Replacing the PCU without Inputting the Correction Value

Judge whether or not you set New PCU detection, do the following procedure:

Case 1: When you set SP3-701 to “1”

  • Input the PCU correction value.

  • Execute process control manually with SP3-011-001 in order to adjust the machine settings with the PCU correction value.

    • If you replace the PCU by entering the PCU correction value, the process control is automatically executed.

Case 2: When you did not set SP3-701 to “1”

  • Set SP3-701 to “1”.

  • Check the correction value printed on the label attached to the new PCU. Input the correction value into the SP number corresponding to the color to be replaced. (For the label and the correction value, refer to the following.)

 

After doing the above procedure, turn the power OFF. Note that process control will start automatically.

 

Before Replacing a Development Unit

  • Replacing the development unit resets not only the development unit counter but also the PCU counter. However, if you change the SP setting (SP3-701) before you replace the development unit, the PM counter of the development unit is reset, but the PM counter of the PCU is not reset.

  • Therefore, before you replace the development unit, the manual new unit setting SP3-701 must be done. Doing these in the wrong order will reset the counter of the PCU also.

Before replacing the development unit, do the procedure shown below.

  • Set SP3-701: New unit detection to “1”.
