What is the amount of magnetic Powder to be developed in the Fuser Section?


None. It is electrostatic attraction.
It varies from each type of laser printer.
Most printers will specify a total number of pages printed from a laser toner cartridge rather than give an actual amount of toner per page. Which I feel would be more likely to be an average value.
Due to the amount of toner being used per page varying on the number of actual pixels that are required - a black dot or a color dot. If a colour dot is required Three toner colors may be involved to get the color required. Where there is a white dot no toner is required.
It really depends on what image is being rendered onto the paper on each different page image print onto the paper.
Color photos use more toner as more of the page is color than when using black and white !

I have used last 4 year canon 2900B printer. How to set 300 dpi printing resoluation


Canon PIXMA Manuals MG2900 series Resolution
Resolution The data in the image you have scanned is a collection of dots carrying information about brightness and color. The density of these dots is called "resolution", and resolution will determine the amount of detail your image contains. The unit of resolution is dots per inch (dpi). Dpi is the number of dots per inch (2.5 cm). The higher the resolution (value), the more detail in your image; the lower the resolution (value), the less detail.

How to Set the Resolution You can set the resolution in Resolution on the (Scanning from a Computer) tab of the Settings dialog.
Appropriate Resolution Settings Set the resolution according to the use of the scanned image.
Item Type Use Color Mode Appropriate Resolution Color photo Copying
(Printing) Color 300 dpi Creating a postcard Color 300 dpi Saving to a computer Color 300 dpi Using on a website or attaching to e-mail Color 150 dpi Black and white photo Saving to a computer Grayscale 300 dpi Using on a website or attaching to e-mail Grayscale 150 dpi Text document (document or magazine) Copying Color, Grayscale, or Black and White 300 dpi Attaching to e-mail Color, Grayscale, or Black and White 150 dpi Scanning text using OCR Color or Grayscale 300 dpi Important
  • If you double the resolution, the data size of the scanned image quadruples. If the file is too large, the processing speed will slow down significantly, and you will experience inconvenience such as lack of memory. Set the minimum required resolution according to the use of the image.
Note
  • When you will be printing the scanned image by enlarging it, scan by setting a higher resolution than the recommended one above.

How do you clean the dust out of the projector, there are particles that look like small white stars on the black areas and black stars on the white areas. Is this dust?


If you focus the image on a screen up close to the projector and notice small rectangular black and white spots, then you have pixel failures.

My hitachi cpx 443 lcd projector recently has been projecting blue dots everywhere on the screen, how can I fix this or what is the problem?


How defined are the dots? Is each blue dot limited to the size of a pixel? I suggest you create a 3 slide image in powerpoint ..one slide completely blue, 1 red and one green. then project each image in turn and note what happens with the blue dot. My first thoughts are you have some pixels that are locked. Once that happens if are pretty much stuck with them. Optical it is impossible for a dust on the lens etc to cause them as if the picture is in focus at the screen the dust is way out of the depth of the field, sometimes you can focus the projector so that the point of focus is the lens surface but then the actual content will be way out of focus...none of which has anything to do with your blue dots.

Black screen white dots


This is likely due to Hardware Failure. Your GPU (Graphics Processing Unit) has likely overheated to the extent of artifacting which is when the device begins to have trouble rendering objects and images and crashes constantly. The only viable solution is to send it in if you still have warranty, Otherwise, you'll have to either buy a new Xbox 360 or send it in for repairs from microsoft.

Hope this helps.

Plasma tv has little red dots in the black


This problem (known as sparkles) can be cured by adjusting the ramp control on the Y-Sustain board. If this does not cure the dots then there is a software remedy for the control board which an LG repair centre could fix. Failing that a replacement board is required. The orbitor & whitewash are like screen savers to help to prevent a screen burn from a permanently displayed image.

Black dot.


Ensure focusing is spot on. if your image is a black dot surrounded by white light (like a doughnut) then your not in focus. Look at making a Hartmann Mask (really easy, just google for it), which fits over the front lens. It has 2 or more holes in it,this means when you look through the eye piece you will see double images, adjust focus until the images merge into one (if the images go further apart turn the focuser the other way), when they are merged remove the mask and presto you should be in optimum focus. Always remember telescopes are very sensitive and focussing requires delicate adjustments.
