Abstract
Abstract A printer/copier apparatus is adapted to receive a replacement ink cartridge (60) that is employed during the printing/copying operation. The apparatus includes a receptacle (66) with a first connector (70) that is coupled to a processor (86) which controls operation of the apparatus. The cartridge (60) includes a second connector (76) which mates with the first connector (70) and a serial access memory (40) that is connected to the second connector (76). Data transfers are enabled both from and to the memory (40) to enable access and modification of data stored therein that is indicative of cartridge usage, calibration, and to parameters for controlling operation of the apparatus. The invention is applicable to replaceable apparatus used with laser and ink jet printers, copiers, etc.

An apparatus for making marks on media sheets, which apparatus is adapted to receive replaceable parts that are subject to wear or include a consumable that is employed during operation of said apparatus, said apparatus including processor means (86) for controlling said apparatus, a receptacle (66) for receiving a replaceable part (60) and first connector means (70) associated with said one receptacle (66) and coupled to said processor means (86), said replaceable part (60) comprising: a second connector means (76) that mates with said first connector means (70); and a serial access memory (40) that is connected to said second connector means (76) by a single data input/output wire (42), said serial access memory (42) storing data at least indicative of usage of said replaceable part (60), said processor means (86) enabled thereby to both read and write data from and to said serial access memory (40).
Claim 2
Dependent Claim
50 words
An apparatus according to claim 1, wherein said serial access memory (40) further stores calibration data for said apparatus, said processor means (86) 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 3
Dependent Claim
58 words
An apparatus according to claim 1, wherein said serial access memory (40) stores a serial number indicative of said replaceable part (60), said processor means (86) including stored data which enables identification of said replaceable part (60) upon a reading of said serial number from said serial access memory (40) and a comparison thereof with said stored data.
Claim 4
Dependent Claim
64 words
An apparatus according to 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 (86) 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 5
Dependent Claim
59 words
An apparatus according to 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 (86) employing said parameter to modify a setting of a further instrumentality in said apparatus to compensate for said charge-to-mass ratio parameter.
