Hi Friends,

All of sudden my camera started showing the Error: Press shutter release button again.
I removed the lens and checked, the mirror is opend.

I tried clicking shutter button with my two lenses & without lens but no luck :(.

I want to know why it happens? any thing wrong in handling it?

here is the pic...

Mirror Lockup - Day 22/365

I searched on net for the reasons but didnt find any... if you know any links pls share with us.

Have you tried switching the camera off and on again?

It looks like the shutter hasn't been reset after the last firing. A ready-to-fire D40 shouldn't have those tabs visible at the left.

Have you tried taking off the battery or using the reset button?

I had this same problem with the D40 and it began working afer using the reset button. It worked fine for a brief period then started up again with the error message. I took it to a camera shop and they were stumped. In the end I had to send it to Nikon for repair. Hope you don't end up going the same route.

I just ran into this problem all of a sudden today. I was taking a series of pictures at a wedding and it stopped working. It get stuck and would require 2nd button press to bring the mirror down again (thought the mirror does not look like it is completely down).
I had this on a 5month old D60 that has not been used too much.

Any suggestion you have is most welcome.

My first suggestion would be to have a backup body when shooting weddings.

My second suggestion is to give Nikon a call :-).

I Solve It... Hi Guys, I had the same problem few months ago, after reading some similar posts and trying all suggestions I finally took my D40X to Nikon, they spent two weeks in diagnostics to finally said that will cost me 150$ and 6 more weeks, I got my camera back and I try it and it was working perfectly.. but...yesterday, after some months I got the same error, and here is the solution .
I took off the 8 screws at the botton plate and the screw hidden at the edge near the batery (you have to take off the battery).
After taking off the botton plate I saw a red gearwheel and I move it in any direction.. then I put the battery and Viola!!.. worked... then I put back the botton plate... seems that the gear is part of the mechanics of the shutter that probably was stuck.
I Hope this helps, but remember my D40X was out of guaranty, because of that I dared to open it.
You managed to get a viola into your D40x? Are you trying to orchestrate this thread?
ianjofriel PRO Posted 6 years ago. Edited by ianjofriel (member) 6 years ago
LMAO at Viola...

maybe the shutter is damaged after someone printed "project 365 / Day 22" across it ? :D
Steve.Jackson 6 years ago
I had exactly the same problem with 'Error. Press shutter release button again' and i fixed it!

Here's how I did it.

Get a very small cross head screwdriver (watchmaker size)
A can of WD40
Sticky tape
A good light

Remove the Battery and SD card
Open up the bottom of the D40x putting the small screws onto the sticky tape in order of removal.

You might want to take pic with another camera so you know where all the screws go.
Then remove the metal plate (used for the tripod mount, you will need to remove the back of the D40x as well, it's only 2 screws)

Now look at John C Ayr's pic of the D40x www.flickr.com/photos/johncayr/3969534234/

Spray a SMALL amount of WD40 onto the red and white gear wheels.
(Don't use so much that it drips down onto the optics, you don't want oil in there!!!)

Put the battery in and hold it down to make contact, put in the sd card and switch on the camera and try the shutter button. (switch it to manual focus or it might try hunting around for ages for focus)

It might start working, if not move the red wheel a few stops and try again.

Once it's lubed up and the wheels move it should be ok.
Keep taking pics until you feel it is ok.

Then reassemble following the screws backwards on the sticky tape.

Enjoy your D40x once again ;-)

A big thanks to all the contributors in this thread- I just experienced this problem with my D40. I started to unscrew the bottom plate, but 3 of the screws were in too tight for my liking.

I put everything back in its place, and out of frustration, continuously hit the shutter release button for about a minute. It suddenly snapped back into place, and began working again. I suppose my word of advice would be that, before cracking it open, try pressing the release over and over for a while.

I had this happen to me, took a month, Nikon fixed. Said the Aperture control unit was faulty. No charge, but a month no camera.
Thank you so much, !! I have had my D60 for well over a year and never had any problems at all, then today I was shooting and out of nowhere i got this error message. The only thing that was different was that I was shooting with a new lens, a Nikkor AF-S 70-300 4.5-5.6 VR, (ED, IF). I've had it for a week and it has been great so I don't really know if it was any part of the problem or not, it's sweeeet so I hope not! I was really upset and worried so when I found this thread I tried this fix immediately and it worked! Soooo happy and so grateful! Thank you Thank you Thank you!!!

Steve, thanks for the info. Did it take you a while to get the gears to move?

James McLeod, I had the same problem. I was down to the last screw till I could remove the silver plate and ground the screw down to a circle. I jammed a scalpel in the screw to try to create some wriggle room for a phillips screwdriver and almost tore up some electronics. Oops.

I bought my camera refurbished for really cheap and have had it for a year and some months now.

Sadly, it still isn't working. But...I hope giving the gears a little more WD40 will loosen it up. *crosses fingers*

Hi there Guys! I have a D60 and yesterday I had this error message in my camera LCD "Error. Press shutter release button again". I follow the steps that Steve Jackson mentioned in the forum, and when I try to move the red wheel manually, gets to one point when it does not roll anymore. Is this supposed to be like this? I mean, this wheel have an end or it is getting stucked for some malfunctioning? I would appreciate all your comments, I am DESPERATE to get my camera back on track! Thanks in advance!

James J McLeod 6 years ago
I had two concerts to shoot the night following the sticky, pardon the pun, moment.

Initially, after I had taken it apart, I used a cotton bud (HEAVILY covered in WD40) to coat it, only rubbing it as I released the shutter. Did this for about 5 minutes, screwed it back up and left it alone.

Friday night, take a few photos outside; get inside, bands come on and ERROR. Oh shi-
I began to get quite angry and wonder why it had happened again, and then I did what most men refer to- I hit it. I hit the bottom 3-4 times with the button depressed, as I was I at this stage, and it released and began to work again.

10 more shots and it happened again. Followed the above steps and it was working. No more faults.

Saturday rolls around and I discover 3 screws are missing (should've tightened them >_<) and the error has returned.

I took it apart and used tissue paper soaked in it and just coated it as much as I could.

This time at the concert it worked a treat and I've not had any issue since.

Edward Labozzetta 5 years ago
took a leap of faith and the solution worked perfectly, but instead of wd40 I used a light sewing machine oil to lube it up, set camera to sport mode, and fired off repeated shots for about 2 mins.
needless to say everything works better now then it did comming out of the box for the first time. saved myself that $180.00 repair with something that is obviously a design flaw after all the posts and costs I see about this problem. many many thanks to those who posted this fantastic solution. and to those who are nervous about removing those screws and something falling out? trust me it was easy and tighter then a drum, if anything does fall out during this remedy then you got more problems then an error message, simple plate removal and the red dial of death is right there plain as day, gave it a few turns and really wondered if it was that wasy and it was!. I was even able to re-instal the battery and take a test shot to make sure it was working, with the whole thing dissassembled and it did, just hold it in with your thumb before re-assambling to see if it worked. Im confident I could make this repair on the fly at a job. whole process only took 15 mins. and that was on the first go. now that I have done it, should only be about 5 mins. tops. Thanks fellow Nikon users
Niikon. 5 years ago
Thanks Edward will try it.ok let me share two solutions I found even without opening the camera.Noticed that even after the error occured with a metering lens then switch off the camera ,move the dail to shutter proirity or night mode and start again,it works !!!! atleast with my sigma 17-70 HSM.The second one is to remove the kit lens/metering lens and attach a non cpu lens ,will work again with no problems in M mode.Please report if this worked for you.
Niikon. 5 years ago
Actually there are 9 screws to be removed ....8 visible ones and one inside the battery chamber...used 2 drops of switch cleaning oil and put everything back.worked okay for a few clicks then error showed again.Did it for the second time and all scene modes, auto and programme mode works but still shows error in S, A &M......strange!!!
Yes its so easy just try this if your camera is a victim...be sure not to add too many oil drops into the body.

Thanks for the advice - however this didn't work for me.

I took the back off but the tripod mounting plate had 9 screws including 2 which were impossible to get out due to the angle !

I couyld see the red wheel so gave that a small amount of WD40 but it seemed to be working perfectly in the first place anyway.

Looks like it's a repair job now !

Had the same problem. I disassembled my d40x to get to the red and white wheels, sprayed a little "TEFLON-LUB" lubricant as shown in the video, moved the red whell with a small screwdriver so the shutter was working again, and took a lot of pictures until the shutter was operating smoothly before reassembling everything.
So far it is working now....

Yeah this just happened to me today too. And although taking it apart seems like a good idea (i'm mechanically inclined), I'm not too sure about doing it. once I hit the release button again the picture shows in preview but the top half of it just comes out black. It seems like alot of people have had this problem so has anyone been able to figure out specifically, why it does this?
Top part black suggests that the shutter is sticking or not fully opening at any rate

This happened to me as soon as I took the first photo on my camera, and I managed to fix it, but I'm pretty sure it was just good luck.

You get the error usually because the mirror is jammed, so I took the lens off the camera and tried holding the mirror in different positions, mainly in the middle and then pressed the shutter release button whilst holding the mirror, and I managed to get the mirror out of the position it was stuck in.

I had the same problem....had to repeat the repair a couple times, but it seems to be working fine now. So, I'll add that you'll need a good quality #000 phillips screw driver. I wasted a lot of time trying to remove the screws with a cheap set from Radio Shack. Don't waste your time with this. I found a German screw driver made by "Wiha" at the best hardware store in Santa Monica , "busy bee" hardware.

I read another post from a camera technician that said:

1) he had seen a LOT of D40/x/60 lately all gummed up inside from WD40 :(

2) the gear fix mentioned on this thread is most likely temporary. The gear will eventually find the dead spot again.

At any rate, I moved the gear without usuing WD40 and clicked off a dozen or so shots. I will hope for the best until I find a good price on a used D3100 or a low actuation used D40.

Now that I know how to quickly remove the bottom plastic plate to move/unstick the gear/mirror, it will only take me about 5 minutes to repeat when necessary.

I had a similar issue with a D5000. The error would reappear periodically, but it could be cleared by tripping the shutter again. It worked like this for a long time, but it started to happen more and more frequently so I sent it in to NikonUSA for repair.

SOMENJGUY2010 4 years ago
There are some great instructions floating around about having to put some DW40 or sewing machine oil on the 2 gears buried underneath that make the shutter move. there are alot of really small screws to remove be sure to get precise tools and take your time. Its been very difficult to get to both wheels for me. I oiled the red one and tried with out luck. I need to remove the metal cover to get directly to the white gear which I tried to dab with oil. My D40 camera already lost the flash and the SD card door broke off . So its a DIY. Ultimately I believe the gears motors may need to be replaced as I have happily taken many 1000's of continuous sport shots with the D40 and it simply could be burned out. They appear to be replaceable but something I would consider when buying a new nikon DLSR.
domlaguna 4 years ago
I found a very simple solution. Worked for me. I removed my lens and blew hard, with a percussive puff, several times into the camera cavity, right at the mirror area.

Presto. Camera back to normal.

I arrived at this after having read all the above about WD40 and tiny screws and the red gearwheel, I was struck by the report of Amanda Aguirre, who just hit the shutter button repeatedly, and nudged her camera back to life.

From all this, it's clear this is a mechanical problem. So I thought a little jog might just do it. And it did - for me, at least.

Can't vouch for how long this fix will last, but I can always do it again!

Another idea that went through my mind would be to use that special aerosol for cleaning electrical gear. This kind of stuff:

I've no idea if it will work, but personally I'd rather spray this into a camera than WD40. (No offence to the WD40 people - some of my best friends, etc. etc. :-)

Good luck, everyone!

I had the same problem with my brother-in-law's D60 that I borrowed. I had a panic attack thinking I had broken it. He found this thread for me.

I applied the WD40 and rolled the red gear but at first it did not help. I had to roll the wheel and click the shutter release repeatedly. It would half work then stick again. Eventually it freed up and now works fine.

I am concerned about the long-term affect of WD40. The WD40 web site claims it is ok on plastic and rubber, but not on polycarbonate. Quote:

"What surfaces or materials are OK to use WD-40 on?

WD-40 can be used on just about everything. It is safe for metal, rubber, wood and plastic. WD-40 can be applied to painted metal surfaces without harming the paint. Polycarbonate and clear polystyrene plastic are among the few surfaces on which to avoid using a petroleum-based product like WD-40."

Awesome, thanks for the advice! I used WD-40 on the red wheel too, rocked it a bit, and tried again. Same problem. I then manually lifted and released the shutter carefully a few times (with a noticeable click the first time), after which everything seems to be working fine again. Woohoo!

I had this error for the first time today on my D60. It's second-hand and I've had it for over two years, so it's done pretty well to get this far without any errors!

After fiddling with the settings and giving it a whack, it worked momentarily for about three photographs and now doesn't seem to want to do anything at all, so I'm going to give it a rest overnight and then give this red gear fiddling a go and then report back.

Thanks for starting this thread and keeping it so chock full of information guys - makes me feel a lot more confident to try opening it up when there are so many other people reporting back!

papadeltasierra 4 years ago
I have a D40 with this problem and I have a suspicion about the cause. My D40 was a gift (it's broken, if you can fix it...) so with nothing to lose I've been removing more and more casing. I can now see, to the left of the lens (viewed facing the lens) a small silver latched operated by a solenoid. This latch seems to "latch" the shutter at the appropriate point - the problem is it doesn't seem to then unlatch.

With no solenoid power, a small spring is supposed to release the latch but the spring is surprisingly "free" (i.e. there's not tension in it) and I suspect this means the latch goes on, but never comes off. Since the shutter is all driven by the same small motor and gear train (with the "red and white cogs") beloved of this group, I suspect this may be one of the causes of the D40 failing.

At present I don't see how I can get the D40 apart further to confirm this and possibly attempt a fix but if anyone happens to be "in the area" I'd be interested to hear whether they can confirm or disprove my theory.

And my D60 just did it - mirror locked up and nothing working to make it come back down.

Just over 3 years old, I think approx 20K shutter actuations. Not abused. Very disappointed.
From the number of posts on this thread, which one must presume is the tip of the iceberg, this is not an uncommon occurence.

In Australia, these 'entry level' dSLRs command a body only price of about $650 - $700. This is not a trivial amount of money. I really wonder if one should expect a little more in durability.

Hi all,

I also had the problem with my D60. I tried to open the camera, but could not remove the metal tripod plate due to one sturdy screw.

So I could only try to fix the problem with the red gearwheel. I turned the wheel back and forth and tried to make some pictures while holding the battery into place. In the first 3 attempts the error returned after taking a few shots. But, repeating the turning of the wheel (hearing several clicks) seemed to eventually solve the problem. I used a very small amount of WD40 using a cotton swab. I don't think it necessary to use the WD40, especially reading the reports of 'gummed up gears'.

Not sure how long the camera will run, but happy for now. Thanks for the help!

The motot contact hits a dead spot. When you turn the gear you get past the dead spot and the camera works fine till it hits the dead spot again. WD 40 is bad. Don't let it near any parts or outer finish of the camera. My D40 has close to 70,000 shutter clicks and every once and awhile, it dose not fire. When I tilt the camera down, it fires then tilt it up and it's ok. I guess it's age and wear. Don't try to fix any digital camera because you will never suceed.

Reading this thread gives me hope I can fix it......Going to get some mini screwdrivers from the shed in a bit.................

No joy. It's easy enough to remove the 9 screws (including the one in the battery bay) in the base plate of the D5000 with the right screwdrivers, and the red cog is easily visible. You can rotate it in either direction until you come up against a stop with teh mirror either lifted up or fully down. I notice that the inner red cog was white for around half its circumfrence and it looks like those teeth might have been jarred off with the impact when it hit the ground. But the error message remains on so nothing works. doh!

Give Nikon in Kingston a call and see what they suggest. They should also be able to give you an idea of cost.

I've also experienced that and I can say - its really a pain in the butt.

I just wanted to confirm that indeed this method works (call it fluke). On my D40, I didn't had to go as far as removing the silver plate instead just greased the red cog wheel using a needle. You can use any lubrication in moderation. I am not sure if its the lubrication that fixes it or the fact that it goes out of timing and so moving the cog wheel forward and back several times manually fixes it? Please note that you can only wind the wheel back and forth to a certain degree so, forcing it might break it; be careful.
Took me a while to get rid of my error but I continued applying grease at very small quantity and continued manually moving it with needle back and forth. (You can also use toothpick - probably safer).
Also played around with changing camera modes from Manual to P - not sure if that helps.
