Jet substitution allows a better performing jet to be used in place of a missing or poorly performing neighboring jet. When jet substitution mode is used, the printhead makes a second right-to-left movement to deposit the pixel columns of the substituted jets. See "Jet Substitution Mode" on page 6-12. Ink Loader The ink loader consists of four parallel channels with an ink melting element at the end of each channel. Ink sticks, one color loaded in each channel, are pressed by coil spring pressure into the melting elements. As ink is required by the printhead, the appropriate color's melting element is activated and the end of the ink stick is melted. The melted ink drips into the ink reservoirs of the printhead underneath. Sensors in the ink loader alert the customer to install more ink sticks before the current sticks are completely consumed. If the ink level sensors inside the printhead detect that the printhead has run out of ink, but the ink low/out sensors are not activated, the control panel reports an "Ink Jam" error.
