First of all, on Dymos you need to use original Dymo roll,.

Dymo rolls have a tag at the back, non original ones does not have it.

Before reinstalling driver you also need to run the dymo uninstaller utility that you find at Dymo website.

I will post the links for download.

Hi, I solved this by doing a "cleaning roller" (dont know the right word in english) from the settings -> maintenance menu of the MP640. Good luck!

You have to tell the laptop to use an external display this usually involves pressing the FN + F5 on and acer but does vary from laptop to laptop

the second key usually has two screens printed on it

have u installed the drivers before pluging i the printer but try this after unintalling the drivers

Try this website, it is pretty good about scanning and fixing cd/dvd errors.

you must change the port of the printer,to usb port and not for network port.

Normal 0 Could have a corrupt driver.
Disconnect the printer or at least be sure it is turned off. I'd do both and when the CD software program asks you to connect the printer to the USB port, do so and it should again work properly.
Hope this helps. Bud

USE DIFFERENT PORT FOR PROBLEM OCCURED HARD DRIVE AND CHECK SAME PROBLEM CONING TO THAT PORT ALSO .THEN THE PROBLEM IS WITH YOUR HARD DRIVE .REPLACE IT.
