In this Handbook, work procedures are given in the form of tables instead of flow charts used general- ly. Familiarize yourself by studying the example below. EX. AC power is absent. ■ To find out the cause (problem part) of a single problem, refer to the item under “Cause/Fault.” For “AC power is absent,” the cause may be the power plug, covers, power source, or others. ■ To find out the checks to make or remedies to provide for a single problem, refer to the “Checks” and “Remedies”; make checks, answer to the questions YES or NO, and provide remedies accordingly. If the answer is otherwise, proceed to the next step. ■ Checks on the voltage using a meter call for special note; the description “Check the voltage between J109-1 (+) and J109-2 (–) on the DC controller PCB” means that the positive probe of the meter should be placed on J109-1 (+) and the negative probe, on J109-2 (–). Are the front door and delivery cover closed properly? Is the rated voltage present at the power outlet? Is the power plug connected to the power outlet? <Check> <Answer> <Answer> <Remedies> 1 <Step> 2 3 YES NO NO NO YES YES Connect the power plug. Close the door or the cover. The problem is not of copier. Advise the customer as such. i Guide To Tables Cause/Fault Power plug Covers Power source Step 1 2 3 4 Answer NO NO NO YES Check Is the power plug connected to the power outlet? Are the front door and delivery cover closed properly? Is the rated voltage present at the power outlet? Is the rated voltage present between J1-1 and -2 (near cord plate)?

CHAPTER 1MAINTENANCE AND INSPECTION A. Image Basic Adjustment Procedure 1–1 1 Clean the primary charging roller/transfer charging roller. • To clean the primary/transfer charging roller, execute 'roller cleaning' under adjustment/cleaning' in user mode. Clean the separation static eliminatir. Is the setting of 'EXPOSURE RECALIB''under adjustment/cleaning' in user mode a medium value? Is the setting of service mode'*3*' the value recorded in the label attached to the front door? Make two to three copies in non AE (copy density at 5). Set it a medium value. NO YES YES Enter the value recorded in the label. NO Is the white background foggy? YES Excute shading auto correction. Make two solid black copies with the copyboard cover or the feeder open Service mode (*3*) Set 'DENS-ADJ' to'5' Is the white background free of fogging? Service Mode (*3*) Set 'DENS-ADJ' to '5' or lower. Are there vertical lines (white,black)? NO YES Clean the separation static eliminator, dust-proofing glass, mirrors (No.1,No.2,No.3), standrd white plate,and lens. Are the copies free of vertical lines? NO YES NO END Service mode (*4*) Service mode (*4*) Excute the following three items: auto density correction PD 200PWM 60PWM YES NO Downloaded from www.Manualslib.com manuals search engine

A. Mechanical 1 Image Leading Edge Margin (REGIST; registration roller ON timing) Select ‘REGIST’ (4th screen) in service mode (*3*; ADJUST) and adjust so that the image leading edge margin is 2.5 ±1.5 mm in Direct. Figure 2-201 2 Left/Right Registration (front) a. Pick-Up from the Cassette Check to make sure that the margin on the front side is 2.5 ±1.5 mm when paper is picked up from each cassette. Figure 2-202 Otherwise, perform the following: 1) Slide out the cassette to be adjusted. 2) Remove the two screws q, and remove the horizontal registration adjustment assembly. Figure 2-203 3) Loosen the hex screw, and slide the horizontal registration plate toward the rear to adjust. Figure 2-204 (rear) (front) Horizontal registration plate Hex screw Hex screw diameter 4mm 1 Horizontal registration adjustment assembly (–) (+) 2.5±1.5mm 0 2 4 6 8 10 2.5±1.5mm 2–1 STANDARDS AND ADJUSTMENTS CHAPTER 2 STANDARDS AND ADJUSTMENTS 2 Downloaded from www.Manualslib.com manuals search engine

Caution: To adjust, try so that the L-shaped notch on the inside of the horizontal plate and the appropriate scale notch match. Figure 2-205 b. Pick-Up from the Multifeeder Loosen the screw and move the tray position so that it is 2.5 ±1.5 mm in Direct. 3 Left/Right Registration (rear/front) on the 2nd Side of Two-Sided/Overlay Copies Check to make sure that the printing position of the image on the second side of a two- sided/overlay copy is 2.5 ±2.0 mm. Figure 2-206 If the value is not as specified, select ‘RSID- SENSHP’ (4th screen) in service mode (*3*; ADJUST), and make adjustments. • An increase by ‘23’ of ‘RSID-SENSHP’ will shift the image print position to the rear by 1 mm. A decrease by ‘23’, on the other hand, will shift the position to the front by 1 mm. 2.5mm±2.0 Decrease the value of 'RSID-SENSHP'. (A decrease by 23 causes a change of 1 mm.) Increase the value of 'RSID-SENSHP'. (An increase by 23 causes a change of 1 mm.) 2–2 STANDARDS AND ADJUSTMENTS Downloaded from www.Manualslib.com manuals search engine
