GENERAL PRECAUTIONS REGARDING THE INSTALLATION AND SERVICE FOR e-STUDIO160/200/250 SERIES The installation and service should be done by a qualified service technician. 1. Transportation • When transporting/installing the copier, employ two persons and be sure to use the positions as indicated below. The copier is fairly heavy and weighs approximately 50 kg (110 lb), therefore pay full attention when handling it. 4 portions 2.
• Avoid exposure to laser radiation during servicing. – Avoid direct exposure to beam. – Do not insert tools, parts, etc. that are reflective into the path of the laser beam. – Remove all watches, rings, bracelets, etc. that are reflective. 4. Main Service Parts for Safety • The breaker, door switch, fuse, thermostat, thermofuse, thermistor, etc. are particularly important for safety. Be sure to handle/install them properly. 5.

3. PRECAUTIONS FOR STORING & HANDLING SUPPLIES 3.1 Precautions for Storing TOSHIBA Supplies A. Toner cartridge Toner cartridge and process unit should be stored in a shaded place where the ambient temperature is between 10 to 35°C (no condensation), and should also be protected against direct sunlight during transportation. B.
3.2 Checking and Cleaning of the Pressure Roller (1) Handling precautions Do not allow any hard object to hit or rub against the surface. Do not stain the pressure roller surface with any oil of fingerprints, etc. Do not allow solvents such as paint thinner to touch the pressure roller surface. (2) Cleaning procedure Use a cloth which should be soaked in water and then wrung strongly to clean the pressure roller surface. 3.
3.4 Checking and Cleaning of the Heat Roller (1) Handling Precautions Do not leave any oil (fingerprints, etc.) on the heat roller. Be careful not to allow any hard object to hit or rub against the heat roller, or they may be damaged, possibly resulting in defective cleaning. (2) Checking Check for stain and damage on the heat roller and clean if necessary. Clean the separation claws and check for chipped claw tips. Check the cleaning effect of the cleaning roller.
3.6 Checking and Cleaning of the Photoconductive Drum (1) Use of gloves Since fingerprints or oil stains on the drum surface affects the quality of the copy image and degrades the characteristics of the photoconductor, do not touch the drum surface with your bare hands. (2) Handling precautions As the drum surface is very sensitive, be sure to handle the drum carefully when installing or removing it so as not to damage its surface.
3.7 Checking and Cleaning of the Drum Cleaning Blade (1) Handling Precautions Since the edge of the cleaning blade performs the cleaning operation, pay attention to the followings: • Do not hit or rub the blade edge with anything hard. • Do not rub the edge with a dry cloth or soft pad. • Do not stain the edge with oil or fingerprints, etc. • Do not put solvents such as paint thinner or the blade. • Do not leave lint or dirt on the blade edge. • Do not put the blade close to a heat source.
4. TROUBLESHOOTING Before starting any repair work, strictly obey the following instructions. CAUTION: • When replacing parts, be sure to turn the main switch OFF and unplug the power-cord plug from the outlet. Notes: • Be sure to output a dial list and a system function list and keep them until the troubleshooting is completed so that if the user’s set data is lost it can be re-entered.

5. UPDATING THE FIRMWARE 5.1 Outline When you want to use the latest version of the firmware, or when the firmware is damaged and the copier is inoperable, the following procedure is used to update the firmware. The firmware contains two types of data: Main Data (program data/function data/language data) stored in the flash ROM on the main PWA, and Scanner Data stored in the flash ROM on the scanner control PWA. The updating procedures vary with the data types. For details, refer to each procedure.
5.2 Using the Recovery PWA Downloading procedures differ with the main data and the scanner data. Refer to the following sections: • Main data: 5.2.1 Using the main recovery PWA (this page) • Scanner data: 5.2.2 Using the scanner recovery PWA (on page 5-5) 5.2.1 Using main recovery PWA Important: While downloading, do not turn off the power of the copier. Data may be damaged, causing the copier not to operate normally. (1) On the main recovery PWA, install the ROM that stores data for the update.
(4) Insert the main recovery PWA into CN10 of the main PWA, with the ROM mounting side facing down. Main PWA Main recovery PWA CN10 05-02-03 Fig 5-2-3 (5) Turn on the power. Downloading of the main data starts. The downloading status is displayed on the LCD of the copier as follows: • Data is being downloaded from the ROM on the recovery PWA to the DRAM on the main PWA. The number of displayed squares () increases.
(6) Turn off the power. (7) Remove the main recovery PWA and attach the rear cover. Important: Only when the main data is downloaded after changing the main PWA. In such a case, follows the step (a) through (g) described below. (a) Holding down the [0] and [8] keys, turn on the power. The copier enters the System mode. (b) Enter “388” using the numeric keys and press the [SET]/[START] key. The total counter value is baked up. (c) Turn off the power.
5.2.2 Using the scanner recovery PWA Important: Do not turn off the power of the copier while downloading. Data may be damaged, causing the copier not to operate normally. (1) On the scanner recovery PWA, install the ROM that stores data for the update. Closely follow the ROM installation direction. Connector Scanner recovery PWA ROM 05-02-04 Fig 5-2-4 (2) Turn off the power. (3) Open the Original cover (KA-1600PC)/ADF (MR-2012)/RADF (MR-3011). (4) Removes the original glass and the original glass stay.
(5) Remove the blind plate. Blind plate 05-02-06-1 Fig 5-2-6 (6) Insert the main recovery PWA into CN3 of the scanner control PWA, with the ROM mounting side facing outside the copier.
(7) Turn on the power. Downloading of the scanner data starts. The exposure lamp flashes as follows depending on the downloading status. • The exposure lamp flashes once: Downloading starts. • The exposure lamp flashes twice: Downloading ends. Note: It takes approx. 10 to 20 seconds to download the scanner data. (8) Turn off the power. (9) Remove the scanner recovery PWA. (10) Attach the blind plate. (11) Attaches the original glass and the original glass stay.
5.3 Using the Batch File You can execute the download program from the batch file on MS-DOS and download the firmware into the copier from the PC for update. This method consists of the following two procedures: “Download Disk Creation” and “Download Run Operation.” Once download disks are created, you can update the firmware in more than one copier or other machines to the one of the same latest version simply by performing the download operation using the created download disks.
The MS-DOS prompt screen shows the following: 05-03-001 (1) Type “mkrpcdsk” and press the [Enter] key. 05-03-002 The batch file is executed and the download disk creation program is started. 05-03-003 (2) Insert a blank floppy disk (Disk 1) in the drive and press the [Enter] key. 05-03-004 (3) Press the [Enter] key. Formatting of Disk 1 begins.
