Output device, log collecting method for output device, and storage medium

摘要

The purpose of this invention is to acquire log information of all System on Chips in an output device for debugging without having much effect on existing functions of the output device and conducting complicated steps. If a storage device preliminarily formatted with a predefined volume label is connected to the output device, log information read based on the same volume label as the volume label of the storage device is written to the storage device.

主权项

1. An output device, comprising:
a detector to detect that a storage device formatted with a predefined volume label is connected to the output device; a reading unit to read log information of the output device based on the same volume label as the predefined volume label after the detector detects that the storage device is connected; a writing unit to write the log information read by the reading unit to the storage device; and a plurality of communicably connected System on Chips, wherein a System on Chip to which the storage device is connected functions as a master System on Chip and a System on Chip connected to the storage device via the master System on Chip functions as a slave System on Chip, and log information of the master System on Chip is written to the storage device and log information of the slave System on Chip is written to the storage device via the master System on Chip in response to a request from the master System on Chip to acquire log information.
