Embodiments of the present invention will be described below in detail with reference to the drawings.

FIG. 1 is a schematic diagram showing the configuration of a printer device according to a first embodiment of the present invention. Reference numeral 1 denotes a printer unit that records an image on a recording sheet and discharges it to the outside; Is a sorter bin for stacking the recording paper P discharged from the printer unit 1, and 4 is an interrupt bin for stacking the recording paper P 'discharged from the printer unit 1 in the same manner as the sorter bin 3. Show.

FIG. 2 is a flowchart showing the operation control of the printer of FIG.

When there is a job request from a host computer (not shown) (S1), image data is received from the host computer (S4). At this time, the image deterioration flag and the image deterioration history flag are cleared (S2) and (S3). The received image data is expanded in the frame memory (S5). If the image data can be expanded in the frame memory without running out of memory (No in S6), the printer unit 1 is started (S9). If a memory shortage occurs in the expansion of the image data (Yes in S6), predetermined image deterioration processing (S7), for example, irreversible compression such as thinning is performed, an image deterioration flag is set, and the printer unit 1 starts from (S8).
Is started (S9).

When the printer unit 1 is started (S9), it is determined whether or not the sorter bin 3 is installed in the printer main body (S10) prior to the printing operation (S19). If not installed (No in S10), the printing operation is performed as it is (S1
9). If it is installed (Yes in S10), first, the image deterioration flag is checked (S11) .If the image deterioration flag is not set (No in S12), it is determined that the image deterioration processing has not been performed and the discharge destination is set to the sorter bin. After the designation of No. 3 (S13), the printing operation is performed (S19). If the image deterioration flag is set (Yes in S12),
Judge that the image deterioration processing has been performed, and then check whether or not the number of copies of the page has been specified for multiple copies
(S14). If multiple copies are specified, set the number of copies to 1 (S15),
Unless multiple copies are specified, leave them as they are. Further, the paper discharge destination is designated to the interrupt bin 4 (S16), the image deterioration history flag is set (S17), and the image deterioration flag is cleared (S18), and then the printing operation is performed (S19).

After the printing operation (S19) is completed, it is checked whether or not the print job has been completed (S20). If the print job has not been completed (No in S20), the data of the next page is received
(S4) is performed. If the print job has been completed (Yes in S20),
It is checked whether staples are specified (S21).
If the staple has not been specified (No in S21), the job is terminated (S24). If staples are specified (Y in S21
es), check if the image deterioration history flag is set
(S22). If standing, the job is terminated (S24). If not, the stapling is executed (S23) and the job is terminated (S24).

FIG. 3 is a schematic diagram showing the configuration of a printer device according to a second embodiment of the present invention. Reference numeral 10 denotes a printer unit that records an image on a recording sheet and discharges the image to the outside; And 12 denotes a paper discharge bin on which recording paper discharged from the printer unit 10 is stacked.

The paper discharge bin 12 has a doggy-til function. As shown in FIG. 4, the paper discharge bin 12 is moved in the paper discharge direction (X in the figure).
The stacking position of the recording paper can be changed by moving the recording paper in a direction perpendicular to the direction (Y direction in the figure).
In FIG. 4, reference numeral 13 denotes a discharge port for recording paper in the printer unit 10.

FIG. 5 is a flowchart showing the operation control of the printer of FIG.

The operation control of the second embodiment is obtained by changing the control of step 13 (S13) and step 16 (S16) in the operation control of the first embodiment shown in FIG. That is, Step 13 is a control (S13 ') for designating the paper discharge position as the standard position, and Step 16 is a control (S16') for designating the paper discharge position other than the standard position.

With such a configuration, as shown in FIG. 1 or FIG. 4, the recording paper P 'on which pages whose images have deteriorated due to memory overflow is separated from the recording paper P on which pages which have not deteriorated is printed. The user can clearly recognize that there is a page in which image degradation has occurred because the image can be discharged. Also, if the pages with image deterioration and the pages without image deterioration are discharged separately,
Although a missing page is generated when the stapling operation is performed, according to the present embodiment, if there is a page where image deterioration has occurred, control is performed so that the stapling operation is not performed even if the stapling is specified. The stapling operation is not performed when there are missing pages. Further, when a plurality of copies are designated, a plurality of pages with image deterioration are ejected to the interrupt bin or the output bin. However, if there is a page with image deterioration, the number of copies is reduced to one. Because of the change, only one sheet is output to the discharge bin, and no extra output is made.

Although the embodiment of the present invention has been described by taking an example of image degradation as a result of using compression, the present invention can be applied to all image degradation factors regardless of the compression method or compression.

[0020]

According to the present invention configured as described above, recording paper on which pages with image degradation have been printed and recording paper on which pages without image degradation have been printed can be discharged separately. Because of this, the user can clearly recognize that there is a page where image degradation has occurred.
