Printing with Externally Mounted Roll Media

Printing with Externally Mounted Roll Media

The GC420 printer accommodates externally mounted roll media similar to the printer’s support of fan-fold media. The printer requires the media roll and stand combination to have a low initial inertia to pull the media off the roll.

Zebra at this time does not offer an external media option for the GC420 printer.

Externally Mounted Roll Media Considerations:

•The media ideally should enter the printer directly behind the printer through the fan-fold media slot in the rear of the printer. See Printing on Fan-Fold Media on page 38 for media loading.

•Lower the print speed to decrease the chance of motor stalls. The roll typically has the highest inertia when trying to start the roll moving. Larger media roll diameters require the printer to have more torque applied to get the roll moving.

•The media should move smoothly and freely. The media should not slip, skip, jerk, bind and then move, etc. when mounted on your media stand.

•The printer should not touch the media roll.

•The printer should not slip or lift up off the operating surface.
