Abstract

An image processing device includes an acquiring section, a determining section, a storage section, and a reacquiring section. The acquiring section is configured to acquire data based on reference information indicative of a reference location on a network. The determining section is configured to determine whether the acquiring section succeeds or fails in acquisition of the data. The storage section is configured to store the reference information when the determining section determines that the acquiring section fails in acquisition of the data. The reacquiring section is configured to reacquire data based on the reference information stored in the storage section.

Claims

1. An image processing device comprising:

an image forming section configured to form an image on a sheet;

a processor;

a network interface connectable to a network;

a receiving unit;

a first memory;

a second memory separate from the first memory; and

a third memory storing instructions, the instructions, when executed by the processor, causing the processor to perform;

receiving reference information indicative of a reference location on the network by the receiving unit;

storing the reference information received by the receiving unit in the first memory;

acquiring data and a status code through the network interface based on the reference information stored in the first memory;

after acquiring the status code, determining whether the acquired status code is a first status code that is obtained when acquisition of the data is performed normally;

when it is determined that the acquired status code is the first status code, controlling the image forming section to form an image based on the acquired data on a sheet;

when it is determined that the acquired status code is other than the first status code, storing the reference information in the second memory;

after storing the reference information in the second memory, determining whether the acquired status code is a second status code that indicates a temporary error;

when it is determined that the acquired status code is the second status code, reacquiring the data based on the reference information in the second memory in a first period; and

when it is determined that the acquired status code is other than the second status code, reacquiring the data based on the reference information in the second memory in a second period, the second period being longer than the first period.

2. The image processing device according to claim 1, wherein, when executed by the processor, the instructions further cause the processor to perform:

determining a reason why acquisition of the data fails; and

setting a method in which the data are reacquired based on the reason;

wherein the instructions for reacquiring data comprise reacquiring the data with the method.

3. The image processing device according to claim 2, wherein, when executed by the processor, the instructions further cause the processor to perform:

receiving a status code; and

determining whether the received status code matches a predetermined status code;

wherein the instructions for determining a reason comprise, when the received status code matches the predetermined status code, determining that an error corresponding to the status code is the reason why acquisition of the data fails.

4. The image processing device according to claim 3, wherein the instructions for setting a method comprise, when the received status code matches a status code including other reference information, setting the method in such a manner that data corresponding to the other reference information are reacquired.

5. The image processing device according to claim 4, wherein the instructions for setting a method comprise setting the method in such a manner that the data corresponding to the other reference information are reacquired instantaneously.

6. The image processing device according to claim 2, further comprising a timer configured to measure time,

wherein the instructions for determining a reason comprise determining that the reason of failure is shortness of time when the time measured by the timer is longer than or equal to a predetermined period.

7. The image processing device according to claim 3, wherein the instructions further cause the processor to perform:

determining that the reason of failure is shortness of time when the received status code is a status code indicative of timeout.

8. The image processing device according to claim 1, wherein, when executed by the processor, the instructions further cause the processor to perform:

detecting a transmission speed of acquiring the data; and

determining whether the detected transmission speed is higher than or equal to a predetermined transmission speed; and

wherein the instructions for reacquiring data comprise reacquiring the data when the detected transmission speed is higher than or equal to the predetermined transmission speed.

9. The image processing device according to claim 8, wherein, when executed by the processor, the instructions further cause the processor to perform:

transmitting a request packet to the reference location, to measure a response period from timing at which the request packet is transmitted to the reference location to timing at which the request packet is returned; and

detecting the transmission speed based on a data amount of the request packet and on the response period.

10. The image processing device according to claim 1, further comprising an image forming section configured to print either the data acquired in the instructions for acquiring data or the data reacquired in the instructions for reacquiring data.

11. The image processing device according to claim 1, wherein the reference information is inputted via an input screen for prompting a user to input the reference information.

12. The image processing device according to claim 1, wherein the first status code is any one of “

200;

OK” and

“

206;

Partial Content”

; and

wherein the second status code is “

503;

Service Unavailable”

.

13. An image processing system comprising:

an image processing apparatus; and

a web server configured to send data and a status code to the image processing apparatus in response to receiving a request for acquiring the data and the status code,

wherein the image processing apparatus comprises;

an image forming section configured to form an image on a sheet;

a processor;

a network interface connectable to a network;

a receiving unit;

a first memory;

a second memory separate from the first memory; and

a third memory storing instructions, the instructions, when executed by the processor, causing the processor to perform;

receiving a reference information indicative of a reference location of the web server on the network by the receiving unit;

storing the reference information received by the receiving unit in the first memory;

acquiring data and a status code from the web server through the network interface based on the reference information stored in the first memory;

after acquiring the status code, determining whether the acquired status code is a first status code that is obtained when acquisition of the data is performed normally;

when it is determined that the acquired status code is the first status code, controlling the image forming section to form an image based on the acquired data on a sheet;

when it is determined that the acquired status code is other than the first status code, storing the reference information in the second memory;

after storing the reference information in the second memory, determining whether the acquired status code is a second status code that indicates a temporary error;

when it is determined that the acquired status code is the second status code, reacquiring the data from the web server based on the reference information in the second memory in a first period; and

when it is determined that the acquired status code is other than the second status code, reacquiring the data from the web server based on the reference information in the second memory in a second period, the second period being longer than the first period.

14. The image processing system according to claim 13, wherein the first status code is any one of “

200;

OK” and

“

206;

Partial Content”

; and

wherein the second status code is “

503;

Service Unavailable”
