SAFETY PRECAUTIONS
[1] Installation Environment
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. Most electrical equipment is safe when installed in a normal environment. However, if the environment is different from what most people consider to be normal, it is conceivable that the combination of the machine and the room air could present a hazardous combination. This is because heat (such as from fusing units) and electrical arcs (which can occur inside switches) have the ability to ignite flammable substances, including air. When installing a machine, check to see if there is anything nearby which suggests that a potential hazard might exist. For example, a laboratory might use organic compounds which, when they evaporate, make the room air volatile. Potentially dangerous conditions might be seen or smelled. The presence of substances such as cleaners, paint thinners, gasoline, alcohol, solvents, explosives, or similar items should be cause for concern. If conditions such as these exist, take appropriate action, such as one of the following suggestions.
·

safety margins for mechanical, electrical, and electronic aspects. It is not reasonable to expect individuals not involved in product engineering to know what 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. For these reasons, installation of any modification not specifically authorized by Konica Business Machines U.S.A., Inc., is strictly prohibited. The following list of prohibited actions is not all-inclusive, but demonstrates the intent of this policy.
· · ·

Using an extension cord or any unauthorized power cord adapter. Installing any fuse whose rating and physical size differs from that originally installed. Using wire, paper clips, solder, etc., to replace or eliminate any fuse (including temperature fuses). Removing (except for replacement) any air filter. Defeating the operation of relays by any means (such as wedging paper between contacts). Causing the machine to operate in a fashion other than as it was designed. Making any change which might have a chance of defeating built-in safety features. Using any unspecified replacement parts.

· · · · ·

Determine that the environment is controlled (such as through the use of an exhaust hood) so that an offending substance or its fumes cannot reach the machine. Remove the offending substance. Install the machine in a different location.

· ·

[3] General Safety Guidelines
This machine has been examined in accordance with the laws pertaining to various product safety regulations prior to leaving the manufacturing facility to protect the operators and service personnel from injury. However, as with any operating device, components will break down through the wear-and-tear of everyday use, as will additional safety discrepancies be discovered. For this reason, it is important that the technician periodically performs safety checks on the machine to maintain optimum reliability and safety. The following checks, not all-inclusive, should be made during each service call: CAUTION: Avoid injury. Ensure that the machine is disconnected from its power source before continuing. v

The specific remedy will vary from site to site, but the principles remain the same. To avoid the risk of injury or damage, be alert for changes in the environment when performing subsequent service on any machine, and take appropriate action.

[2] Unauthorized Modifications
Konica has gained a reputation for manufacturing reliable products. This has been attained by the combination of outstanding design and knowledgeable service forces. The design of the equipment is extremely important. It is the design process that determines tolerances and

· · · · · ·

Look for sharp edges, burrs, and damage on all external covers and the machine frame. Inspect all cover hinges for wear (loose or broken). Inspect cables for wear, frays, or pinched areas. 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 machine -ensure continuity. An improperly grounded machine can cause an electrically-charged machine frame.

[5] Applying Isopropyl Alcohol
Care should be exercised when using isopropyl alcohol, due to its flammability. When using alcohol to clean parts, observe the following precautions:
· ·

Remove power from the equipment. Use alcohol in small quantities to avoid spillage or puddling. Any spillage should be cleaned up with rags and disposed of properly. Be sure that there is adequate ventilation. Allow a surface which has been in contact with alcohol to dry for a few minutes to ensure that the alcohol has evaporated completely before applying power or installing covers.

· ·

[6] Summary
It is the responsibility of every technician to use professional skills when servicing Konica products. There are no short cuts to high-quality service. Each machine must be thoroughly inspected with respect to safety considerations as part of every routine service call. The operability of the machine, and more importantly, the safety of those who operate or service the machine, are directly dependent upon the conscientious effort of each and every technician. Remember...when performing service calls, use good judgement (have a watchful eye) to identify safety hazards or potential safety hazards that may be present, and correct these problem areas as they are identified -- the safety of those who operate the copier as well as those who service the copier depend on it!

[4] Safeguards During Service Calls
Confirm that all screws, parts, and wiring which are removed during maintenance are installed in their original positions.
·

When disconnecting connectors, do not pull the wiring, particularly on AC line wiring and high voltage parts. Do not route the power cord where it is likely to be stepped on or crushed. Carefully remove all toner and dirt adhering to any electrical units or electrodes. After part replacement or repair work, route the wiring in such a way that it does not contact any burrs or sharp edges. Do not make any adjustments outside of the specified range.

INTRODUCTION

INTRODUCTION
The IP-302 is an image processor that connects the model 7060 copier to a computer or computer network, allowing it to be used as a printer. The image processor receives files from the computer or network and translates them into images to be printed on the copier/printer. Features and specifications are given in the introduction section of the controller's User's Manual. A video interface kit must be installed to connect the IP-302 to the 7060. Detailed instructions are given in the installation section of this manual. This section also provides instructions for installing the optional PostScript® upgrade kit and the network interface cards available for the IP-302. Other information included in this manual are: product configuration; disassembly and assembly procedures; troubleshooting tips; and an appendix section that includes software installation and CMOS setup instructions, motherboard jumper settings for setup verification, and various tables containing error messages, beep codes, and copier codes to assit the technician while troubleshooting. This manual is to be used as a supplement to the 7060 Service Manual. Note: The IP-302, KN-101/KN-201 User's Manuals are not included in this publication.

INTRODUCTION

Start-up Process
When powering up these units, the initialization can be made in either sequence: turning ON the IP-302 first or turning ON the 7060 copier/printer first. The start-up process is as follows (in this case, turning ON the IP-302 first): 1. Turn the IP-302 ON. The CIC (copier interface card), which interfaces with the printer, starts up. The CIC indicates to the printer that it is running and then waits for the printer to power up. The CPU in the IP-302 tests the system memory and then boots up. 2. Turn the copier ON. It sees that the IP-302 is connected and running, and goes into the printer mode. 3. The CIC and the printer establish a link. The CIC initiates transfer of configuration information.

4. After the system memory is tested (this will take a few minutes), DOS boots up and then the system software loads. 5. When the system is fully configured, READY is displayed. Printing may begin. When a document is sent to be printed, the following process takes place (see the diagram on page 1-3): Data enters the IP-302 through the Ethernet card or one of the I/O ports. The I/O controller software evaluates and spools the data to either the PCL-5E interpreter or the PostScript® interpreter. The interpreter then generates an image into memory in bitmat form, which then travels through the CIC to the printer.

IP-302 SOFTWARE INSTALLATION GUIDE
This guide is a step by step procedure for initializing and loading the system software onto the IP-302 hard disk. The system software is available for PCL-only systems and systems with both PCL and PostScript®. These disks can be installed without using a keyboard and monitor; however, the use of a keyboard and monitor is recommended. Each of the 6 disks is a self-contained module that installs one section of the system software. When reinstalling the system software, always use the latest available version. It is not necessary to install each newer version on top of the older ones. Note: If a replacement hard disk of a different size or type is installed, or if the system software has never been installed, run the CMOS setup program. This will require the use of a keyboard and monitor. A special system disk will also be necessary. This disk can be obtained from Konica's Digital Support Lab. 1. Installation with no keyboard and monitor Note: This setup procedure is for upgrading or reinstalling the system software that is currently loaded. a. Insert disk 1 (system) in the disk drive of the IP-302. b. Press the red reset switch or turn the power ON. The system will perform its memory tests and then boot from the diskette. This may take a few minutes, depending on how much memory is installed in the IP-302. c. When the contents of disk 1 have been installed, the IP-302 will emit a series of beeps. Remove disk 1 and place disk 2 in the drive; then, press the reset button. Repeat this operation for each disk. Note that the disks must be installed in order. d. When the last disk has been installed, remove the disk from the drive and press the red reset button. Note: If at any time the IP-302 emits a steady tone instead of a series of beeps, an error has occurred during the installation. At this point the use of a monitor will be necessary to determine the cause of the error. Refer to 3. Troubleshooting. 2. Installation with keyboard and monitor attached. a. Insert disk 1 (system) in the disk drive of the IP-302. b. Press the red reset switch or turn the power ON. The system will perform its memory tests and boot from the diskette. This will take a few minutes depending on how much memory is installed in the IP-302. The following message will appear on the monitor: "Waiting 30 seconds to execute SETUP.BAT. Press any key within 30 seconds to cancel and get to an A:> prompt." · If a new hard disk has been installed or the system software has never been installed, the drive must be partitioned. To do this, press any key; then, type INITDISK and press enter. INITDISK runs the DOS FDISK program and automatically selects the correct options. When it is done, it will automatically reboot the IP-302. The message described above will be displayed again. At this point, the IP-302 will launch the setup program after 30 seconds. · If the hard disk does not need to be partitioned, simply allow the IP-302 to launch the setup program. c. The setup program copies the files from the system disk to the correct locations on the hard disk and configures the IP-302. When the contents of disk 1 have been installed, the IP-302 will emit a series of beeps, and a message will appear on the monitor. Follow theinstructions displayed on the monitor. Repeat this operation for each disk. Note that the disks must be installed in order. d. When the last disk has been installed, remove the disk and press the red reset button. Note: If at any time the IP-302 emits a steady tone instead of a series of beeps, an error has occurred during the installation. Refer to 3. Troubleshooting. 3. Troubleshooting a. If the hard disk that the software is installed on has already been partitioned and INITDISK is run on it, the IP-302 will lock up. To correct this, press the reset button. Do not run INITDISK. b. If INITDISK has not been run, the hard drive was not partitioned correctly, or has become corrupted, the disk will not format correctly. Run INITDISK. If that fails, run the DOS FDISK program to remove the corrupt partition, or replace the drive. c. When the drive is formatted, any bad sectors on the disk will be masked so that they will not affect the operation of the drive. If certain sectors in the beginning of the disk are bad, the drive is not usable. Replace the drive. d. If during installation the IP-302 displays a DOS error message such as "Error Reading Drive A:, Sector not found" or a similar message, the installation disks may be bad. Obtain another set of disks and try again. If the problem persists, there may be a problem with the IP-302 disk drive or controller.

IP-302 MOTHERBOARD DO'S AND DON'TS
Here are some general guidelines when work involves the motherboard.

Inserting SIMMs
Refer to the service manual for inserting SIMMs. SIMMs are keyed via a slot cut in the bottom of the module. If the SIMM rocks from side to side, do not force it into the socket; try turning it around.

CMOS settings
Before removing the motherboard, enter the CMOS setup and write down the hard disk parameters for the number of cylinders (tracks), heads, and sectors. Also, note the preComp and landing zone values. Some new motherboards don't have auto-detect features that determine these settings; writing them down is very important.

Using the right tools
Do not use a screwdriver to remove the nylon standoffs from the motherboard. One slip can easily damage trace lines. Use a small needle-nose pliers to compress their "wings" about a millimeter above the board; then, carefully slide them out.

Power down
Turn the system OFF, and unplug it. It is easy to accidentally turn the power ON when moving the unit around.

Labeling the cables
Label the key lock, speaker, reset, turbo, and any other cables that are removed from the motherboard.

Power supply
The main power supply connectors are always installed on the motherboard so that the black wires in each connector are next to each other.

Ribbon cables
When reattaching disk drive ribbon cables, note that a colored stripe (usually red) marks the #1 wire. Also, disk interfaces typically have the #1 position printed on the interface board or motherboard. If removing the cable from the drive, remember that the #1 wire is always on the same side of the connector as the power cable.

Keep the board level
Keep spare nylon standoffs on hand. Old standoffs can become brittle and can easily break when being removed. Make sure that both new and old standoffs have the same height at the base. If the motherboard is tilted even slightly, there may be difficulty inserting add-on cards later.
