Solved: Help with cold reset for M1536dnf - HP Support Community

HPin718 · ‎02-16-2012

Hi-

First post, thanks for having me. This is an easy one:

Co-worker set up a system password for the front panel on the m1536dnf and never wrote it down. Genius. Anyway, nobody can access any front panel settings any longer.

Despite my user guide ninjitsu, I cannot seem to locate the cold reset procedure in the manual. If anyone knows what it is, that would be swell.

Thank you!

Bump. Hey guys -- this has to be an easy one. If nobody has this model, I'll take cold reset instructions for any comparable model LaserJet Pro.

The only online instructions I can seem to find involve holding down the "Go" button on older models -- no "Go" button on this guy. I see an "OK" button, and a variety of others....

Thank you in advance!

Hi. Thanks for the reply!

I just tested your reset procedure and unfortunately this doesn't work -- the machine is still password-protected.

To clarify, our network configuration has changed and we need to modify the printer's settings. However the user who configured the machine for security no longer remembers the password. It appears that we would need this to modify any of the system or network settings. The machine is basically dead in the water right now.

Does the reset procedure you outlined erase the security settings? How else can I do this? Again, our printer model is M1536dnf.

Thank you!

Hi HPin718,

The password you are talking about is to access the EWS - Embedded Web Server of the printer correct?

On page 183 of the manual there's this passage under "Product Security" (see below). They're calling it the "system password". It's not clear to me if this is the same password you'd use to get into the EWS because I didn't set up the printer initially. But it may be.

That's precisely the problem -- we can't enter the "System Setup" menu without the password. There must be some way of wiping this out with a cold reset type procedure.

Hi HPin718,

I will have to dig into this to see if there is a way to reset the printer so you can access the system setup menu. I will get back to you as soon as possible.
