The HP Smart Tank 615 Wireless All-in-One (Y0F71A) is a colour ink tank printer for home offices and small businesses that need to print, copy, scan and fax at a low cost per page. Instead of cartridges it uses refillable tanks filled from spill-free, resealable HP GT53 black and GT52 cyan, magenta and yellow bottles; HP quotes up to 6,000 black or 8,000 colour pages from a set of bottles, and an automatic ink sensor warns before a tank runs low. Print speeds are up to 11 ppm black and 5 ppm colour (ISO), with black print quality up to 1,200 x 1,200 rendered dpi and borderless printing for photos and flyers. A 35-sheet automatic document feeder speeds up multi-page copying, scanning and faxing. Dual-band Wi-Fi (2.4 and 5 GHz) and the HP Smart app allow printing and scanning from phones, and a 2.2-inch touchscreen handles setup and Smart Tasks shortcuts. It is supplied with starter ink bottles.
