ABSTRACT:
Disclosed in a history information providing device for use in a printer, such as a laser beam printer, having a print producing section, operation watching sensors and a programmable control section for controlling the print producing section. The history information providing device includes a non-volatile memory for taking-out the latest failure information such as the number of times of paper jam and the number of times of toner supply, and the latest maintenance information such as the total number of pages of printed paper and the total number of pages of printed paper by paper sizes, from the sensors and storing the latest failure and/or maintenance information therein. The device also includes a print-out instructing circuit for producing a print-out instruction to print out at least a part of the failure and/or maintenance information stored in the non-volatile memory and the secondary history information obtained from the failure and/or maintenance information. When the print-out instruction circuit has produced a print-out instruction, a part of the latest history information stored in the non-volatile memory is read out corresponding to the produced print-out instruction, and the read out part of the latest history information is subjected to calculation or modification, if necessary, and printed out by the printer per se.
