Page 54 5. Image Quality Problem: Lines Vertical Black (color) Streaks (2) Extended, blurred black (color) streaks parallel to the paper feed direction appear. The streaks also appear randomly in the margins. CWH401 Cause: If the temperature or humidity is low, remaining toner might be missed by the cleaning blade of the ITB cleaning unit or paper transfer unit, causing streaks to appear sporadically.
Page 55 Streaks Vertical Black (color) Streaks (3) A streak appears in parallel to the paper feed direction. This may occur on half-tone images. DFP486 Cause: There is a trace (streak) of the paper edge on the fusing belt.

Page 66 5. Image Quality Problem: Lines Bands Banding: General Density fluctuation occurs periodically in the vertical direction to the paper feed direction. CWH407 Cause: Density fluctuation occurs when the pitch phase between the charge roller, developing roller, paper transfer roller, and photoreceptor is different. Solution: The solution depends on the length of intervals whereby the density fluctuation occurs.
Page 67 Bands Go to the next step. Print a full-page, half-tone A3 sheet for each of cyan, magenta, yellow, and black, and then measure by a ruler, etc., the intervals between the spots affected by density fluctuation. Perform the following solution. If the applicable interval is not listed, contact your service representative.

Page 288 9. Post-Processing Option Troubleshooting • Coated or other paper producing higher paper-to-paper friction is used. • Thin or other limp paper is used. Solution: Reduce the number of sheets to be stapled. In the [Finishing: Finisher] group on the [Adjustment Settings for Operators] menu, select 0606: [Number of Sheet Align for Stapling], and reduce the number of sheets to be stapled.
Page 289 Finisher Select [Magazine]. Press [OK]. Press [Edit / Color]. Press [Margin Adj.]. Specify left margin on the front side to 5 mm and right margin on the back side to 5 mm. Paper Edges Are Stained Cause: While back curls are removed, the toner adhesion becomes insufficient when the fusing pressure roller is used on the paper, allowing the toner to stain the anti-static brush.
Page 290 9. Post-Processing Option Troubleshooting Multi-Folding Unit Inaccurate Folding (Folding Deviation) 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. For multi-sheet folding, change the folding position using the following settings in the [Finishing: Fold] group on the [Adjustment Settings for Operators] menu: •...
Page 291 Multi-Folding Unit Folding Deviation Cause: Depending on paper hardness, folding deviations (skewed folding) may appear. A deviation may appear if the edge dimensions of the parts between folds are different. For example, in the following illustration, the dimensional difference between the top (L2[2]) and bottom (L2[1]) edges is a deviation.

Page 296 9. Post-Processing Option Troubleshooting CEZ571 This will produce paper stain 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. Solution: Clean the blade. Open the front cover of the multi-folding unit. Pull the multi-folding unit out.
Page 297 Multi-Folding Unit Wipe the tip and top of the blade with a soft dry cloth. Be careful not to damage the blade. CEZ513 After cleaning, restore the machine so that it resumes operation. Apply multi-sheet folding and print 3-5 copies. The paper stain will disappear. Edges of Letter Fold Bent When letter folding is applied, the edge of the inner flap may become bent.

Page 300 9. Post-Processing Option Troubleshooting Folded Sheets Are Not Stacked Properly Cause: If a large number of half-folded multi-sheet is delivered, the edge of the sheets may bulge and some part of the edge will be swollen. If this happens, other sheets loaded on the bulged paper may turn over in the output tray.
Page 301 Multi-Folding Unit For details about using the Z-fold support tray for multi-folding unit, see "Preparation" supplied with the machine. • If the Z-fold support tray for the multi-folding unit is attached, folded paper such as letter-folded paper or gate-folded paper will not turn over in the output tray when delivered.
Page 302 9. Post-Processing Option Troubleshooting Ring Binding • Be sure not to exit from Energy Saver mode or to switch the machine on when the ring binder door is open and the binding unit is disconnected. Doing so will affect initialization, causing the ring binder function to become unavailable (although other functions will be unaffected).
Page 303 Buffer Pass Unit Buffer Pass Unit The Fan Is Noisy You can change the buffer pass unit fan activation setting according to the type of paper and ambient temperature. In the [Machine: Paper Feed/ Output] group on the [Adjustment Settings for Operators] menu, change the value in 0311: [Buffer Pass Unit Fan Activation Setting].
Page 304 9. Post-Processing Option Troubleshooting High Capacity Stacker Delivered Sheets Are Severely Curled Cause: Sheets with downward curls cause strong friction on the 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, so that the delivered sheets may be curled when loaded.

Page 310 9. Post-Processing Option Troubleshooting The Paper Press Leaves an Impression on the Paper Cause: The pressure applied by the paper press leaves an impression on the paper. Solution: Insert an extra sheet of paper between the paper press and the paper stack. Paper Pressed Down Insufficiently Cause: The screws on the handle of the paper cart and the bolts at its bottom are loose.
Page 311 Other Post- Processing Options Other Post- Processing Options Scratched Images and Stained Paper Edges Scratched images or stained paper edges appear. CNT008 Cause: When a relatively stiff, thick paper is delivered, the entrance guide board for the transfer unit is warped toward the intermediate transfer belt due to the stiffness of the paper.

Page 319 10. Improving Throughput Reducing the Waiting Time Prior to Printing After receiving a print job, the machine usually stops to let the fusing temperature reach an appropriate level for printing.

Page 321 Improving Throughput when Continuously Performing Black and White and Color Printing Improving Throughput when Continuously Performing Black and White and Color Printing When a combination of black-and-white, full-color and special color printing is performed, switching color modes takes time, resulting in insufficient throughput. Optimize the amount of sheets the machine prints in the current color mode before switching to another mode.
Page 322 10. Improving Throughput Value Behavior 10 (Maximum) • When black-and-white printing is performed after full color printing, full color mode switches to black-and-white mode after 10 black-and-white sheets are printed in full color mode. • When black-and-white printing is performed after special color printing, special color mode switches to black-and-white mode after 10 black- and-white sheets are printed in special color mode.
Page 323 11. Advanced Instructions Operating Procedure for Color Calibration To improve color reproduction and achieve color output with consistent quality, follow this procedure. It is recommended to perform color calibration for each print job. To improve CMYK image reproduction, adjust image density, and then perform calibration. Also, you can improve mixed color reproduction by adjusting image density and color registration and performing calibration.
