Re: OLD Xerox DC 4 LP U3-5 Error

while not overly helpful, I was able to find this from a service manual found online:


Problem:U3-5 error code at power up.Cause:Lack of  switched  +5 VDC due to a 
damaged LVPS.
note-ROS, MCU as suggested by FIP and Top Cover Interlock Switch  (152925) were 
replaced unsuccessfully.
