A:Answer Thank you for the question. Apologies, you'll need to purchase replacement ink bottles. The included ink is sufficient for 6,000 color pages (composite) and 8,000 black and white pages, based on an ISO standard of about 15% ink coverages per page. That equates to about a two year supply of ink. Printing of photos or other high-graphic files will use more ink than printing emails, etc. The following footnote applies to the Smart Tank 551 and was included on the box/packaging: *Based upon 200 pages per month usage. Actual yield varies considerably based on content of printed pages and other factors. Average based on ISO/IEC 24711 or HP testing methodology and continuous printing. Some ink from included bottles is used to start up the printer. For details see http://www.hp.com/go/learnaboutsupplies.
