Abstract

In a maintenance management system in which communications control devices of electronic photocopiers are connected through public telephone lines or the like with a host computer of a maintenance company that manages the photocopiers, preventive-maintenance-oriented, omission-free instructions for maintenance work are obtained by determining items of work to be performed based on how many times maintenance has been performed or based on a count of copies produced. For example, in the case where maintenance work to be performed on a first occasion includes items of work belonging to a work item setting area of a second order of precedence within a maintenance table, if items of work that need to be performed do not agree with those specified in the table, items of work of a first order of precedence are added. To achieve this, based on a count at a moment, a work item setting area in the maintenance table is judged to determine its array number, a maintenance state flag is judged, and the array number is incremented by one, so that instructions of the second order of precedence are indicated. Then, the array number of the area is decremented by one, and the flag is judged to be OFF, so that items of work of first order are added to those of the second order. Next, duplicated items within the same area are deleted, whether replacement is necessary or not is judged, and then it is determined that maintenance on the next occasion includes items of work of the first and second orders of precedence.

Claims

1. A maintenance management system for image forming equipment for managing items of maintenance work to be performed for each component of the image forming equipment, comprising:

a work item storing means for setting items of maintenance work that need to be performed for each component regularly at every predetermined count of use of the image forming equipment, and for storing different work item setting areas in order of precedence of regular maintenance occasions;

a work item judging means for judging, based on an order of precedence of a work item setting area referred to at a particular moment, to which work item setting area belongs an item of work to be performed on a next occasion; and

a work item determining means for determining, based on how many times maintenance has been performed for the image forming equipment until a particular moment, whether or not an item of work that belongs to a work item setting area having an order of precedence prior to a result given by said work item judgment means needs to be added to an item of work to be performed on a next occasion.

2. A maintenance management system for image forming equipment as claimed in claim 1,

wherein, when said work item judging means judges that a component needs to be replaced, the work item determining means determines that only replacement of the component be performed.

3. A maintenance management system for image forming equipment as claimed in claim 1,

wherein said work item setting areas in said work item storing means are provided in such a way that a work item to be performed at a particular moment is stored in anticipation, in order to make it possible to perform preventive maintenance.

4. A maintenance management system for image forming equipment as claimed in claim 1,

wherein a main body of the maintenance management system is constructed as a software program running on a host computer which is connected through a communications network to communications control devices that output management data concerning the image forming equipment and which collectively manages said management data.
