Error 49.38.07 Error (4A04) on Laserjet M551

[pstacy]

One of our printers recently started getting an "49.38.07 Error (4A04)" message during bootup.  I have downloaded the latest firmware to my PC but I don't know how to install it.  There are no USB ports on the printer to plug a thumbdrive into.  I accessed the printer configuration through Internet Explorer but I'm not seeing any way of uploading the firmware.

Thank you for any assistance.

It was found there was a corrupted print job in the queue.  Once cleared it started functioning again.

I also found I was able to get in to the Administrator console better with Chrome than IE.  In Chrome I could see where to upload the firmware, but the firmware file I downloaded from HP was corrupted and would not unzip.  Fortunately I didn't need it as somehow the printer is showing the current version.  I don't know when that was installed since I commonly work on the equipment where this printer is and I didn't do it.  Oh well!

I just finished dealing with this error code on our HP M551dn printer. The problem had to do with the installed HP toner cartridges.

To solve this issue I needed to access the printer's error log. This can be done by first inserting a USB flash drive into the printer's USB slot. (Our slot is a component on the formatter board so it required sliding out the board in the back with the network plug.) When everything is back together power on the printer and keep pressing the "Cancel" button until the LCD shows the pre-boot menu. From there select "3:Administrator", "B: System Triage", "1:Copy Logs", and "Accept/Download". With the "Accept/Download" option checked, back all the way out to the first menu and select "1:Continue". The printer will then write logs to the USB flash drive.

Remove the USB flash drive and bring it back to your own computer. You will discover it has written a file called "HPLogs.zip" in an "HPLogs" folder. Open this zip file and under "MachineData/log" you will find a file called "error.log". This file can give you details on the real problem behind the "49.38.07 Error" message. In my case it said:

The dump above is saying that the MagentaCartridge1 is saying its "Percent Life Remaining" is "-128". (We leave our cartridges in the system until the text fades.) The newest firmware doesn't expect that value and crashes, hence the "49.38.07 Error" message. After replacing the magenta toner cartridge, the error went away.

Hope this is a help to others in my situation.

I also had the error 49.38.07 on the LaserJet M551.  I took a posters advice that recently replied to this post, except I had a different issue.  The printer would show the error code on initial boot.  I reboot the machine in tandem with hitting the cancel input as it came on until the admin screen loaded.  

At some point a power outage knocked out my firmware.  I used the admin function to clear the disk fully.  I then uploaded the most recent firmware from HP here: 

http://h20565.www2.hp.com/portal/site/hpsc/template.PAGE/public/psi/swdHome/?javax.portlet.begCacheT...

After the printer accepted the new firmware it booted fully with no errors.

The USB port sits atop the printer.  It is in front of the grey platform that is the size of a CD case on the front right of the printer.  Just remove the built in dust cover and it will magically appear.  You must upload the firmware from the admin menu as well.

Hello,

Clearing the print jobs did it for me. Thanks for all your help.
