Hi
I was referred to this group by Vintage Computer Forums at
vintage-computer.com.
I was told a Al Hartman at this list might have the info I need.
I have an Epson FX-185 impact printer. It was in storage for several
years. It now makes a constant high pitched noise from the speaker as
soon as it is turned on. The noise is definitely coming from the
speaker. It is supposed to do so when out of paper. The out of paper
sensor is functioning correctly I even disconnected that sensor from the
board and still get the sound whether or not the circuit is completed.
No bulging capacitors. Parts of the board are grungy. Wondering how to
go about cleaning the circuit boards.
