Paper feeding parameter management system

A paper feeding parameter management system, comprising:

• air paper feeding devices each of which includes an air paper feeder that feeds a paper sheet by sending air to and attracting the paper sheet, and switches paper feeding parameters in the air paper feeder;
• and
• a management device connected to the air paper feeding devices via a communication network,
• wherein
• each of the air paper feeding devices includes:
• a paper type information obtainer that obtains paper type information on paper sheets targeted for feeding, and
• a first hardware processor that adjusts a paper feeding parameter in the air paper feeder, and transmits the paper type information obtained by the paper type information obtainer, the adjusted paper feeding parameter, and a conveyance result of feeding the paper sheets targeted for feeding using the adjusted paper feeding parameter to the management device, and
• the management device includes a second hardware processor that (i) causes a memory to hold an adjustment result in which the paper type information, the paper feeding parameter, and the conveyance result transmitted from each of the air paper feeding devices are associated, and (ii) refers to the adjustment result held in the memory to set, for an air paper feeding device targeted for processing among the air paper feeding devices, a paper feeding parameter corresponding to the paper type information obtained by the paper type information obtainer of the air paper feeding device targeted for processing on a basis of the conveyance result corresponding to the paper feeding parameter.
