Abstract

PURPOSE:To certainly grasp data at a necessary time by storing the maintenance data of an apparatus loaded with a non-volatile memory in the operation history of said apparatus in the non-volatile memory and reading said data from the volatile memory to output the same. CONSTITUTION:Sensors 1a-1d detect the events becoming the factors of the history of an apparatus such as the residual amount of toner, the total number of printing sheets, trouble such as the generation of jamming or the like. An analytical processing control part 2 takes out data from a non-volatile memory 3 to compare the same with the data from the sensors to judge the same and the newest data is written in the memory 3. A memory data output control part 5 takes out apparatus history data and the maintenance data analyzed based on said data through the analytical processing control part 2 when the request of the apparatus history data is inputted through an operation panel 4 and converts the same to a definite data form to output said data form from an output device 6.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a printing device, and particularly to maintenance and management of a printing device.

[Conventional technology]

Conventionally, in the case of repair and maintenance when a failure occurs in this type of printing device, the unique history of the device is often the deciding factor in investigating the cause of the problem. Most of the information was recorded and stored manually.

[Problem to be solved by the invention]

The device-specific history of the conventional printing device mentioned above is
Artificially checked and using a list of items in a fixed format,
This has the disadvantage that it cannot be known unless it is recorded and stored periodically or every time a failure occurs, and information that is the deciding factor in fault investigation is often missing.

[Means to solve the problem]

The printing device of the present invention includes a non-volatile memory for storing the device history, a mechanism for detecting events that may be a factor in the device history, a device for processing the events and a timekeeping mechanism of the host computer, and a device for processing the events using the timing mechanism of the host computer. The device has a mechanism for extracting device history information via the device.

〔Example〕

Next, an embodiment of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram of an apparatus according to an embodiment of the present invention. The sensors 1a to 1d detect events that are factors in the device history, such as the remaining amount of toner, the total number of printed sheets, or failures such as jam occurrence. The analysis processing control unit 2 takes out information from the nonvolatile memory 3, compares it with the information from the sensor, and writes the latest information into the memory 3. In statistical processing, processing is performed in units of time based on control codes sent from the host computer. The memory information output control unit 5
When a request for device history information comes in from the control panel 4, etc., the device history information and maintenance information analyzed based on it are retrieved from the memory 3 through the analysis processing control unit 2, converted into a certain data format, and sent to the second Output 6 as shown in the figure is performed.

〔Effect of the invention〕

As described above, in the present invention, a sensor detects an event that is a factor in the device history, and sends the event to a control unit that analyzes and processes the event. In the control section, information is extracted from the non-volatile memory in advance, and then arithmetic processing is performed on the event using the clock mechanism of the host computer, and certain information that needs to be stored is written into the memory. This makes it possible to retrieve the latest device history and maintenance information written in the memory in response to a request using the memory information output control section and the analysis processing control section, making it possible to retrieve the latest device history and maintenance information written in the memory using the memory information output control section and analysis processing control section. This makes it possible to reliably obtain information that is determined to be necessary in advance when it is needed.
