Wait for the machine to shut down, and then disconnect the machine from the power supply.
Page 6 Self-Diagnostic Mode Self-Diagnostic Mode at Power On As soon as the main machine is powered on, the controller waits for the initial settings of the copy engine to take effect and then starts an independent self-diagnostic test program. The self-diagnostic test follows the path of the flow chart shown below and checks the CPU, memory, HDD, and so on.
Page 7 Detailed Self-Diagnostic Mode In addition to the self-diagnostic test initiated every time the main machine is powered on, you can set the machine in a more detailed diagnostic mode manually in order to test other components or conditions that are not tested during self-diagnosis after power on. Executing Detailed Self-Diagnosis Follow this procedure to execute detailed self-diagnosis.

Page 638 2.Image Quality Problems If the problem cannot be resolved, consult the product specialist. Streaks (1) Streaks parallel to the paper feed direction appear. Cause: The charger is dirty.  The PCDU cleaning unit is worn out.   The drum surface is scratched. Solution: On the TCRU menu, execute [Clean Charge Unit].
Page 639 2.Image Quality Problems Streaks (2) Extended, blurred streaks parallel to the paper feed direction appear. The streaks also appear randomly in the margins. Cause: If the temperature or humidity is low, the cleaning blade of the ITB cleaning unit or transfer unit may miss the remaining toner, causing streaks to appear sporadically.
Page 640 2.Image Quality Problems Solution: Print 350 full-page, solid-fill A3 or DLT sheets. Check the image. Is the problem resolved? Finished Replace the toner bottle.

Page 642 2.Image Quality Problems Cause: The invert exit drive rollers or invert exit idle rollers in the drawer are dirty. This may occur when sheets are delivered face down after one-sided printing. Solution: Clean the rollers, sensors, and guide boards in the drawer. Make sure that power is turned to OFF, and the machine power cord is disconnected from the power source.
Page 643 2.Image Quality Problems Clean the rollers, sensors, and guide boards. (Cleaning the Paper Feed Path) After cleaning, restore the machine so that it resumes operation. Two 14-mm Wide Streaks Two 14-mm wide streaks parallel to the paper feed direction appear. Cause: The exit drive rollers, exit idle rollers, exit relay drive rollers, or exit relay idle rollers in the drawer are dirty.
Page 644 2.Image Quality Problems Lower the levers C1 and C2, and then pull the drawer out completely until it stops. Pull up and open the cover D3. Clean the rollers while turning the knob D1. Clean the sensors and guide boards. (Cleaning the Paper Feed Path)
Page 645 2.Image Quality Problems Stained Background Random "powdered" dots appear, creating a dirty background. The background may be partially or completely stained. Completely stained background Partially stained background Cause: This may occur due to deterioration of developer, the drum unit, or the drum charge unit. Solution: If a message prompting replacement of a unit is displayed, replace the unit.
Page 646 2.Image Quality Problems Ghosting A ghost of the image appears at a distance of 314 mm (12.4 in.) to the side of the image. Cause: The image transfer current is transmitted to the drum, where a potential difference occurs between a developed area and non-developed area and causes the image to be reproduced.
Page 647 2.Image Quality Problems Cause: When transporting thick paper that is very stiff, the stiffness of the paper causes the entrance guide board for the transfer unit to warped toward the ITB. The edge of the entrance guide board comes into contact with the toner on the belt, thus causing the images to be scratched and the paper edges to be soiled.
Page 648 2.Image Quality Problems cloth. If this does not solve the problem, replace the paper transfer roller.
Page 649 2.Image Quality Problems Toner Scatter Toner Scatter 1 (Around Edge of Solid Fill) Toner is scattered around a solid-fill print.

Page 664 2.Image Quality Problems charge from the transfer electrical field, thus reducing the efficiency of image transfer. This may also occur when: Ambient temperature and humidity are low   Paper is extremely thick Electrical resistance of paper is high  Duplex printing (problem occurs on Side 2).
Page 665 2.Image Quality Problems Rough Images Appear During Low Duty Use During low duty use of the machine, air can become mixed with the developer/toner mixture during agitation and cause rough patches to appear. Cause: When the machine is consistently used for low duty printing, air can mix with the developer/toner mixture during agitation which can cause developer deterioration and cause rough patches to appear on images.
Page 666 2.Image Quality Problems Periodic changes in the speed of paper feed can cause the images to stretch, leading to unevenness in image texture in the shape of black vertical lines. This can also occur when: Ambient humidity is high  ...
Page 667 2.Image Quality Problems Cause: Ambient conditions and paper characteristics (such as slick surface or electrical resistance) may cause too much charge in the electrical field, making dots appear. This can occur when:  High temperature, low humidity Coated paper is used ...
Page 668 2.Image Quality Problems Repeat from Step 2. If the problem persists, consult the product specialist. Adjustment of the image transfer current can cause white spots on the images. Adjust  carefully. If white spots appear, select the best result from the samples, and apply the settings used for that test print.
Page 669 2.Image Quality Problems Firefly, Comet Patterns White spots in firefly patterns, or black comet streaking patterns appear. Cause: White firefly patterns with white spots in the center are caused by toner clumps. If these clumps break down in the development unit, black streaks in the shape of comets may appear. This can occur when: ...
Page 670 2.Image Quality Problems White Parallel Stripes White stripes on the images caused by toner additives adhering and accumulating on the surface of the drum. Cause: After continuous high quality printing, there may not be sufficient lubricant on the surface of the drum. As a result, toner additives adhere and accumulate on the drum surface, causing parallel white streaks at intervals of about 314 mm (12.5”).
Page 671 2.Image Quality Problems Toner Splatter on Edge Toner falls from the image transfer belt onto the edge of the print. Cause: Toner falls from the ITB cleaning unit onto the paper near the edge. Normally, this does not happen; however, if parts of the cleaning unit such as the cleaning blade is damaged, toner falls from there onto the paper.
Page 672 2.Image Quality Problems When paper with a lot of paper dust enters the nip of the PTR unit, the paper dust adheres to the entrance guide plate of the PTR unit. From the guide plate, this paper dust is then transferred to the paper, causing the white spots.
Page 673 2.Image Quality Problems image is abnormal. Also, when using paper weighing 300 g/m2 or heavier, the trailing edge of paper may come in contact with the image transfer belt, resulting in scratched images .
Page 674 2.Image Quality Problems Density Problems Uneven Image Density The density is uneven. Solution: Depending on the type of unevenness, the solution is different. Refer to the table below. (A) The density is uneven across the entire image. The density from top to bottom is uneven.

Page 787 4.Troubleshooting for Peripheral Units Print the image. Is the problem resolved? Finished. Consult the product specialist.  For details about attaching the Z-fold support tray for multi-folding unit, see the user manuals that come with the machine.  If the Z-fold support tray for multi-folding unit is attached, the trailing edge of the ejected sheets will not be too close to the paper exit, so no problem will occur.
Page 788 4.Troubleshooting for Peripheral Units If the paper is curled face up, select "U Curl". If the paper is curled face down, select "П Curl". Depending on how much the paper is curled, specify the degree of correction by selecting "Small" or "Large".
Page 789 4.Troubleshooting for Peripheral Units If the delivered sheets continue to be curled, use the decurl unit to correct the curl to the opposite side. * If this is not possible, switch the settings for ejected sheets between face up and face down. Pointed Flap Envelopes Not Stacked in Correct Order Envelopes with pointed (triangular) flaps are not delivered in the correct order, or fall from the exit tray.
Page 790 4.Troubleshooting for Peripheral Units  [A]: End Fence Factor 3: Height/inclination angle of the paper stack increases because of the uneven paper thickness The thickness of the flap (the part detected by the finisher) is thinner than the other parts of the envelope.
Page 791 4.Troubleshooting for Peripheral Units When attaching the Z-fold support tray, ask the customer to accept the following:   Alignment accuracy is not assured. The maximum stack capacity for the finisher shift tray is 30 sheets. Remove output sheets  from the tray every 30 sheets.
Page 792 4.Troubleshooting for Peripheral Units Attaching the Z-fold support tray reduces the angle of the finisher tray, so the distance between the tray and the leading edge of delivered paper increases. As a result, it takes time for the trailing edge of delivered paper to fall.
Page 793 4.Troubleshooting for Peripheral Units Thin Paper (64 gsm or Below) Not Stapled, Dog-Eared, Not Stapled Correctly, or Not Stacked Properly Reduce the amount of curl by loading the paper the other side up.

Page 798 4.Troubleshooting for Peripheral Units If this happens, stapled sheets, when they are delivered, may push the previous delivered sheet, resulting in paper bending or jam. This is likely to occur if:  There is a tight curl on a delivered set of stapled sheets. Limp paper such as thin or recycled paper is used.
Page 799 4.Troubleshooting for Peripheral Units Deliver some A3/DLT or A4 LEF paper onto the proof tray. Check how much the edge of the paper has shifted from the center scale. If the paper shifted towards the front  Slide the docking bracket towards the front side by the amount of shift, in order to move the finisher in the same direction.
Page 800 4.Troubleshooting for Peripheral Units in the same direction. For example, when the paper has shifted by 4 mm towards the rear from the center mark (2 mm/division of the scale), move the docking bracket towards the rear by 4 mm (2 divisions). The divisions move towards the front.
Page 801 4.Troubleshooting for Peripheral Units Cause The paper slackens due to the difference in level between the trailing edge fence and stapling stacking fence, causing misalignment. Solution Adjust the position of the trailing edge fence using the SP mode. The factory-set value is on the sticker at the position indicated by the red frame. Check the label indicating the initial value.
Page 802 4.Troubleshooting for Peripheral Units By adjusting the SP value in the positive direction, the staple stacking fence is moved up and toward the trailing edge fence. By adjusting the value in the negative direction, the staple stacking fence is moved down and away from the trailing edge fence.
Page 803 4.Troubleshooting for Peripheral Units Streaks Appear 4 mm Apart on the Leading Edge of the Stacked Paper Cause: During back-curl correction, the paper is compressed by the nip of the sponge roller [A] above and the decurl roller [B] below, so the sponger roller can press down to correct the paper curl. If the image on the paper [C] is facing up when the sponge roller presses down, this can cause toner from the image to peel off and dirty the anti-static brush, which then transfers this toner to the leading edge of each sheet.
Page 804 4.Troubleshooting for Peripheral Units number of pre-stack sheets must be reduced, causing lower productivity. Be sure to consult the product specialist before removing the anti-static brush.
Page 805 4.Troubleshooting for Peripheral Units Multi-Folding Unit Poor Folding Cause: Depending on paper hardness, inaccurate folds may result. This is referred to as folding deviation. Solution: Change the folding position by adjusting the position of the paper edge stopper for folding.

How to adjust the folding deviation This procedure is the same for L1, L2, and L3. Open the front cover of the multi-folding unit. Remove the mounting screw.
Page 810 4.Troubleshooting for Peripheral Units Folds Dirty by Multi-Sheet Folding Cause: If multi-sheet folding is performed after a large number of Z-folds have been performed, the tip of the blade used for the multi-sheet folding may be dirty, resulting in dirt on the paper. This will produce dirt on the paper in an area of 1-3 cm (0.4-1.2 inches) in width (equal to the width of the blade) in the fold in the center of paper.
Page 811 4.Troubleshooting for Peripheral Units Wipe the tip and top of the blade with a soft dry cloth. Be careful not to damage the blade.  After cleaning, restore the machine so that it resumes operation. Apply multi-sheet folding and print 3-5 copies. The dirt on the paper will disappear. Edges of Letter Fold Bent When letter folding is applied, the edge of the inner flap may become bent.

Page 833 4.Troubleshooting for Peripheral Units High Capacity Stacker Delivered Sheets Are Severely Curled Cause: Curled sheets can cause strong friction at their leading edges. This may result in paper misfeeds. Sheets will not be ejected completely and the trailing edges will be left inside the paper exit. If this happens, other sheets may slip under the delivered sheets, causing the delivered sheets to be curled.
