Hi, I am in Equatorial Guinea, Africa, i got a problem with our Printer HP CM6040. When i make a copy through the ADF,the trailing edge of the scan is cut by a half an inch,and also can someone tells me the pin number of the service menu for this printer. its like the ADF end of page sensor is cutting off after 10.5 inches instead of going the full 11 inches. Thank you for your help.
