Image forming apparatus having a plurality of image forming units, initial adjustment method for the image forming apparatus, and computer readable medium recording program for causing the image forming apparatus to perform initial adjustment

An initial adjustment method for an image forming apparatus, wherein said image forming apparatus includes

• a main body including a main body storage part,
• a first image forming unit removably attached to said main body and including a first storage part, and
• a second image forming unit removably attached to said main body,
• said initial adjustment method comprising the steps of:
• storing in said first storage part first information indicative of whether or not an initial adjustment of said first imaging forming unit has been completed;
• storing in said main body storage part second information indicative of a usage history of said second image forming unit, wherein the second image forming unit does not have a storage part storing second information;
• determining whether or not said first information stored in said first storage part and said second information stored in said main body storage part satisfy respective prescribed conditions;
• and
• causing said first and second image forming units to be agitated simultaneously as the initial adjustment when said first information indicates that the initial adjustment of said first image forming unit has not been completed and said second information indicates that the second image forming unit corresponds to an unused state.

A non-transitory computer readable medium storing a program for causing an image forming apparatus to perform an initial adjustment, wherein said image forming apparatus includes

• a main body including a main body storage part,
• a first image forming unit removably attached to said main body and including a first storage part,
• a second image forming unit removably attached to said main body, and
• a controller controlling operations of said image forming apparatus,
• said program causing said controller to perform the steps of:
• storing in said first storage part first information indicative of whether or not an initial adjustment of said first imaging forming unit has been completed;
• storing in said main body storage part second information indicative of a usage history of said second image forming unit, wherein the second image forming unit does not have a storage part storing second information;
• determining whether or not said first information stored in said first storage part and said second information stored in said main body storage part satisfy respective prescribed conditions;
• and
• causing said first and second image forming units to be agitated simultaneously as the initial adjustment when said first information indicates that the initial adjustment of said first image forming unit has not been completed and said second information indicates that the second image forming unit corresponds to an unused state.
