Loading Roll Media
All of the ZD620 and ZD420 4 inch Link-OS printers load print media rolls the same. The printers support
the three basic types of media:
• Continuous (receipt, etc.) with no marks to define print length,
• Marked media (black lines, black marks, notches, or holes) to define print length
• Label media that uses the sensor to look through the media backing (liner) to see the beginning and
end of labels on the roll.
The printer utilizes two (2) sensing methods to accommodate a wide range of media
• Center area transmissive sensing for continuous media and gap/web label media.
• Full-width movable (reflective) sensing for print format (length) using black marks, black lines,
notches or holes.
Setting Media Sensing by Media type
• For web/gap media, the printer senses the differences between the label and the liner to
determine the print format length.
•
For continuous roll media, the printer only senses the media’s characteristics. The print
format’s length is set by programming (driver or software) or the last stored form’s length.
•
For black mark media, the printer senses the beginning of the mark and the distance to the start
of the next black mark to measure the print format length.
•
For other common media and setting variations, see one of the following:
• Using the Label Dispenser Option after you have loaded media using this procedure.
•See Printing on Fan-Fold Media.
