Abstract

Print picture quality of an image processing apparatus is diagnosed, thereby enabling whether it is necessary to perform maintenance of the image processing apparatus or not to be monitored even from a remote location. For this purpose, a system for diagnosing the print picture quality of the image processing apparatus has: transfer means for transferring test data which is necessary for a test print from a server to the image processing apparatus; image input means for scanning an image which was print-outputted by the image processing apparatus in accordance with the test data and inputting image data; discriminating means for examining the image data and discriminating the print picture quality of the image processing apparatus; and notifying means for controlling whether the server is notified of the discrimination result in the discriminating means or not in accordance with this discrimination result.

Claims

1. A diagnosing method of diagnosing print picture quality of an image processing apparatus, comprising:

a transfer step of transferring test data which is necessary for a test print from an external apparatus to said image processing apparatus;

an image input step of scanning an image which was print-outputted by said image processing apparatus in accordance with the test data and inputting image data;

a discriminating step of examining the image data and discriminating the print picture quality of the image processing apparatus; and

a notifying step of controlling whether the external apparatus is notified of a discrimination result in said discriminating step or not in accordance with said discrimination result.

2. A method according to claim 1, wherein in said notifying step, whether the external apparatus is notified of the discrimination result or not is discriminated in accordance with contents of a contract of maintenance.

3. A method according to claim 1, wherein in said notifying step,

if the discrimination result is at a predetermined level, the external apparatus is notified of said discrimination result, and

if the discrimination result is not at the predetermined level, said discrimination result is stored and the external apparatus is notified of a plurality of discrimination results in the lump.

4. A method according to claim 1, wherein in said transfer step, said test data is transferred in accordance with a depression of a button showing an instruction of the diagnosis.

5. A method according to claim 1, further comprising:

a use discriminating step of discriminating whether the test data in the external apparatus is used or the test data in said image processing apparatus is used; and

an execution instructing step of issuing an instruction to use the test data in said image processing apparatus to the image processing apparatus on the basis of a result of the discrimination in said use discriminating step.

6. A method according to claim 1, further comprising:

a first counting step of counting the number of print sheets or the number of printing times;

a second counting step of counting the number of print sheets or the number of printing times; and

a count switching step of switching from said first counting step to said second counting step in accordance with that the discrimination result in said discriminating step is at a predetermined level, thereby allowing the number of print sheets or the number of printing times of the image processing apparatus to be counted.

7. A method according to claim 1, further comprising:

a holding step of holding the discrimination result in said discriminating step; and

a history displaying step of displaying a history of the discrimination results held by said holding step.

8. A method according to claim 7, wherein in said history displaying step, at least one of a number issued for the discrimination, date/time when the discrimination has been performed, the discrimination result, and the presence or absence of the notification to the external apparatus is displayed.

9. A method according to claim 1, further comprising a message displaying step of displaying a message showing that the test data has been received in accordance with that the test data is transferred from the external apparatus.

10. A method according to claim 1, further comprising a message displaying step of displaying a message showing that paper is set into said image input step in accordance with a completion of the printing according to the test data.

11. A system for diagnosing print picture quality of an image processing apparatus, comprising:

transfer means for transferring test data which is necessary for a test print from an external apparatus to said image processing apparatus;

image input means for scanning an image which was print-outputted by said image processing apparatus in accordance with the test data and inputting image data;

discriminating means for examining the image data and discriminating the print picture quality of the image processing apparatus; and

notifying means for controlling whether the external apparatus is notified of a discrimination result in said discriminating means or not in accordance with said discrimination result.

12. An image processing apparatus for diagnosing print picture quality of a printer unit, comprising:

receiving means for receiving test data necessary for a test print from an external apparatus;

image input means for scanning an image which was print-outputted by said printer unit in accordance with the test data and inputting image data;

discriminating means for examining the image data and discriminating the print picture quality of the printer unit; and

notifying means for controlling whether the external apparatus is notified of a discrimination result in said discriminating means or not in accordance with said discrimination result.

13. A method of switching counters for counting the number of print sheets or the number of printing times in an image processing apparatus, comprising:

a discriminating step of discriminating a status of said image processing apparatus; and

a count switching step of switching from a first counter to a second counter on the basis of a discrimination result in said discriminating step, thereby allowing the number of print sheets or the number of printing times in the image processing apparatus to be counted.

14. A method according to claim 13, wherein

in said discriminating step, print picture quality in said image processing apparatus is discriminated, and

in said count switching step, said first counter is switched to said second counter in accordance with that the print picture quality is equal to or less than a predetermined level.

15. An image processing apparatus having counters for counting the number of print sheets or the number of printing times, comprising:

discriminating means for discriminating a status of said image processing apparatus; and

count switching means for switching from a first counter to a second counter on the basis of a discrimination result in said discriminating means, thereby allowing the number of print sheets or the number of printing times in the image processing apparatus to be counted.

16. An apparatus according to claim 15, wherein

said discriminating means discriminates print picture quality in said image processing apparatus, and

said count switching means switches said first counter to said second counter in accordance with that the print picture quality is equal to or less than a predetermined level.
