5.1.2 How To Set PH Gap Auto Adjustment Mode
The PH Gap Auto Adjustment mode:
It is suggested to set the settings to be “ ON ” (the default setting). Turning on the PH Gap Auto
Adjustment mode provides the fastest way for users to start printing on the media of which the
surface may be not flat or even, and the definite highest position of the media for AMC cannot
easily be found. Also, it protects print heads from being scratched by automatically adjusting the
print heads to optimized position when obstacle is detected.
When the setting of PH Gap Auto Adjustment Mode is “ON”:
If there is obstacle being detected, three steps can be applied,
1. Cancel job: cancel current job and redefine the highest position of the media for AMC to obtain
the best printing quality.
2. Continue to print by the mode set in FlexiPRINT: The print quality may be decreased, because
the print head gap is not the optimum value.
3. Continue to print by uni-direction: The throughput may be decreased and the quality may be
slightly affected, because the print mode is forced to set to uni-direction and the print head
gap is not the optimum value.
Under the following conditions, the PH Gap Auto Adjustment Mode can be set to OFF for
advanced users,
1. The media is flat or the highest position of the media for AMC is easily to be determined .
2. High print quality is high priority :
The platen will not automatically be adjusted to optimized position and the print job will be
canceled when obstacle is detected. The optimum print head gap defined by AMC is a critical
element for printing quality especially when performing bi-direction printing.
3. High throughput is high priority :
The laser beam scanning speed is faster when the setting is OFF than it is ON, and the default
print mode (bi-direction) will not be changed for higher printing speed.
