can I use the ink cartridges from a x1270 and install it into a z730?

According to Lexmark's website (http://www.lexmark.com/lexmark/product/supplies/home/0,7280,204816596_653399414_0_en,00.html), the cartridges are not interchangeable. The x1270 (an all-in-one) uses cartridge numbers 16, 17, 26, 27, while the z730 (a printer only) uses cartridge number 1.

Hope this helps,
