User Check
(1) Check if the printer cable is not too long. It is recommended to use a parallel cable of less than 2
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 printer and PC.
(3) If an interface switching device is used, remove it and connect the computer directly to the printer
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 printer 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 printer 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 Subsection 10.1 ‘Test Print Mode’ in this chapter.
