Re: My Monarch Printer shows the error code 001 Res Load...

This is a format error. If you have an 001, it means that the Packet ID must be between 1 to 999.
A sample of what that code looks like...
The 1 after the F is the Packet ID.
If you don't actually use code to send to the printer, and rely on 3rd party software or drivers, you may need to go to that vendor since they're likely not sending down the data to the printer correctly.

Errors 001 to 405 and 429 to 435 are data errors. This type of error indicates that incorrect data was sent to the printer, and the printer is ignoring it. Your System Administrator should correct the packet and send it back to the printer. Error 411 is baud rate mismatch. Here's the manual:

Getting error code 956 on a monarch 9820 label printer. Any idea what this error code means?

Are you sure it's not a 756 error? 756 is a supply error, basically saying that you ave no supplies loaded. A 956 is an unspecific generic error code, saying you have a mother board failure.
The display on the 9820 is difficult to read. I'd say you have a 756 error.
Double check your dip switch settings and make sure they match the type of supplies you have loaded.

We have a 9855 Monarch barcode Printer. We are

If the printer display just shows Ready, but doesn't print, there could be a few things wrong.

1 - no data is going to the printer
2 - data is going to the printer, but it is not the printer's native language
3 - cable connectivity issues
4 - wrong cable is being used
5 - if wireless, data is not going to the correct IP

If using a 3rd party application, make sure that you've chosen the correct Monarch printer, as well as printing to the correct port. Sometime people print to LPT instead of Serial, as an example.

If using 3rd party drivers, make sure of the same thing.

To see if the printer actually works, press both of the arrows on the display, at the same time, after the printer is at the ready screen. As long as have the printer configured correctly (ribbon, supply type, etc.), the printer should print out a couple of labels.

Error code 754

It's very possible you are not installing the ribbon properly.
When loading a new ribbon on a Monarch printer, you must save the plastic ribbon core (it's butter yellow in color) from the previous roll of ribbon. The core is what the ribbon is wound up on.
Do not throw away this plastic core - you need it for the next roll of ribbon you load!
You have to move this now empty core from the back ribbon spindle and slide it on the front ribbon spindle. You then load the new ribbon on the back spindle and attach the ribbon end to the empty plastic ribbon core on the front spindle.
You CAN NOT just tape the ribbon to the front spindle. You must have an empty ribbon core to attach the new ribbon to. The printer will give a 754 error unless you have two plastic cores on the two spindles. It can also give a 754 error if the ribbon is not loaded properly, and also if you have a bad motherboard. There are no ribbon sensors, so that's never going to be a problem...
