5.9.5 Double half fold setting
After finished paper data setting (chapter 5.5), go to the folding data setting.
Choose the double half fold; its icon will appear in the fold type. And the
preset data will automatic setup. For example, the paper of 420mm long will
need folding line 1: 105.2mm (420/4+0.2 = 105.2mm, the +0.2mm is thickness
compensation calculate with 0.2mm paper thickness, and this value will
change with thickness); folding line 2: 211.2mm (420/4*2=210mm, the
+1.2mm is thickness compensation); folding line 3: 316.4mm (420/4*3
+1.4=316.4mm, the +1.4mm is thickness compensation). The roller position
will setup, too. Those value can be changed manually. User can change roller
position to other value (such as 105mm), as long as the product in the outfeed
area will not crash next product and still be pressed by the outfeed roller
smoothly. For the Shingle, it will change the distance that the second sheet
stack on the first sheet. Larger value make two sheets far away; smaller value
make two sheets closer. Click return button after finished setting, the data will
show up in the screen. Then, user can go to run screen for the job.
Note: Sometime, the folding lines’ value is changing base on real situation
(thickness, filming, and printing else), it might not be exactly half of the length.
The value for roller position and shingle is same ideas, they might need to
change with the real situation. For example, the following photo shows that
the first sheet has about 30mm distance away from the outfeed exit. Then,
second sheet can outfeed normally without crash.
