Printing devices may form images on media using toner stored in a toner cartridge. The toner in the toner cartridge may be depleted as the toner is used to form the images. In some types of printing devices, the toner cartridge may be removed from the toner cartridge and replaced after the toner has been depleted. In other types of printing devices, the toner cartridge may include a refill port through which toner may be supplied into the toner cartridge.
Features of the present disclosure are illustrated by way of example and not limited in the following figure(s), in which like numerals indicate like elements, in which:
For simplicity and illustrative purposes, the present disclosure is described by referring mainly to examples. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present disclosure. It will be readily apparent however, that the present disclosure may be practiced without limitation to these specific details, In other instances, some methods and structures have not been described in detail so as not to unnecessarily obscure the present disclosure.
Throughout the present disclosure, the terms “a” and “an” are intended to denote at least one of a particular element. As used herein, the term “includes” means includes but not limited to, the term “including” means including but not limited to. The term “based on” means based at least in part on.
Disclosed herein are toner refill apparatuses, systems, and methods in which a controller may activate an actuator to manipulate a valve mechanism and control supply of toner from the toner refill apparatus into a toner cartridge. Particularly, the actuator may engage the valve mechanism when the toner refill apparatus is properly inserted into a refill port of a printing device. In addition, the controller may activate the actuator to cause the valve mechanism to move from a position in which the valve mechanism blocks a discharge opening in the toner refill apparatus to a position in which toner may flow through discharge opening. In some examples, the controller may automatically activate the actuator based on a determination that the toner refill apparatus has properly been inserted into the refill port.
Through implementation of the features of the present disclosure, a valve mechanism of a toner refill apparatus may automatically be controlled following insertion by a user of the toner refill apparatus into the refill port. In this regard, the user may not perform other actions, such as rotating the toner refill apparatus, following insertion of the toner refill apparatus into the refill port. As such, a toner cartridge may be refilled with toner from a toner refill apparatus with a reduced or limited number of user actions, which may result in a reduced number of errors that may occur during toner refilling operations.
Reference is first made to
The apparatus 100, which may also be termed a toner refill apparatus 100, may house toner 102 and may include features to deliver the toner 102 to a refillable toner cartridge (not shown). Thus, for instance, the apparatus 100 may be employed to refill the toner cartridge of a printing device (not shown) with toner 102 instead of replacing the toner cartridge with a new toner cartridge. The toner 102 may be a powder mixture that the printing system may be used to print black and/or color text and images on media, such as paper. The printing system may be a laser printer, a photocopier, a multifunction printing device, or the like. The features of the printing system are depicted with dashed lines to denote that the printing system may not form part of the apparatus 100.
The apparatus 100 may include a chamber 104 to house the toner 102. The chamber 104 may be formed of any suitable material including a plastic, a metal, a ceramic, and/or combinations thereof. In addition, the chamber 104 may be sized to house an amount of toner appropriate for refilling a toner cartridge and may thus vary for different types of toner cartridges. The chamber 104 may further include a shape that may facilitate handling by a user for movement as well as for insertion into a printing system.
As shown, the chamber 104 may include an insertion section 106 including a discharge opening 108 through which the toner 102 may flow out of the chamber 104. The apparatus 100 may include a valve mechanism 110 positioned at the discharge opening 108. The valve mechanism 110 may prevent or block the flow of the toner 102 through the discharge opening 108 when the valve mechanism 110 is in a first (e.g., closed) position. In addition, toner 102 may flow past or through the valve mechanism 110 when the valve mechanism 110 is in a second (e.g., open) position.
The apparatus 100 may further include an electronic chip 112 that may, for instance, store data pertaining to the apparatus 100. The data pertaining to the apparatus 100 may include identification information of the apparatus 100, which may include manufacturer information, serial number, toner type, toner color, and/or the like. In some examples, the data may be encrypted to reduce unauthorized access to the data.
According to examples, the apparatus 100 may be inserted into a refill port 120 of the printing device when a toner cartridge is to be refilled. Particularly, the insertion section 106 may be inserted into the refill port 120 as shown in
In addition, when the insertion section 106 is properly inserted into the refill port 120, an actuator 124 may engage the valve mechanism 110. That is, for instance, the insertion section 106 may be considered as being properly inserted into the refill port 120 when the electronic chip 112 is in electrical contact with the electrical circuit component 122 and the actuator 124 is engaged with the valve mechanism 110. In some examples, the actuator 124 may include gearing or another mechanism that may be coupled to a motor such that, when the motor is activated, the actuator 124 may cause the valve mechanism 110 to move between a first position in which toner 102 flow is prevented and a second position in which toner 102 flow is enabled.
According to examples, the printing device may include a controller 126 that may be connected to the electrical circuit component 122 and the actuator 124. The controller 126 may control operations of the actuator 124 based on determinations as to whether the insertion section 106 is properly inserted into the refill port 120. The controller 126 may additionally or alternatively control operations of the actuator 124 based on other factors, such as, for instance, the apparatus 100 being authenticated using data stored in the electronic chip 112. The controller 126 may be a semiconductor-based microprocessor, a central processing unit (CPU), an application specific integrated circuit (ASIC), a field-programmable gate array (FPGA), and/or other hardware device. In some examples, the controller 126 may determine that the actuator 124 is to be activated based on a determination that the insertion section 106 has properly been inserted into the refill port 120.
Turning now to
As shown in
The controller 126 may determine that the apparatus 100 has properly been inserted into the refill port 120 based on a detection of the electrical connection between the electrical circuit component 122 and the electronic chip 112. That is, in some examples, the electronic chip 112 may complete an electrical circuit (e.g., current flow) of the electrical circuit component 122 with the controller 126 and the controller 126 may detect the completion of the electrical circuit. In other examples, the electronic chip 112 may break an electrical circuit of the electrical circuit component 122 with the controller 126 and the controller 126 may detect the breaking of the electrical circuit. In any of these examples, the controller 126 may equate the completion or breaking of the electrical circuit with the proper insertion of the insertion section 106 into the refill port 120.
In some examples, the controller 126 may automatically activate the actuator 124 based on a determination that the insertion section 106 has properly been inserted into the refill port 120. In other examples, the controller 126 may wait until a further user action is performed prior to activating the actuator 124. Particularly, and as shown in
According to examples, a movable cover 214 may be provided in the refill port 120. In these examples, the actuator 124 (and/or another actuator) may also engage the movable cover 214 and may move the movable cover 214 as the actuator 124 moves the valve mechanism 110. The actuator 124 may move the movable cover 214 into a position that may enable the toner 102 to flow through the movable cover 214 and into the toner cartridge 212.
As shown in
In other examples, the valve mechanism 110 and/or the movable cover 214 may be other types of valve mechanisms, e.g., valve mechanisms that may be moved between a first vertical position that may block toner flow and a second vertical position that may enable toner flow, valve mechanisms that may slide from one position to another, and/or the like.
As further shown in
In other examples, and as shown in
Following the flow of the toner 102 out of the apparatus 100 and into the toner cartridge 212, the controller 126 may activate the actuator 124 again to move the valve mechanism 110 and the movable cover 214 to closed positions.
Various manners in which the controller 126 may operate are discussed in greater detail with respect to the method 300 depicted in
At block 302, the controller 126 may determine whether a toner refill apparatus 100 is properly inserted into a refill port 120 in fluid communication with a toner cartridge 212. As discussed herein, an actuator 124 may contact a valve mechanism 110 of the toner refill apparatus 100 when the toner refill apparatus 100 is properly inserted into the refill port 120. As also discussed herein, the controller 126 may determine that the toner refill apparatus 100 is properly inserted into the refill port 120 based on an electrical connection being established or removed between an electrical circuit component 122 in the refill port 120 and an electronic chip 112 on the apparatus 100.
At block 304, in addition or alternatively, based on a determination that the toner refill apparatus 100 is properly inserted into the refill port 120, the controller 126 may determine whether a release mechanism 220 on the toner refill apparatus 100 has been manipulated. The controller 126 may determine whether the release mechanism 220 has been manipulated based on a determination as to whether an electrical connection, e.g., current flow, through the chamber 104 has been broken or has been established as may occur when the release mechanism 220 is manipulated, e.g., removed.
At block 306, based on a determination that the release mechanism 220 has been manipulated, the controller 126 may activate the actuator 124 to manipulate the valve mechanism 110 of the toner refill apparatus 100 to cause toner 102 in the toner refill apparatus 100 to flow into the toner cartridge 212.
According to examples, the electronic chip 112 on the chamber 104 may have stored thereon data pertaining to the toner refill apparatus 100. The data pertaining to the apparatus 100 may include identification information of the apparatus 100 and/or toner 102 housed in the chamber 104 of the toner refill apparatus 100. In these examples, the controller 126 may access the data pertaining to the toner refill apparatus 100 from the electronic chip 112 via the electrical circuit component 122. In addition, the controller 126 may determine whether the toner refill apparatus 100 is authenticated based on the accessed data. That is, the controller 126 may determine whether the accessed data corresponds to and/or matches known data of a toner refill apparatus 100 that may be implemented to supply refill toner to the toner cartridge 212. The controller 126 may also or alternatively compare the accessed data, e.g., color, type, and/or the like, of the toner 102 to verify that the toner refill apparatus 100 houses an appropriate type and/or color of toner 102 to be supplied into the toner cartridge 212.
The controller 126 may further, based on a determination that the toner refill apparatus 100 is authenticated, determine that the actuator 124 is to be activated. The controller 126 may still further, based on a determination that the actuator 124 is to be activated, activate the actuator 124 to open the valve mechanism 110 to cause toner 102 in the toner refill apparatus 100 to flow into the toner cartridge 212.
Some or all of the operations set forth in the method 300 may be included as utilities, programs, or subprograms, in any desired computer accessible medium. In addition, the method 300 may be embodied by computer programs, which may exist in a variety of forms both active and inactive. For example, they may exist as machine readable instructions, including source code, object code, executable code or other formats. Any of the above may be embodied on a non-transitory computer readable storage medium.
Examples of non-transitory computer readable storage media include computer system RAM, ROM, EPROM, EEPROM, and magnetic or optical disks or tapes. It is therefore to be understood that any electronic device capable of executing the above-described functions may perform those functions enumerated above.
