Calibrate The Printhead - Oce Colorado 1640 Operation Manual

Calibrate the printhead

Introduction
When you are unsure about the density of colors on your printed output, you can optimize the
printhead performance. Perform a printhead calibration when you want to optimize colors.
NOTE
• You can only perform printhead calibration when you print without winding. For more
information, see
• You have to use a smooth, white, opaque, non-reflective media for the printhead calibration.
• You have to use a media type that can be used for printing without winding.
Procedure
1. On the operator panel tap on the [Tools] icon on the right.
2. Tap on [Printhead calibration].
3. Select the roll you want to use for calibration.
4. Tap on [Start].
The printer performs the calibration.
NOTE
The calibration can take quite some time, around 30 minutes. Wait until the printer is
finished with the calibration. When the active job disappears and [Start] is no longer
greyed out, the calibration is finished.
After you finish
The calibration can be successful or it can fail.
When a message appears that the calibration has failed, perform printhead calibration again.
When the calibration fails again, perform automatic maintenance three times without automatic
nozzle optimization. For more information, see
Perform printhead calibration again.
When the calibration is still not successful, contact your local Service representative.
