The length between the leading edge of the sheet and the 1st crease position can be
calibrated in the event of the machine creasing out of position.
Also the last crease closest to the back of the sheet can be adjusted relative to the front
edge of the sheet to compensate for the inaccuracy of manufacture of the input roller
diameters.
The first crease should be 50 mm (2.00 inch) from the lead edge (less than 1 revolution
of the infeed roller) & the last crease should be 370 mm (14.50 inch) from the lead edge.
These figures match with the test sheet available from the production department.
Adjust the 1st crease position as follows:-
• Turn On machine
• Hold down the Push Button 4 and flick the Set-up switch down – the display will
show ‘dEtr’ and a numeric value of between 90 & 121.
• Rotate the setting dial to change the value (turn clockwise to Increase), a higher
value will move the crease further from the lead edge (105 is a good starting point).
• Return setup switch to ‘Ready to accept value.
• Run machine and check crease position – repeat above procedure until accurate
crease position is achieved.
Adjust the Last crease position as follows:-
• Turn On machine
• Hold down the Push Button 4 and flick the Set-up switch down – the display will
show ‘dEtr’, press push button 3 & the display will change to ‘Etch’ and a numeric
value of between -128 & +127.
• Rotate the setting dial to change the value (turn clockwise to Increase), a higher
value will move the crease further from the lead edge, (0 is a good starting point).
• Return setup switch to ‘Ready to accept value.
• Run machine and check crease position – repeat above procedure until accurate
crease position is achieved.
