Thanks Wolfeymole, Goku, Dalo Harkin and Plastic Nev, I have read and digested your suggestions and will act accordingly when my fresh Cr2032 arrives. Regards, Frank.

My computer help recommends me to save all my BIOS settings as I now need to replace the CMOS battery. There appear to the multiple pages of these found on F2. Are they all relevant, and do I need to record everything that shows? Your help would be appreciated before I spend ages needlessly making notes. Frank.

Thanks for your contributions RandyL and Dalo Harking; it looks as if HP has taken advantage of my innocence. Regards FL.

The spare cartridges I have are all HP21 (black) and I have tried the combinations that you suggest above which shows that they are all interchangeable from D1460 to D3940 but not vice-versa. The first thing I did before buying the D1460 was to check that these 21s fitted, so I cannot imagine what cause of the problem is. I do now notice however that the old ones are all date engraved 2008 (although I bought them in 2007) and the new working one 2009. That is the only difference that I can observe.

Thanks for your note RandyL. All these cartridges are original fills and they work fine on a Deskjet 3940, but they fail to print when I tranfer them to the new printer. I have installed this new machine from disc both with and without all the 'extras' but it makes no difference. Could there be some date identifier in the program which recognises them as antedeluvian?

I have just bought an HP D1460 printer mainly because I have several unused HP21 and 22 ink cartridges. Now I find there is a cunning device which prevents me using these - probably because of their age. The helpful message simply says 'there is a problem with the right hand ink cartridge' and of course fails to print. I can immediately replace the original cartridge and all is fine, but this is marked 'Introductory' so I suspect will not last long. Can anyone please say how I can disable this? Thanks.
