28 Replacing Consumables and Maintenance Kit Replacing the Toner Cartridge Do not incinerate spilled toner or used toner. Toner dust is flammable and might ignite when exposed to an open flame. Disposal should take place at an authorized dealer or an appropriate collection site. If you dispose of the used toner cartridges yourself, dispose of them according to local regulations. Do not store toner, used toner, or toner containers in a place with an open flame. The toner might ignite and cause burns or a fire. Keep toner (used or unused) and the toner cartridge out of reach of children. If toner or used toner is inhaled, gargle with plenty of water and move into a fresh air environment. Consult a doctor if necessary. If your skin comes into contact with toner or used toner, wash the affected area thoroughly with soap and water. If toner or used toner gets into your eyes, flush immediately with large amounts of water. Consult a doctor if necessary. If toner or used toner is swallowed, dilute by drinking a large amount of water. Consult a doctor if necessary. Avoid getting toner on your clothes or skin when removing a paper jam or replacing toner. If your skin comes into contact with toner, wash the affected area thoroughly with soap and water. If toner gets on your clothing, wash with cold water. Hot water will set the toner into the fabric and may make removing the stain impossible. When handling toner cartridges, never stand them up on either end or position them upside down. Store toner cartridges in a cool dark place. Actual printable numbers vary depending on image volume and density, number of pages printed at a time, paper type and size, and environmental conditions such as temperature and humidity. Toner quality degrades over time. You may have to replace the toner cartridge prematurely. We recommend you prepare a new toner cartridge beforehand.

59 Cleaning and Adjusting the Printer Cautions to Take When Cleaning Do not remove any covers or screws other than those specified in this manual. Some parts of the machine are at a high voltage and could give you an electric shock. Also, if the machine has laser systems, direct (or indirect) reflected eye contact with the laser beam may cause serious eye damage. When the machine needs to be checked, adjusted, or repaired, contact your service representative. Do not take apart or attempt any modifications to this machine. There is a risk of fire, electric shock, explosion or loss of sight. If the machine has laser systems, there is a risk of serious eye damage. When removing misfed paper, do not touch the fusing unit because it could be very hot. Clean the printer periodically to maintain fine printing. Dry wipe the exterior with a soft cloth. If dry wiping is not enough, wipe with a soft, wet cloth that is wrung out well. If you still cannot remove the stain or grime, use a neutral detergent, and then wipe over with a well-wrung wet cloth, dry wipe, and let it dry. To avoid deformation, discoloration, or cracking, do not use volatile chemicals, such as benzine and thinner, or spray insecticide on the printer. If there is dust or grime inside the printer, wipe with a clean, dry cloth. You must disconnect the plug from the wall outlet at least once a year. Clean away any dust and grime from the plug and outlet before reconnecting. Accumulated dust and grime pose a fire hazard. G _1.00 Copyright

62 Cleaning and Adjusting the Printer Correcting the Color Gradation Color gradation during color printing changes slightly, depending on a number of factors. If you print the same file repeatedly or toner was recently replaced, changes may occur in color tones. When this happens, to obtain suitable print results, color gradation can be corrected, although it is not usually necessary to make any particular settings. If suitable results cannot be obtained after a single operation, repeat the correction several times, as needed. Corrections to color gradation will be applied to all user jobs. Use the same paper when printing a run of gradation corrections. If a different type of paper is used, corrections may not be apparent. This requires the use of the supplied Color Calibration Sample Sheet. Corrections to color gradation are performed in the following order: Set the Gradation Correction Value During printing, you can correct the gradation in two areas: bright part (highlight) and the medium (middle). The correction value for the highlight and the medium parts are set using Calibr.1 and Calibr.2 respectively. 62

63 Cleaning and Adjusting the Printer A Press the {Menu} key. The [Menu]screen appears. B Press the {U} or {T} key to display [Maintenance], and then press the {# Enter} key. Menu: Maintenance The maintenance menu appears. C Press the {U} or {T} key to display [Color Calibrate], and then press the {# Enter} key. If you perform only correction 2, proceed to step L. D Check [Start Calibr. 1] is displayed, and then press the {# Enter} key. E Check [Yes] is displayed, and press {# Enter} key to print gradation correction sheet 1. F Set the gradation correction value of the highlighted part using correction 1. For setting K (black) gradation, hold the correction value (0-6) for K of the correction value setting sheet 1 over the color sample (K) for gradation correction 1 of the Color Calibration Sample Sheet, and set the numerical value of the closest color using either the {U} or {T} key. Set the correction value using the supplied Color Calibration Sample Sheet and the gradation correction sheet 1 printed in the previous step. Set M (magenta), C (cyan), and Y (yellow) using the same method. Calibrate 1: K:3 M:3 C/Y:3/3 63

64 Cleaning and Adjusting the Printer Each time the {U} or {T} key is pressed, the value increases or decreases respectively, in increments of 1. The correction value can be set between 0 and 6. G Press the {# Enter} key after setting the K (black) gradation. The cursor shifts to M (magenta). Calibrate 1: K:2 M:3 C/Y:3/3 H Set the gradation correction values for M (magenta), C (cyan), and Y (yellow) using the same procedure as for the K (black). I If you finished all settings, ensure that the cursor is on the correction value for Y (yellow), and then press the {# Enter} key. Calibrate 1: K:2 M:2 C/Y:2/2 The example shows the display of the control panel when the correction value for each color is changed to 2. J Check [Yes] is displayed, and press the {# Enter} key to print the correction result. K Check gradation correction sheet 1. To save the correction values, check [Save and exit] is displayed and press the {# Enter} key. If you do not want to save the correction values after this procedure, press the {U} or {T} key to display [Exit don't save], and then press the {# Enter} key. If you complete this procedure without saving the correction values, the changes will not be applied to subsequent print jobs. Calibrate 1: Save and exit Calibrate 1: Exit don't save This concludes the setting for correction 1. Next, proceed to correction 2. L Press the {T} key to display [Start Calibr. 2], and then press the {# Enter} key. 64

65 Cleaning and Adjusting the Printer M Check [Yes] is displayed, and then press the {# Enter} key to print gradation correction sheet 2. N Perform the same operations as used for setting the gradation correction value using correction 1 to set the gradation correction value of the middle part using correction 2. O After completing all settings, press the {Online} key. The initial screen appears. Displays on the screen are just examples. Viewing the Color Calibration Sample Sheet and Gradation Correction Sheet The color gradation correction value setting sheet contains two color sample columns: the Sample 1 column for setting the highlight part and the Sample 2 column for setting the middle part. Similarly, there are two gradation correction sheets: Gradation correction sheet 1 for setting the highlight part and Gradation correction sheet 2 for setting the middle part. Gradation correction sheet 1 is used for calibration 1, while Gradation correction sheet 2 is used for calibration 2. Color sample and correction values The following explains how to view the color sample of the Color Calibration Sample Sheet and the correction values of the gradation correction sheet. This explanation uses setting K (black) as an example. The setting method for M (magenta) is similar. For C/Y (cyan/yellow), the correction value is determined based on combinations of these two colors, although panel settings are made for each color. 65

66 Cleaning and Adjusting the Printer Hold the correction value (0-6) for K of the correction value setting sheet over the color sample of gradation correction 1 of the Color Calibration Sample Sheet and search for a corrected color closest to that of the color sample, and then set its correction value using the operation panel. The currently set correction value is printed in red. 66

67 Cleaning and Adjusting the Printer Relationship between gradation correction sheet and display The printed gradation correction sheet and display correspond as shown in the following diagram. The gradation correction sheets are used to determine the correction values for the colors K (black), M (magenta), C (cyan), and Y (yellow). These values are set using the control panel. XXXX represents the printer model name. A K (black) correction values Adjust the printed color when only black toner is used. The currently set correction value is printed in red. B M (magenta) correction values Adjust the printed color when only magenta toner is used. The currently set correction value is printed in red. C C (cyan)/y (yellow) correction values Correct the color printed when cyan and yellow are used. For C/Y (cyan/yellow), the correction value is determined based on a combination of these two colors, although settings are made for separately each color. D K, M, C/Y The numerical value set at time of gradation correction sheet printing is displayed. This corresponds to the numerical value set using the operation panel. Resetting the gradation correction value to the initial value Reset the correction value default. 67
