Wanting to send HP an E Mail about my C4280 Photosmart all in one printer they asked for it's serial number. I found a number of reference numbers on the bottom of the machine but whichever number I quoted was said to be incorrect. Mine was a general enquiry so would have thought the model only would have been enough. Having tried several times I gave up! I am quite sure one of the numbers given was correct. Is this done to discourage enquiries?
Thank you braindead. I tried what you suggest and the print out it produced gave the serial number. I checked with HP and they still told me the number is on the machine but it isn't! However the number I got is correct so thank you very much. why are things always so complicated.? Don't answer that.
