Image forming apparatus having a usage restriction and image forming system including the same

摘要

An image forming apparatus has a plurality of functions that includes at least one predetermined function on which a usage restriction is imposed. The image forming apparatus includes a printing section and a control section. The printing section supplies toner to an electrostatic latent image to develop the electrostatic latent image into a toner image and print the toner image on a sheet. The control section counts sheets printed by the printing section and removes the usage restriction on the at least one predetermined function when a cumulative number of sheets printed by the printing section reaches a predetermined number.

主权项

1. An image forming apparatus having a plurality of functions that includes at least one predetermined function on which a usage restriction is imposed, the image forming apparatus comprising:
a printing section configured to supply toner to an electrostatic latent image to develop the electrostatic latent image into a toner image and print the toner image on a sheet; and a control section configured to
count sheets printed by the printing section; andremove the usage restriction on the at least one predetermined function when a cumulative number of sheets printed by the printing section reaches a predetermined number; wherein the at least one predetermined function comprises two or more predetermined functions on each of which a usage restriction is imposed, and each time the cumulative number of sheets increases by a predetermined number, the control section removes a usage restriction that is not yet removed among the usage restrictions on the two or more predetermined functions.
