Defining the Backfeed Control Packet
Use the backfeed control packet (G) to enable or disable the
backfeed option, set the dispense position and the backfeed
distance. Backfeed works by advancing each printed label to the
desired dispense position. Once that label is removed, the next
label to be printed is backed up underneath the printhead. In
continuous mode, only the last label in the batch is advanced to
the dispense position. You may need to adjust the dispense
position to allow labels to be removed, die cut labels to be
removed easily, or to prevent them from falling off.
Extended backfeed is available on 9835, 9840, or 9850 printers
with a knife installed. Extended backfeed feeds a tag far enough
out to be cut and backfeeds the next tag to the printhead line.
Extended backfeed eliminates printed tags
being left between the printhead and knife.
Extended backfeed does not work with
non-indexed (continuous) supply/mode.
Do not use backfeed (normal or extended) with supplies less than
0.75 inches. We recommend using 0.5-inch gap supplies in peel
mode when backfeed is disabled.
The 9403 and 9805 printers do not support the backfeed
packet. (The 9805 automatically backfeeds in peel mode.) The
dispense position and backfeed distance are optio nal parameters
and do not have to be specified. However, they allow for greater
precision when positioning the supply. You can’t change the
backfeed distance while the printer is active.
