Interior |
Clean the machine's print area periodically to prevent toner powder and paper dust from accumulating inside. |
Cleaning the Fixing Unit |
Cleaning the Fixing Unit |
If black streaks appear on printed output, the fixing unit may be dirty. Also, you should use the Fixing Unit Cleaning procedure every time the toner cartridge is replaced. Print the cleaning pattern on A4 paper for cleaning the fixing unit. |

Replacing the Toner Cartridges |
This section describes how to replace or handle the toner cartridges and precautions on storing them. |
When a Message Appears |
Replacing the Toner Cartridge with a New One |
When a Message Appears |
Toner cartridges are consumable products. When the time to replace the toner cartridge is nearing or the toner runs out while using this machine, a message appears on the display. |
Message | When it is Displayed | Contents and Remedies |
Prepare a new toner cartridge. (XXX*) | When a toner cartridge needs to be replaced soon. |
|
Check the XXX* toner. | A toner cartridge that cannot guarantee print quality because it has reached the end of its life etc., or a toner cartridge that has already been spent may be set. | Continued use of this toner cartridge may cause the machine to malfunction. Replacing of the toner cartridge is recommended. |
Replace the toner cartridge. (XXX*) | When the toner runs out. | Replace the toner cartridge of the indicated color. Incidentally, even if any of Yellow, Cyan or Magenta toner runs out, black and white printing can still be performed if Black toner remains. |
* XXX indicates "Black", "Yellow", "Cyan", or "Magenta". |
Replacing the Toner Cartridge with a New One |
If any of the following messages appears, replace the toner cartridge of the indicated color with a new one. <Replace the toner cartridge. (Black)>: Replace the black toner cartridge. |

Adjusting the Machine |
This section describes how you can adjust the settings of the machine to improve print quality and to prevent paper jams, which may occur when a variety of functions are used. It is recommended that you perform these settings regularly to prevent a number of problems from occurring. |

Correcting Gradation |
You can recalibrate the machine when you notice irregularities in the color of the copies or prints, such as when copies turn out to be different from the original in gradation, density, or color. The following three types of gradation corrections can be made: |
This recalibrates the gradation for both copies and prints.
This is a simple and temporary correction until next time a Full Correction is performed. Quick Correction recalibrates the gradation for both copies and prints. If the recalibration is insufficient, perform a Full Correction.
This recalibrates the gradation for copies. If the recalibration is insufficient, perform a Full Correction. |
Full Correction |
This is a precise recalibration for the machine's gradation, density, and color settings. The procedure involves making test prints and placing them on the platen glass for scanning. Once this is complete, the machine automatically corrects the irregularities. |

Adjusting Toner Fixing (Image Special Processing) |
Areas with high toner density may appear blotched when printed or may not print properly, because the toner cannot be fixed on the printing paper. If this happens, set this item to <Level 1>. If that does not solve the problem, set this item to <Level 2>. |
