HP Laserjet p2035n Can't set DHCP

[elmkd]

Hello I have a HP Laserjet p2035n connected via a switch to a LAN. The printer had a static IP address configured, and handled print jobs from connected PCs with no problem till yesterday.

The printer stopped responding to print jobs sent accross the LAN. Also, I was unable to access the web admin interface for the printer. I decided to reset it to factory settings and reconfigure it from scratch. I powered off the printer and held down both the GO button and the CANCEL button while powering the printer back on. The indicators all flashed in unison signalling that the printer had been reset.

When I printed a configuration page however, it indicated that the printer was still in manual IP configuration mode with an IP of 0.0.0.0 meaning that it would not pull a temporary IP from my DHCP server. Sure enough, I was unable to access the printer web admin interface after the factory reset.

I tried upgrading the firmware, I tried installing the HP software on my laptop to see if there was a setup programme that would reconfigure the printer ... I tried connecting directly via USB and successfully printed a few pages.

Can someone tell me if there is a way to  reset the network connection mode of the printer back to DHCP, perhaps using the buttons on the printer, or some tool that I can download.

Thank you for any help that you could offer.

Hi @elmkd 

I suspect your question would be better answered in the HP Enterprise Business Community, as your HP Printer is a commercial model.

My technical expertise is with consumer products and software, I am sure the commercial folks would be happy to help if you re-post your question for them to answer. The HP Enterprise Business Community is an HP Forum designed for the Commercial and Enterprise customers to help one another. I am sure you will find some HP folks there to help too.

Click here to view the Printing and Digital Imaging. When the page opens you will see the option to 'Log in' or 'Register Now' on the right. The commercial forums are separate from the consumer boards, thus you will need to register if you don't already have a commercial account.

You may find the HP LaserJet P2035n Printer support page helpful while you wait for somebody in the commercial Forum to respond to your inquiry.

Best of luck.

Hello:

Thank you for your response. I resolved the problem.

A static IP was reserved for the printer by my DHCP server.

The printer experienced a duplicate IP error on the LAN which was not indicated on the configuration page.

The printer was returned to factory default, but could not complete the initialization process (it is unclear why).

Network Information showed the following:

Status = Initializing

Host Name = ...

...

IPv4 Address = 0.0.0.0

IP Subnet Mask = 0.0.0.0

IP Default Gateway = 0.0.0.0

...

IP Configured By = Manual

etc...

This meant that the EWS could not be accessed, and the printer would not pull a new IP via DHCP.

Solution

-----------

1. Return printer to factory default by powering off, and holding down both CANCEL and GO buttons while powering on.

2. Ensure that there are no IP address conflicts on the network affecting the printer.

3. You may have to connect the printer to a separate subnet to get it to fully initialize and pull a temporary IP via DHCP

4.  Print a configuration page by holding down the GO button for 5 seconds and verify that you have a new IP

5.  Access the printer web admin page via the new IP and reconfigure the printer as needed. Static IP etc.

I hope that this helps someone else who might be confounded by this problem.

Thanks for returning to post the fix.

I used an old DSL residential router to provide a clean DHCP server with no conflicts. All my 0's populated with valid numbers on the restart of the printer!

I had the same values you did after I did a factory reset......

IPv4 Address = 0.0.0.0

IP Subnet Mask = 0.0.0.0

IP Default Gateway = 0.0.0.0

IP Configured By = Manual

My DSL router issed a valid private class C set of values.......

IPv4 Address = 192.168.1.98

IP Subnet Mask = 255.255.255.0

IP Default Gateway = 192.198.1.98

IP Configured By = DHCP

I connected back to my home network and restarted the printer and it returned....

YES ALL 0's and said manual again!!!!!!

I once again connected it to the standaolone DSL router and obtained valid addresses.

Without restarting the printer I connected it back to my network. The address  didnt conflict with anything else so I was able to ping it...... until I restarted the printer.

It once again failed to obtain an IP address!

My DHCP server is in a ATT U-Verse router. I see no way to flush just that device\MAC address.

I restarted my u-verse router and then restarted my printer.

It finaly obtained a DHCP assigned adress.

Apperantly the U-Verser router held the MAC address in the DHCP table?!?!

I will keep looking for a way I could have just cleared that device without causing downtime to the network. Not that it matters at my home but this was great practise for my Net+ recertification!

Thanks again for getting me over the first hurdle!
