Samsung CLP-315W:
The Samsung CLP-315W is a full color laser printer with built-in wireless connectivity that makes it easy to link several computers to the printer over a network. The compact CLP-315 series is one of the smallest in its class and the individual cheap toner cartridges save money by giving you the option of replacing each one separately.
The CLP-315W uses three color and one black cheap toner cartridge. These cheap cartridges are lightweight and easy to remove and replace using the color-coded tabs. Each cheap cartridge only comes in one capacity of 1,000 pages. These cartridges can by cheaply purchased for about $40. Since the black and color cartridges cost the same, we can estimate that each page will cost about 4 cents to print. Samsung is also limited by the number of pages it can print per month. The CLP-315W’s duty cycle number is about 20,000 pages.
Relative to other similarly priced color laser printers, the CLP-315W is significantly slower than the pack in both black and white and especially color prints. It scored 13.15 pages per minute for plain black speed, slightly faster than the Dell 1320c. The CLP-315W also takes the longest to spit out any kind of color document, scoring a measly 3.64 pages per minute for color graphics and 4.07 pages per minute for color text. The rest of the units in the comparison lineup finished printing in less than half the time in both categories.
==================
An ink cartridge, comprising: a cartridge case enclosing an ink chamber; a path extending from the ink chamber to an exterior of the ink cartridge; a valve member provided in the path, the valve member having a first state in which communication between the ink chamber and the exterior of the ink cartridge along the path is permitted and a second state in which communication between the ink chamber and the exterior of the ink cartridge along the path is prevented; and an extraction receiving member comprising an insertion port that forms a portion of the path, the extraction receiving member being capable of receiving a hollow ink extraction member of an inkjet recording device when the ink cartridge is installed in the inkjet recording device; wherein: the insertion port decreases in diameter from an exterior-side surface to a seal portion located between the exterior-side surface and an ink chamber-side surface, the insertion port having a diameter less than a diameter of the ink extraction member at the seal portion; when the extraction receiving member receives the ink extraction member, the valve member is moved from the second state to the first state; the ink chamber-side surface of the extraction receiving member comprises at least one protrusion that contacts an exterior-side surface of the valve member; and the at least one protrusion protrudes from a pedestal surface located between the protrusion and the sealing portion, the pedestal surface being substantially perpendicular to a direction in which the ink extraction member is inserted into the extraction receiving member.
2. The ink cartridge according to claim 1, wherein the protrusion extends along the ink-chamber side surface of the extraction receiving member so as to surround the insertion port.
3. The ink cartridge according to claim 1, wherein at least one portion of the insertion port has step-like shape between the exterior-side surface of the extraction receiving member and the seal portion, such that the at least one portion of the insertion port decreases incrementally in diameter from the exterior-side surface to the seal portion.
