Check the status of the server that manages the image log and the network status, and eliminate
whatever is obstructing image log transfer to the image log server.
Perform of the two following steps.
• Check that [At power On] or [End of selections] is set to [Enabled] under [Transfer Timing] and
transfer all non-transferred logs. However, if only [At power On] is [Enabled] under [Transfer
Timing], you must turn the power on/off to transfer non-transferred logs.
• On the control panel change the [Assurance Level] setting to [Low].
In this case, image logs may be deleted sequentially without being transferred.
When turning the power OFF/ON or automatically rebooting with PostScript, turn the printer OFF/
ON again.
