HP Printer 49.xxx Service Error

HP Printer 49.xxx Service Error

Case 1: This is a critical firmware error. It relates to the EIO card, the firmware DIMM, or the formatter. I have found it to be a difficult error to pin down. Since you recently purchased it, it should still be under warranty. You may want to disconnect this from your network and connect directly to a PC to do some test prints. If it works ok that way, then there is a software conflict of some kind. The last time I ran into this, the company I work for ended up replacing our customer's 4250N with a 4250 and a JetDirect card. That solved their problem. Again: You should be under warranty, so call HP or your local authorized warranty center and they should take care of you.

Case 2: On the third call to HP support I got a savvy lady who immediately corrected our '49' errors.
This may or may not apply to you if I am to assume you are on a Windows system, since we are all Mac here. The simple solution for us was to turn off the RAM disk on the printer. That's it. No more errors for us. Hope that helps. Note: to switch off the RAM DISK - in the Printer control panel, select menu> Configuration>System Setup submenu of the Configure Device menu on the control panel.

Case 3: I recently purchased the 4250 and found that printing large documents with graphics required more memory. Added memory, and when I did the printer would go through all the diagnostics and come up in the ready mode. Upon reading the response to disable the RAM Disk - I tried it, and now my 49 FF04 Service Error is gone (I hope for good). Why would adding memory cause a conflict with the RAM disk?

Case 4: Hi all, we spent nearly 3 days trying to find a fix for the 49.FF04 service error. After endless searches and hours of troubleshooting, we found the problem. We are college and have over 300 printers. The problem started on Monday with 3 printers, and by Wednesday it was up to 15. They were numerous types of HP printers. In trying to find a fix, we took one of the printers and isolated it to a hub. I connect a computer to that hub and then installed Wire Shark (free sniffer). We watched the packets being sent. Right before the printer would die, we noticed that a DHCP NAK packet had been sent. From within Wire Shark, we were able to see that the packet came from a personal router that had been plugged into our network. The router was trying to hand out DHCP, this somehow killed the printers. We removed the router from the network and our problem was solved.

Case 5: In the technical support of the new firmware of HP4250/HP4350 usually has solution for problem 49xx

Case 6:
A critical firmware error has occurred that caused the processor on the formatter to abort the operation. This type of error can be caused by invalid print commands, corrupt data, or invalid
operations. In some instances, electrical noise in the cable can corrupt data during transmission to the printer. Other causes include poor quality parallel cables, poor connections, or specific software programs. Remove all EIO devices and firmware DIMM if installed. Restart printer. If error is gone replace each EIO device until error appears. Replace device which triggers error. May also be formatter.
Firmware updates are available for some machines at http://hp.com and clicking on the drivers and software tab. Also try printing from a different application. If that works go back to the first application and try printing a different file to determine if the problem is file related. You may need to reseat the memory DIMM's or replace the firmware DIMM or formatter board.
