The recovery detection sensor 263 may be implemented as a lever type or a switch type sensor. The recovery detection sensor 263 plays a very important role of detecting the recovery of the printing sheet when the solenoid 261 does not operate properly. When the printer 200 detects an abnormality of the recovery operation of the printing sheet through the recovery detection sensor 263, the printer 200 outputs a message indicating the abnormality of the recovery operation on the printing sheet through the display means or the alarm sound transmitting means. Notify the administrator by doing this. Therefore, the administrator grasps the abnormal state of the recovery operation for the printing paper output through the display means or the alarm sound transmitting means, and replaces the solenoid 261 so that the printer 200 normally performs the recovery operation of the printing paper. Make it work.

The collection box 270 is a box having an open top surface, and may be inserted into the printer 200 like a drawer to be fixed or pulled out to be exposed to the outside. The collecting box 270 accumulates the printing sheet in the order in which the printing sheets recovered by the collecting unit 260 are collected. The loading sensor 271 may be implemented as a lever type contact sensor, and detects the loading amount of the printing paper accumulated in the collection box 270. The printer 200 may not recover the printing paper when the loading capacity of the printing paper detected through the loading detection sensor 271 is greater than the stackable capacity of the storage box 270. Detect beforehand. The printer 200 prints the printing paper when the loading amount of the printing paper loaded in the collecting box 270 is greater than or equal to a predetermined amount to prevent a situation in which the printing paper loading amount is exceeded through the display means or the alarm sound transmitting means. Print a message requesting the collection of paper. Accordingly, the manager pulls out the collection box 270 and exposes it to the outside to collect the printing paper loaded in the collection box 270 so that the printing paper can be recovered from the printer 200.

The storage box 280 is a box having an open top surface, and may be inserted into the printer 200 such as a drawer to be fixed or pulled to be exposed to the outside. The storage box 280 loads printing paper such as continuous paper, A4 paper or B5 paper, and supplies the printing paper to the printer 200 through the printing support 210. The remaining amount sensor 281 detects the remaining amount of the printing paper remaining in the storage box 280. The residual amount sensor 281 may be implemented as a lever type touch sensor. The printer 200 may print all of the data to be printed due to lack of the printing paper when the remaining amount of the printing paper detected by the remaining amount detection sensor 281 is less than the data amount to be printed on the printing paper. Therefore, the residual amount of the printing paper is detected in advance in order to block such a situation in advance. The printer 200 outputs a message indicating a shortage of the printing paper when the remaining amount of the printing paper is less than the printing data amount through the display means or the alarm sound transmitting means. Therefore, the administrator can check the message indicating the low state of the printing paper through the display means or the alarm sound transmitting means, and then refill the printing paper in the storage box 280 so that the printer 200 can print the printing paper. Do it.
