With this feature, you can save device logs that are stored in the flash memory or the SD card. If an operation error like SC or jam caused by the software occurs, you should retrieve the device logs that have stored in the machine so that the analysis of the device logs will be performed smoothly. (There is no need to wait until the problem reappears. You can do the work timely.)

There are two types of retrieving the device log.

you can retrieve the device log stored in the machine by using SD card slot when an error occurs.

you can retrieve the device log continuously by installing the option SD card slot to the machine.

  • Analysis of the device log is effective for problems caused by the software. Analysis of the device log is not valid for the selection of defective parts or problems caused by hardware.

Types of device logs that can be retrieved

Retrieving the device logs saved in the machine

Type

Storage Timing

Destination (maximum storage capacity)

Controller debug log (including operation log)

  • Saved at all times

eMMC of the GAU (1,480 MB/about one week;Operation day: 5 days/ No print: 2days)

When the data gets over 1,480 MB, the older data is deleted.

Engine debug log

  • When an engine SC occurs (communication system and reset system are excluded)

  • When paper feeding/output stops because of a jam

  • When the front cover opens (if you close the cover, retrieving the log are stopped)

  • When the media holding lever is raised. (if you lower the lever, retrieving the log are stopped)

  • When the cartridge is unlocked (One or more white ink cartridges are unlocked. For cyan, magenta, yellow, and black ink cartridges, all the same color ink cartridges are unlocked.) (if you lock the lever, retrieving the log are stopped)

  • When pre-heater cover opens (if you close the cover, retrieving the log are stopped)

  • When the roll holder opens (if you close the cover, retrieving the log are stopped)

  • Supply end (One or more white ink cartridges have run out of ink. For cyan, magenta, yellow, and black ink cartridges, all the same color ink cartridges have run out of ink.)

  • Power is turned off

eMMC of the GAU (700K multiplied by 300 times (maximum) is 205 MB/about 30 days)

When the data is output over 300 times, the older data is deleted.

When the file size reaches the maximum size, the older data is deleted.

Saving is automatically performed when SC or jams occur. Therefore, no advance preparation is required and an after-the-fact log can be acquired. However, the log does not provide information on errors other than SC and jams, nor does it provide information on SC/jams which occurred more than 10 pages previously. In such cases, it is necessary to acquire a log using the Service Slot Board (Service Option) method.

Retrieving the Device Logs Continuously when the Service Slot Board (Option) is Installed

You can store the following device logs continuously by installing the service slot board.

Type

Save Timing

Maximum Capture Period

Use

SDCU (for engine)

A log is continuously saved when an SD card is inserted.

Approx.800 days for an 8GB SD card (assuming about 10MB of use per day)

The normal log (The log that captured by the log command.)

The flown log (The log that displayed on the monitor)

SDCU (for engine)

A log is continuously saved when an SD card is inserted.

 Approx.22 days for a 32GB SD card (assuming about 1.4GB of use per day)Information about motor control

It is necessary to install a Service Slot Board in the machine in advance and to insert an SD card. When a Service Slot Board is installed, the log is continuously acquired for a long capture period. Therefore, the log provides information on errors other than SC and jams, as well as information on SC/jams for a longer time period.
