HP Color Laserjet issue

Question

Since this site is a Q&A for system administrators and desktop support professionals I'd decided to post my question here. Not sure if this is the best stackexchange website for this.

We have an HP Color Laserjet 4700n of course out of warranty. And we have an 49.4CF2 Service error. According to several sources online, this is firmware related.

When I switch of the printer and switch it back on, it gives this error again. I have tried to give it a cold reset. But that didn't work either. I have downloaded both firmware downloads from hp.com first one has an application which transfers the firmware to the printer, but after about 5% the printer switches again to 49.4CF2 Service error. I also tried the second firmware. So I used filezilla to transfer the .rfu file. The start of the transfer looked good. But again, after about 5% there was a lost connection.

I do not know what else I can try to resolve this error.

p.s. ping-ing the printer works. but stops when the error occurs. same for webinterface of the network printer.

EDIT: as Jan Marek and Ezio Zanghellini said: the firmware is still not updated. Seems impossible!

Solution 1

Seems that it is solved!

Since I am no expert in the kitchen with ovens etc. I had decided to skip Pauska's solution (sorry, nothing personal)

I disconnected the network cable. The printer boots fine then. But I can only print by network. So I reconnected it and changed the static IP address from .190 to .192 (on the end) and reconfigured a lot of pc's to use the new (lan) ip.

And the service error is gone. I still have no idea what might have caused this. Maybe a PC in the LAN keeps sending wrong stuff to the 192.168.1.190 IP address?

Solution 2

I've heard about people baking the formatter (yes, in a oven) to fix bad soldering on the HP P2015.. It's a crazy idea, but perhaps it would work as a last resort.

See this or this video (warning, loud music).

Solution 3

Remove the DIMM RAM... Remove EIO devices... Check that the formatter is secured... See if it starts working properly... If so, put the stuff back in until the failure reappear.

If all fails... It could be a faulty formatter, but this is very unusual.

I'd say you posted this in exactly the right place.

can't upgrade. during upgrading process loses connection and get the error on the display of the printer. also tried a cold reset. same thing. during upgrade i get a service error

Have you actually read the question? Or did you stop after reading the error code?

[Jan Marek]

I'm so sorry about that. I've tried to change my answer to fit better @JPHellemons needs...

[JP Hellemons]

No problem, have not tried to start the printer without network connection. But I think that it will be ok then and that the error will occur after a small task or at several percent of a big task (like firmware update)

[Jan Marek]

I recommend you to upgrade firmware though...

[JP Hellemons]

Hi Jan, I have the feeling that the error will occur again and that the upgrade is impossible. the only reason that i wanted to upgrade the firmware was because of the returning service error

[JP Hellemons]

ok, but i could not upgrade through web interface and also not by a manual upload with ftp

[Tom O'Connor]

I've looked everywhere I can for that firmware. It does appear to have been removed from the HP FTP site. I suspect this is because it's now totally End of Life, and End of Support.
