Image forming apparatus, image forming system, and image formation control program

An image forming system comprising:

• an image former that forms an image on a transfer paper sheet;
• a colorimeter that reads the image formed on the transfer paper sheet;
• a conveyor that conveys the transfer paper sheet during the image formation at the image former and the reading of the image at the colorimeter;
• and
• a controller that controls the formation of the image on the transfer paper sheet, and the reading and the conveyance of the image,
• the image forming system being provided in different devices to which the image former and the colorimeter are connected,
• wherein
• when a first conveyance velocity is a velocity at which the transfer paper sheet is conveyed when the image is formed by the image former, and is higher than a velocity set for conveying the transfer paper sheet when the image is read by the colorimeter,
• a second conveyance velocity is a velocity that is lower than the first conveyance velocity and is set as a velocity at which the transfer paper sheet is conveyed when the image is read by the colorimeter, and
• a long paper sheet having a longer transfer sheet length in a conveying direction than a predetermined threshold value is used as the transfer paper sheet in an adjustment mode in which an adjustment image formed on the transfer paper sheet is read by the colorimeter, the controller
• controls the image former and the conveyor, to form the adjustment image on the transfer paper sheet being conveyed at the second conveyance velocity, and
• controls the colorimeter and the conveyor, to read the adjustment image formed on the transfer paper sheet while the transfer paper sheet is being conveyed at the second conveyance velocity.

A non-transitory recording medium storing a computer readable image formation control program for controlling an apparatus that includes:

• an image former that forms an image on a transfer paper sheet;
• a colorimeter that reads the image formed on the transfer paper sheet;
• a conveyor that conveys the transfer paper sheet in the image formation at the image former and the reading of the image at the colorimeter;
• and
• a controller that controls the formation of the image on the transfer paper sheet, and the reading and the conveyance of the image,
• wherein
• when a first conveyance velocity is a velocity at which the transfer paper sheet is conveyed when the image is formed by the image former, and is higher than a velocity set for conveying the transfer paper sheet when the image is read by the colorimeter,
• a second conveyance velocity is a velocity that is lower than the first conveyance velocity and is set as a velocity at which the transfer paper sheet is conveyed when the image is read by the colorimeter, and
• a long paper sheet having a longer transfer sheet length in a conveying direction than a predetermined threshold value is used as the transfer paper sheet in an adjustment mode in which an adjustment image formed on the transfer paper sheet is read by the colorimeter,
• the computer readable image formation control program causes a computer of the image forming apparatus to perform:
• controlling the image former and the conveyor, to form the adjustment image on the transfer paper sheet being conveyed at the second conveyance velocity;
• and
• controlling the colorimeter and the conveyor, to read the adjustment image formed on the transfer paper sheet while the transfer paper sheet is being conveyed at the second conveyance velocity.
