Abstract

An image processing apparatus includes circuitry configured to provide information in response to satisfaction of a given condition. The information indicates that a mixed-color characteristic is to be corrected.

First claim

What is claimed is:

1. An image processing apparatus comprising:
an operation panel that includes a panel display; and
circuitry configured to
determine whether a condition is satisfied, the condition including whether the number of drive instructions received by at least one of a pressure roller or a heating roller exceeds a predetermined threshold number,
provide information in response to satisfaction of the condition, the information indicating that a mixed-color characteristic is to be corrected and being displayed as a message on the panel display prompting correction of the mixed-color characteristic, and
determine whether an instruction to correct the color mixed-color characteristic has been received in response to the message, wherein
in a case where the instruction to correct the mixed-color characteristic has not been received, the circuitry repeats the determination of whether the instruction has been received until it is determined that the instruction has been received.

2. The image processing apparatus according to claim 1 , wherein
the condition further includes count information indicating at least one of a number of recording media bearing transferred toner images or a number of recording media bearing fixed toner images, and
the circuitry is further configured to provide the information in a case where at least one of the number of recording media bearing transferred toner images, the number of recording media bearing fixed toner images, or the number of drive instructions received by at least one of a pressure roller or a heating roller exceeds a threshold number.

3. The image processing apparatus according to claim 1 , further comprising:
a transfer device configured to transfer a toner image onto a recording medium; and
a fixing device configured to fix the toner image onto the recording medium, wherein
the condition further includes replacement information indicating a replacement of at least one of the transfer device or the fixing device, and
the information is provided in a case where the replacement information indicates at least one of the transfer device or the fixing device has been replaced.

4. The image processing apparatus according to claim 3 , wherein
the transfer device includes an intermediate transfer belt,
the fixing device includes a fixing belt, and
the information is provided in a case where the replacement information indicates at least one of the intermediate transfer belt or the fixing belt has been replaced.

5. The image processing apparatus according to claim 1 , further comprising:
a container configured to store a recording medium, wherein
the condition further includes container information indicating addition of the recording medium to the container, and
the information is provided in a case where the container information indicates the addition of the recording medium to the container.

6. The image processing apparatus according to claim 1 , wherein
the condition further includes recording medium change information indicating a change to a type of recording medium, and
the information is provided in a case where the recording medium change information indicates the type of recording medium has been changed.

7. The image processing apparatus according to claim 1 , further comprising:
an intermediate transferor, wherein
the condition further includes primary transfer current change information indicating a change to an assigned value of a primary transfer current supplied to the intermediate transferor, the primary transfer current being supplied to transfer a toner image onto the intermediate transferor, and
the information is provided in a case where the primary transfer current change information indicates the assigned value of the primary transfer current supplied to the intermediate transferor has been changed.

8. The image processing apparatus according to claim 1 , wherein
the condition further includes secondary transfer current change information indicating a change to an assigned value of a secondary transfer current that transfers a toner image onto a recording medium, and
the information is provided in a case where the secondary transfer current change information indicates the assigned value of the secondary transfer current has been changed.

9. The image processing apparatus according to claim 1 , further comprising:
a fixing device configured to fix a toner image onto a recording medium, wherein
the condition further includes fixing temperature change information indicating a change to an assigned value of a fixing temperature at which the fixing device fixes the toner image onto the recording medium, and
the information is provided in a case where the fixing temperature change information indicates the assigned value of the fixing temperature has been changed.

10. The image processing apparatus according to claim 1 , wherein the circuitry is configured to terminate a process of providing the information upon determining that the condition is not satisfied.

11. An image processing method comprising:
determine whether a condition is satisfied, the condition including whether number of drive instructions received by at least one of a pressure roller or a heating roller exceeds a predetermined threshold number,
providing information in response to satisfaction of the condition, the information indicating that a mixed-color characteristic is to be corrected;
displaying the provided information as a message on a panel display connected to a computer to prompt for correction of the mixed-color characteristic; and
determining whether an instruction to correct the color mixed-color characteristic has been received in response to the message, wherein
in a case where the instruction to correct the mixed-color characteristic has not been received, the circuitry repeats the determination of whether the instruction has been received until it is determined that the instruction has been received.

12. The image processing method according to claim 11 , wherein
the condition further includes count information indicating at least one of a number of recording media bearing transferred toner images or a number of recording media bearing fixed toner images, and
the information is provided in a case where at least one of the number of recording media bearing transferred toner images, the number of recording media bearing fixed toner images, or the number of drive instructions received by at least one of a pressure roller or a heating roller exceeds a threshold number.

13. The image processing method according to claim 11 , wherein
the condition further includes replacement information indicating a replacement of at least one of a transfer device, device configured to transfer a toner image onto a recording medium, or a fixing device, configured to fix the toner image onto the recording medium, and
the information is provided in a case where the replacement information indicates at least one of the transfer device or the fixing device has been replaced.

14. The image processing method according to claim 13 , wherein
the transfer device includes an intermediate transfer belt,
the fixing device includes a fixing belt, and
the information is provided in a case where the replacement information indicates at least one of the intermediate transfer belt or the fixing belt has been replaced.

15. The image processing method according to claim 11 , wherein
the condition further includes container information indicating addition of a recording medium to a container configured to store the recording medium, and
