Replacing Power Supply on IR 1670

[happyhshoe]

Ok,
I realize that this is everyone's favorite machine, but I have a customer's IR 1670 in the shop onaccounta it keeps throwing E000's/E003's. I found something today which makes me want to replace the power supply anyway, but I am wondering whether anyone has seen this, and has any ideas?

Let me know,

Detecting an Error

Outline
The machine checks for an error for the following in relation
to fixing temperature control:

[1]Temperature error detection by main thermistor
[2]Temperature error detection by sub thermistor
[3]Temperature error detection by thermal switch

Control in Response to an Error

•If the machine detects an error in the fixing assembly, the DC controller PCB operates
as follows:
>>> It causes the FSRDRV* signal to go ‘1’ to cut power to the fixing heater.
>>> It causes the RLYDRV signal to go ‘0’ to turn off RL1, and indicates ‘E000’ through ‘E004’ on the LCD in the control panel.
When ‘E000’ through ‘E004’ is indicated, the NVRAM on the DC controller PCB remembers an error in the fixing assembly even when the
power switch is turned off and then on.
After turning on the power, be sure to execute the following in service mode to remove the error information:
#7 PRINTER > #4 PRINTER RESET > YES = (*).

Conditions for Error Detection

The machine will detect an error in response to any of the following:
a. Start-Up Error
A start-up error is identified for the following (reading of the main thermistor):

•It exceeds 40°C, but does not reach 60°C in 10 sec.
•It exceeds 60°C, but does not reach 80°C in 10 sec.
•It exceeds 80°C, but does not reach 100°C in 10 sec.
•It exceeds 100°C, but does not reach 120°C in 10 sec.
•It exceeds 120°C, but does not reach 140°C in 10 sec.
•It exceeds 140°C, but does not reach 160°C in 10 sec.
•It exceeds 180°C, but does no reach 195°C in 10 sec.

b. Low Temperature Error
•The reading of the main thermistor does not reach 40°C within 14 sec after the fixing
heater goes ON.
c. Low Temperature Error at Time of Temperature Control
•After the end of the Wait period, the reading of the main thermistor is 100°C or lower.
•At time of standby, the reading of the sub thermistor is 50°C or lower.
d. High Temperature Error
•The reading of the main thermistor is 220°C or higher.
e. Drive Circuit Error
•At time of initialization, the ZEROXI* signal of the power supply cannot be detected.
•The ZEROXI* signal does not arrive for 3 sec during temperature control.
•A triac short is detected (ASIC).
