How To Use The
LF700
To Cut Different Coloured Media.
Each LF700 machine is setup to read black printed registration marks on white label stock, each OPOS
sensor can also read slightly differently but is checked that it reads within an allowed tolerance.
If you require the sensor to read anything other than the black reg mark on a white media then some setup
changes will have to be made.
Please follow the steps below:
1 Check the OPOS reading values. Do this by loading the coloured media into the
LF700
and position the
reg mark directly under the OPOS sensor. Press the ‘Menu’ button and go to ‘System Setup’ then ‘OPOS
Sensor. The screen will give you a OPOS reading, ensure that the sensor is lowered, then move the cutter
head on the Y axis by hand over both the printed reg mark and the un-printed media. Record the values.
2 Restart the
LF700
. Press ‘Menu’ ‘System Setup’ then ‘CAL Media’ select ‘Set’ and record the value.
The CAL Media value is the is the point at which the cutter will recognize the OPOS sensor read value as a
reg mark, as the sensor passes over the reg mark the read value will increase. The CAL Media value is the
trigger point. The value set as default is 100, this is multiplied by 8 to give the trigger point value of 800.
e.g.. if your sensor is reading the plain media at 270 and the reg mark at 1984 then the trigger point will be
270+800=1070 this value is easily inside the reg mark read value of 1984. This will give you a successful
reg mark read.
If the plain media read value is much higher e.g.. 1256 then 1256+800=2056 this will be greater then the reg
mark read of 1984 so the trigger point will not be reached.
Changing the ‘CAL Media’ setting will improve reading the reg mark on none white media, but will require
you to re-calibrate the OPOS.
Problems In Reading Registration Marks.
If the OPOS sensor has been misreading and is reading the mark printed sporadically.
If you have cleaned the sensor using compressed air and window cleaner on a clean room cloth, but it hasn’t
had any effect.
This following procedure should be performed to get an accurate reading of what the machine believes is the
difference between a black mark and white media.
1. Press the menu button when on the main screen (shows the speed and knife pressure).
Press the up button to show ‘SYSTEM SETUP’ it shows ‘DIN A4 TEST’
Up button to show ‘OPOS SENSOR’ this option enables you to manually move the cutter head over the
reg mark with the OPOS lowered to the media, this will give you the read value of your sensor.
It is a good idea to try this on several reg marks to find an average value for both the black and while areas.
Be aware that media will play its part in the values being read.
