Won't print I just refilled my black ink tank. Now my MP830 won't print. Is there someething I'm doing wron?

The small black ink is only used for printing photos and must be used in addition to the large one. If the large one is empty, it will not work.

your black ink cartridge got bad sprayer nozzles now you gotta replace it
and why the other color one is not bad yet cus printer as will known will depend on black ink far more so the black cartridge is heated up more times

You have to refill both.

Hi there!
In order for you to print you need to refill your cyan ink cartridge. Even if you just want to print black and white.

Replacing the five ink tanks (cyan, yellow, magenta, black dye, and black pigment) is a simple task. The top of the printer flips up to reveal the ink tanks and the printheads, and by flipping a lever, you can pull out each tank individually. Being able to replace individual tanks is a boon, as you won't waste colors you use less frequently. Also, you won't need separate photo ink to print photos, which we appreciate. Canon ships the Pixma MP830 with full ink tanks. Replacement color and dye-based black ink tanks cost $14.25 apiece, while the pigment-based black ink tank costs $16.25. Canon estimates the cost per page for both black text and color text to be an inexpensive 2 cents.

if that is removable try some other cartridge

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.

Looks like Fillserv.com has a chip resetter for the CLI8 color cartridges, but I don't know if that unit will reset the big black PGBK cartridge in the MP830.

I don't recommend refilling your cartridges.If if is not done properly the will leak and create a mess in the machine. I would always recommend new manufactures cartridges or a reputable re manufacturer

Hello, I found this in a repair manual for the MP830. summery is to press and hold the stop/reset button for 5 or more seconds. I copied the info from the manual too. The remaining ink amount unknown. [1683] (Applicable ink tank icon) The remaining level of the following ink cannot be correctly detected. An ink tank which has once been empty is installed. Replace the applicable ink tank with a new one. Printing with a once-empty or refilled ink tank can damage the print head. If printing is continued without replacing the refilled ink tank, press the Stop/Reset button for 5 sec. or longer to record the use of a refilled ink tank. Note: After the above operation, the function to detect the remaining ink amount is disabled.
