Flashes. If there are multiple failures, 3
The error code is cycled at intervals of seconds.

Then, by pressing the supplement / buzzer cut switch 89 on the display panel 79, the buzzer stops ringing, and after 25 minutes, if the fault has not been cleared, the buzzer rings again.

By eliminating the obstacle, the error code displayed on the 7-segment display section 85 of the display panel 79 is canceled. Error code "E. *"
* ", Error content, error set condition and error reset condition are shown in FIGS.

Unlike the conventional apparatus, this apparatus can shift to the "operation check mode" even while the apparatus is operating. Specifically, when a failure occurs during the operation of the apparatus, the error code “E. **” is displayed on the 7-segment display section 85 of the display panel 79 as described above. Here, the operator shifts to the operation check by changing the dip switch in the apparatus or performing a specific operation on a specific switch on the display panel 79 while the apparatus is operating. Then, the display changeover switch 8
By operating 7, the operation check result of the developing section or the operation check result of the chemical mixer is displayed on the 7-segment display section 85 of the display panel 79.

In this embodiment, depending on the content of the failure,
The display order of the operation check result of the developing section and the operation check result of the chemical mixer is automatically switched. That is, if there is a failure in the chemical mixer unit 2, the operation check result of the chemical mixer is displayed first.

In the present apparatus, the developing temperature LED of the 7-segment display contents LED 86 of the display panel 79 blinks when the "developing section operation check mode" is entered, and when the "developing chemical mixer operation check mode" is entered,
The drying temperature LED of the 7-segment display content LED 86 of the display panel 79 blinks to clarify the difference from the normal mode.

Then, the operation check result shows that when the sensor or output component in the device is ON, the corresponding display panel 79
The segment of the 7-segment display section 85 is turned on. FIG. 16 (a) shows the display contents of each segment of the 7-segment display unit 85 in the operation check mode of the developing unit, and FIG. 16 (b) shows the display contents of each segment of the 7-segment display unit 85 in the operation check mode of the chemical mixer. The display contents are shown below. Especially in the operation check mode of the chemical mixer
By matching the layout of the 7-segment display unit 85 with the layout of the actual sensor and equipment, you can
Operation check is possible.

For example, while the apparatus is operating, the display panel 79
The error code "E.01" or "E.0" appears on the 7-segment display 85.
When "2" is displayed and "Development temperature drop (rise) abnormality" occurs, the operator shifts the device to the operation check mode of the developing unit while the device is operating. Then, the operating states of the DEV heater (2b), the water supply solenoid valve (3a) and the circulation pump (2g) of the 7-segment display section 85 of the display panel 79 are confirmed to identify the abnormal portion.

Also, while the apparatus is operating, the display panel 79
When the error code "E.10" is displayed on the segment display section 85 and "the developer surface is not detected", the operator shifts the apparatus to the operation check mode of the developing section while the apparatus is operating. Then, the operation state of the DEV liquid level detection (2a) and the DEV replenishment pump (3f) on the 7-segment display section 85 of the display panel 79 is confirmed, and the abnormal portion is specified.

Furthermore, during operation of the device, the display panel 79
The error code "E.19" or "E.2" appears on the segment display section 85.
"4" is displayed and "Fusing SW detection error in upper surface of fixing"
In case of, the operator shifts the apparatus to the operation check mode of the chemical mixer while the apparatus is operating. The FIX top surface detection (2a), the FIX water supply solenoid valve (2f), the FIX conduction solenoid valve (2c), and the FIX replenishment pump (3e) of the 7-segment display portion 85 of the display panel 79 in the operation check mode of the chemical mixer are displayed. Check the operating status and identify the abnormal part.

According to the above construction, during the processing of the photosensitive material,
Since an operation check can be performed to detect the on / off state of the sensor or device in the device, it is possible to quickly identify the failure location.

The present invention is not limited to the above embodiment. For example, to enter the operation check mode,
A template as shown in FIG.
By setting the segment display section 85, the operation check mode may be automatically set.
