Might be worth adding what lens you were using and if its always the same lens which gives you the faults, if its quite recent, it could be temperature related.
Is the battery fully charged, and have you checked the latest firmware for any updates ?

Thank you for your reply Chris.
The lens is 35mm F2.8 Macro Limited and I use it all the time unless the subject demands a zoom telephoto lens or a wide angle lens.
Recently all the shots are taken with the camera newly taken from the house which is 23 degreesC 24/7.
When the problem started the first thing I did was fully charge the battery.
All the shots were taken with the camera dial set at Auto.
I have not checked the latest firmware, it was updated earlier this year.

Thank you Chris.
I just swapped lenses to a 55-300 ED and got 5 dark images and one good one.
Guess that it is a camera body issue.

Ok, now thats identified, suggest you check the firmware version then reset the body to factory defaults to see if its something you've accidently done.

One of the first things to check is that the contacts on lenses and in the camera body are clean and free of grease. Carefully wipe with a soft, dry cotton cloth.
Best regards, John

I suppose it could be the aperture motor problem, same as experienced by some with their K-30s. If you have any warranty left on the camera, get it sent back for repair before the guarantee runs out.

Thank you for suggesting this John, I have done it.
I am waiting now to take more shots when a decent time interval has passed since the last effort .
Tomorrow morning will be OK.

I have read that the mechanism for the K-30 is used on the K-s2 and other models.They should have solved the problems before the K-s2 was put into production but may not have done. My body is out of warranty, would SRS Microsystems workshop be able to fix it?
There is a DIY method of fixing it on Youtube but I don't fancy using it.

When and where did you purchase it? It might have a two year guarantee and the camera wasn't released until 2015 so many must still be in warranty.
You could ask SRS about repair but I'd expect then to send it to the official Pentax repairers who are Johnsons Photopia Ltd, Hempstalls Lane, Newcastle under Lyme, Staffordshire ST5 0SW Tel: +44 (0) 1782 753350
Email: [email protected]">[email protected] so maybe better to deal directly.
Alan Marlow of Shepperton might deal with it too: http://www.cam-rep.co.uk/ at a more favourable cost.
Given how common this problem is, it's clearly an inherent fault that shows up in several Pentax models including the K-30, K-50, K-70, K-S1, K-S2 so Ricoh ought to do the responsible thing and sort the problem out for affected owners FOC.
There are home remedies in various forum threads such as this:
https://www.pentaxforums.com/forums/151-pentax-k-30-k-50/321871-k-30-k-50-apertu...
The camera should be expected to last for a reasonable period of time. If it really worries you you have six years to take a claim to the small claims court for faulty goods in England, Wales and Northern Ireland, and five years in Scotland. For help with this see https://www.citizensadvice.org.uk/law-and-courts/legal-system/taking-legal-actio...
Someone here got it fixed by Pentax outside the warranty period. See https://www.pentaxuser.com/forum/topic/the-dreaded-k30-aperture-motor-failure-st...

Thank you John K for such detailed advice.
I bought it from SRS on 18th June 2015, two year warranty, so about 6 months past the warranty.
If the problem is still there tomorrow I will ask SRS about it.

This, 1000 times this.
You can test this if you have a lens with a manual aperture ring. Manually set the desired aperture on the lens (old fashioned way) instead of letting the camera do this for you. If you don’t get any dark frames you most likely do have the aperture mechanism failure.
I did get mine fixed by Pentax under warranty, but I was left pretty disgusted with their response to this, especially those who weren’t helped out of warranty. It was significant enough to warranty a recall, but they preferred the silence approach.
Anyhow, try the test above if you can, and if needs be get straight onto organising a hopefully free repair.

I had a similar problem a few years ago, i was advised by a kind forum member to wipe the contact points on both the body and the lenses with a lint free cloth as John has suggested, i was shocked how much much muck came off and the problem was resolved, i hope you have it as easy with your problem

I don't have a lens with a manual aperture ring, John K.
No change today, still get dark frames. Will speak to SRS.
Thank you Maria.

The number of dark images varies, the most being six.
Here is the same subject showing adjacent shots
Can anyone suggest the reason for this occurring?
