Full of ink won't print - Canon PIXMA MP520 InkJet Printer

I had a Epson printer that would not print or even allow me to use the scanner because the colored ink was out. Even though I had full black ink, it still would not let me print until i replaced the colored ink.

Uncommon faults are with the electronic drivers in the printer system that drive and control the printer cartridges. This is providing the cartridges are proven to not be defective. Also, jammed nozzles will prevent printing.

Make sure your software is not set to print in monochrome (B&W) only .

ck it carefully

TRY CLEANING THE INK CARTRIDGE. If it doesnt work, go to service center with the printer.

Maybe your cartridges are not out of ink. Try it with another game cartridge kit...

here's a solution i came across when dealing with the same problem. apparently the printer expects all of the cartridges to be full and has a sensor to make sure they are even when only printing black. hope this helps!

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.

CL41, this is the one you are using for your cartridge.

Did you change your cartridge with brand new one or refilled one??

If you did with refilled one, the ink level won't go back with full.

This is the method how printer measures the ink level.

1. Each cartridge has a serial number.
2. As soon as installation in printer, printer recognizes the cartridge by serial #.
3. And the printer starts to count the printing document.
4. After reaching certain print counting, the ink level will show "low ink"

So my answer is even if you refilled your cartridge, the ink level won't change,
since printer cannot weight the cartridge or.....some other technology to measure each color ink level.

Thanks.

Use the software that was installed when you installed your printer to clean your print heads.

remove print head assembly. clean off.
print head not on cartridge.
