This one is somewhat tough.
Most times when you get this error, you actually do have a printhead issue and you need to send the printer into their service department. If you're not printing a barcode, then these printers may show you this error, allow you to continue printing, but will print a grey box instead of barcode if there are bad dots falling within the barcode itself.
If the latter is your issue, sent it in. If the latter isn't your issue, you could potentially plug along without any worry until the human readable starts to get unreadable. Again, that would be the time to send it in.

This error occurs when the head has some damage. Check also that the head of the cable is properly connected.

The Monarch 9403 does not print out multiples of labels continuously, it stops between each single label. Can you help? Cheers Debbie


I may need a little more information.

If you are using a 3rd part software application like that from Loftware, you may need to create your labels in such a manner that the print module prints strips of labels, and in the quantity that you need. Then the printer should produce the quantity each time you go to print.

If you are using a 3rd party driver, like that from Seagull Scientific, then you need to tell it to print that quantity, just like you would when printing something on your inkjet printer.

If you are sending the printer's native language directly to the printer, there is something called the format header. It looks something like this:


The second 1, is the quantity of labels. So if you want it to print 5, you need to change it to something like...


If neither of these make sense, please provide some additional details so that I may provide further assistance.

If the printer doesn't react when you send a print job to it (either prints, or displays an error code on the display) and just sits there doing nothing, it generally means the print job didn't get to the printer. Check your communication settings. The printer comm settings must match the settings in your software. The default comm settings on the printer are:
Baud : 9600
word length: 8
stop bits: 1
parity: none
