Grainy image quality on my Phaser 7750


Try something, Send a job with 5 pages to it.
Shut the machine off as a page it halfway out of the exit area.. Open the machine and look at the jammed copies. Are they clear in the imaging unit areas but not upon exiting the machine?
If the image is clear around the drums and imaging unit, then the problem would be in the fuser. If the image is grainy and fuzzy in the image area, You could have a bad second BTR roller, the soft black roller on the left side door. One of the developer housings could be bad. You have to remove the imaging units and look in the opening with a flashlight to see if the developer housing brush is thick on the developer roll.
Could have a bad transfer belt or one of the color housings could be bad.
Less likely is a bad laser. But have you taken the wand that is on the front cover and cleaned the laser exposure slots?

Grainy printing down left side


Toner cartridges have the shortest life in the laser printer. So for every image quality issue try replacing that color that you see the defects in.

How to overcome Grainy photos on some in door shots with my Canon A710


The reason for this is that the auto scene function chooses which ISO (light sensitivity) is needed to have a fast enough shutter speed to capture a still image (instead of a ghosted image). There is no way to change this. You can switch modes to P and specify the ISO you want to use (100-200 will give you a clear, non-grainy image, 400+ will be grainy). To capture a still image in low light with a low ISO, you need to use a tripod. Hope this helps.

LP600 - Grainy picture, very poor quality


Single chip DLP projectors use a spinning color wheel between the lamp and the DMD (mirror chip) to produce colors. If the wheel rotation/synchronization is disturbed, colors will not be displayed correctly.
In my case it looks like the wheel became un-synchronized, probably because the projector was dusty/dirty inside (a light senor is used to detect the wheel position), resulting in a grainy, slightly flickering image.
I simply blew out the components with a can of 'Dust-off' and, using a small tool, rotated the color wheel by hand to make sue it wasn't rubbing or jammed.
I reassembled & started the projector and the image was back to normal.

Zooming with Olympus Stylus 820


Hey missy0528,
There are a few reasons your images might be grainy, one of which is your image quality is set to low. I would always have the camera set to the highest resolution possible, because you can always reduce the size of an image but you can never make it bigger. Another cause of grainy images in digital cameras is the sensitivity of the camera (ISO) is set to high. Since you are only seeing grainy images when you use the zoom the reason for the grainy images is most likely do to using the digital zoom. All a digital zoom does is crop the image much as you can do in some computer applications, and by doing this you greatly reduce your image quality. I would never use a digital zoom. Your camera has a 5x optical zoom and a 5.6x digital zoom. I would only use the optical zoom. I hope this helps!

Sincerely,
Allan
Go Ahead. Use Us.

My pictures display poor image quality on the screen or when you print them out.


PhotoPC 800 captures images in 24-bit color (16.7 million colors). Your pictures will not display maximum image quality if your monitor or computer's video controller doesn't support this color depth. You may need to upgrade your system to achieve the best possible image quality. If your pictures look better on the screen than when you print them out, you may need to upgrade your printer. An EPSON Stylus ink jet printer, for example, provides excellent image quality. If you used drag and drop to insert your pictures, they may appear grainy. Try importing them into your documents instead.

Additionally, if your pictures are taken in 1154 x 864 mode, try increasing your video resolution above 640 x 480. You may need to upgrade your system to achieve the best possible image quality.

Noisy or grainy images


When you press the “T” zoom button, the image in the viewfinder will become closer. However, since the D-435 uses a digital zoom, the lens doesn't physically zoom, it takes the existing image and enlarges your image using an electronic program. This can result in a “noisy” or “grainy” look to the image, which is normal when using the digital zoom.
