Monarch printer 9420 supply problem

Here's a video that shows how to properly load supplies into the gun. It's possible that the supplies aren't loaded properly..

Were the new labels thermal paper? Thermal printers need specially made paper to work right.

If you are not using ribbon, the tickets are probably not Direct thermal. Try using a Ribbon and see if it works

Seagull would likely have to provide the real help here, but it sounds like your Seagull drivers are not using the correct supply setting. If the supplies have a black mark on the back of the liner, then set your driver up as black mark. If they ONLY have a small gap between the labels, then set it up as die cut. If it has a die cut and a black mark, set them up as black mark.

It is also possible that your sensor is dirty, damaged, or covered up so that the printer cannot see the supplies. If you're not using Monarch/Paxar/Avery Dennison supplies, then the index mark (die cut or black mark) may not be to the printer's specification and it just doesn't know when to start and stop on a label.

101 : The format referenced by batch isn't in memory. (Try rebooting printer or closing/opening software)
005: Supply width is invalid. (Check your format data)

You have a bad printhead. Shut off the printer and as it reboots check out the display. It'll probably flash "765 printhead error" as it boots up.
The printhead needs to be replaced.

change the fonts of the printer by pressing the font button on the panel (Refer user manual for more details)

check the alignment of the sensor.
If continuous, make sure dip switches are set to continuous.
There are particular settings for a die sut, and continuous label

one side of the paper will be sensitive to heat and the other side won't be. If it is thermal paper run a pen without the actual ink part sticking out of the pen or use a key from your key ring in your pocket over the paper the friction should leave marks on the thermal side of the paper.
you may have the paper in with the non thermal side facing the heat printing part of the paper. Or you have the wrong paper.

ld4028-10a or ld21084 may be the label ? not sure its 40 mm wide not 55 mm or 2.2 inch

plz try by reinstalling the drivers then check the ink status
