Epson TM-L90-i Technical Reference Guide

 Transparency rates are measured by the Macbeth TD-904 (with a filter for infrared) pho-
tometer. The transparency rates are calculated as follows:
Use
Density = Log10 (Amount of irradiation / Amount of transparency)
Then,
Transparency rate (%) = (Amount of transparency / Amount of irradiation) x 100
 If the transparency rates are out of the specified range (label + backing paper: 18% or
less, backing paper: 47% or more), the printer detects a layout error. However, paper
identified with a layout error may be used when the detection hole is prepared as follows.
The position to detect the label may be shifted by approximately 0.5 mm {0.02"}.
