Chapter 6 Printer screen status indicators The printer screen has two status indicators: one for print cartridge status, and another for paper status. This indicator... Has this meaning... When the print cartridge status indicator is on solid (not flashing), the ink level is low. When the print cartridge status indicator is flashing, either the ink level is too low to print, or there is a problem with the print cartridge that needs attention. Make sure that you have inserted the correct print cartridges for the printer. For more information about which problem has occurred, connect the printer to your computer and read the instructions on the computer screen. If the ink is out on one of the print cartridges, the arrow on the printer screen will tell you which one to replace. When the print cartridge status indicator has a right arrow next to it, the right print cartridge needs to be replaced. When the print cartridge status indicator has a left arrow next to it, the left print cartridge needs to be replaced. When purchasing replacement cartridges, refer to the cartridge numbers that appear on the back cover of this guide. For more information, see Inserting and replacing the print cartridges When the paper status indicator is flashing, either there is a paper jam or the printer is out of paper. 38 HP Photosmart 7800 series
