Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
152 words
Apparatus for making marks on media sheets, said apparatus adapted to receive replaceable parts that are subject to wear or include a consumable that is employed during operation of said apparatus, said apparatus comprising: processor means (28) for controlling said apparatus; a receptacle (36) for receiving a replaceable part; first connector means (52) associated with said one receptacle and coupled to said processor means (28); and a replaceable part (50), juxtaposed to said receptacle (36) and including a second connector means (30) that mates with said first connector means (52), said replaceable part (50) including a serial access memory (40) that is connected to said second connector means (30) by only a single wire (42), said processor means (28) enabled thereby to both read and write data from and to said serial access memory (40), said serial access memory (40) storing data at least indicative of usage of said replaceable part (50).
Claim 2
Dependent Claim
37 words
The apparatus as recited in claim 1 wherein said processor means (28) is controlled to periodically write updated usage data into said serial access memory (40) so as to accurately reflect usage of said replaceable part (50).
Claim 3
Dependent Claim
53 words
The apparatus as recited in claim 1 wherein said serial access memory (40) further stores calibration data for said replaceable part (50), said processor means (28) controlled to access said calibration data and to combine said calibration data with other data so as to enable the generation of control signals for said apparatus.
Claim 4
Dependent Claim
59 words
The apparatus as recited in claim 1, wherein said serial access memory (40) stores a serial number indicative of said replaceable part (50), said processor means (28) including stored data which enables identification of said replaceable part (50) upon a reading of said serial number from said serial access memory (40) and a comparison thereof with said stored data.
Claim 5
Dependent Claim
65 words
The apparatus as recited in claim 1, wherein said serial access memory (40) is coupled to a fuser assembly and includes data regarding past usage history of an incorporated silicone oil supply, said processor means (28) responding to said data regarding past usage history to modify a temperature of said fuser assembly upon determining that a transparency media sheet is to pass in contact therewith.
Claim 6
Dependent Claim
60 words
The apparatus as recited in claim 1, wherein said serial access memory (40) is coupled to a developer module and stores a parameter defining a charge-to-mass ratio of toner carrier contained within said developer module, said processing means (28) employing said parameter to modify a setting of a further instrumentality in said apparatus to compensate for said charge-to-mass ratio parameter.
Claim 7
Dependent Claim
60 words
The apparatus as recited in claim 1, wherein said serial access memory (40) is coupled to a developer module and stores parameters defining a developer magnet strength and a distance between a surface of said developer module and a photoconducting drum, said processing means (28) employing said parameters to enable adjustment of further parameters within said apparatus to compensate therefor.
