Encoder Resolution
The encoder resolution is expressed in stripes (pulses) per mm and can be set to be-
tween 2.8 stripes / mm and 150 stripes / mm.
The standard SmartDate 5 encoder has an idler wheel of 52.5 mm mounted on a 500
stripes per revolution encoder. This gives an encoder resolution of 3.05 stripes / mm.
Encoder Setup
The idler wheel typically runs on a rubber roller and in the case of the SmartDate 5 has
a rubber tyre on the wheel. It is difficult to determine the exact measurements, therefore
the following procedure can be used to validate the setting.
1. Create an image containing one horizontal line.
2. Set the SmartDate 5 to fixed spacing mode by setting the Print trigger setting to 3.
Internal. (this can be found in the Engineering -Settings menus under Print Initiation)
3. Set the fixed spacing distance to 100 mm or greater.
4. Run the substrate at a constant speed and allow the printer to print a number of
prints.
5. Stop the substrate and measure the distance between the leading edges of the two
adjacent prints as shown below.
6. The distance should equal the configured fixed spacing distance.
7. If it is more than 0.5 mm out the encoder resolution should be adjusted.
