Canon Scanner cold cathode light replacement.

Guest
Hi all,


I've got a Canon D660U flat bed scanner. The cold cathode light has
dimmed and the scanner is reporting an error along the lines of
needing more warm up time. Tried another PC - same problem. DC supply
to scanner from wall is OK when plugged in.

I assume that the lamp is failing. Have talked to Canon service agent
and the unit is not repairable, can't get any part short of a
replacement scanner.

1. Does anyone know what the drive voltage for the lamp should be? So
I can check that the lamp power supply is OK

2. Is there a source for these lamps other than Canon? Although the
colour temperature of the lamp could be an issue if there is no exact
replacement.

3. Should Canon still make parts available for this 2.5 year old
scanner? (Yeah, I probably already know the answer here!)


Thanks for any useful info.

- Rob.

If it is very cheap it simply may be designed not to have this part
replaceable.

I bought a canon scanner a few months ago for $80 bucks. I will be
stoked if it's still going in 2.5 years time. Cut your losses and buy
a new one. Otherwise just fuck with it till you can make it do
something usefull.

I know this probably isn't the answer you want to hear, but a new
scanner is well under $100. For $150 you can get a scanner, colour
copier and printer all in one. It wouldn't be worth anyones time to
try and fix it. This is why Cannon wouldn't bother with parts or
trying to service such a thing.
I'd be very surprised if you could get parts for a low cost consumer
computer product like this.

300mm cold cathode from jaycar = $30 (if yours is the CC version and not
lide)
new scanner = $60 - $300

Thanks for the replies guys.

The reason I want to give it a little more life is that it has a
slide/transperancy scan function, it cost around $300 new. As far as
the light source, I assumed it was CC but what is LIDE? (excuse my
ignorance!)

Uses an LED instead of cold cathode, quite cheap and very compact

I thought the film scan unit used a light source in the lid?

Is this the one that is built into the lid, they just use a mirror or
reflector

As far as I can see, the lid bit isn't the problem. The scanner won't
get that far because it knows there is an issue with the CC light
source, so the film part is useless as well.

BTW it is CC and not LED. The CC and CC power supply looks very much
like the Jaycar units, but they are longer. Maybe I should cut one of
those down to size ;-).
