Chapter 5 Operating the JF-2418UV

NOTICE:

The factory setting of the height between print media and print head is 1.5mm.

If the height between print media and print head is more than 2mm, it may cause ink droplet

misting or splashing and lead to a grainy and uneven printing.

When the height between print media and print head is more than 2mm, the reflected light from

UV curing lamp increases and it can cause the misting ink to be cured, increase the ink visocosity

and nozzel clogging, and hence damage print heads.

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.
