CHAPTER 6 TROUBLESHOOTING

5.SOFTWARE SETTING PROBLEMS

The printer may not print the data correctly if there are incorrect software settings.

S-1

“There was an error writing to LPT1: (or BRUSB) for the printer” error message appears.

User Check

(1)Check that the printer cable is not damaged or broken. Check also that the cable is connected to the correct interface connectors of both the printer and PC.

(2)Check that the correct printer is selected if you have an interface switching device.

(3)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.

(4)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.

(5)If the print port is set as an ECP port, change it to a normal port.

(6)Try printing the test page referring to Subsection 10.1 ‘Test Print Mode’ in this chapter.

(7)Try resetting the factory settings.
