If the nozzle check pattern shows adequate ink, but the printer doesn`t print color, clean the printhead. After that, print a nozzle check pattern. After performing printhead cleaning, perform a printhead deep cleaning. If still, the problem persists, switch off your printer and do the deep cleaning after a day.
It`s usually because the printhead inside your printer is clogged or dried out. Like with most printers, Canon printheads can clog due to ink or dust drying up and collecting in the nozzle.
A printer printing lines on the page are normally caused by a blocked, dirty, or damaged print head. Blocked ink cartridge nozzles, or not removing protective seals correctly when you installed a new ink cartridge can also cause missing lines of print.
If your printouts have incorrect colors, try these solutions: Make sure the paper type setting matches the paper you loaded. Make sure the Black/Grayscale or Grayscale setting is not selected in your printer software. Run a nozzle check to see if any of the print head nozzles are clogged.
First, check your printer settings on the file or picture your trying to print. If your page is setup to print in “grayscale” it will only print in black and white. Change the setting to “default” so it will print in color. If your settings look good from the start, the cartridge may just need to be primed.
Printers may produce poor quality printing if they are exposed to too much heat. Don`t place your printers in a high-temperature area or near other devices that produce excess heat. In addition, keep them away from windows, where heat and humidity can be high.
If your printouts are blurry or smeared, try these solutions: Make sure your paper is not damp, curled, old, or loaded incorrectly in your product. Use a support sheet with special paper, or load special paper one sheet at a time. Make sure your paper meets the specifications for your product.
Dirty or misaligned print heads

Your printer may be printing fuzzy, blurry, or other faint text because of dirty print heads. All modern printers have a self-cleaning mode, which cleans the print heads, and additional internal equipment used in the printing process.

Often, when there are lines or shading on your print job, the print cartridge could be the reason. When the print cartridge is not being effectively cleaned off, it creates streaks or shading on the document.
Why is my printer printing yellow not red? It is most likely that your image is yellow where you were expecting it to be red and you may also notice that blue parts of the image appear turquoise instead. Both of these effects are caused by a lack of magenta ink/toner on your prints.
The first step in printer calibration is to calibrate your monitor. Then, make sure you use the correct printer driver for your printer. Within the printer driver are controls for fine-tuning the overall appearance of color from your printer. Depending on your needs, this may be sufficient to get the color you want.

ANSWER : Epson printers don’t like to sit unused. The printheads will clog with dried ink. Your only hope is to use a Printhead cleaning kit.
