49.4c02 and 49.4c06 errors on LJ 4350s

Have recently upgraded around 30 LJ4350s to latest driver 61.074.561.43 and latest firmware. Now looking through the event logs on each printer we are getting these errors. Users are now starting to report having them and the only way to remedy is to shut off the printer and back on. Seems to be no rhyme or reason on when it will throw the error. Any suggestions? Going to PCL5, PS, are not options.. have to use PCL6 drivers.

Randy,
I hope you have better luck with this than I did with a CLJ 3800. I was getting a variety of 49.x errors from Day 1. HP tech support kept focusing on the software even though I told them it happens even doing paper path test with the printer disconnected from a pc. After a lenghty downtime (a couple of months), they relectantly agreed that the printer had a problem and sent me a new formatter (printer was still in warranty, fortunately).

In the EWS (web page for the printer), in the Networking section, Other Settings, Misc. Settings ... Turn off protocols (Enabled Features): mDNS, Multicast IPv4, and IPP Printing, perhaps also FTP Printing.

In the Network Settings, if you are not using IPX/SPX then turn it off. Do the same for AppleTalk unless it's being used (for your sake, I hope you're not using it).

Turning off these items usually stopped (or nearly stopped) those errors from happening for me.

Also, apply the newest Firmware for the printer as well (if using Web JetAdmin to apply the firmware, you'll have to turn on the FTP Printing to get it to apply).

Lastly, HP is correct to look at software. Bad print jobs easily cause this error so be sure the systems that use the printer have the newest drivers installed and that the drivers are working well.

The PS drivers are causing the same errors for us. Did you ever get a fix for this??? I saw someone mention there was a beta firmware available somehow, but I haven't been able to get HP to answer my question about that.

Please post something so that others (and I) will have an answer.

Thanks!

I haven't had any problems with the 49.4c02 errors with the print models they've listed (and I have several of each of those models under my responsibility) however I have had trouble with the 49.4c02 errors with the LaserJet 4345 MFP units we have.

In the case of the 4345 MFP units, we found that we could replace the entire machine and the problem location would continue to be a problem. Yes, something about the signals or impulses the machine encounters at the location have EVERYTHING to do with the problem ... but we were never able to figure out what the problem was.

We did find a workaround. If we downgrade the firmware to an older version, the 49.c02 errors disappear. We downgraded to a firmware with a datecode of 20080403 (April 2008). Haven't yet tried slightly newer firmwares (without doing the newest).

You may have a difficult time finding older firmware versions. I've been using versions I've accumulated over the past few years.

My LJ4350 printers are using firmware SPCL015A (datecode 20080819). My CLJ3800 printers are using firmware 46.040.2 (datecode 20080408) and 46.039.0. The LJ4345 MFP units are using firmware 09.111.1 (datecode 20080403).

In another thread (sorry don't have the link at the moment) a user reported that HP had informed them HP is in the midst of developing new firmware that will correct the 49.4cxx errors. Here's hoping.
