Media Detection

Media detection in EPL2 printers is a combination of programming and printer media sensing. The Q (Set Form Length) and O (Option) commands program the media detection method. The user must configure the printer for the media type and the (programmed) form or label in use.

The printer can detect the beginning and end of the printable area on the media by one of three methods: gap, notch (hole), or black line. The gap method detects the difference in optical density of a label on a liner from the liner only with the transmissive (gap) sensor. The notch method uses the transmissive sensor to detect a hole in the media (gap-less labels or tag stock). The black line method uses the reflective sensor to detect a preprinted black line on the media back (for gap-less labels or tag stock).

Printing on continuous media requires programming to control media positioning.

EPL2 printers also support a “Label Dispense” mode as a printer configuration option (for most models). The printers use a “Label Taken” sensor to detect the removal of a label.

One or more of these sensors may require user adjustment or configuration for proper operation. All EPL2 printers have an AutoSense feature to optimize label and label gap detection by the transmissive (gap) sensor. See the printer’s user manual for printer specific sensor adjustment control.
