Zebra G-Series printers

Media handling

1.The default media action of the G-Series printers resembles that of an EPL-based 28-series printer: the printer will not feed automatically at power-on, only following a lid closure. If you are changing between two different styles of media, you should carry out a manual calibration. This can be achieved via the printer’s two-flash Feed-button sequence. The printer can be changed to feed at both power-on or lid closure using the ZPL ^MF command.

2.The G-Series printers are easier to load than 28-series printers because they do not have separate roll holders and guides. They are one integrated element and support 12mm/0.5" cores.

3.If using fan-fold media or an external media roll, the centralised thumb wheel can be used to keep roll holders open (as opposed to using the older screw-

down method). Rotate the thumb wheel inwards on the direct-thermal printers to keep the guides apart. For thermal-transfer printer guides, rotate the thumb wheel outwards to keep them apart.

4.For GX420 or GX430 printers equipped with a cutter option, its default operation is to double-cycle following every 25th cut. This automatic dual-cut is intended

as a cleaning action to maintain the life of the cutter. This action can be disabled via the appropriate SGD command “cutter.clean_cutter”, but it is

not recommended.

5.Providing the relevant option is installed, common media handling can be controlled via the SGD constructs. The “media.printmode” command can be used to manage G-Series printers in tear, peel or cutter modes of operation.

Power

1.The power supplies for the thermal-transfer G-Series printers (the GK420t, GX420t and GX430t) are located in the upper packaging. This is the same as 28-series printers. However, direct-thermal G-Series printers (the GK420d™ and GX420d™) have their power supplies located in the lower packaging beneath the printer itself.

2.The G-Series printers’ power supplies are of a 24-volt DC design, as opposed to the 28-series printers’ 20-volt DC design. Additionally, the power cable’s attachment to the supply itself – the line socket – is of a C13 “kettle” style, which is different from the C5 “clover-leaf” style of the 28-series. Power supplies and power cables are specific to printer models. G-Series printers cannot use 28-series printers’ power supplies and vice versa.

3.When looking at the rear of the G-Series printers,

the location of the power on/off switch is on the right. This is different from that of the 28-series.
