Replaced ink cartridges, printer goes through all the motions, but paper comes out blank. I have done all the maintenance steps. What gives?

Cannon ink cartridges go into a print head. This is normally a removable box the ink cartridge sits in.

First remove the head and the cartridges from it. Now try this to clean the old ink off the print head, rub/soak the print head in alcohol. Make sure the print head is complete dry and place the ink back in it and return to the printer. Try to print a page, if you have the same results you need to replace the print head.

Ink Absorber Full on Canon Printers

When you see the error "Ink absorber nearly full" or "ink absorber full" you
really need a shop to replace the ink absorber. The error is generated by firmware in the printer or multi-function that counts the number of prints, power cycles, and cleaning operations. It is not a sensor or gauge inside to be reset. The absorbers are thick pads covering the bottom of the print engine and all waste ink from the purge assembly is directed through channels and tubes to these absorbers. You should never reset the error code without fresh absorbers installed as the ink can fill inside and ruin the printer or damage the furniture the printer sits on. The absorbers are fairly cheap, from $10.00 to about $20.00 and after changing the pads the Canon repair person will enter the service mode and reset the counter. This operation is well worth the expense as a good technician will clean and lubricate the printer at the same time ensuring you of longer trouble-free printing.

How to unclog a clogged print head on the Canon...

Using a cotton swap dip into some plain water and then drop a few drops of water onto the outlet of the ink cartridge [you will have to remove the ink cartridge and turn it upside down].

Also while the ink cartridge is still removed, drop a few drops of water onto the inlet orifice into which the ink goes. The orifice of the ink cartridge sits right on top of the inlet to the print head when the ink cartridge is fully installed.

After putting the water drops onto the ink cartridge and onto the inlet orifice of the print head, I did the 'clean' procedure as listed in the "Canon PIXMA iP4000 Properties" of the program on my PC. Then I did the deep clean procedure. After that I printed the print pattern and found that this technique worked quite well -- since before I had tried isopropyl alcohol which didn't work to unclogged these print heads.

When I had the blue print head get clogged [on my Canon iP4000 Pixma printer] and I tried this method. It worked immediately.

I hope it works for you too.

God be with you!

Canon i9900 wont print, light keeps flashing green to yellow

Good Day,
Have you tried software update? According to this article,, it says Canon has updated it's drivers via Software Update.
f possible, spray some Windex in the heads and let it sit for, oh, 10-15 minutes. Then try to print. Any dried ink guck will be dissolved by the Windex.

Canon i960 qill not put ink on paper

I called Canon. I also had green 1 flash and amber 1flash everytime I turned on the printer. That right there indicates an elecrical problem. The flashes mean it needs serviced and with it not printing now means it's not wirth fixing, out of warranty. Canon did offer a code for reduced price new or referbished print from them.

Horrible grinding noise

The problem sounds like a broken or stripped gear in the printer. If the unit is under warranty I would contact the authorized repair station for that printer in your local area.
