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.
00:00 – 49.38.07 Error (4a04).
00:10 – Removing all consumables.
00:30 – Testing the printer sensors.
01:00 – HP LaserJet 600 M602.
01:50 – Close top cover sensor message.
01:55 – Tray 2 open sensor message.
02:00 – Install Black Cartridge sensor message.
03:38 – 10.00.01 Supply Memory Error
After I arrived at the client, I removed as many consumable parts from the printer as I could to see if it was a sensor issue and received the 10.00.01 Supply Memory Error during troubleshooting which indicated that the client needed to replace their genuine HP ink cartridge due to a bad sensor on the 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 during this service call to flash any firmware.
