Sounds like it's in draft mode...

On the MP830 locate the "settings" button (top right of the cursor circle and left of the 1 key).

Press "settings"
This should give you the "Print Quality" settings page on the LED
Locate the 3rd field down which probably says "Fast", change this to "Standard"
Press the "settings" button again to register the change.

Also possible that your contrast is causing problems... Check to see where the red bar is in the gradient (white to black line) under the "Copies" field on the LED in copy mode. If it's way over to the left that would also explain some of the problem.

Pressing the right arrow key on the circle controller will increase contrast although I'm not sure if it will retain this setting.

Hope that helps.

My MP830 leaves white horizontal bands when printing black & white documents. Color printing seems fine. Pattern 'F' is missing on the print alignment page.


You need to continually clean and deep clean and realign the black until the results are acceptable. Try manual alignment if the auto does not work. Also clean around the exit hole of the black ink cartidge with a cotton bud and isoproyl alcohol.

Leaking Ink Cartridge


You need a shop to clean the extra ink that's coming up on the rollers and install a mylar strip to prevent that in the future. It's the waste ink being forced up thru the exit rollers and getting on the prints.

All of a sudden my Canon MP830 is printing only very light, unclear very light black lines on the chapter of my dissertation I am trying to print. All the ink tanks are full & I've done 2 deep...


Doesn't matter if the ink tanks are full. They may also have dry ink on headers. You could try to draw a black rectangle in MS Paintor any other software and try to print it at the best quality. You also could try to remove the black cartridge and see if it leave a ink stain on a absorbant paper (like a napkin). If does not leave a ink stain it means that the ink is dry.

If this is the case you may try to boil some water. When the water is boiled take it away from the fire and sink the cartridge into the boiled water and keep it there until the water cool down.

Black line down the center down the page


If it is a lazer printer a score on the photosensitive drum will leave a black line. Sometimes it is less grevious cace of an accumulation of ink leaving a line around the drum. This can happen when printing many dark background or full bleed copies. These drums are seensitive but can be carefully cleaned. Work away from direct strong light.

The printed pages with black is light and spotty.


Hello,
Try to run the "Clean Print Heads" utility. Sometimes it is called something else, but whenever your print quality degrades, this is a good program to run. If that doesn't work, then I would suggest replacing the print cartridge. Sometimes they go bad if they have not been used for a long time. Hope this helps!

Canon MP830 printing with interlacing shades of black


your printer cartridge or head unit ink channel (some of color or black ink channel) constipated, you may try:
1) if your ink cartridge is not new, take out the cartridge put the bottom surface touch cleaner liquid(special for ink printer) or water for 1 hr (you can see ink spread water), then set back and test. refill enough ink maybe necessary.
2) still trouble, you need clean print head ink channel to do same thing above, if your print head is separated from the cartridge.

You most likely have some ink residue on the pickup, feed, or registration rollers for the problem to be on the back of the page. Use a flashlight and a q-tip moistened with isopropyl alcohol to swab all of the rollers in the paper path and see where the higest concentration is. You could also try to LIGHTLY dampen a sheet of paper with alcohol and print a "Blank" page a few times with it then do the same with fresh paper.

Printing color copies


check to see which cartridge you put in, photo magenta cartridges DO NOT work in the MP830. sounds silly but we see it all the time.

check to see if the short vertical black bar next to the magenta pattern looks ok, not brown or gray or streaky. if it is you may need a professional head flush, take the whole printer in for service.

Dark strip down center of page when coping from tray


There is a small strip of glass on the left side directly under the edge of the scanner, About a half an inch wide. It has something on it.
May be very hard to see, use a strong glass cleaner or some alcohol and a regular piece of paper to clean it with.
