New Printhead Print Head for Zebra GX420D GK420D ZP450 ZP550 ZP505 ZP500 Printer 203dpi PN 105934-037

Used this to replace the printhead on our GK420D thermal printer that was going out and this makes the printer print like new again. The print quality actually looks a tad sharper now. Easy to install, just look up on Youtube, took less than a minute to swap out.

Not an installation for the faint of heart - be bold and you can do it! Put the printer on its back, mouth open. Find the piece that looks like this part and pop up the little plastic lever by one side of it. The print head will now be loose. Wriggle it out gently, paying attention to how it was in there. Disconnect the two tiny strip connectors and replace with the new unit. You will need a thumbnail or probe to get them loose. Careful which side goes up. Be sure both sides are slid all the way in. Slip the head back in until it clicks. Press down on it to make sure it feels like it is on springs. Not so bad, huh?

Works as designed

It skips and gets stuck to label, causing a big waste. It worked perfectly for the first 5 or 6 labels then it didn't.

These are a lighter print than the standard OEM ones but are a good price. If your customers are okay with the light print these should not be a problem. Easy to replace and good fitment for the wires when they connect. No issues yet and are much cheaper than OEM.

Simple YouTube video from zebra changed it in seconds great fix for reasonable price.

Brought the Zebra printer back to life!

Works great. I just put it in, turned it on and starting printing.
