Abstract
A host computer 104 at a remote administrative site receives a jam code and the number of accumulated copies made from a photocopier 100 at which jamming has occurred, an accumulated jam curve is calculated based on the received data, a certain filtering process is performed, the risk of jamming is estimated based on the filter output and a membership function between the filter value and risk, thus judging whether or not to visit the user.
Claims45
An administrative device for image forming apparatuses, comprising:
- receiving means for receiving number information regarding the number of sheets recorded on by the image forming apparatus and abnormality information;
- first calculating means for calculating an accumulation curve of abnormalities based on the number information and the abnormality information;
- second calculating means for performing filtering processing to the accumulation curve obtained by said first calculating means, so as to obtain filter output;
- and
- estimating means for estimating the risk of occurrence of abnormalities based on the filter output obtained by said second calculating means.
An administrative device for image forming apparatuses, comprising:
- receiving means for receiving number information regarding the number of sheets recorded on by the image forming apparatus and abnormality information;
- first calculating means for calculating an accumulation curve of abnormalities based on the number information regarding the number of sheets recorded by the image forming apparatus received by said receiving means and abnormality information;
- second calculating means for performing a plurality of filtering processes to the accumulation curve obtained by said first calculating means using a plurality of filters, so as to obtain a plurality of filter outputs;
- estimating means for estimating the individual risk of occurrence of abnormalities for each filter, based on the plurality of filter outputs obtained by said second calculating means;
- and
- third calculating means for weighing the individual risk of occurrence of abnormalities for each of the plurality of filters estimated by said estimating means, so as to obtain risk relating to occurrence of abnormalities.
An administrative method for image forming apparatuses, comprising the steps of:
- a) receiving number information regarding the number of sheets recorded on by the image forming apparatus and abnormality information;
- b) calculating an accumulation curve of abnormalities based on the number information and the abnormality information;
- c) performing filtering processing to the accumulation curve obtained in step (b), so as to obtain filter output;
- and
- d) estimating the risk of occurrence of abnormalities, based on filter output obtained in step (c).
