At first my printer spit out labels very quickly. Now I find that we have to wait a long time for it to communicate. Once it starts to print it will only print a few at a time, stop to think, then print a few more. I am currently printing about 4,000...this is going to take awhile. Any suggestions? Thank you.

You probably need to adjust the leveling cam if you have not done so already. This is the green thumbscrew near the print mechanism.

You can adjust the display contrast by pressing and holding the MENU key for 10 to 20 seconds to modify the LCD contrast level.

Ended up being the heating settings - they were to low, so when I hit print...it would spit out a label but nothing would be on it.

Problem solved!

Check to see that the label sensor is over the gap in the label. It is just under the head on the right hand side.
You might also have the unit configured incorectly. If you go to the Datamax site, you can download the printer config program, It is easier to use than trying to push the buttons in the correct order to configure the printer.
Also use at least a 6" long label, and print the config file to see if you are set correctly for gap mode if using die cut stock.
