Black and composite color average per bottle (cyan/magenta/yellow)
results based on HP methodology from the simulation of continuous
printing of ISO/IEC 24712 test pages. Not based on ISO/IEC 24711 test
process. An additional black ink bottle is required to print 8,000 color
test pages. Actual yield varies based on content of printed pages and
other factors. Some ink from included bottles is used to start up the
printer. For more information about fill and yield, see
