Zebra GK420 Series Reviews
Aug '17: 5/5 Stars The GK420 is the midline of label printers from Zebra. It is faster than the older 2824 and GC410 series, in a very compact and well built casing. The GK420 is available in a large variety of interfaces with USB/Ethernet being the most popular. The best thing going for the GK420 is compatibility, nearly all label printing and point of sale labeling modules were built to work with the Zebra desktop barcode printers. Compatible media is also the easiest to find out of all the desktop printers, from very small jewelry labels to large shipping labels the GK420 can print them all. Calibration is also very easy to do with a single control button the only thing you need to use. Thermal Transfer (ribbon) models are available for applications requiring a more permanent label.

Hi, Travis from POSGuys.com. Today we're going to go over how to calibrate your Zebra G-Series Desktop printers. So this applies to the GX420, GK420, GC420. There's several models that are in their desktop line that this applies to. Basically the ones that don't have an LCD screen and are the dark grey color. The lighter color white ones, the older ones, LP2824, LP2844, they have a slightly different process.
So by default this is the one button on here that you use to calibrate, if it shoots out multiple labels, it skips labels, or it's aligned in the middle of the label, you'll need to run a calibration. To do that, you'll hold down this button. It's going to flash once, then it's going to flash a double flash, and then it's going to flash a triple flash and then a quadruple flash. What you're looking for is the double flash. So you hold this down, you get a single flash, then it's going to be a double flash. That's when you let go. After you let go, the printer is going to spit off one label, maybe two labels, and it's going to be calibrated after that. Whenever you hit the button you should get one label spit out of it.
Right here I have black mark labels being used. If you're going to switch to a different label, like a shipping label with a gap instead of a black bar, you drop in your label and you hit the button. So that might happen, where it's not cleanly feeding out labels, you just go through the process one more time, hold down the button,it flashes once, then you'll get a double flash. After the double flash, you release and it's ready to go. You've switched from black mark labels to gap sensitive labels. So this applies to the calibration to the GX420, GC420 or GK420.
