How can i send an ascii file to a network shared Datamax Prodigy Plus printer? It is not printing via send file, windows driver send command to printer works. Thanks for any help!

copy file.txt lpt1 is the command to copy the txt file to the printer, but it must be correctly formatted for the Datamax. I don't know Datamax's programming language, but at first glance that file looks like ZPL to me. If it is ZPL the Datamax can't print it.

How to perform a quick calibration in a Datamax I-class printer

Before to perform a label calibration, check the label and ribbon are installed correctly. Also check the label sensor (the green piece above printhead) is in correct position and clean. To perform, press and hold FEED button and release after 5-6 seconds later. In display you can see CALIBRATION SUCCESS, if not, then do it again. Good Luck. Roberto Martinez.

I have a datamax I series and I would like to know how to troubleshoot the stepper motor

What type of problem do you have?
Will the printer not feed?
There has been some troubles on early model of the Datamax I class printers that are detailed in a service bullitin on the driver/power supply.
If the printer feeds intermittently, or runs back wards(hunts) it is probably a board failure. I usually replace the board and the motor on exchange with DAtamax if under warranty.

Position fault error

The Datamax I4308 returns a position fault error if it cannot sense the label gap where its supposed to be, or if the sensor returns a value outside the permitted range. Re-calibrate to correct the error.

Its worth checking that you are using the latest drivers. You should be able to get these from the Datamax website. Also check the printer set up, gap sensor etc. Also check the media is loaded correctly. Hope this helps. Regards Stu

Regarding Datamax E-4203 - Won't print

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.

Datamax problem

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