01J Power On and LVPS Control Signal RAP
Use this RAP to check and identify power on and standby signals from the LVPS.
Also use this rap to identify problems that occur at or shortly after installation of machines fitted
with a
TAG 155
IOT PWB.
If any of the following problems occur on machines with a
TAG 155
IOT PWB, go to the
Tag
155 Procedure
:
•
Machine shuts down 4 to 6 seconds after power on
•
Machine reboots
•
Green screen at power on
•
Copying and printing unavailable
•
No media trays available
•
Scanner unavailable or failed to initialize
•
Configuration sheet does not auto print at power on
•
IOT memory corruption
•
Lost communications between the IOT PWB and the SBC PWB (fault code 03-300)
•
Increased paper jam rate
•
General print engine problems
•
General finisher problems
Procedural Notes
NOTE: Short circuit or overload of +3.3VSB (standby) will result in all the LVPS outputs off.
Short circuit or overload of +3.3V or +5V will result in all the LVPS outputs off, 3.3VSB.
NOTE: For an explanation of the LEDs on the IOT PWB and their function, go to
OF7
IOT
PWB Diagnostics RAP.
NOTE: +3.3VSB (standby) is generated from the LVPS when the machine is connected to the
AC supply. +3.3VSB is required to initialize the machine from standby to power on.
NOTE: Ensure that the
01C
AC Power RAP is performed before starting this RAP.
