Color printing My printer is not printing color correctly. When checking in Maintenance, there is no cyan on the second line showing at all. The rest of the colors are lined.

The printhead has either become too clogged to flush out with with the internal cleaning operation (which uses a LOT of ink), OR, the nozzles are not firing. If after several cleaning operations there is still no significant improvement, you will need to replace the print head. I see this frequently with Canon and Epson, and Brother inkjet printers. Usually, it is due to leaving the printer idle for too long, or removing a cartridge and not replacing it right away. The air gets to the residual puddle of ink in the head and dries it. Also, using compatible or refilled cartridges can risk clogging because the ink formula is not an exact copy of the genuine Canon formula. I recommend using only new Canon carts for replacement, and do not mix Canon with non-Canon carts.

You can find the replacement print head by Google searching "MP830 print head". Prices can vary from around $70 - $90. Changing it out is fairly simple. You only need to lift a lever that holds the head in place. Make certain that it is squarely seated, and then run a few pages of a color document, or do a couple of standard cleaning operations to "prime" the head.

Make sure the hed is NEW and not used or "refurbished". Here is one source on eBay that sells it for $78.00:
