  1. TROUBLESHOOTING FOR FINISHING OPTIONS

     
     

     1. FINISHER REGISTRATION ADJUSTMENT FOR BOOKLET FINISHER SR3220 (D3B9)

        Side-to-side registration can be adjusted by the docking bracket for SR3220 [A] (and the docking bracket screw [B]).

        

        1. Eject a sheet of A4(LEF) or A3 paper to the proof tray and check for how many divisions of the scale the edge of the paper has shifted from the center.

           

           [A]: Scale marks for DLT [B]: Scale marks for A3

           [C]: 7 scale marks in 2mm intervals [D]: Center mark

        2. Change the position of the standard bracket by rotating it 180 degrees as shown below.

           Troubleshooting

           This makes the docking bracket easier to slide horizontally. Then reattach the docking bracket to the mainframe.

           

           [A]: Reverse

           If the paper shifts towards the front

           Slide the docking bracket towards the front side by the amount of shift, to move the finisher in the same direction.

           e.g.: When the paper has shifted by 2 mm towards the front from the center mark (2 mm/division of the scale), move the docking bracket towards the front by 2 mm (2 divisions). The divisions move towards the rear.

           

           [A]: Proof Tray

           [B]: Docking Bracket Screw

           If the paper shifts towards the rear

           Slide the docking bracket towards the rear by the amount of shift, to move the finisher in the same direction.

           e.g.: When the paper has shifted by 2 mm towards the rear from the center mark (2 mm/division of the scale), move the docking bracket towards the rear by 2 mm (2 divisions). The divisions move towards the front.

           

           
           

           [A]: Proof Tray

           [B]: Docking Bracket Screw

           
           

           • After the adjustment, check the side-to-side registration by feeding paper out to the proof tray. If the shift has not been solved, adjust the docking bracket (screw for the docking bracket) slightly again.

     2. FINISHER JOGGER PROBLEM (FOR BOOKLET FINISHER SR3220 (D3B9)

        If a paper alignment problem occurs as shown below, do the following procedure to adjust the jogger width.

        

        Cause

        Depending on the type of paper or the manufacturer, the paper may not be the correct size. In this case, the paper may not align properly even when the jogger is used.

        Solution

        Adjust the jogger width with SP6-143 (adjustable threshold: -1.5 to +1.5 mm for each paper size).

        • SP6-143 (Jogger Pos Adj:1K FIN)

          
          

          • Adjust the jogger width to be slightly narrower (approximately -0.5 mm) than the paper width.

            Troubleshooting

     3. EARLY TRAY FULL DETECTION MYLAR FOR INTERNAL FINISHER SR3130 (D690)

        Paper curl may occur when output gets to near full. Paste the Mylar to the full detection feeler to detect tray full early before paper curl occurs.

        
        

        Pasting the Mylar

        1. Pull the finisher [A]

        6. Paste the Mylar [A] on the full detection feeler [B].

           

           
           

           Troubleshooting

        7. Re-attach the paper exit tray x2)

        8. Move the movable tray [A] up and down to check that the Mylar does go through the sensor properly.

           

        9. Re-attach the left lower cover x2)

        10. Re-attach the finisher front cover x2)

        
        

     4. PAPER CURL PROBLEM FOR SR3180 (D766)

        When using the mixed mode, duplex (curls towards the lower side) over the simplex (curl towards the upper side) and paper curl occurs, attach the auxiliary tray (D7667010), disable the paper exit full sensor, and paste the Mylar.

        1. Remove the paper exit cover [A] ×2)

           
           

           

        2. Release the clamp and disconnect the harness of the paper exit full sensor 1 [A].

        4. Release the clamp and disconnect the harness of the paper exit full sensor 2 (Staple) [A].

           

           Troubleshooting

        5. Loop and clamp the harness [A] as shown.

           • If the harness cable [A] is short to loop, clamp the harness without looping.

             
             

        6. Re-attach the paper exit cover ( ×2)

        7. Attach the auxiliary tray (D7667010) [B] to the paper exit tray [A]

           
           

           

        8. Paste the Mylars [A] on the frame of the finisher.

        

        
        

     5. MAXIMUM NUMBER OF SHEETS FOR STAPLING AND WHAT HAPPENS WHEN THE JOB HAS TOO MANY PAGES

  
  

  Specifications: Maximum sheet capability for staple jobs

  
  

  Model	Corner Staple	Booklet Staple
  Booklet Finisher SR3220	50 sheets	15 sheets
  Internal Finisher SR3130	50 sheets	-

  
  

  Behavior: When the number of sheets exceeds the maximum staple capability

  When corner stapling

  Sheets are fed out without being stapled. First, the maximum number of sheets (50) is stacked in the staple tray and fed out. Following this, any remaining sheets that exceed this maximum are also stacked and fed out without being stapled, in the same way.

  Example:

  If 60 sheets are set to be stapled, the first 50 are stacked in the staple tray and then fed out without being stapled. The remaining 10 are then stacked in the tray and fed out without being stapled.

  When the maximum number of originals for a stapled set has been scanned, "Stapling capacity exceeded" is displayed on the LCD.

  

  
  

  Troubleshooting

  There is no message displayed prompting the user to cancel or continue with the 51st original.

  When booklet stapling

  

  The following dialog is displayed when the maximum number of sheets in a stapled set is reached during the scanning of the originals. The user is prompted before printing begins.

  
  

  [Stop] The job is canceled (no further scanning, no printing)

  [Continue] Sets are stapled at maximum capacity in batch and fed out. Example:

  The machine stops scanning after 20 out of 30 originals are scanned. The message shown above is displayed.

  If [Continue] is selected, printing starts and sheets are stapled in batches of 20 sheets and 10 sheets.

  
  

  Select the behavior when the job has more than the maximum of staple capability with SP5199

  SP5-199 sets whether to staple sheets stacked in the staple tray or finisher before feeding out. 0 (default): Behavior depends on the finisher attached.

  1: Sheets are fed out without being stapled. 2: Sheets are stapled and fed out.

  6.18 VERTICAL STREAKS ON COPIES DUE TO SCANNING PROBLEMS

  6.18.1 OVERVIEW

  

  Marks on prints and copies are mostly due to dirt on the DF exposure glass [A], generally caused by adhesive contaminants (such as ball point pen ink and correction fluid).

  
  

  Compared to non-adhesive contaminants (such as paper fragments and eraser dust), adhesive contaminants are more likely to lead to complaints from customers because of the following:

• Vertical streaks caused by adhesive contaminants are more visible in terms of image quality.

• Unless removed by cleaning, adhesive contaminants continue to produce vertical streaks, while non-adhesive contaminants stop producing streaks after they are dislodged.

• Many adhesive contaminants are difficult to remove by cleaning.

The ARDF DF3090 / SPDF DF3100 features a system (non-contact scanning) to reduce vertical streaks caused by adhesive contaminants.

The ARDF DF3090 / SPDF DF3100 can be converted from non-contact scanning to contact

scanning for users who wish to reduce vertical streaks caused by non-adhesive contaminants.

Converting the ARDF DF3090 to Contact Scanning

1. Unplug the machine power cord before starting the following procedure.

2. Remove the ARDF front cover [A] ( x1).

   
   

   

3. Remove the Scanning guide plate [B] [A]x1).

   
   

   

4. Remove the plastic guides [A] on the sides of the scanning guide x1).

   

   Troubleshooting

5. Attach the guides for contact scanning. Each guide has a hole [B].

   

6. Mount the scanning guide plate, taking care not to damage the sheet [A].

   
   

   

7. Peel off the gap sheet [A] from the DF exposure glass with your hands.

   

8. Clean the DF exposure glass [A] with alcohol.

   To avoid paper jams, make sure adhesive is completely removed.

   

9. Turn the main switch on.

10. Start the SP mode.

11. Select SP4-688-001 (DF Density Adjustment ARDF) and change the setting from "106" to "103" for the contact scanning.

12. Change the DF magnification (SP4-871-003) from [0.11%] to [0.00%].

    
    

    • When returning the setting back to non-contact scanning, return the SP values also.

Converting the SPDF3100 to Contact Scanning

1. Open the SPDF and exchange the entrance lower guide unit [A] to a non-contact type part.

   
   

   

   • Entrance lower guide unit for non-contact transport: The following areas are black [A].

   • Entrance lower guide unit for contact transport: The following areas are clear and colorless [B].

     

     Troubleshooting

2. Exchange the scanning guide plate [A] to a non-contact type part (hook x 1).

   
   

   

   
   

   • [A] : The color of the marker of the non-contact type scanning guide plate for this machine is gray.

   • [B]: The color of the marker of the contact type scanning guide plate for this machine is white.

   • [C]: The color of the marker of the non-contact type scanning guide plate for previous machine is black.

     

3. Attach the scanning guide plate for contact transport [A] (hook x 1).

4. Attach the entrance lower guide unit for contact transport [B] x 2).

   

5. Peel off the gap sheet [A] from the DF exposure glass with your hands.

   

6. Clean the DF exposure glass [A] with alcohol.

   To avoid paper jams, make sure adhesive is completely removed.

   
   

   

7. Enter the SP mode.

8. Change SP4-688-002 (Scan Image Density Adjustment 1-pass) from "101" to "96".

9. Change the DF magnification (SP4-871-003) from [0.11%] to [0.00%].

   
   

   • When returning the setting back to non-contact scanning, return the SP values also.

Troubleshooting

1. IMAGE QUALITY PROBLEMS

   
   

   1. MISJUDGMENT FOR AUTO COLOR SELECTION (COPY/SCANNER)

      In the Auto Color Selection (hereafter called ACS) mode, if copying or scanning an original on which color is printed only on the edge, the original will be misjudged as monochrome. If so, color is not printed on the output.

      
      

      Error Condition

      Copy Application

      The misjudgment occurs when copying an original which has color at the edge, and that color is printed on the output 10 mm from the edge in the ACS mode.

      When using the copy application, if the original is judged as monochrome, color on the document may not be printed on the output. When printing the standard 10 colors used in Microsoft Office Word 2013 (an example is shown below), the following colors with the "x" mark will disappear if the document is judged as monochrome in the ACS mode.

      • Colors with the "x" mark will not be printed if the document is judged as monochrome. The result may differ depending on the equipment status or environment.

        

        Scanner Application

        The misjudgment occurs when scanning an original which has color only 15 mm from the edge (using the original as a standard) in the ACS mode.

        
        

        Causes

        In the ACS mode, the edge of the original is excluded from the judgment. Only the center part of the original document is the target area to judge color or monochrome (in order to prevent misjudgment due to noise).

        When copying in the ACS mode, ACS judgment and the image processing equivalent to full color is performed simultaneously. If judged as monochrome in the ACS judgment, color without a K component will not be printed.

        Solutions

        Change the ACS area excluded from judgment with the following SP settings.

        The smaller the value, the smaller the ACS area excluded from judgment becomes, which enables the document to be judged as color.

        
        

        SP No.	SP Name	Def.	Max.	Min.
        4-938-001	ACS:Edge Mask Copy:Sub LEdge	10	0	31

        4-938-007	ACS:Edge Mask Scan:Main LEdge	15	0	31
        4-938-008	ACS:Edge Mask Scan:Main TEdge	15	0	31

        
        

        

        [A]: Sub scan direction: leading edge (left) [B]: Main scan direction (front)

        [C]: Sub scan direction: leading edge (right)

        Troubleshooting

        [D]: Main scan direction (rear) [E]: Paper

        [F]: ACS area excluded from judgment

        
        

        • Because the edge of the original is subject to noise, color misjudgment may occur after setting these SPs smaller than the defaults. In this case, in order to avoid complaints concerning extra cost, be sure to ask the customer for permission before changing these SP settings.

   2. MISJUDGMENT FOR AUTO COLOR SELECTION (E.G. WHEN USING PAPER WHICH HAS A STRONG BLUE COMPONENT)

      Causes

      The strong blue component of the paper causes the difference in RGB values to be relatively large. As a result, ACS mistakenly judges that the paper is blue.

      • ACS makes this judgment based on the RGB thresholds set in SP mode.

        Solutions

        Change the setting of SP4-939-001 (ACS:Color Range) until ACS works correctly.

        
        

      • Change the value of the SP to “-1” or “-2” when a black and white document is misjudged as a color document.

6.20 OTHER TROUBLESHOOTING

6.20.1 WHEN FLUORESCENT/ LED LAMPS FLICKER

Problem

Under the usage environment of this machine, at the placement location, fluorescent and/or LED lamps flicker.

Causes

As a result of the voltage drop occurs, when the fusing lamp is applied an electrical current. It depends on the electrical power environment, at the customer's placement location.

Solutions

The procedure varies by the flicker occurrence timing. So check the occurrence timing, and do the procedure that matches the timing.
