Safety

SAFETY WARNINGS
MODIFICATIONS NOT AUTHORIZED BY KONCA
Konica copiers are renowned for their high reliability. This reliability is achieved through high-quality design and a solid service network. Photocopier 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 degrading 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 extension cables or a different power cord than specified by Konica. Using other fuses than specified by Konica. Safety will not be assured, leading to a risk of fire and injury. Disabling fuses or bridging fuse terminals with wire, metal clips, solder or similar. (This applies also to thermal fuses.) Removing air filters (except for replacement). Disabling relay functions (such as wedging paper between relay contacts, etc.). Disabling safety functions (interlocks, safety circuits, etc.). Safety will not be assured, leading to a risk of fire and injury. (7) Performing actions to copier not described in the instruction manual or the service handbook. (8) Using parts other than specified by Konica.

(1) (2) (3) (4) (5) (6)

CHECKPOINTS WHEN PERFORMING ON-SITE SERVICE
Konica machines are extensively tested before shipping, to ensure that all applicable safety standards are met, in order to protect the customer and customer engineer from the risk of injury. However, in daily use, any electrical equipment will be subject to parts wear and eventual failure. In order to maintain safety and reliability, the customer engineer must perform regular safety checks. CAUTION: (1) Wear clothing that facilitates work and is designed for safety. (2) Carry out all procedures carefully to prevent injury. (3) Be sure to disconnect the power cord of the copier and all optional equipment from the AC outlet. Simply turning off the power switch is not sufficient, because paper feed units or other electrical equipment may be powered also when the power switch is turned off. (4) Proceed with special care when performing operation checks or adjustment while the unit is powered. When carrying out operation checks or adjustment while external covers are removed, the risk of electrical shock exists when touching parts which carry high voltage or electrical charge. The risk of injury exists when touching moving parts such as gears or chains. The following list is not exhaustive, but it includes actions which must be carried out at every service call. CAUTION: (1) Check external covers and the frame for sharp edges, burrs, or nicks. (2) Check external covers and hinges for loosening or damage. (3) Check wiring for squeezing or damage. (4) Check power cord for insulation problems (conductor must not be exposed). (5) Check power cord and cable ties etc. for loosening from frame. WARNING: (1) Verify that the copier is properly grounded. If a problem is detected, establish a proper ground connection. (2) Connecting the ground lead to an improper point such as listed below results in a risk of explosion and electric shock. Unsuitable ground points: - Gas pipe - Lightning rod - Telephone line ground - Plastic water pipe or water pipe or faucet that has not been properly grounded.

vi

Safety PRECAUTIONS FOR ON-SITE SERVICE
CAUTION: (1) Before performing maintenance work, read all relevant documentation (service handbook, technical notices, etc.) and proceed according to the prescribed procedure, using only the prescribed tools. Do not carry out any adjustments not described in the documentation. (2) If the power cord is damaged, replace it only with the specified power cord. If the power cord insulation has been damaged and there are exposed sections, short- circuits and overheating may occur, leading to a serious fire risk. (3) Do not route the power cord so that it can be stepped on or pinched. Otherwise overheating may occur, leading to a serious fire risk. (4) When disconnecting any cables, always grasp the connector and not the cable (especially in the case of AC and highvoltage leads). (5) Carefully remove all toner remnants from electrical parts, electrodes, etc. (6) Make sure that wiring cannot come into contact with sharp edges, burrs, or other pointed parts. (7) Double-check to make sure that all screws, components, wiring, connectors, etc. that were removed for maintenance have been reinstalled in the original location. (Pay special attention to forgotten connectors, pinched cables, forgotten screws, etc.) (8) When installation and preventive maintenance, verify that the power cord has been securely plugged into the AC outlet. Contact problems may lead to increased resistance, overheating, and the risk of fire. WARNING: (1) Before disassembling or adjusting the optical unit or any parts that use a laser, make sure that the power cord has been disconnected. (2) Do not remove the main cover of the write unit. Direct exposure of the eye to laser beams may lead to blindness. (3) Do not turn the copier on while the write unit is not installed in its normal position. (4) Danger of explosion if battery is incorrectly replaced, replace only with the same or equivalent recommended by the manufacturer. Discard used batteries according to the manufacture's instructions.

HANDLING OF MATERIALS FOR SERVICING
Drum cleaner (alcohol-based) and roller cleaner (acetone- based) are highly flammable and must be handled with care. When using these materials for cleaning of copier parts, observe the following precautions. (1) Disconnect the power cord from the AC outlet. (2) Use only a small amount of cleaner at a time and take care not to spill any liquid. If this happens, immediately wipe it off. (3) Perform cleaning only in an environment where sufficient ventilation is assured. Breathing large quantities of organic solvents can lead to discomfort. (4) Do not replace the cover or turn the unit on before any solvent remnants on the cleaned parts have fully evaporated. CAUTION: Toner and developer are not harmful substances, but care must be taken not to breathe excessive amounts or let the substances come into contact with eyes etc. If this happens, immediately rinse with eye wash and plenty of water, and consult a physician. CAUTION:

MEASURES TO TAKE IN CASE OF AN ACCIDENT
(1) If an accident has occurred, the distributor who has been notified first must immediately take emergency measures to provide relief to affected persons and to prevent further damage. (2) If a report of a serious accident has been received from a customer, an on-site evaluation must be carried out quickly and Konica Corporation must be notified. (3) To determine the cause of the accident, conditions and materials must be recorded through direct on-site checks, in accordance with instructions issued by Konica Corporation.

s Product overview
q Features of the IP-601
The Konica IP-601 is a print controller that enables the Konica 7075 Copier to be connected to a variety of computers or networks to be used as a printer. The IP-601 receives files from computers or networks and converts those files into image data (video data), so as to be able to be printed out using the 7075 Copier. To do this, a VI-601(video interface kit) needs to be mounted to the 7075. This service handbook provides information on product configuration, removal and installation procedures and troubleshooting. Appendices provide information on software installation, mother board jumper settings to be checked for, error messages, beep codes, and copier codes assisting service personnel in troubleshooting, among others. This service handbook is intended to be bound together with the 7075 Service Manual.

[1] IP-601 Software Installation Guide
This section provides information on how to initialize the IP-601 hard disk and how to load the system software onto the hard disk. When reinstalling the system software, be sure to use the latest version of it. Note: Before proceeding, be sure to turn off the 7075.

Suggestion: Run the CMOS setup program after having replaced the hard disk with one different in size or type or if the system software has never installed so far. To do this, the use of a keyboard or monitor becomes necessary. Also, dedicated system disks are required. Suggestion: This setup procedure needs to be followed when upgrading the currently loaded system software or when reinstalling it. a. b. Insert disk 1 (System) into the Floppy disk drive on the IP-601. Switch on power to the IP-601. A test will run on the memory under the action of the BIOS program, and the IP-601 will get started by starting up the hard disk. c. Upon completion of installation of the content of disk 1, a series of "pip" will sound. Then, take out disk 1, insert disk 2, and press the reset button. Repeat the process with each disk. Be careful not to go wrong in the order in which disks are to be inserted. d. Upon completion of installation of the content of the last disk, take out that disk, and turn the IP-601 off. Note : The number of disks required varies depending on updates.

Suggestion: To update BIOS, you need a keyboard and CRT. An updating procedure will be delivered each time it becomes necessary.

Chapter 4 Appendix [10] Handling IP-601 Mother Board
The following are general guidelines for you to follow when handling the mother board. Switching off power Turn the system off, and then remove the power cord plug from the IP-601. Otherwise, it may have a chance that the power is switched on accidentally during transport. Power Supply Unit The main unit connectors are required to be connected to the mother board so that the black line of each connector comes side by side. Board Height Always have a spare nylon stand at hand. An old stand is fragile and is likely to be damaged in the removal process. When replacing the stand, check to make sure that the height of both the old and new stands is identical. If the mother board tilts even slightly, plugging ad-on cards into the board gets difficult. Plugging in DIMM Modules When plugging in DIMM memory modules, refer to "Installation of DIMM Memory Modules" in the service handbook. The DIMM memory module is held in place by means of the cutouts in its bottom. If the module is loose and wobbly at the ends, do not push it in with force, but remove it and try again. Use Proper Tools Do not use a Phillips screwdriver to remove the mother board from the nylon stand. If you let the screwdriver slip accidentally, the board pattern easily scratches. Be sure to use a pair of pliers having tapered ends to hold the wing of the nylon stand at a height of about 1 mm off the board, and carefully take out the stand. Ribbon Cable When reinstalling the ribbon cable for the disk drive, make sure that the color (mostly, red) stripe-marked lead becomes the #1 lead. For the disk interface as well, the corresponding interface port or mother board is mostly marked #1. When removing a drive from a cable, be sure to always arrange the #1 lead so as to come on the same connector side as the power cable.
