■ Limitations ■
When■the■operation■on■debug■log■goes■wrong,■repeated■log■collection/setting■change■can■
cause■faulty■behavior■such■as■generating■extra■temporary■file■and■log■file.■In■such■a■case,■
execute■"DEFAULT"■and■reset■the■settings■on■debug■log,■and■then■try■again.
■ Confirming■the■Existence■of■Debug■Logs■(HIT-STS) ■
This■service■mode■confirms■whether■debug■logs■exist■in■the■auto■save■area.
"OK!"■is■displayed■if■logs■exist■in■the■auto■save■area.
NOTE:■
The■status■also■shows■"OK"■by■holding■down■the■counter■key■+■1.2.3.■
■ Initializing■the■Debug■Log■Settings■(DEFAULT) ■
Set■all■debug■log-related■settings■back■to■the■default■settings■(the■state■at■the■time■of■
shipment).
•■ You■must■perform■this■measure■when■you■complete■troubleshooting■and■return■the■device■
to■the■customer.■(Operations■required)
•■ Perform■this■measure■when■you■reset■or■make■another■settings■relating■to■debug■log■during■
a■log■collection■investigation.
For■log■files■that■were■automatically■stored■in■the■debug■log■storage■space■secured■in■the■
machine's■controller■(/var/xpt/dbglog),■they■kept■to■be■stored■unless■the■number■of■log■files■
exceeds■the■limit.■To■delete■the■stored■log■(to■use■HIT-STS),■use■"LOG-DEL"■described■later.
■ Deleting■Debug■Logs■(LOG-DEL) ■
This■is■a■function■to■delete■log■files■that■have■been■automatically■stored.■The■settings■on■log■
operation■such■as■the■log■storage■trigger■are■not■cleared.
Normally,■there■is■no■need■to■use■this■function■(the■firmware■automatically■restricts■the■upper■
limit■for■the■number■of■stored■logs);■however,■it■is■necessary■to■delete■logs■by■LOG-DEL■when■
using■HIT-STS■to■see■whether■the■log■is■collected■or■not■after■changing■the■log■storage■trigger■
setting.
(Because■the■HIT-STS■status■always■shows■OK■as■long■as■there■is■a■log■that■has■been■
stored.)

Collecting■the■Log■of■Key■Operations
■ Overview ■
•■ The■key■operation■log■function■collects■key■operation■log■of■the■user■to■identify■the■cause■of■
an■error■such■as■a■wrong■FAX■transmission,■to■see■whether■the■error■is■caused■by■a■failure■
in■the■machine■or■a■wrong■operation■of■the■user.
•■ The■key■operation■log■is■not■recorded■with■the■status■at■the■time■of■shipment.
•■ A■setting■is■ready■in■"Setting/■Registration"■menu■to■enable■the■saving■function■of■key■
operation■log.
•■ Only■when■the■above■setting■is■enabled,■the■machine■determines■that■the■user■permission■
has■been■obtained■and■starts■recording■user■operation■log.
•■ User■operation■log■is■saved/collected■to■be■included■in■sublog■when■the■sublog■is■saved.
•■ Among■the■user■operation■log■that■was■saved,■the■following■confidential■information■is■
masked.
•■ Password■entered■from■the■software■keyboard
•■ Password,■PIN■code,■etc.■entered■from■the■numeric■keypad
•■ Character■strings■displayed■with■turned■letters■on■the■UI■screen
NOTE:
•■ When■the■log■is■output,■information■such■as■passwords■and■PINs■is■output■as■masked■
characters.■This■can■help■prevent■sensitive■information■from■being■leaked■externally.■
•■ Collect■this■log■when■it■is■determined■that■analysis■of■the■firmware■debug■log■is■required.
