Printed material management system including system and method for controlling a shredder

A shredder comprising:

• an inlet;
• a cutter;
• and
• a scanner,
• wherein the shredder is configured to execute a reading process of conveying a printed material input from the inlet and reading a code printed on the printed material by using the scanner,
• wherein the code is generated by a management program installed in a device different from the shredder,
• wherein the management program is configured to:
• determine a printed material ID for each page to be printed;
• generate the code by encoding the determined printed material ID;
• cause a printer to print the generated code and an image on a page corresponding to the printed material ID encoded in the code on the same sheet;
• and
• transmit a print log including the printed material ID and first data indicating that disposal is not completed to a server,
• wherein the transmitted print log is stored in the server, and
• wherein the shredder is configured to execute, in a case where the shredder successfully reads the code in the reading process:
• a rewriting process of transmitting a rewriting request associated with the printed material ID encoded in the code read in the reading process to the server, and causing the server to rewrite the first data included in the print log corresponding to the printed material ID associated with the rewriting request among print logs stored in the server to second data indicating that disposal is completed, and
• a shredding process of shredding, using the cutter, the printed material subjected to the reading process, and
• wherein the shredder is configured to execute, in a case where the shredder does not successfully read the code in the reading process:
• a discharge process of discharging the printed material subjected to the reading process, to the outside of the device without shredding the printed material instead of the rewriting process and the shredding process, and
• wherein the shredder is configured to, in a case where the shredder does not successfully read the code in the reading process:
• execute the discharge process without executing the rewriting process and the shredding process;
• and
• shifts to a retry mode, and
• the shredder is configured to convey the printed material input from the inlet at a first speed in the reading process and a mode different from the retry mode, and
• the shredder is configured to convey the printed material input from the inlet at a second speed lower than the first speed in the reading process and the retry mode.

A printed material management system comprising:

• a non-transitory computer readable medium storing a management program;
• a server;
• and
• a shredder,
• wherein the management program is configured to cause a controller of a device in which the management program is installed to execute:
• a print data acquisition process of acquiring print data,
• a generation process of determining a printed material ID for each page to be printed based on the print data acquired in the print data acquisition process, and generating a code by encoding the determined printed material ID,
• a printing process of printing the code generated in the generation process and an image on a page corresponding to the printed material ID encoded in the code on the same sheet using a printer, and
• a transmission process of transmitting, to the server, a print log including the printed material ID and first data indicating that disposal is not completed,
• wherein the print log transmitted by the management program is stored in the server,
• wherein the shredder includes an inlet, a cutter, and a scanner, and
• wherein the shredder is configured to convey a printed material input from the inlet and execute a reading process of reading the code printed on the printed material using the scanner,
• wherein, in a case where the code is successfully read in the reading process, the shredder is configured to execute:
• a rewriting process of transmitting a rewriting request associated with the printed material ID encoded in the code read in the reading process to the server, and causing the server to rewrite the first data included in the print log corresponding to the printed material ID associated with the rewriting request among print logs stored in the server to second data indicating that disposal is completed;
• and
• a shredding process of shredding the printed material, which is read in the reading process, using the cutter, and
• wherein, in a case where the code is not successfully read in the reading process, the shredder is configured to execute:
• a discharge process of discharging the printed material subjected to the reading process to the outside of the device without executing the rewriting process and the shredding process and shredding the printed material, and
• wherein the management program is configured to, in the generation process:
• acquire a printer ID for identifying the printer;
• determine the printed material ID including the acquired printer ID for each page to be printed based on the print data acquired in the print data acquisition process;
• and
• generate the code by encoding the determined printed material ID, and
• wherein the shredder is configured to continuously conveying a plurality of printed materials one by one,
• wherein the shredder is configured to, in a case where the shredder reads the code from a leading printed material which is a printed material conveyed first among the plurality of printed materials in the reading process, execute a storage process of storing, in a memory, a leading printer ID that is a printer ID included in the printed material ID encoded in the read code, and
• wherein the shredder is configured to, in a case where the shredder reads the code from a subsequent printed material which is a printed material conveyed after the leading printed material among the plurality of printed materials in the reading process and the printer ID included in the printed material ID encoded in the read code matches the leading printer ID, execute the rewriting process and the shredding process on the subsequent printed material, and
• wherein the shredder is configured to, in a case where the shredder reads the code from a subsequent printed material which is a printed material conveyed after the leading printed material among the plurality of printed materials in the reading process and the printer ID included in the printed material ID encoded in the read code does not matches the leading printer ID, execute the discharge process on the subsequent printed material without executing the rewriting process and the shredding process on the subsequent printed material.
