HP P2015 reset back to DHCP?!

[googlemad]

Either another technician is going round setting HP P2015 printers back to DHCP or they're doing something weird, but I've just had a call to say the printer wasn't working in a classroom (It has been working on a static IP for months), turns out it has defaulted back to the DHCP setting?!

Any ideas why it did this?

Have you passworded the web interface? If not, it's possible someone entered the IP into explorer. I have found with HP 2600n's that it's still possible to default everything in a few button clicks (on the printer itself). Bit stupid on HP's part if you ask me.

Some printers do if turned off for a period of time.

Set a dhcp reservation for it so it always gets the same ip.

If you power cycle a P2015 and hold down the "Go" button for 10 seconds it will reset to factory settings.
Maybe one of the kids has found this out?

I've had HP and Brother printers "lose" network settings before, at first I assumed it was a kid resetting it, but it has happened in a staff office. I think they just do it sometimes because they'ret bored and saying .. "right stuff this, what's out there...".

I set everything via DHCP now, it' just easier, and means I can tell how many IPs I have assigned to printers.

Yes, we've had the P2015's lose their network settings, apparently the later firmware 'helps' with this issue.

I didn't know of the trick to reset them to factory settings, how useful....

My 2600n printers all randomly reset themselves back to DHCP from static with no fiddling at all... Seems to be a power thing, some weekends they do, some they don't!

This has been happening to ours just recently...but it's only a recent thing. Its been fine for years with a static IP but all of a sudden- it keeps defaulting to DHCP.

Any ideas WHY?

Its the factory reset by pressing the GO button down. I got round the problem by setting up static DHCP leases for my P2015s and referencing them in the print driver port by host name.

Static DHCP is the way forward really.

How do you do this? Do you mean you put the assigned IP address in the port or a name?

[Geoff]

Actually going back over the server setup my inital description of what I was doing isn't quite right. It appears I setup a cname to point to the dhcp registration done by default by the printer (seems to relate to the printers serial number). Then set the TCP/IP port in the printer driver to this hostname.

I just use the ip address in the print driver port

[marsdenprimary]

Ah I see- i'm doing this but the printer itself keeps resetting to default dhcp...do i need to actually assign it the ip address our the server?

[Geoff]

as I said, it doesn't look like I went down that route in the end. I just pointed a human readable cname at the unique default hostname the printer came up with.
