"resilient hair" on pictures
Also if you don't hold the canister completly upright then it sprays out I think liquid oxygen which'll again so some damage :shock: Not liquid oxygen!! You'd need much higher pressures or much lower temperatures to keep LOX liquid. And you'd also risk some exciting fires - liquid oxygen is a ve...

M50f1.7 problem
It's probably the middle (single) lens. Flip that over and give it another try. Don't ask me how I know......:oops: To be honest it is hard to see any difference in lens curvature looking at a side view of that lens. I've reversed the front and rear elements (at least twice!) with little effect, bu...

Focus screen and mirror box
DIY job. Pentax expects owners to change the focus screen them selves I would avoid compressed air as it may drive dust further into the camera. Blower to remove loose dirt and/or very clean brush like an artic butterfly to wipe off base of prism. Avoid touching the mirror as it is front silve...

K-7 won't stop lenses down....
Ensure the 'A' setting on the aperture ring is selected with any lens that has one. Try cleaning the electrical contacts between camera and lens on camera and lenses. Leave the battery out for a few hours in case of a software bug. Dust Alert is greyed out with a manual focus lens. Optical Pre...

Re:Auto Focus
The switch was on AF on the lens and the camera. I have had a go at cleaning the contacts and it seems to be working ok. Thanks very much for the suggestions Sandy

Focusing Screen Dust!
Hi I noticed earlier a rather annoying dust spec on my focusing screen. After some ill-advised self attempts at cleaning it with air blowers and lens cleaning brushes, I am now left with a lot more dust there which is really annoying. Obviously I appreciate that it won't show up on any images but I ...

Focusing Screen Dust!
I had the same problem not so long ago, but dust had got into the mirror box as well, so I used a Green clean mini vac, I know they are meant for sensors, but if you remove the sensor pad and use the hose it works great.

Focusing Screen Dust!
It didn't on mine, but you don't need to touch the mirror just hover over it doing gentle movements. It worked great on mine. Plus it works great for doing general cleaning of the lenses e.c.t..

colour check
My Epson gives a purple cast when the heads need cleaning - run the cleaning utility on the printer and try it again.

K20D Banding Problem. Help Please
Yupp, very similar to what I had. The service changed the sensor, if I remember correctly. It did help a lot to rectify the problem, though I had a re-occurrence in a shot recently. The service was pretty quick, so it really is worth it. Good luck, Prieni

K20D Banding Problem. Help Please
I sent it back once, together with a printout of the forum discussion here which lead mostly to sensor replacements and lots of samples. Slightly awkward for me as I live in France so I have to find someone to take it back to the UK then to Pentax then back to someone in UK then back to me. Can t...

clogging issue with a epson R1800
I have an R800 - the A4 version of the R1800. Mine clogs frequently too. Big disappointment. I got some cartridges prefilled with cleaning fluid (can't remember where from). They helped a bit, but didn't completely clear the blockages.

clogging issue with a epson R1800
My experience with Epson printers (i'm on my 4th) currently using a 1400 for prints and my old R300 with cheapo CISS for general stuff (till the ink runs out:D) Anyway, I had lots of trouble with the first two (cant remember the models) then a guy at a computer fair where I picked up my cartridge...

Dirty Sensor - Glasgow help?
Ok, it is the first time that I have a problem with dust on the sensor. I have not kit to clean it, but no money to buy one or give it to professional cleaning as well. My idea was that maybe there is a member of this forum who has one of these little blowers or however you call it and knows how to ...

Dirty Sensor - Glasgow help?
Sorry I'm not near Glasgow. A blower can be bought cheaply from any camera shop or online. The "Rocket Blower" is very good, but any large blower should do. Blowing doesn't always work, but it is cheap! To prevent too much dust blowing about elsewhere in the camera, place the blower tip pretty...
