Firmware Update - Toshiba e-STUDIO 5540C Service Manual

[B] Firmware update
(1) Install the ROM to the download jig (K-PWA-DLM-320).
Make sure the direction is correct.
(2) Press the [ON/OFF] button on the control panel to shut down the equipment.
(3) Remove 2 screws and take off the finisher board access cover.
(4) Connect the download jig with the jig connector (CN28) on the finisher control PC board.
(5) Press the [ON/OFF] button while simultaneously holding down the [0] and [8] buttons.
Updating starts and the LED on the download jig lights.
(6) When the update is completed normally, the LED on the download jig starts blinking. The LED on
the download jig starts blinking approx. 60 seconds after the update started. It is assumed that
the update has failed if the LED does not start blinking even after 90 seconds have elapsed, or if
it repeats blinking 5 times, going out for 2 sec., blinking twice and going out for 2 more sec. This
is a blinking error.
In this case, turn the power OFF and check the following items. Then, clear the problem and
restart updating from the beginning.
• Is the downloading jig connected properly?
• Is the ROM attached to the downloading jig properly?
• Has the update data been written correctly to the ROM on the jig?
• Is the download jig or the equipment damaged?
• Is the connector (CN25) on the finisher control PC board properly connected with the one
(CN5) on the interface PC board?
• Are the connector (CN4) on the Interface PC board and the connector (CN4) on the hole
punch control PC board connected properly?
