Hi Larry,
I am working in the same. I have a fuser of a HP 4L. Do you have
information over the exactly frequency of operation for this fuser??
When the paper (or the pcb) is running inside the fuser, then the fuser is
all the time On or ever the fuser is on and off ?
Thanks, and sorry by my english.
