Abstract
When there occurs one of a copy JOB, a printer JOB, and a facsimile JOB, the above JOB is classified into four types and registered into one of a copy JOB queue section 73a, a saved JOB queue section 73b, a priority JOB queue section 73c, and an ordinal JOB queue section 73d. When printing of a print section is completed, whether or not a JOB is registered in any queue section is judged and repeatedly monitored in the order of the queue sections 73a, 73b, 73c, and 73d. When a JOB registered is confirmed, the confirmed JOB is promptly executed.
Claims20
An image forming apparatus executing a plurality of JOBs comprising:
- a document stand which puts a document thereon;
- a reading section for a copy mode which optically reads an image of the document put on the document stand;
- an input section for a printer mode which enters an image transferred from an external device;
- a plurality of paper holding sections where paper is respectively accommodated in different sizes;
- a print section which prints the image read by the reading section and the image entered by the input section on the paper of the respective paper holding sections;
- an operational section which specifies the size of the paper;
- first, second, third, and fourth registers;
- a first judgment section which checks whether or not the proper sized paper for the JOB exists in the paper holding sections when there occurs a copy JOB for printing the image read by the reading section on the paper of the size specified by the operational section, or a printer JOB for printing the image entered by the input section on the paper of the size specified by the external device;
- a second judgment section which checks whether or not the JOB judged in the first judgment section is the above copy JOB when the judgment result of the first judgment section is positive;
- a first control section which registers the above copy JOB into the first register when the judgment result of the second judgment section is positive;
- a second control section which registers the JOB judged in the first judgment section into the second register as a saved JOB when the judgment result of the first judgment section is negative;
- a third judgment section which checks whether or not the number of copies for the JOB judged in the second judgment section is less than a predetermined reference number when the judgment result of the second judgment section is negative;
- a third control section which registers the JOB judged in the third judgment section into the third register as a priority JOB when the judgment result of the third judgment section is positive;
- a fourth control section which registers the JOB judged in the third judgment section into the fourth register as an ordinal JOB when the judgment result of the third judgment section is negative;
- a monitor section which continually monitors whether or not a JOB is registered in the respective registers in the order of the first, the second, the third, and the fourth registers when printing of the print section is completed;
- and
- a fifth control section which executes the registered JOB at once when a JOB registered is found in the above monitor section.

- third control means for registering the JOB judged in the third judgment means into the third register as a priority JOB when the judgment result of the third judgment means is positive;
- fourth control means for registering the JOB judged in the third judgment means into the fourth register as an ordinal JOB when the judgment result of the third judgment means is negative;
- monitor means for repeatedly monitoring whether or not a JOB is registered in the respective registers in the order of the first, the second, the third, and the fourth registers when printing of the print section is completed;
- and
- a fifth control section for executing the registered JOB at once when a JOB registered is found in the above monitor section.

A method of controlling the image forming apparatus executing a plurality of JOBs having
- a document stand for putting a document thereon;
- a reading section for a copy mode for optically reading an image of the document put on the document stand;
- an input section for printer mode for entering an image transferred from an external device;
- a plurality of paper holding sections where paper is respectively accommodated in different sizes;

- operational means for specifying the size of the paper in the respective paper holding means;
- and
- a first, a second, a third, and a fourth registers, the method comprising:
- a first step for checking whether or not the proper sized paper for the JOB exists in the paper holding sections when there occurs a copy JOB for printing the image read by the reading section on the paper of the size specified by the operational means or a printer JOB for printing the image received by the input section on the paper of the size specified by the external device;
- a second step for checking whether or not the JOB judged in the first step is the copy JOB when the judgment result of the first step is positive;
- a third step for registering the copy JOB in the first register when the judgment result of the second step is positive;
- a fourth step for registering the JOB judged in the first step into the second register as a saved JOB when the judgment result of the first step is negative;

- a sixth step for registering the JOB judged in the fifth step into the third register as a priority JOB when the judgment result of the fifth step is positive;
- a seventh step for registering the JOB judged in the fifth step into the fourth register as an ordinal JOB when the judgment result of the fifth step is negative;
- an eighth step for continually monitoring whether or not a JOB is registered in the respective registers in the order of the first, the second, the third, and the fourth registers when printing of the print section is completed;
- and
- a ninth step for executing the registered JOB at once when a JOB registered is found in the eighth step.
