hello,

 

ive bought the dell 720 printer, it was working fantastically until recently. Now when I try and print this message appears: Communication not available. The printer cannot communicate with the computer. Try these solutions: Disconnect and reconnect the usb cable. Disconnect and reconnect the printer's power cable. Restart the computer.

 

Ive taken out the usb cable and put it back in and the same with the rest, it then works fine but then goes funny again. All the cables are in and correctly in the right place. ive just printed 2 pages and Im now not able to print anymore.

 

please help asap

thanks

emma
