Thank you.
I have a copy of the troubleshooting guide and went through it partially before switching to the ¡®failed¡¯ assessment of the power supplies (see oopsy). I need to finish reading it. It¡¯s well worth the read even if you don¡¯t have a scope. It¡¯s a nice methodology to troubleshooting.

assume is an abbreviation not a (transitive) verb.
Checking R4325 the drop is
0.41 volts
4.539v
4.127v
Looks like that should be 5.4v according to the schematic.
::oopsy::
I rechecked my notes and missed that the ripple on the 5v supply is I thought I wrote 9mv not 0.9v. The others appear to be in spec. Got some work to do.
If you don¡¯t make mistakes you¡¯ll never learn anything.

If anyone has purchased the electronic manuals from Q-service. Is the PDF searchable and does it have a populated table of contents? I emailed them a few weeks ago with no response.
I have access to a plotter and 11x17 printer so I¡¯d like to print out some high quality schematics.
::even farther off topic::
I bought a GBC c800pro binding machine on eBay last year for $40USD and free shipping. I print and bind everything now.
