When you do repairs and deal with clients that are owners of printers manufactured by HP, you will eventually get a call for a 49 Error. One that I get so frequently that I walk the client through it over the phone without checking the Knowledge Base is the 49.0665 Error but on this occasion, the client reported a 49.38.07 Error (4a04) and since there are not a lot of articles and videos on it, I am going to detail it here.

After I arrived, I remov as much moving parts as I could to see if it was a sensor issue and received the 10.00.01 SUPPLY MEMORY ERROR which indicated that the client needed to replace their genuine HP ink cartridge. As soon as I installed the replacement cartridge, both error messages went away and the print jobs from the previous night came out so it was unnecessary for me to have to look up how to access the Preboot Menu on HP Printers on this service call to flash any firmware.

* HP LaserJet Enterprise M600 M602
* HP LaserJet Enterprise M806
