Top 20 Datamax M-Class Thermal Printer Questions & Answers

Hold in the Feed button for 4-5 seconds, which causes the printer to attempt to "Auto-calibrate." If that doesn't solve it, then slide out the Media Sensor (green plastic bar that sticks out over the labels) about 1 inch from all the way in ("in" = left if looking from front). Then press Feed to clear errors. If still get same error, then look for piece of label or ribbon stuck in that error - ok to blow out with canned air. Then try holding in Feed again for 4-5 seconds to Auto-calibrate again.

These printers do not "heat up" as such. Possible causes are:

1. Incorrect ribbon type for fitted ribbon spools. Look at back plate and see which way arrows are pointing. If arrows point Anti-clockwise, then you require inside wound ribbon (i.e. standard datamax) If pointing clockwise then you require outside wound (i.e. Zebra type ribbon). Check ribbons by touching sticky side of label to ribbon (it will transfer ink to label on print side).

2. Could also be faulty printhead, Logic board or Power supply. These will require an engineer to check properly.

Free Windows Printer Drivers for Datamax can be downloaded here: Custom Design Label Systems from Able Label Systems Look for the link toward the bottom labeled "Free Thermal Printer Drivers."

check the printer itself there are some problem inside

Yes, you can use the print preferences to configure the Mclass printer depending on the settings you want to make. You can change the print speed, heat, and even send commands to the printer if you wanted to. However, a much better solution to make changes in the printer to download the Datamax Printer Configuration utility from here: ftp://ftp.datamaxcorp.com/dmxConfig/Datamax%20Printer%20Configuration%20Utility.exe . This allows you to make changes in the printer without the need to use the buttons in the front panel. Hope this helps.

Hello,

The way you can do this is to use Datamax fonts in your LabelMatrix program instead of truetype fonts like arial or times new roman. After making this change, do a test print and see if print improves. Another possible solution is use USB instead of Parallel cable (if you're not using it already).

Review the media loading instructions in your owner's manual.

You've likely overlooked something.

Service documents refer to calibration. It is a known issue. https://www.google.com/search?q=Datamax+O%27Neil+Mark+II+printer+prints+2+labels%2C+then+skips+one+label ..

I need more information. What system are you using to drive the printer with? If it is a Windows computer it is almost certain to be a faulty/outdated driver.

Have you calibrated the printer with the supplies in it?

You need to replace the motor and the PSU.

You can get labelling software such as nicelabel or bartender. They will call the info on the excel and print them out.

Most likely this has a ribbon, check the settings for how low before warning. http://www.datamax-oneil.com/assets/maint_manual/I-Class_M2_Maint.pdf go to page 39

Not sure what kind of Datamax you are looking at, but you would need to change that via the software that you are using to create the labels.

Your program is most likely sending codes the printer does not understand. Try a test page from your driver if that works check the settings in your program. If it fails the driver test print you may have the wrong driver installed.

Font size is regulated by the document written and the software used to write the document..

There's a "Media Sensor" in the Datamax that is evidently having trouble seeing the labels. The sensor is inside of a horizontal bar above the labels and just behind the Printhead. That bar is movable. Make sure that the vertical mark, usually white, is positioned over the label - best if it is the center of the label. Also make sure that there is no label or ribbon material stuck in that area. Hold "Feed" button down for a few seconds after checking those two things to "Re-calibrate" the sensor.

It's called "Present Distance" and it can be set to "0" in the printer's control panel. Look under Print Control.

Remove the metal cover by removing the screws along the bottom left edge and one in the rear top right corner, and loosening the ones at the hinge in the top center. Then remove the screw on the media sensor, and pull the ribbon cable out of it's socket. The sensor slides out from the circuit board side of the center plane.
