Accordingly, KMBT does not warrant, either explicitly or implicitly, that the information contained in this Service Manual is complete and accurate. Therefore, this Service Manual must be carefully read before doing service work both in the course of technical training and even after that, for performing maintenance and control of the product properly. Keep this Service Manual also for future service. When servicing the product, the relevant works (disassembling, reassembling, adjustment, repair, maintenance, etc.) need to be conducted with utmost care. DANGER: Action having a high possibility of suffering death or serious injury WARNING: Action having a possibility of suffering death or serious injury CAUTION: Action having a possibility of suffering a slight wound, medium trouble and property damage Symbols used for safety and important warning items are defined as follows::Precaution when using the copier. General precaution Electric hazard High temperature:Prohibition when using the copier. General prohibition Do not touch with wet hand Do not disassemble:Direction when using the copier. Konica Minolta brand products are renowned for their high reliability. This reliability is achieved through highquality design and a solid service network. Product 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.

In that case, it is obligation of customer engineer (hereafter called the CE) to attach appropriate power plug or power cord set in order to connect the product to the supply. Use of inadequate cord set leads to fire or electric shock. S-3 SAFETY AND IMPORTANT WARNING ITEMS 3. CHECKPOINTS WHEN PERFORMING ON-SITE SERVICE Konica Minolta brand products are extensively tested before shipping, to ensure that all applicable safety standards are met, in order to protect the customer and CE from the risk of injury. However, in daily use, any electrical equipment may be subject to parts wear and eventual failure. Use of an adapter leads to the product connecting to inadequate power supply (voltage, current capacity, grounding), and may result in fire or electric shock. If current leakage occurs in an ungrounded product, you may suffer electric shock while operating the product. Connect power plug to grounded wall outlet. When securing measure is provided, secure the cord with the fixture properly. Check whether the sheath is damaged. If the power plug, cord, or sheath is damaged, replace with a new power cord or cord set (with plug and connector on each end) specified by KMBT. The cable may be broken, leading to a risk of fire and electric shock. Current that can flow in the extension cord is limited, so using a too long extension cord may result in fire. Do not use an extension cable reel with the cable taken up. A risk of fire and electric shock exists. In the case of an earthquake and so on, the product may slide, leading to a injury. Do not make any adjustment not described in the documentation. When the power plug is inserted in the wall outlet, some units are still powered even if the POWER switch is turned OFF. High-voltage exists around the drum unit. A risk of electric shock exists. Do not supply power with the write unit shifted from the specified mounting position. Dispose of the used lithium battery using the method specified by local authority.

A risk of fire exists.It may be stimulative. If the substances get in the eye, rinse with plenty of water immediately. You may be burned due to dust explosion. Drum cleaner (isopropyl alcohol) and roller cleaner (acetone-based) are highly flammable and must be handled with care. If this happens, immediately wipe it off. Breathing large quantities of organic solvents can lead to discomfort. S-10 SAFETY AND IMPORTANT WARNING ITEMS SAFETY INFORMATION IMPORTANT NOTICE The Center for Devices and Radiological Health (CDRH) of the U.S. Food and Drug Administration implemented regulations for laser products manufactured since August 1, 1976. Compliance is mandatory for products marketed in the United States. Since radiation emitted inside this copier is completely confined within protective housings and external covers, the laser beam cannot escape during any phase of normal user operation. When accessing these areas for maintenance, repair, or adjustment, special care should be taken to avoid burns and electric shock. For metric area: This product employs a Class 3B Laser Diode that emits an invisible laser beam. The cover should not be opened when the power is turned on. This area generates high votage. Be careful not to touch here when the power is turned on to avoid getting an electric shock. 1050sa001e S-12 SAFETY AND IMPORTANT WARNING ITEMS For inch area: This product employs a Class 3B Laser Diode that emits an invisible laser beam. Be careful not to touch here when the power is turned on to avoid getting an electric shock. 1050sa050e S-13 SAFETY AND IMPORTANT WARNING ITEMS This product employs a Class 3B Laser Diode that emits an invisible laser beam. The cover should not be opened when the power is turned on. 1050sa002e S-14 SAFETY AND IMPORTANT WARNING ITEMS CAUTION The paste tank unit is very hot. To avoid getting burned DO NOT TOUCH.

1050sa005e CAUTION: You may be burned or injured if you touch any area that you are advised by any caution label to keep yourself away from. Do not remove caution labels. And also, when the caution label is peeled off or soiled and cannot be seen clearly, replace it with a new caution label. Classification Load symbol Ex.And the paper feed direction that is perpendicular to the longitudinal feed is referred to as the transverse feed. For the transverse feed, no specific notation is employed. Therefore, the descriptions given in this service manual may not coincide with the actual machine. When any change has been made to the descriptions in the service manual, a revised version will be issued with a revision mark added as required. A number within 1 represents the number of times the revision has been made. However, be sure to take note of the AC connection mode. Carbonless paper and recycled high-quality paper are only for character image.Developer 1,000,000 220h The time during which the developing roller is being driven. The relationship between the driving time mentioned above and the actual number of prints has certain conditions. Reference: Relationship between the number of prints and the drive time 220 hours drive at A4 continuous output of 11 sheets per job is equivalent to 1,000,000 prints.Actual Parts count replacement No. Actual Parts count No. Classification 3. PERIODIC CHECK Part name Part number Qt. Actual Parts count replacement No. Clean the outside and the inside of the developing suction assembly with the cleaner. It does not rotate in the reverse direction (counterclockwise). However, a one-way mechanism is provided on the inside of the collar of the paper feed roller with no mechanism provided for the separation roller. Be careful not to confuse one with the other. 1. 2. Remove the pick-up roller assembly. Be sure to conduct this operation with two people.

Holding it at positions other than those specified may cause damage to the tray, thus resulting in a paper feed jam. (1) Procedure 1. 2. Open the toner supply door. At this time, take note that the spacer does not get caught by the stepped section of the screw. When this operation is not made, insufficient fusing may result when printing a thick paper.Using this system dispenses not only with printing the list on paper but also visiting the users. The operation of the functions is available while in jams, SC and a low power mode. When the main power switch (SW1) is turned off. When the power switch (SW2) is turned off. While the copier is in auto shut-off. When the security enhanced mode is set to ON (the use of the main body NIC is not allowed.) In this manual, the network interface card installed in the main body is called the main body NIC. 4.4.3 Major functions Sending a mail with a simple keyword allows you to use the following functions. (1) The list print information of the copier you want to obtain can be received by mail. List prints that can be obtained are the following 11 lists. To make use of the above functions, it is necessary to send a mail with a simple keyword (command). For particulars, contact the system administrator. B. Setting from the Web Utilities Enter the setting of the mail server from the Web Utilities. To use the Web Utilities, make preparations of a PC that can be connected to the network. For particulars, contact the network administrator. For Web browser, Internet Explorer or Netscape Navigator is recommended.Receiving mail Set the IP address of the incoming mail server.E-mail address Enter the mail address of the copier its own. No entry cause no problem. CE password Enter a password that is added to the title (subject) of a mail sent to the copier. The copier uses this password for security purpose.

Announce delay A selection is made if the difference (time required) between the time when a time in replay mail was sent to the copier and the time when the copier handled the mail is mail indicated in the mail. Enable POP After authentication is made by the mail receiving server, a selection is made (IMAP) before to decide whether to send out the mail or not. Sending test A mail sending test is made on the SMTP server. Au ALL Send back all of the above list prints in mail. And this is sent back by mail. When there is a space or TAB found at the line head, the line is ignored. (7)The maximum number of commands available in a mail is ten. Commands exceeding ten are ignored. (8)Avoid attaching a file to a mail that is sent to the copier. (9)A signature on a mail that is sent to the copier may be handled as a command with an error message sent back. (10)When the power is shut off while the copier is sending a mail or when the copier main body is printing the list print, the same mail may be sent back twice. (11)The copier can receive up to 5 mails from the mail server at the same time. Conducting the ISW allows the version up of control program without changing the board and the installation of the up to date program when replacing the board. As a tool to conduct the ISW, (ISWTrns (PC software)) can be used for rewriting with the personal computer (PC) connected to the copier. The ISWTrns does not correspond to the data transmission through the parallel port. Accordingly, sending data in the ECP mode may result in an error while in transmission. Therefore, when using the ISWTrns with the PC set in the ECP, it is necessary to release the ECP mode. 1) ECP port release procedure The following procedure shows the release of the ECP mode. For release of the ECP mode, contact the sys- the ECP port.In the copy error file list, files the copy of which have been failed are listed.

Image processing PC Overall control board board Printer control board RADF control board FNS control board FD control board SD control board PB control board LS control board IC board When conducting the ISW in the entire system, be sure to conduct it in the order shown below. So, when the board is replaced, the ISW is not required. For FS and SD, be sure to take note of the followings. In the condition like this, when the power switch is turned on, the system gets into the ISW standby status. And when an abnormality occurs while in rewriting the image processing program and the contents of the memory is damaged, the power save LED is flashing when the power is turned on again, and the system gets into the ISW standby status. In the main screen, the selection of transferred files (rewritten data), the display of information, the confirmation of a transferred file (rewritten data) and the transmission of the transferred file (rewritten data) are conducted. The files to be displayed are described with the wild card name in the ISWTrns.INI file. Accordingly, when there are plural version files in the same file, plural versions are to be displayed in this list box. The list displayed here is sorted in the order of names, and when the list is displayed, an item displayed last is selected. The number of files actually transferred is described in the checksum file attached to the transferred file (rewritten data). For the LED display, see the table given below. No.

In the case of ftp, set the relative path from the home directory. And conduct this operation when the copier is not used. When the copier is in use (with jobs accompanied), Internet ISW does not operate. (2) When the power supply is cut off while writing the image control program in the overall control board (OACB). When the main power switch (SW1) turns off due to a power failure, the copier does not start up.

When accessing the outside through the proxy server, or when the entry of the user name and password of the proxy server is not required, this proxy authentication is likely to be used. When all the settings are made correctly and no communication is available with type 1 authentication, this setting is used. When all the settings are made correctly and no communication is available with type 3 authentication, this setting is used. For most of the proxy servers, the type 1 authentication is used. The displacement of the slit glass may cause the image read by the DF to be deformed. Therefore, the installation positions of the mirror unit and the exposure unit must not be arbitrarily adjusted. Accordingly, screws that lead up to the disassembly of the CCD unit are not allowed to be removed. The lens reference plate assembly acts as the basis for the installation position of the CCD unit. Removing this assembly may cause the displacement of the optical axis of the CCD unit. Opening the cover allows dust and dirt to get inside, which may block the laser light path. They have been adjusted to an appropriate value in advance. Accordingly, the attaching screws of the transfer guide plate are not allowed to be removed. The transfer assist home sensor (PS37) detects the starting point to drive the transfer assist sheet assembly and the displacement of this position may result in poor transfer or damage to the drum. Removing it may undermine the parallelism of the drum with the write section, thus causing the image to be deformed. Remove 2 optics unit positioning jigs. When paper sizes other than the standard sizes are used more frequently, the transfer assist sheet can be changed to these sizes. (2) Characteristics 8 types of the transfer assist sheets are provided according to the paper sizes. However, when changing to sizes other than those provided as standard equipment, it is necessary to add a new relay wiring harness and size detection connector.

However, this counter counts any relevant size regardless of the size of the transfer assist sheet installed to the main body.For coated paper while in off-set printing, ink gets dry slowly. Therefore, to prevent the transfer of ink onto the backside of the paper, powder is normally sprinkled. The cleaning brush is used to prevent the occurrence of a no feed condition due to this powder. However, to maintain the specified performance, the cleaning brush needs to be cleaned every 2,000 sheets of paper through while in overlay printing. Do not use the cleaning brush for the paper with many paper powders. The cleaning brush may be clogged by the paper powder and the conveyance power may be reduced. (2) Characteristics The cleaning brush can clean the pick-up roller and the paper feed roller. Since it is used while in the overlay printing, it can be installed only in the tray 4 of PF-701 that is used while in the overlay printing. C. Paper feed assist plate (1) Purpose The paper feed assist plate is used to adjust the pick-up pressure on paper by changing the load on the pick-up roller. Adjustments can be made according to the type of paper to increase the paper feed performance. Improve a non feed condition that is apt to occur when feeding paper, such as a thick paper, that is hard to convey. (2) Characteristics The paper feed assist plate weighs about 10g and the pick-up roller can be equipped with up to 4 plates. For CMS corresponding parts, 9 types of parts are set. DIPSW CMS Function Counter No. Also, when operating the machine to be adjusted and the method of adjustment that is with the power supplied, be careful of the scan required by this machine, it also gives detailed expla- of the exposure unit and be sure not to get nations.Be careful 3.

Items are numbered in a circle by the priority if there is any. Contact the service manager of the authorized distributor if it is considered that the PB is also damaged. The parameter board (PB) stores various adjustment data, setting data and counter data. Therefore, when replacing the PB, perform all adjustments and settings, and be sure to replace the parts for control correction (Drum, developer, cleaning blade, cleaning web).
