This can be adjusted by using the button on the front panel to change the parameters as the printer prints.
●
If the lighter line is in the negative column, increase the compensation of the substrate advance.
●
If the lighter line is in the positive column, decrease the compensation of the substrate advance.
Nonetheless, this is a temporary setting and the compensation will disappear when the current job is
finished.
In order to introduce a permanent correction for the current media, proceed as follows:
Latex 360: A straight line in the diagnostic plot usually means that OMAS has been disconnected.
●
If the media is suitable for OMAS (backside of the substrate is not glossy), make sure OMAS is enabled in
the RIP print mode.
●
Unload the media, and clean the
OMAS on page 399.
●
Reload the medi,a and reprint the diagnostic plot. If the line is still not centered, add the value of the
lightest column to the current advance compensation factor in the RIP print mode.
Latex 330 / 310: Add the value of the lightest column to the current advance compensation factor in the
printmode at the RIP. This value may seldom have to be adjusted if TUR is used, relative humidity has a large
variation, different lots of media and /or aging of the printer.
If the advance is not a straight line, this would indicate that the printer has a variable advance error.
If this is the case verify the following:
●
Clean the
OMAS on page 399 and repeat the diagnostic plot (Latex 360 only).
●
Check the pinchwheels for missing rollers or deformations.
●
If the problem persists, calibrate the drive roller.
●
Perform the
Scan-axis check on page 197 (Scan Axis Calibration).
Advanced printhead health test plot
The advanced printhead health test plot is not part of the large diagnostic print, but it is similar to the
printhead health test plot described previously. With this plot, however, you will be able to identify which of
the printhead nozzles is actually failing. To print this test plot, go to Menu List > 2.4 Printheads Health > 2.4.2
Print Advanced Test Plot.
