Cleaning the Machine

Note the following before cleaning your machine:

  • Make sure no documents are stored in memory when you turn OFF the main power switch and disconnect the power cord.
  • Use a soft cloth to avoid scratching the components.
  • Do not use tissue paper, paper towels, or similar materials for cleaning; they can stick to the components or generate static charges.

Remark
  • Never use volatile liquids such as thinner, benzene, acetone, or any other chemical cleaner to clean the machine. These can damage the machine components.
  • You cannot send or receive documents when the main power switch is turned off or the power cord is disconnected.
  • If the main power switch is turned OFF, all jobs waiting in the print queue will be erased.
  • Documents received into memory and documents stored for delayed send will be retained for approximately 60 minutes after the power cord has been disconnected.
  • When you turn OFF the main power switch, the documents stored in memory will be erased. To check the jobs stored in memory, see the following:

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

Return to Overview

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.
  • Prepare a new toner cartridge.
  • Replacing the toner cartridge is recommended before performing a bulk printing.
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

Return to Overview

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.
<Replace the toner cartridge. (Yellow)>: Replace the yellow toner cartridge.
<Replace the toner cartridge. (Cyan)>: Replace the cyan toner cartridge.
<Replace the toner cartridge. (Magenta)>: Replace the magenta toner cartridge.

  1. Open the front cover by using the handle (A).
  • The toner cartridges are installed in order of black, yellow, cyan, and magenta from the top as shown in the figure.

  1. To prevent damage to the transfer belt of the delivery feeder unit (A), cover the thin plastic belt with paper (A4 size paper is recommended) as shown in the figure and be sure that they do not move out of place.
  • When installing or removing the toner cartridges, be sure to place paper on the transfer belt (A) of the delivery feeder unit to protect the belt.
  • Do not place any object on or touch the transfer belt (A) of the delivery feeder unit. The transfer belt (A) of the delivery feeder unit has a self cleaning function, therefore, do not clean the belt even when the toner is on it. If the delivery feeder unit is broken or transfer belt (A) is damaged, this may result in misfeeds or deterioration in print quality.



  1. Hold the blue tabs on the both sides of toner cartridge, and pull it horizontally.
  • Do not touch the high-voltage contact (A) or the electrical contacts (B), as this may result in damage to the printer.



  1. Take the new toner cartridge out of the protective bag after taking it out of the package.

There is a cut near the arrow on the protective bag, so you can open it by hand. However, if you cannot open it by hand, use scissors to open the protective bag so as not to damage the toner cartridge.

  1. Gently rock the toner cartridge several times to evenly distribute the toner inside.
  1. Place the toner cartridge on a flat surface, fold back the tab of the sealing tape (A) located at left side of the toner cartridge.
  1. Remove the sealing tape (approx. 18 7/8 inch long) gently by hooking your fingers into the tab and pulling it out straight in the direction of the arrow.
  • Do not pull the seal out at an angle.

  • Do not open the drum protective shutter (A).

  • If toner is adhered to the removed seal, be careful not to dirty your hands or clothing by touching it.
  • If your hands or clothes get dirty from touching the toner, wash them immediately in cold water. Do not use hot water. Doing so may cause the toner to set permanently.
  1. Hook your finger into the tab and remove the packing materials (A) located at right side of the toner cartridge.
  1. Hold the toner cartridge properly by the blue tabs on the both sides with the arrowed side facing up.
  • Do not hold the toner cartridge in a manner that is not directed in this procedure.

  1. Align (A) of the toner cartridge that you want to replace with the slots (B) to which the label of the same color is attached, then insert the cartridge until it stops.
  1. After removing all the packing materials on the each toner cartridges and installing the cartridges, remove the paper on the transfer belt of the delivery feeder unit.
  • When removing the paper, be careful not to touch or damage the transfer belt of the delivery feeder unit.
  1. Close the front cover.
  • If the front cover does not close properly, do not force it to close. Open the cover and make sure the toner cartridge is properly set in the machine.


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.


Remark
  • It is recommended that you select <Full Correction> when performing an automatic gradation correction. Select <Quick Correction> for a quick, but less complete adjustment between regular full adjustment recalibrations.

Correcting Gradation

Return to Overview

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:


  • Full Correction (Recommended)

This recalibrates the gradation for both copies and prints.

  • Quick Correction

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.

  • Copy Image Correction

This recalibrates the gradation for copies. If the recalibration is insufficient, perform a Full Correction.



Full Correction

Return to Overview

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.


Remark
  • Make sure that you place the test prints properly. Accurate recalibrations of the gradation, density, and color settings of the machine cannot be made if the test prints are not scanned correctly.
  • Two test prints are output by the machine during this adjustment. Make sure that a sufficient supply of A4 or LTR paper is loaded into the machine before starting this procedure.
  • Test prints are not counted as part of the copy or print total page counts.
  • It takes approximately five minutes to perform the Full Correction.
  • For an accurate adjustment, do not use colored paper, transparencies, or labels.
    It is recommended that you use plain white paper when performing a Full Correction.
  • If you set <Color> in <Paper Type> of <Paper Settings>, Full Correction cannot be performed. To perform a Full Correction, set <Paper Type> other than <Color>. For instructions on how to set the paper type, see "Setting Paper Size and Type."
