Initialization loop after network change

[MtWash]

We have several HP Laserjet M1212nf MFP printers that are all network connected. Currently they reside on a 190 subnet, which makes them directly accessible to the computers that are adding them to print.

We are making some network changes and placing all of our printers onto their own separate vlan (170) which they are then added to a print server, and computers on the 190 network access the printers through the print server instead.

All of our other printers seem to have no issue with the change, but the M1212nf printers end up in an initialization loop that won't go away until added back to the 190 network. These printers are grabbing their IP's via DHCP where we set up resevations for them. The issue is still the same if we manually assign the IP through the printer interface. Even then, they will randomly go into a loop for no reason and then come back on the 190 network.

Some of these printers will also go into a loop for a couple loops before coming back online without having been switched over, just by simply attempting to print a configuration report from the printer directly. 

Unless firmware is updated automatically, we have not done a firmware upgrade, which most of the information I have located online points to. 

What would be the cause of this, and a solution to resolve?

[EDIT] As an additional note, I have one of these printers that was stuck in an initialization loop no matter what network it was on, and I just powered it on without being connected to the network, and the initialization loop is gone. 

I restored it's defaults just in case, and plugged back into the network, and it immediatley goes back into the loop.

Hey there! @MtWash, Thanks for stopping by the HP Support Forums!

I understand your printer is stuck at initialization error on your printer.

Don't worry I'll try to help you out.

Did you make any changes to your printer?

Please try performing a hard reset on your printer and check if it helps.

In some cases, removing the ink cartridges and resetting the printer can clear the error message.

1.Turn on the printer.

2.Wait until the printer is idle and silent before you continue.

3.Disconnect the USB cable from the rear of the printer. If your printer has a network or wireless connection, leave it connected.

4.Remove the ink cartridges from the printer. 

5. With the printer turned on, disconnect the power cord from the rear of the printer and from the wall outlet or power strip.

6.Wait at least 60 seconds.

7.Plug the power cord back into the wall outlet.

   note:

HP recommends connecting the printer power cord directly to a wall outlet.

8.Reconnect the power cord to the rear of the printer.

9.Turn on the printer, if it does not automatically turn on.

The printer might go through a warm-up period. The printer lights might flash, and the carriage might move. 

10.Wait until the warm-up period finishes and your printer is idle and silent before you proceed.

11.Reinsert the ink cartridges, and then close the ink cartridge access door.

12.If you receive a prompt to print a calibration page, do so. 

13.If you disconnected the USB cable, reconnect it to the rear of the printer.

14.Try to print.
 

If the issue still persists try performing a super NVRAM reset on your printer and check if it helps.

Since the steps to perform NVRAM reset is confidential, I will send you the steps in a private message. Please watch your inbox for more information.

I sent you a PM, but just to note here (for anyone who may come across this in the future). Did both suggestions. The init loop appears to be gone after the second suggestion, but the printer, while apparently visible to the print server (all of our printers are networked), it will not print the test page, which just sits in the print queue. 

The printer icon is solid and active in the printers and devices, and if powered off, the icon does fade. So the print server is certainly seeing the printer, and the correct driver is installed. I did notice that while it used to use the IP address for the port, it now uses the WSD port. Even adding the IP address port in does not correct the issue.

Hi @MrRobot,

The info you provided in email was what helped correct the init loop issue. 

I managed to get the system to connect via USB, and ran the firmware updater to bring the firmware to current. This stopped the init loop. 

For anyone reading this in the future with the same issue:

@MtWash, Thanks for your quick response and time.

I appreciate your efforts for trying out the steps.

As you mentioned after restarting the printer you got the init message again on your printer.

Try updating the printer firmware and check if it helps.

Link to update the printer firmware.

If the issue still persists after trying out the steps.

It is a hardware issue with the printer, Please contact HP support for service options.

Have a great day ahead!

Take Care!
