How to use only black cartridge on cx7450 epson !
Hi, this is not a solution because I don't think there is one apart from buying new inks. You need to consider 2 things, firstly the official line: Epson (and all other inkjet manufacturers) do this to prevent the coloured print head nozzles from getting blocked. If they are not used for a long time the ink dries up and blocks the nozzles. Epson recommends printing at least once a month with all colours to prevent this. Whenever the printer is turned on it performs a head clean, this is why the coloured inks get used over time even though they are not used for printing. It is also why the "print in Black only" option (available on some printers) only works when the coloured inks are OK.
The 2nd unofficial line is that it is a win-win situation for manufacturers. Firstly they get to cut down on costly warranty call outs for blocked heads (replacement printers, technician manhours, etc) and secondly they get to sell lots more inks (Ka-ching!). If you really want to print black text only (and save cash on price per-print) then a mono-laser printer is the best way as they can now be bought at inkjet prices.
