Abstract: A cartridge providing system includes a printer ejecting, onto a printing medium, a liquid (recording material) supplied from a cartridge, and a server managing provision of the cartridge to a user that uses the printer. The server manages user stock data, which is data associating a stock of the cartridges held by the user with usage expiry dates thereof, and vendor stock data, which is data associating a stock of the cartridges held by a sales company providing the cartridge to the user with usage expiry dates thereof. When the sales company provides the cartridge to the user, the server determines, based on the vendor stock data and the user stock data, the cartridge of which usage expiry date is to be provided from among the stock of the cartridges held by the sales company.

Abstract: A cartridge providing system includes a printer ejecting, onto a printing medium, a liquid (recording material) supplied from a cartridge, and a server managing provision of the cartridge to a plurality of users that use the printer. The server determines whether an unused stock, which is a stock that remains unused for a first period or longer, is present in a stock of cartridges held by each of the plurality of users. In a case in which it is determined that an unused stock is present in the stock held by a first user of the plurality of users, when a period until a usage expiry date of the unused stock is less than a first threshold value, the server specifies a second user, of the plurality of users, to be provided with the unused stock, based on user stock data in which the stock of cartridges held by the user is registered, and on usage amount data indicating a usage amount of the cartridge.

Abstract: A cartridge providing system includes a printer ejecting a liquid (recording material) supplied from a cartridge, and a server managing provision of the cartridge to users that use the printer. Based on user stock data of each of the users, the server determines whether an unused stock, which is a stock that remains unused for a first period or longer from a start of holding, is present in a stock of the cartridges held by each of the users. If it is determined that an unused stock is present in the stock held by a first user, when a period until a usage expiry date of the unused stock is less than a first threshold value, the server sets a collection recommendation flag to the unused stock in the user stock data of the first user, the collection recommendation flag indicating the cartridge recommended for collection.

Abstract: A printer includes a recording unit, a glue belt, a pressing roller, a blowing unit, an ion application unit, and a charging unit. The glue belt includes an outer peripheral surface configured to support a medium. The pressing roller is provided upstream of the recording unit in a circumferential direction, and presses the medium against the outer peripheral surface. The blowing unit is provided upstream of the recording unit and downstream of the pressing roller in the circumferential direction and configured to blow a gas toward the outer peripheral surface. The ion application unit applies ions having a positive polarity to the gas blown onto the outer peripheral surface. The charging unit charges a front surface configured to come into contact with the medium so that the polarity of the potential of the front surface is the same as the polarity of the ions applied to the gas.
