Why is a yellow light flashing on my canon mg2520 printer

I have the same problem and I tried to clean the cartridges. No result.

Hi! I've got same problem. Canon userguide says that 5 flashes means the print head is not installed/not properly installed, or it is defective.Not yet sorted problem out - new print-heads are expensive!

SOURCE: Canon S520 printer flashes the yellow light 8 times.

This will only slightly help...my cannon printers waste tank was never actually full, there is just a built in counter system that figures when it might be getting to that point.

To reset the count before you cant print at all because of it:

A) Turn the printer off.

B) Press and hold RESUME, then press and hold the POWER button.

C) Release the RESUME button, Next press and release the RESUME button twice more while continuing to hold the POWER button). The printer's carriage will move a around a bit.

If by some miracle we did that correctly on the first try, you are now in "Service Mode".

D) Press the RESUME button 4 times (clear waste ink counter function). The light will change color with each key press. Press the POWER button to commit the change, and return to the top of the function selection menu. Press the POWER button again to restart the printer.

Now for to check the waste pad...(excerpt from http://www.neilslade.com/Papers/inkjetstuff11.html)

• Figure out how to open the printer by removing the side and inside top plastic panels. Just look at the thing and use your brain. Its all pressure clipped in place, no screws (at least on the S900 and similar models, probably still the same on this years models.) Look for slots and triangles on the 960.
  
• On the i960 you'll have to remove the power buttons assembly on the front- take out the two screws, unplug the internal white electro connector plug CAREFULLY, then you can undo the last clip that holds the top in place.
  
• No need to remove the ink cartridges in this process- so don't. The mechanism is held down in place in the case by two screws at the very bottom on the outside bottom of the metal chassis inside. Remove these screws then lift up the mechanism. It should lift out fairly easily, but remain attached by wires-- just place it on the top edge of the case.
  
• You'll see the blackened (from waste ink) felt pads on the bottom. WEAR GLOVES-- this is skin indelible ink, the only thing that will get it off your hands is CLOROX. Period. There are two skinny pads that sit on top of a larger pad. Note how they fit together.
  
• Lift the pads out and rinse out thorough in a sink until very little or no ink comes out. There's no need to use chemical or soap cleaners, just use plain water from the tap and the spray nozzle. Keep rinsing and squeezing the pads, but don't twist them like a towel, squeeze and fold in half however to really get the ink out.
  
• Lay flat in the sun for a few hours to dry. Use a hairdryer to get the last bit of moisture out then replace in the printer, and put everything back together.
  
• RESET the printer electronics, so you won't get the stupid "waste ink tank full" message any more. Do an online web search if this doesn't work for your model, although this works (or slight variations0 for many, including the 8200, the S800, and S900, and the i-series like the i869, i950, i960, etc.Two main buttons on the top of the printer- Power and the Resume:

I caved in and payed the Canon technician $10 for troubleshooting to find out that this code means there is a hardware failure if you are still getting the four flashing amber/orange lights on startup.

After visiting cartridge world I was informed that they have seen this numerous times before and are convinced the printers are rigged to fail. Essentially they told me that Canon created printers to die after a certain amount of use, which only makes sense considering my printer sat in the same spot for 5 years. How could have it suffered a hardware failure if it was never dropped, let alone moved.!?!?!

Their manufacturers manual says to replace your printer if you have this issue. Old printers, I was told, did not have motherboards, and since their invention it's become apparent that these companies have their hardware wired to fail after a certain time/amount of use. Typically people start to see the ink tank error, the printer head error/failure, and then the hard drive error/failure, which is EXACTLY what happened to me. All they want is for you to purchase new parts, pay for technical support, and pay ridiculous amounts to have parts replaced. It's that or get a 15% discount on a new model that probably costs upwards of $200.

Shame on Canon. I will never buy their products again. Save your money and get a laser printer where you can replace the hard drive in the printer if it "expires".
