Soft brush would be fine to clean hairs from mirror as blowing air will push hairs inside camera.

What areas of the Regency wood stove do I clean so that the fan blows stronger?


Many times, the fan blades themselves are the cause of lowered air flow. Think of the blades edges as though they were the cutting edges of a knife. You know a sharp knife cuts its products better than a dull knife....transfer that concept to airflow. A clean blade is sharper and slices through the air much better than a thick edged dirty and dull fan blade. I've seen extreme cases where the edges were 1/8" thick and the area between the blades nearly filled with lint, dust, dog hair and the like.

Service the blower blade first and while removed inspect the inside of the stove in front of the fan with a flashlight and small mirror. That will tell you if additional cleaning is required. If your motor is a cheap little 'shaded pole' motor, it could just be dragging and operating at a lower rpm than designed, delivering less airflow. If so, it may have to be replaced. There are no oil ports on most of these small motors.

Picture problems


Two things to look at from rear with back off: one is the inside of the screen and or the large mirror in rear of unit--do not touch mirror.

second is the unit has a small lens (2-3 inches) the points up towards the mirror---dust or such on it will cause this--it can be cleaned with a lens cloth.

If the mirror has this (uncommon) the entire front of set would have to be removed (screen units) and that is not real easy.

If lens and mirror and screen are ok problem is INSIDE the optical unit that the lens is part of---on rare occasions that can be cleaned out with compressed air.

without seeing a photo of what it looks like this is all I can suggest.

When using any lens, the view through the viewfinder has small spots like a liquid was sprayed on a optical component. What is this and how can I fix it?


It could be on the mirror, the underside of the focusing screen, or the back of the viewfinder. All three can be inspected visually.

The back of the viewfinder can be cleaned with any window cleaner. Don't spray any directly onto the camera, but rather onto a clean microfiber cloth and then wipe the viewfinder clean.

The mirror and the focusing screen are more delicate. First try a handheld blower (NOT canned compressed air). If that doesn't do it, try a camel-hair brush. Only then resort to wiping it with a clean dry microfiber cloth. Use common sense, and avoid scratching the mirror/focusing screen.

If it's on the inside, the camera will need professional cleaning.

My Nikon D90 has started to shoot images with what appears to be hair in lens, Switched lense to Macro and hair is still there It is always in varying shapes, so to speak But is ruining my images It...


If you switch lenses and the hair is still appearing on your pictures, it is quite possible you have an actual hair or thread or something located in the camera body in the way of the sensor. Remove your lens and visually examine the inside of the body for debris. Stay clear of the sensor and the mirror, but you can use tweezers to remove an obvious foreign object. You can also command your mirror to stay up and out of the way (see the camera setup menu "mirror lock up") for closer examination. It's best to use a bulb type squeeze blower to blow out debris from inside the camera. Do an internet search on "rocket air blower" and you'll see what I mean. Blowing air from your mouth can introduce moisture.

Mu laptop just shouts off at times without logging off


Usually when it shuts off like this it means it is overheating. That can be lack of airflow or the fan needs to be cleaned. You need to have the laptop sitting on a hard flat surface. If you use it on your laptop or a cloth covered table for instance it won't get as much cooling air and overheat.

If you don't use it this way then the problem is the fan or cooling system is full of dust or hair. If you have gas heat, pets, live where its dusty or the laptop is near the kitchen then it can take a few months at most before even a brand new laptop can begin to overheat. You can use a can of computer air such as dust off to blow in the air intake and exhaust. If you see just one small puff of dust and you will be surprised how small, then this should fix your overheating for a few months. If you don't feel comfortable doing this any computer shop can blow it out. If that doesn't fix it then the heating system is probably packed with hair or dust and the laptop needs to be disassembled and cleaned. This should cost about $50 and the can of canned air should be $4-$10.

Hair and particles on pictures-not on lens or mirror-on sensor


You must have dusty mirror box area. Here is what you should do. 1. Remove lens from the body. 2. Blow out any dust from the mirror box area using can duster (careful not to spew out liquid). 3. go to menu and select mirror up or ccd clean mode. You can also set at manual shutter speed "B" and hold up the mirror. 4. Blow out dusts over the CCD sensor (Do Not Use can air! If any liquid sprayed on CCD the cleaning gets worse) so use Hand-squeezee air bulb. You can purchase one from any camera stores.) 5. test shots and repeat. 6. If this procedure did not resolve the removal of the dust, you can purchase a cleaning solution package and try it. I do not recommend it becasue our techs get lots of cleaning requests from these package. Remember, if you are using these solution, 1. Never give any pressure to the screen, just tissuie touch pressure only. 2. move circular motion as you mouth blow the air as you move. complete the motion exiting through the corner of the screen. Did not work? send it to repair techinician! Our tech cleans it for $49. 24 hour turn around and also checks the camera too. Good Luck

A "hair" shows up in the corner of my pictures


Have you cleaned to sensor on the camera? The sensor is located behind the mirror. Be very careful . Read your manual on how to do this. Most camera store will clean the sensor for you for a price. You can do this on your own but be careful not to scratch the sensor.

Small hair in view finder


That camera has a removable focusing screen. Usually the object(hair) is sitting on top of the focusing screen so the screen has to be dropped down to remove it. There is a clip(frame) accessable from the mirror box that needs to be un-hooked. The frame swings down and usually the screen and a brass shim(s) comes down with it. If your careful and don't actually remove the frame, screen and shim it's pretty straight forward to gently blow the hair out. After removing the hair, gently swing the frame up and clip it back in.If the frame, screen and shim actually fall out it's tricky getting them back in correctly. The screen is also very soft and scratches easily so much care is needed. If you're uncomfortable trying to attempt this then take the MZ50 to a good repair shop. We do this service free and usually while you wait. Other shops may charge you a fee to do it. If the hair is behind the eyepiece then the top cover has to be removed to get the hair out. That is a totally different problem and the camera will need to be repaired. Since the hair dosen't affect the image on the film, you may just want to live with it or have it removed when something else needs to be done when the camera has to be disassembled anyway. Hope this helps.

Need to clean mirror or lens


The particel or hair is probably on the IR filter glass that sits over the sensor. You could try puting the shutter on bulb. If you then remove the lens and hold the shutter release you will be able to see the filter glass and possibly be able to remove the particle with a blst of compressed air. Do this in a cleanish room or you will make things worse.
