ADJUSTMENT HOW TO USE THIS SECTION This section details adjusting items and procedures. Use this section for making adjustments and as a checklist before implementing corrective measures in the field. 1. Does the power supply meet the requirements? 2. Is the power supply properly grounded? 3. Is the machine sharing its power source with another high current consumption machine that draws large currents intermittently? (for example, an elevator, air conditioner, or other source of electrical consumption) 4. Is the installation environment suitable? a. Keep out of High humidity, direct sunlight, bad ventilation, etc.. b. Make sure that the floor where the machine is installed is level. 5. Does the cause of a defective image lie in the original itself? 6. Is the density adjusting control at the proper position? 7. Are the original glass and original cover clean? 8. Is the correct paper being used for the copy? 9. Are the copying materials and parts replaced when they reach the end of their usable life? (developer, drum, cleaning blade, etc.) 10. Is there toner in the machine? The following items should also be observed when repairing the machine. 1. Both AC power lines are disconnected when the main switch of this machine is turned off. However, the optional PTC heater remains ON and keeps high temperature since the interlock switch is turned ON. So, always unplug the machine before beginning work. If absolutely necessary to work with the power on, exercise care not to get caught in gears or scanning operation of exposure unit. 2. Take special care when handling the fixing unit since it operates at extremely high temperatures. 3. The developing unit is surrounded by a strong magnetic field. Keep watches and metering equipment away from it. 4. Avoid scarring the drum with tools or similar objects. 5. Do not touch IC pins with your bare hands. ADJUSTMENTS WHEN REPLACING PARTS Adjustments (including checks) and settings are required not only when a defective copy image occurs, but also after replacing or reinstalling certain parts. [How to Use the Table] The following items in the table are used. 1. Mode Indicates the adjustment mode. ["47"] : 47 mode ["25"] : 25 mode ["36"] : 36 mode [ -- ] : Normal mode 2. Code Indicates the applicable code. 3. VR Caution: All VRs on the boards are for factory adjustment. Do not adjust them. · [--] None · Indicates the VR number on the CB (Control Board). · Indicates the board name when VR is mounted on a board other than the CB. 4. Page Indicates the page to refer to in the adjustment or diagnostics sections. 5. Conditions New : Indicates adjustment (including check) is required when replacing a new part. Re-set : Indicates adjustment (including check) is required when a part has been reinstalled. 6. Circled numbers used in the table 1 , 2 ... : Indicates there is a priority sequence for adjustments (including check) and settings. : Indicates adjustments (including checks) and settings which can be carried

DIAGNOSTICS 25 MODE [1] Setting procedures A special operating mode called the 25 Mode has been provided exclusively for specifying various settings. This mode allows data in memory IC to be rewritten. (1) Turn the main switch OFF. (2) While pressing the numerical keys 2 and 5 of the copy quantity setting button, turn the main switch ON. This will enable the 25 Mode. The 25 Mode is used exclusively to rewrite in memory and, therefore, does not support normal copy operations. (3) Using the copy quantity setting buttons, specify the address number of the data to be changed. (a) Press the P button. The address number will blink in the magnification indicator. (b) Enter the desired address number using the copy quantity setting buttons. The newly-entered address number will blink in the magnification indicator. (c) Press the P button. The blinking address number will be lit. (4) Rewrite the data currently stored in that address. (a) Enter the new data using the copy quantity setting buttons. The old data appears in the tens digit position of the copy quantity indicator and newly-entered data in the ones digit position. (b) Press the copy button. This will rewrite the data and change the copy quantity display to show the new data in the tens digit position. (5) Turn the main switch OFF to exit the 25 Mode. 6-1 DIAGNOSTICS [2] 25 Mode Address Map Address 00 01 02 03 04 05 06 07 08 09 10 11 12 13 Copy quantity setting limit selection 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 105 104 10 10 3 Item Setting range Initial value Change details Remarks Auto Low power mode setting time selection 0, 1 0 0: setting time 1 : setting time+120min *1 Auto shut off mode setting time selection 0, 1 0 0: setting time 1 : setting time+120min *2 Auto start original selection Counter selection (P+1) 0-2 0, 1 0 0 0: Total count 1: Copy (developing) count *3 0-9 0 0: Max. 1: 1 2: 3 3: 5 4: 9 5: 10 6: 20 8: 50 9: 99 7: 30 A size mode selection Preferential paper size selection OHP interleave selection Auto Low power mode time setting 0, 1 0-5:USA 0, 1 1-5 0 2:USA 1 4 0: Normal 1: A size priority *4 0: Copy sheet 1: Blank sheet 1: 2 min. 2: 5 min. 3: 10 min. 4: 15 min. 5: 30 min. 0-8:Europe 1:Europe Auto start release time 0-3 1 0: 10 sec. 1: 20 sec. 2: 30 sec. 3: Not released Copy control protection area 1 ADF frame erase selection 104 10 3 0, 2 0, 5 0-9 0 5:USA 0: Protected 2: Not protected 0:Europe 0: None 5: 5mm frame 3 0 PM cycle specification 0 PM count 0-9 0 2 9 9 9 9 102 1 100 6-2 DIAGNOSTICS Address 38 39 40 41 42 43 44 45 46 105 104 10 3 Item Drum count Setting range Initial value 0-9 0 0 0 0 0 0 0,1:Europe 0-2:USA 0-3 0 0 Change details Remarks 102 101 10 0 Minimum original size detection selection Sorter initial mode setting *5 0 : Non-sorter mode priority 1 : Sort priority 2 : Group priority 3 : Sort/Staple priority 47 48 Clearing fixing failures Auto reset setting 0-9 0-1 0 1

SERVICE Primary Precautions to be Observed During Maintenance 1. Before troubleshooting a particular problem, consult the operator to obtain clues that may assist in finding the problem. Who would be more familiar with the symptom of the problem than the individual that constantly operates the machine. 2. Copy Samples Always make copy samples before and after your maintenance service to ensure proper machine operation. 3. Drum · Do not expose the drum to sunlight or room light. When the drum is removed from the machine, place a cover over it. · When cleaning the photosensitive surface, use a cleaning pad moistened with the specified drum cleaner. Never use solvents other than the drum cleaner; otherwise the photosensitive material of the drum can be dissolved. 4. After maintenance is completed, remember to reset the PM counter. (47 mode, Code 90/See the adjustment section for details.) 5. Always reset the drum counter when replacing the drum. (47 mode, Code 91/See the adjustment section for details.) Caution Be sure to turn the main switch OFF and pull the plug before working on the machine. 7-1 SERVICE SERVICE SCHEDULE [1] Service Schedule Copy Q'ty Model Service items (Unit:1,000cps) 0 30 60 90 120 150 180 210 240 270 300 330 360 390 Guarantee period (5years or 400,000cps) Number of cycle Maintenance (Every 30,000cps) Main body Periodic check ( I ) (Every 60,000cps) Periodic check ( II ) (Every 120,000cps) ADF DF-204 Maintenance (Every 30,000cps) Periodic check ( I ) (Every 210,000cps) DBU DB-607 Maintenance (Every 30,000cps) DB-207A Maintenance (Every 30,000cps) STR ST-103 Maintenance (Every 30,000cps) ST-104 Maintenance (Every 30,000cps) Periodic check ( I ) (Every 60,000cps) Periodic check ( II ) (Every 90,000cps) 13 6 3 13 1 13 13 13 13 6 4 7-2 SERVICE [2] Maintenance Items 1.
