[0044]
FIG. 2 is a diagram illustrating an example of the tray management information stored in the auxiliary storage device 3 of the image forming apparatus illustrated in FIG.
[0045]
In FIG. 2, the image forming apparatus of this embodiment has four paper feed trays of paper feed tray numbers “1” to “4” and feeds paper feed trays of paper feed tray number “1”. Indicates that recording paper having a paper quality of “plain paper” and a paper size of “A4 landscape” is stored, the presence or absence of paper in this paper feed tray is “present”, and the state is “Ready”, that is, This indicates that the paper is ready.
[0046]
The paper feed tray of paper feed tray number “2” stores recording paper of paper quality “thick paper” and paper size “A4 landscape”, and the presence or absence of paper in this paper feed tray is “Yes”. This state indicates "Not Ready", that is, a paper feeding impossible state.
[0047]
The paper feed tray of paper feed tray number “3” stores recording paper of paper quality “OHP” and paper size “A4 portrait”, and the presence or absence of paper in this paper feed tray is “Yes”. The state indicates “Broken”, that is, a failure state.
[0048]
The paper feed tray with the paper feed tray number “4” stores recording paper having a paper quality of “high quality paper” and a paper size of “A3 landscape”. ", Indicating that the state is" Not Ready ", that is, the sheet cannot be fed.
[0049]
The tray management information shown in FIG. 2 is updated periodically each time the paper set in each paper feed tray is detected.
[0050]
FIG. 3 is a flowchart showing the operation of the image forming apparatus according to this embodiment.
[0051]
In FIG. 3, when a printout instruction is given to the image forming apparatus and the printout process is started (step 400), first, referring to the tray management information shown in FIG. It is determined whether there is a possible paper feed tray, that is, whether or not the paper feed trays of the paper feed tray numbers “1” to “4” can automatically feed paper (step 401).
[0052]
If there is a paper feed tray in which automatic paper feeding is possible (YES in step 402), it is determined whether there is a recording paper tray matching the document size, that is, the automatic paper feeding is possible. It is checked whether there is a paper feed tray in which the recording paper matching the size of the document to be printed out is stored in the paper feed tray in the proper state (step 403).
[0053]
If there is a recording paper tray that matches the document size (YES in step 402), paper is fed from that recording paper tray and printed out. For example, if an A4 landscape document has been received, paper is fed from the paper feed tray number “1” and printed out.
[0054]
Next, it is checked whether the printout instruction is a double-sided print (step 404). If the printout instruction is a double-sided print (YES in step 404), the process proceeds to a double-sided printout process for printing the original of the next page on the back side of the sheet just printed. The process shifts (step 405), and if it is not double-sided printing (NO in step 404), the process shifts to single-sided printout processing for printing the original of the next page on the same side of the next sheet (step 406).
[0055]
By the way, when it is determined in step 401 that there is no tray capable of feeding, that is, when all the feed trays are in the “Not Ready” or “Broken” state (NO in step 401), or In step 402, if there is no recording paper that matches the document size, that is, if there is a paper feed tray in the “Ready” state, but the size of the paper in this paper feed tray is If the size does not match (NO in step 402), a message asking whether paper can be fed from the manual feed tray is displayed (step 407).
[0056]
In this state, the user checks the recording paper in the manual feed tray and determines whether or not to print out from the manual feed tray (OK or not) (step 408). In this determination, if it is determined to be OK (YES in step 408), the flow advances to step 406 to execute a one-sided printout process.
[0057]
If it is determined in step 408 that the printing is not OK (NO in step 408), the printing apparatus enters a print waiting state in which the sheet feeding tray returns to a usable state, and waits until printing can be performed (step 409). For example, when an original of A3 landscape is being received, the tray management information shown in FIG. 2 indicates that the paper feed tray of tray number "4" for storing the recording paper of A3 landscape is in the "Not Ready" state. Therefore, the process waits until the sheet feed tray enters the “Ready” state.
[0058]
In the above-described embodiment, when printing is performed on the recording paper in the manual feed tray, the single-sided printing is always controlled even when the machine setting is the double-sided printing. However, as shown in FIG. Permission / non-permission of double-sided printing is set and stored according to the paper quality, and control may be performed such that single-sided printing is performed only when the paper quality set in the manual feed tray does not permit double-sided printing. .
[0059]
For example, if the paper quality of the manual feed tray is OHP, double-sided printing is prohibited according to the setting in FIG. 4, so single-sided printing is performed even if the machine setting is double-sided printing.
[0060]
FIG. 5 is a flowchart showing the operation of the image forming apparatus in such a configuration.
[0061]
In FIG. 5, when a printout instruction is given to the image forming apparatus and the printout processing is started (step 500), first, referring to the tray management information shown in FIG. It is determined whether there is a possible paper feed tray, that is, whether or not the paper feed trays of the paper feed tray numbers “1” to “4” can automatically feed paper (step 401).
[0062]
If there is a paper feed tray in which automatic paper feeding is possible (YES in step 502), it is determined whether there is a recording paper tray matching the document size, that is, the automatic paper feeding is possible. It is checked whether there is a paper feed tray in which the recording paper matching the size of the document to be printed out is stored in the paper feed tray in the proper state (step 503).
[0063]
If there is a recording paper tray that matches the document size (YES in step 502), paper is fed from that recording paper tray and printed out.
[0064]
Next, it is checked whether the printout instruction is a two-sided print (step 504). If the printout instruction is a two-sided print (YES in step 504), the process proceeds to a two-sided printout process in which the original of the next page is printed on the back side of the currently printed sheet. The process shifts (step 505), and if it is not double-sided printing (NO in step 504), the process shifts to a single-sided printout process of printing the original of the next page on the same side of the next sheet (step 506).
[0065]
If it is determined in step 501 that there is no tray that can supply paper, that is, if all the paper trays are in the “Not Ready” or “Broken” state (NO in step 501), or In step 502, if there is no recording paper that matches the document size, that is, if there is a paper feed tray in the “Ready” state, the size of the recording paper in this paper feed tray is If the size does not match (NO in step 502), a message asking whether paper can be fed from the manual feed tray is displayed (step 507).
[0066]
In this state, the user checks the recording paper in the manual feed tray and determines whether or not to print out from the manual feed tray (OK or not) (step 508). In this determination, if it is determined to be OK (YES in step 508), it is checked whether or not the quality of the recording paper in the manual feed tray can be printed on both sides (step 510).
[0067]
The determination in step 510 is based on the settings shown in FIG. That is, if the paper quality of the recording paper in the manual feed tray is “plain paper” or “fine paper” for which double-sided printing is permitted, it is determined that double-sided printing is possible (YES in step 510), and the process proceeds to step 504. Next, it is checked whether the printout instruction is a double-sided print (step 504). If the printout instruction is a double-sided print (YES in step 504), a double-sided printout for printing the original of the next page on the back side of the sheet that has just been printed is performed. The process shifts to step S505, and if it is not double-sided printing (NO in step S504), the process shifts to single-sided printout processing for printing the original of the next page on the same side of the next sheet (step S506).
[0068]
If the paper quality of the recording paper in the manual feed tray is “thick paper” or “OHP” for which double-sided printing is prohibited, it is determined that double-sided printing is not possible (NO in step 510), and the process proceeds to step 506 to perform single-sided printout processing. Execute
[0069]
If it is determined in step 508 that the printing is not OK (NO in step 508), the printing apparatus enters a print waiting state in which the sheet feeding tray returns to a usable state and printout can be performed (step 509).
[0070]
