SAFETY WARNINGS
[1] MODIFICATIONS NOT AUTHORIZED BY KONICA
Konica controllers for copier are renowned for their high reliability. This reliability is achieved through high-quality design and a solid service network.
Print controller units design is a highly complicated and delicate process where numerous mechanical, physical,
and electrical aspects have to be taken into consideration, with the aim of arriving at proper tolerances and
safety factors. For this reason, unauthorized modifications involve a high risk of degradation in performance and
safety. Such modifications are therefore strictly prohibited. the points listed below are not exhaustive, but they
illustrate the reasoning behind this policy
PROHIBITED ACTIONS:
• Using any cables or power cord not specified by Konica.
• Using any fuse or thermostat not specified by Konica. Safety will not be
assured, leading to a risk of fire and injury.
• Disabling fuse functions or bridging fuse terminals with wire, metal clips,
solder or similar object
• Disabling relay functions (such as wedging paper between relay contacts).
• Disabling safety functions (interlocks, safety circuits, etc.) Safety will not
be assured, leading to a risk of fire and injury.
• Making any modification to the print controller units unless instructed by
Konica

■ Product overview
● Capabilities of the Network Interface Card
The Network Interface Card allows to connect the print controller to a computer network. It receives
print jobs from the network and converts them into image data (video data) via print controller that
the copying machine prints out.
The network interface card is characterized as follows.
• Automatically selects 100Base-TX (Fast Ethernet) or 10Base-T.
• Supports peer-to-peer printing on TCP/IP and IPX/SPX from Microsoft Win-
dows 95/98.
• Supports printing by LPD/LPR of Microsoft Windows NT/2000.
• Supports both of Novell NetWare bindery mode and Novell Directory Service
(NDS).
• Incorporates an HTTP server and enable to be accessed through a standard
web browser to manage the printer and the network card. Management Ac-
cess Program (MAP) assists you to select a printer that will be displayed on
the web browser by indicating the list of printers on your network.
• Use of flash memory allows to upgrade the firmware via the network.
This Service Handbook describes hardware construction, procedures of installing/removing the
network interface card to/from the print controller, troubleshooting, and appendixes (installing
firmware, setting jumpers on the network interface card, etc).

■ Resetting the network interface card to Factory Default
You can cause the network interface card to restore all parameters to factory default values, so the
Network Interface Card appears just as it came from the factory. You may choose to do this when
the Network Interface Card is moved to a new location where the environment (NetWare file servers,
IP subnets, and so on) is different.
This process is called “Restore Factory Defaults”. It can be done with a Web Browser. However, if
network access is not possible, another method described in [Chapter 4 Appendices]-[Jumpers] is
available.
Resetting to factory default means that the network interface card loses all data
such as names and IP address. It does not lose its serial number and MAC ad-
dress.

Chapter 3 Troubleshooting
■ How to Diagnose Problems
Use the following list to determine the cause of printing problems:
1. Does the LCD panel of copier display an error message? Review copier INSTRUCTION MANUAL.
2. Is the printer printing? Make sure the printer is operating properly by causing it to generate a test
page. See your printer’s User’s Guide for instructions on generating a test page.
3. Is the printer on-line (green LED should light) about 2 minutes after power-on ? Verify that the
printer is on-line. Nothing will print if printer is not on-line.
4. Did you get a network interface card status page? On power-up, the network interface card
sends a status page which contains information that can be useful for troubleshooting. Keep the
status page available until a problem is resolved.
5. Check the status report to see what protocols are enabled and active. See the appropriate
chapter to confirm that you have installed and configured your network protocol correctly for the
network interface card. See An example of Status Page.
6. Check the network interface card’s LED status indicator to ensure that there is no error condition.
See LED Status Indicator, for more information.
7. Determine if other users can print. If they can’t and they are all on the same NOS, go to the
troubleshooting section for that NOS operation manual.
8. When you have determined the nature of the problem, use the checklists in the next section.

Chapter 3 Troubleshooting
● Troubleshooting Network Hardware Connections
• For 100BaseT or 10BaseT, check that the network connector is plugged into the RJ connector on
the network interface card.
• Try another cable to make sure you do not use a defective cable.
● Troubleshooting MAP Problems
If the MAP cannot detect a target network interface card, check the following:
• Are the network settings on the network interface card correctly made?
• Did you correctly select the MAP settings?
• Are the protocol used by the computer on which the MAP to run correctly set up?
• Are the Web browser used by the computer on which the MAP to run correctly set up?
• If nothing irregular is found, turn off the main power supply to the copier, then turn it back on, wait
about several minutes and try running the MAP again.
● Troubleshooting NetWare Protocol
It is recommended you use MAP to get the NetWare setup and parameter values. If you have not
resolved the problem after running MAP, go through the checklists in this section.
● NetWare Checklist
• Is the print server name entered correctly? The factor-default name is KON_serial number. The
serial number is located on the network interface card.
• Did you set up print queues to the printer? It is recommended you assign each print queue to
only one Network Interface Card-connected printer. If print queues are assigned to other network
printers, the print jobs may be going to another network printer.
• Did you set up the printer to the type Remote Other /Unknown?
• If the PCONSOLE or NWADMIN settings are correct, the connection between the printer and
network may have been broken. Turn the printer off and, using PCONSOLE or NWADMIN, wait for
the status message Not Connected. Turn the printer on and the status should change to Waiting
for Job.
● File Server Checklist
• Is there enough disk space on the file server and is it running?
• Is the correct file server associated with the printer? Use PCONSOLE or NWADMIN to check this.
• Did you have the proper rights to configure the printer? (supervisor or administrator)
• Are the File Server and the network interface card communicating? Run NetWare’s COMCHECK
utility from any network workstation to check this.
• Are there enough user positions on the File Server? The Print Server function logs on as a user.
3-6 Network Interface Card
Page 30
Chapter 3 Troubleshooting
● Workstation Checklist
• Is the network loaded onto the workstation? See the NetWare documentation.
• Is the application set up to print to the printer? For instance, are you using the correct driver?
• Is the workstation connected to the correct print queue? Print a file and verify that the file goes to
the queue.
• Are the print queues assigned to the network interface card-connected printer also assigned to
another network printer? If they are, the print jobs may be going to that printer.
• From PCONSOLE or NWADMIN, enter a sample print job directly into an assigned queue. Does
the job become Active? Is job printed?
• Is AUTO ENDCAP enabled? Auto Endcap lets you send data to a network printer. Use PRINTCON
to check. If not, enable it.
● Network Interface Card Configuration Checklist
If all your hardware connections are correct, check the following:
• Use MAP to check the status of the network interface card. The Unit Status screen shows the
status for the selected network interface card. This report includes a status of file servers and
queues assigned to a printer along with a description of any problems.
• The printer may not be assigned to the correct print queues. Use PCONSOLE or NWADMIN to
direct print jobs to the correct queues, then check to see if the print job is in the queue.
• If devices were added or changed, use PCONSOLE or NWADMIN to make sure you configured
the new devices correctly.
• Make sure the network interface card’s name has been entered correctly. If you changed the
name with MAP, you must also change the name in PCONSOLE or NWADMIN before you can
print.
• Use PCONSOLE or NWADMIN to check the Printer Status. Make sure it is not stopped.
• You cannot PCONSOLE or NWADMIN Version1.0 to configure the network interface card. Con-
nect Novell corp. for an upgrade.

● Printer Server/File Server/Printer Checklist
Check the following to see if:
• If the Print server cannot log in to the file server, or if it is not available to process jobs from the file
server, please check the followings.
• Check to see whether the Print server is configured to the file server. Set to it by using PCONSOLE
or NWADMIN if necessary.
• The password assigned to the network interface card through PCONSOLE or NWADMIN matches
the password assigned through web browser. Use web browser to update the password stored in
the network interface card’s memory.
• The print job is in the print queue and waiting to be printed. Use PCONSOLE or NWADMIN to
check if the print jobs are being sent to the printer.
● Workstation to Network Interface Connection Checklist
To make sure the workstation is communicating with the network interface card, check the following:
• Print a file from the workstation and make sure the print job gets to the print queue using PCONSOLE
or NWADMIN. If the print job does get to the queue, the problem is not with the workstation/print
server connection.
• Use CAPTURE to send data to the printer from a workstation software application. See your NetWare
print server manual for information.
• Make sure another printer is not taking the print jobs from the queues BEFORE the network interface
card can service the job. To do this, disable the other printer until you can verify the network
interface card-connected printer setup.
● The Network Interface Card Loses Its File Server Connection
If the network interface card loses its connection to the file server, it can take approximately 5 to 10
minutes to reconnect. If the connection is not made after a reasonable amount of time, check the
error conditions to troubleshoot the problem.
● Unable to Print from a Different Context
The network interface card does not support printing from a context different from the context you
are installed upon. If you want to do this, you must create an alias queue. See your NetWare Manual
for more information.

■ Rewriting the firmware
As the network interface card uses flash ROM, KN-302 and KN-302A is possible to rewrite the
1
firmware via the network.KN-306 is possible to rewrite the firmware via the parallel port.
● Rewriting the firmware via the network (KN-302/KN-302A)
To rewrite the firmware, you use the utility program FTP Download (for TCP/IP) by the procedure
described below.
● Preparation
• Set up the following components (IBM PC/AT-compatible Windows PC) for the environment of
TCP/IP.
• Computer used to upgrade the firmware
• Network Interface Card
• Install the network interface card properly and connect its Ethernet port with a network cable
so that the network interface card can be accessed from the network computer.
• The following utility should be installed on the computer.
• FTP Download
• Prepare the replacing firmware in the hard disk of the computer or in a CD-ROM.
● Procedure of rewriting the firmware
1. Make sure of the current firmware version.
You can get the information from the status page.
2. Start FTP Download and select the firmware file (.upd file) to download from [File] menu.
<Example> g15900a.upd
You will then be urged to enter the IP address and password.
3. Enter the printer’s IP address (e.g. 192.102.51.100) and the password “sysadm” and click
the OK button.
File transfer starts.
4. When a message “Unit Updated” appears on the computer screen, click the OK button.
Caution:
Never turn off the copying machine while updating is going on.
5. Turn off the copier and wait for 10seconds, then restart it.

● Rewriting the firmware via the parallel port (KN-306)
1
To rewrite the firmware, you use the utility program FTP Download (for TCP/IP) by the procedure
described below.
● Preparation
• Before going on, make sure of the settings the parallel port to [ECP] mode in the computer
(IBM PC/AT-compatible Windows PC)’s BIOS (This check is made on the BIOS Setup screen.
Refer to the operation manual for your computer.)
• Prepare the replacing firmware in the hard disk of the computer or in a CD-ROM.
● Procedure of rewriting the firmware
1. With the copier switched off, remove the network cable, connect a parallel cable between
the computer and the Print Controller.
2. Turn the copier’s main power on, output the Status Page and make sure of the current
firmware version.
3. Press the [MODE] button on the operation panel to switch to Printer Mode Basic screen.
4. Open a DOS prompt on the computer and input a copy command then press the Enter key.
<Example> C:\>copy firmware.xxx lpt1 /b
The message [Updating print controller F/W. Please leave the printer untouched.]
will appear on the LCD panel.
Caution:
Never turn off the copying machine while updating is going on.
5. The message [Updating Successful! Power off and restart the system.] will appear on the
LCD panel, turn off the copier and wait for 10 seconds, then restart it.
6. Output the Status Page to make sure that the firmware has been successfully rewritten.

KN-302 / KN-302A/KN-306 Network Interface Card
Caution:
The board for the network interface cards is common in the 302 and 306 products.
But their CPUs differ from one another. This means that rewriting the firmware
does not eliminate incompatibility between the network interface cards for the 302
and 306 products.
