Brother MFC-9130CW intermittently won't power on.

[David Farber]

We've had this Brother MFC-9130CW printer/scanner/fax for about 3 years.
Sometimes (about twice a week) when you try to power it on, it doesn't
go on. The internet is full of similar complaints about this issue. The
"fix" is to unplug it for a minute and then plug it back in. This
workaround always works. I'd be more interested in finding out how to
permanently fix it. It worked fine for the first two years plus. Has
anyone disassembled one of these and found a cure for this?

Thanks for your reply.

when you say you "try to power it on"

do you mean you push the physical power button on the printer?

or is the printer in sleep mode and you send it data which is supposed to wake it up?

Every evening I hold the power button down for a couple of seconds until
it powers off completely. It is not in sleep mode. The only way to use
it again is to hold the power button down for a couple of seconds until
it powers back on. Then you can use it. I'm about to go hunting for some
disassembly instructions because it wouldn't power on again today.

Thanks for your reply.

Not yet, though I did find a service manual.

Take note (on page 331) of the extensive procedure required if you ever
had to replace the power supply board .

When the problem becomes more frequent and annoying, then I'll
disassemble it and look for cold solder joints, failing capacitors, etc...

Thanks for your reply.
