The Lexmark 17 tri-colour ink cartridge is one of the correct replacement cartridges that will work in your Lexmark Z640 printer. However, please be aware that the Lexmark 17 is a light-user ink cartridge so it will only print up to 140 pages. This is based on printing at 5% coverage of an A4 page so if you're printing full colour sheets then the actual number of pages that you'll print will be considerably less and you'll need to factor this in when trying to calculate how many prints you get from the cartridge. We recommed that if your Lexmark Z640 colour ink is runnning out too quickly you should order the Lexmark 26 high capacity tri-colour ink cartridge which can also work in your Lexmark Z640 printer. The Lexmark No. 26 high capacity colour cartridge is more economical and long-lasting, allowing you to print up to 300 pages and will deliver a cheaper cost-per-print than the light-user Lexmark No. 17 colour cartridge.

Yes, the Lexmark 17 and 27 ink cartridges are light user cartridges but you can also use the high capacity Lexmark 16 and 26 black and tri-colour cartridges in your Lexmark Z640 printer instead. The only difference between them is that the Lexmark 16 and 26 cartridges contain more ink, hence the difference in price. Any cartridge listed on this page will work reliably in the Lexmark Z640 inkjet printer. As long as you have one black and one tri-colour cartridge installed, it's possible to use any combination of these cartridges, regardless of whether they are light user or high capacity ink cartridges.
