meters (6.6 feet) in length.
(2) Check that the printer cable is not damaged or broken. Check also that the printer cable is
connected to the correct interface connectors of both the machine and PC.
(3) If an interface switching device is used, remove it and connect the computer directly to the
machine and try again.
(4) Check that the appropriate printer driver is selected as ‘Set as Default’. Check also that the
correct print port is set for the selected printer driver.
(5) Check that the machine is not connected to the same port which is also connected to a mass
storage device or scanner. Remove all other devices and connect the port to the machine only.
Turn off the printer status monitor in the device options tab in the printer driver.
(6) If the print port is set as an ECP port, change it to a normal port.
(7) Try printing the test page referring to
