Abstract

Abstract A reprographic apparatus such as a copier or printer is controlled by a controller including a microprocessor and a memory, the apparatus including one or more sheet trays for supplying sheets which will receive images in use of the apparatus. One or more operating parameters of the apparatus, such as the timing of sheet feeding devices, or fuser temperature, are selectively variable in accordance with differing characteristics of sheets to be used. A set of values of the operating parameters are held in the memory for each kind of sheet, and the appropriate operating parameters are set to the values derived from the memory for a given sheet type. The sheet type, and hence the operating parameters, may be set by a local or remote user of the apparatus. Alternatively, the apparatus may include means associated with at least one of the trays for recognising sheet characteristics and setting the operating parameters accordingly.

Claims Analysis

Total Claims: 7
Claim 1
Independent Claim 104 words
Reprographic apparatus controlled by a controller including a microprocessor and a memory, the apparatus including one or more sheet trays for supplying sheets which will receive images in use of the apparatus, wherein one or more operating parameters of the apparatus are selectively variable in accordance with differing characteristics of sheets to be used, characterised in that a set of values of the operating parameters are held in the memory for each of a series of different kinds of sheet, and that means are provided for setting the appropriate operating parameters to the values derived from the memory in accordance with the sheet characteristics.
Claim 2
Dependent Claim 20 words
The apparatus of claim 1 wherein the setting means is operable by a local or remote user of the apparatus.
Claim 3
Dependent Claim 30 words
The apparatus of claim 1 including means associated with at least one of the trays for recognising sheet characteristics and for operating the setting means to set the operating parameters.
Claim 4
Dependent Claim 44 words
The apparatus of claim 3 wherein sheets of specified characteristics are contained within a cassette, the cassette having identification means corresponding to the sheet characteristics, and the tray including means responsive to the identification means for setting the operating parameters on receiving the cassette.
Claim 5
Independent Claim 36 words
The apparatus of any one of claims 1 to 3 wherein the memory is a non-volatile memory which stores information including operating parameters in the form of apparatus settings, performance and service data and diagnostic information.
Claim 6
Independent Claim 43 words
The apparatus of any one of claims 1 to 5 wherein one of the operating parameters is the time of starting to form a buckle in each of the copy sheets just prior to transfer of a developed image to each copy sheet.
Claim 7
Independent Claim 22 words
The apparatus of any one of claims 1 to 5 wherein one of the operating parameters is the temperature of the fuser.
