print (experiencing no errors that prevent printing)

and blinks when it is receiving data to be printed.

Ready light and Select button

● When the Ready light is on and the Attention light is blinking, pressing (Select) continues the

print job after you load print media for a manual feed, or clears some errors.

● When the Ready light is blinking, the front door has been opened and then closed. Press

(Select) to return the printer to the Ready

> I can access the printer through the web interface using it's assigned IP address, but that's all. 

This suggests the printer can fully boot and network connect.  The problem is likely something physical on the printer or perhaps a bad print job stuck in a queue somewhere.  Try disconnecting the printer from everything and rebooting.  See if it comes back with the same light codes or not.  If so then there is likely a part that needs servicing.

Take a screenshot of the control panel for us and we can help you verifiy if we are missing anything else.

Sorry, but you are mistaken. There are 4 lights on this printer. Please review more carefully

I was looking at the Service Manual for the 1600, not the P1600.  Your screenshot helped clarify which model to look for  so thanks for the attachement.

According to the P1600 Service Manual on page 129:

Attention , ready , and go lights cycle. Toner light is off.

NOTE: The power button backlight is on.

The formatter is initializing. No action required. Wait for the initialization period to end. The product enters the Ready

state when the initialization period is finished.

And here on page 131:

The attention , ready , and go lights are on. Toner light is off.

NOTE: The power button backlight is on.

The product has experienced a fatal error from which it cannot recover.

1. Turn off the product.

2. Wait 30 seconds, and then turn on the product.

3. Wait for the product to initialize.

4. If the error persists, contact

customer support for more

information.

Sounds like your printer is hosed.  Perhaps a firmware error or soemthing else with the formatter that is not allowing it to complete the initialization process.  Do you recall taking any firmware updates or experience any storms that could have sent a surge to the printer? In either case you are likely looking at replacing the formatter which is likely going to cost more than a replacement printer after parts and labor.

You can try to clear any temporary problems with the memory by performing a Cold/NVRAM reset:

To restore the product to the factory-default settings, follow these steps.

1. Turn the product off.

2. Turn the product on, and while it is initializing press and hold both control-panel buttons at the same

time until all lights blink in unison.

If you are interested in attempting to repair the damage another technique to consider would be removing components one at a time and testing the boot process.  See if the printer can clear that part of the startup check to help you isolate what could be malfunctioning.  If you cannot have any impact on the boot process then its likely the formatter.
