Toner cartridge having a movable projection for providing installation feedback to an image forming device
A toner cartridge according to one example embodiment includes a housing having a toner reservoir. An outlet port faces downward on a front of the housing near a first side of the housing. A shutter is movable between a closed position blocking the outlet port and an open position unblocking the outlet port. A flag on the first side of the housing is movable between a first position and a second position. The flag extends outward sideways from the first side when the flag is in the second position. The flag is operatively connected to the shutter such that when the shutter moves from the closed position to the open position the flag moves from the first position to the second position to change a state of a sensor in the image forming device when the toner cartridge is installed in the image forming device.
1. A toner cartridge for use in an image forming device, comprising:
a housing having a top, a bottom, a front, and a rear positioned between a first side and a second side of the housing, the housing has a reservoir for holding toner;
an outlet port in fluid communication with the reservoir and facing downward on the front of the housing near the first side of the housing for exiting toner from the toner cartridge;
a shutter movable between a closed position blocking the outlet port and an open position unblocking the outlet port; and
a flag on the first side of the housing, the flag is movable between a first position and a second position, the flag extends outward sideways from the first side when the flag is in the second position, the flag is operatively connected to the shutter such that when the shutter moves from the closed position to the open position the flag moves from the first position to the second position to change a state of a sensor in the image forming device when the toner cartridge is installed in the image forming device.
2. The toner cartridge of claim 1 , wherein the flag is biased toward the first position.
3. The toner cartridge of claim 1 , wherein the flag moves upward as the flag moves from the first position to the second position.
4. The toner cartridge of claim 3 , further comprising an alignment guide that extends outward sideways on the first side of the housing, wherein in the second position a top portion of the flag is positioned higher than at least a portion of a top surface of the alignment guide.
5. The toner cartridge of claim 3 , further comprising an alignment guide that extends outward sideways on the first side of the housing, wherein in the first position the flag extends outward sideways from the first side and is in line with the alignment guide from the rear to the front of the housing.
6. The toner cartridge of claim 5 , wherein the alignment guide runs from the rear to the front of the housing on the first side of the housing.
7. The toner cartridge of claim 6 , wherein the alignment guide includes a shield positioned in front of the flag when the flag is in the first position.
8. The toner cartridge of claim 3 , further comprising:
a channel running along the front of the housing between the first side and the second side in fluid communication with the outlet port, at least a portion of the channel is open to the reservoir; and
an auger positioned in the channel and extending along the front of the housing between the first side and the second side, the auger is operative to move toner in the channel toward the outlet port,
wherein in the second position a top portion of the flag is positioned higher than a bottom surface of the channel.
9. The toner cartridge of claim 3 , further comprising:
a channel running along the front of the housing between the first side and the second side in fluid communication with the outlet port, at least a portion of the channel is open to the reservoir; and
an auger positioned in the channel and extending along the front of the housing between the first side and the second side, the auger is operative to move toner in the channel toward the outlet port,
wherein in the second position a top portion of the flag is positioned in line with the channel from the second side to the first side of the housing.
10. The toner cartridge of claim 3 , further comprising:
a channel running along the front of the housing between the first side and the second side in fluid communication with the outlet port, at least a portion of the channel is open to the reservoir;
an auger positioned in the channel and extending along the front of the housing between the first side and the second side, the auger is operative to move toner in the channel toward the outlet port; and
a toner delivery assembly positioned in the reservoir to deliver toner to the channel, the toner delivery assembly includes a drive shaft rotatably mounted in the reservoir, the drive shaft includes a rotational axis,
wherein in the second position a top portion of the flag is positioned higher than the rotational axis of the drive shaft.
11. The toner cartridge of claim 1 , wherein the flag moves outward sideways from the first side as the flag moves from the first position to the second position.
12. The toner cartridge of claim 1 , further comprising a linkage on the first side of the housing, the linkage has an engagement surface that is accessible at the rear of the housing to receive an actuation force at the rear of the housing, the linkage is movable forward toward the front of the housing upon the engagement surface receiving the actuation force at the rear of the housing, wherein the shutter is operatively connected to the linkage such that forward movement of the linkage causes the shutter to move from the closed position to the open position.
13. The toner cartridge of claim 12 , wherein the linkage is biased rearward toward the rear of the housing.
