HOME SAFETY PRECAUTIONS SAFETY PRECAUTIONS Installation Environment effect may be caused by altering any aspect of the machine’s design. Such changes have the potential of degrading product performance and reducing safety margins. Safety considerations usually are directed toward machine design and the possibility of human error. In addition, the environment in which a machine is operated must not be overlooked as a potential safety hazard.
HOME SAFETY PRECAUTIONS • Ensure that the power cord insulation is not damaged (no exposed electrical conductors). • Ensure that the power cord is properly mounted to the frame by cord clamps. • Check the continuity from the round lug (GND) of the power cord to the frame of the copier -- ensure continuity. An improperly grounded machine can cause an electrically-charged machine frame. Applying Isopropyl Alcohol Care should be exercised when using isopropyl alcohol, due to its flammability.

HOME Chapter 1 Overview ■ Product overview ● Capabilities of the IP-421 The Konica IP-421 print controller allows you to use the Konica 7020 series copying machine as a printer connected to computers and a network. It receives print jobs from computers and network and converts them into image data (video data) that the Konica 7020 series copying machine prints out. The IP-421 print controller is characterized as follows. * Built in the Konica 7020 series copying machine.
HOME Chapter 1 Overview ● Startup sequence of the 7020 series + IP-421 system As the IP-421 is built in the 7020 series, supplying power to the IP-421 and its initialization starts as soon as you turn on the copier. The startup sequence is as follows. 1. Turn on the copier. Supplying power to start the IP-421 starts. Its CPU works to test the system memory and the system program starts running. 2. The IP-421 performs system check. 3. On completion of system check, the controller is waiting print job.

HOME APPENDICES
HOME
HOME Chapter 4 Appendices ■ Upgrading the Firmware The IP-421 uses a compact flash ROM and you can go two ways in upgrading the firmware.You can update the firmware via a parallel port or you can replace the compact flash ROM. ● Rewriting the Flash ROM Normally, use this method. Preparation • Connect the IP-421 through a parallel cable to the computer that is used to upgrade the firmware. • Prepare the replacing firmware in the hard disk of the computer or in the form of CD-ROM.
HOME Chapter 4 Appendices A message indicates that the firmware is being rewritten. 4. On completion of firmware renewal, a message indicating the completion appears. Then turn off and on the Main SW of the copier. ● In case of failure in rewriting the firmware If rewriting the firmware fails for some reason, it may be possible to redo the rewriting procedure when the error happened in file transfer from the computer. Turn off and on the Main SW of the copier and try the procedure again.
HOME Chapter 4 Appendices ● Replacing ROM The firmware can be upgraded even by replacing the ROM. Replace the ROM if it is impossible to update the firmware via a parallel port. 1. Remove Flash card stopper plate on sub panel. 2. Remove Flash card. 3. Install Flash card. 4. Install Flash card stopper plate.
