Hi ,

when i try to print a jpeg file from a usb key,i got this message(A error occured due to an unknown reason).
I cannot print pdf files since the direct print and the ps options are not installed.

I tried with different usb keys and different jpeg files,the result is the same.
I have also tried with different usb location.
I have updated the machine with the latest firmware.
So, before proceeding to any "clear" on the machine,can someone who has ever encountered this issue give me some help.

Thanks in advance.
