Re: Error 99

Or this from www.camerahacker.com:

Err 99: SYSTEM
DESCRIPTION: This error occurs if there is an internal malfunction detected
during the camera's self-checking procedure that's executed before every
attempted exposure. This is somewhat similar to the flashing 'BC' warning
that occasionally appears on EOS-1 series 35mm SLRs.

REMEDIAL MEASURE: Try releasing the error by turning the main power switch
OFF and then back ON. If this does not solve the problem, have the EOS D60
examined by a qualified service technician. Please be careful to note the
conditions under which the error message occurred. This error is similar to
Error 09 or Error 10 on the D30.

I seem to remember seeing the error 99 for come up on a sporting
photographers website a long while ago. Maybe even a year or so. From
memory someone found out out it is a code which covers a multitude of
problems. Lenses, cards, shutter etc. I'll see if I can find it again
before I send this reply off I think.

OK. Here 'tis. Try this for starters. They don't specifically mention the
350D

Next time it happens, just the lens release button and rotate the lens
like you are going to take it off. Then rotate it back and snap it
back into position on the camera. That often helps and will clear the
error (but you still need to reboot the camera).

It says it is dirty contacts, which means it is sending an electrical
signal somewhere and it's not getting back what it things is the
correct response. But it could be any number of problems. It may be
the lens itself. Try swapping out the lens and see if it makes it go
away.

On one of my lenses, which is old and needs cleaning or replacing, it
is because the focusing motor is hanging up. The camera tells the
motor to move and it doesn't, so it throws an error. So the same error
could be a focusing motor problems, a zoom problem, an error inside the
lens or just about anything related to the lens.

So first test the lens. If you swap lenses and it goes away, then
fine. Fix/replace the lens. Otherwise it could be something more
serious.

The only reason wiggling the card worked is that it distracted you
enough that the lens fixed itself. Sort of like doing a rain dance.
Do it every day and eventually it will rain, so you dance worked.

If it isn't that, I also think that was the error I got before my
shutter flew into pieces (twice). But that's sort of a rarity, so go
with the lenses first and don't worry about the shutter.

Good luck.

My 350d has been producing error 99 more and more frequently. I checked
the
manual (ages ago) and I seem to recall that it mentioned memory card
problems for error 99.

The scenario: The camera takes hundreds of successful photos, but
whenever I
change the battery and turn the camera back on, I get error 99. I have
to
then turn the camera off, open the CF card slot and wiggle the memory
card,
then turn the camera on again. This wiggling sometimes has to be very
firm
and normally I have to wiggle it several times to get the Error 99 to go
away. It has not got to the stage now where I feel like I will snap the
CF
card as I have to 'wiggle' it so hard to get rid of the error. I have
another CF card and another battery and all combinations produce the
same
results.

I googled for this error and found a page saying to clean the contacts
on
the lens and camera. I don't understand how this related to a memory
error,
but I tried it last night and much to my surprise it worked. However the
error 99 is back again today. A quick clean of the contacts again and
its
gone (no CF card wiggling required).

Can anyone shed some light on this bizarre error for me and explain why
cleaning the contacts seems to help. Is there a more permanent fix,
other
than sending my camera away for (probably expensive) repairs?

Cheers,
GT
