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 so that it will be a reminder for myself the next time that it happens.
After removing all the parts, I received the 10.00.01 SUPPLY MEMORY ERROR which indicated to me that the client needed to replace their genuine HP ink cartridge and as soon as I installed the replacement, both error messages went away and the print jobs came out so now I have learned that the genuine HP ink that is bought in bulk to save then stored for months to years can develop issues even though they remained sealed in their product box.
