The colorimetric sensor is on the left side of the carriage unit and its main functions are as follows.

  • Calibration
    The machine can print and scan the color measurement chart to perform color measurement. The results can be used for calibration and creating color profiles in the RIP.
  • Non-ejection nozzle detection
    The machine can print and scan a nozzle check pattern to detect non-ejection nozzles. The detected non-ejection nozzles are registered in the machine so that the machine can print by substituting the non-ejection nozzle with a different nozzle. Detection/registration/substitution of non-ejection nozzles can be executed from [Maintenance] - [Clogged Nozzle Settings] - [Auto Nozzle Check] / [Registering Clogged Nozzle] / [Nozzle Recovery].
  • Measurement of ink misalignment (sub scan direction)
    The machine can print and scan a pattern for media feed adjustment to measure the amount of ink misalignment in the sub scan direction. The machine automatically adjusts media feed amount based on the result. Measurement and automatic adjustment of ink misalignment (sub scan direction) can be executed from [Print Adjustment] - [Media Feed Adjustment].
  • Measurement of ink misalignment (main scan direction)
    The machine can print and scan a pattern for print head gap adjustment to measure the amount of ink misalignment in the sub scan direction. The machine automatically adjusts the positions of ink drops based on the result. Measurement and automatic adjustment of ink misalignment (main scan direction) can be executed from [Print Adjustment] - [Drop Position Adjustment].

  • Print Head Alignment/Media Feed Correction
    Adjust print head alignment/media feed correction to reduce image quality defects such as black lines and white lines as well as variation in concentration.
    Print head alignment can be adjusted from [Print Adjustment] - [Selected Setting for Head Alignment] - [Print Head Alignment].
    Media feed correction can be adjusted from [Print Adjustment] - [Selected Setting for Head Alignment] - [Media Feed Correction].
