Do you have the USB connection direct into the computer, or via a USB port hub.
I had problems with my new X5150,which was doing funny things at various times.Would print/Wouldn't print,crashing,printing half pages etc.Lexmark eventually came up with the solution, of transferring the USB cable from my self powered USB hub, and installing direct into the computer USB port. Everything as been okay since. Should add that I un-installed and re-installed Lexmark software, both from supplied cd and downloaded from internet, without success, on first troubleshooting exercises.
If you have an hub connection, then perhaps worth considering above.No guarantees given.
Hi, just to show the other side of the coin, I have had an X75 for 12 months and have never had any problems printing (touch wood) and used the original driver on the CD. Suggest you go to Start/ Settings/ Printers. Double click your printer name. Click Printer tab/ Properties/ Details tab/ Spool Settings tab. Check that the spool settings are OK and that the Spool Data Format is set to LEMF.
