Re: Non Model "A" Electrical Question
Capacitors need to be tested removed from the circuit. For a lot less than the price of a decent tester (that you wouldn't use a lot) you can replace all the caps you suspect. Of course, I mean the through-hole type; the surface-mount boards are intended to be throwaways. Swollen caps often mean something else in the circuit has drifted out of spec with age. May be time for a new printer.
