Abstract
It is an object of the present invention to provide an apparatus and method which allow a service engineer to accurately analyze the situation of a printer and specify a failure when he or she arrives at the place where the printer is installed. A computer predicts a failure from the status information of a printer, and transmits a test pattern corresponding to the failure to the printer via a controller. The computer then outputs an indication of print out. The service engineer can accurately analyze the failure because the test pattern has already been printed out upon occurrence of the failure.
Claims16
A method of printing a test pattern, comprising the steps of:
- determining a type of abnormality in a printer on the basis of status information of said printer;
- and
- causing said printer to print out a test pattern corresponding to the determined type of abnormality.
An apparatus for outputting a test pattern, comprising:
- determining means for determining a type of abnormality in a printer on the basis of status information of said printer;
- and
- transmission means for transmitting a test pattern corresponding to the type of abnormality determined by said determining means to said printer and causing said printer to print out the test pattern.
A method of printing a test pattern, comprising the steps of:
- determining a type of abnormality in an image forming apparatus on the basis of status information of the image forming apparatus;
- and
- causing the image forming apparatus to form a test pattern corresponding to the determined type of abnormality.
An apparatus for outputting a test pattern, comprising:
- determining means for determining a type of abnormality in an image forming apparatus on the basis of status information of the image forming apparatus;
- and
- transmission means for transmitting a test pattern corresponding to the determined type of abnormality determined by said determining means to the image forming apparatus and causing the image forming apparatus to form the test pattern as an image.
