Canon PIXMA iP 3000: Suddenly, everything prints hot pink

Worn print head. And for what they charge for a stinking print head you can get a new printer for less with a warranty to boot!

prints everything in pink or magenta. Cannot get it to print in regular black.

Sounds like **** cartridges. there are so many bad or so called recycled cartridges about. If the work is important then buy originals. Play.com seem to be the cheapest.

There is no adjustment to printing coloured text. This is rather unusual. I feel you maybe using recycled cartridges and the magenta is not true magenta. I once bought a couple of so called magentas and they turned out to be orange!!

I refilled Canon cartridge CL-811. I filled all 3 colors. Magenta Cyan Yelloware flowing well,. Even if I wipe the cart on paper tissue, 3 colors are coming out (pink magenta and Yellow).but while printing yellow colour isnot printing,. Any idea how I can fix the problem?

I'm not really sure, but if I were you, Id work with all the cartridges. Moisten a lintless soft paper or tissue and gently wipe printhead of each cartridge. Be sure you 'seat" them carefully and securely. I think one or more cartridges is empty OR dry. See if this helps a bit.

Take the print head out of the machine and sit it in a saucer of very hot ( just off boil) water about 10mm deep for a minute. Take it out and sit in on a pad of paper towel to dry briefly before returning it and the cartridges into the machine. Give it a deep clean and try again. If still no good, the print head has probably had it.

The other week I had the black print head clog up, requiring daily nozzle deep cleaning [a normal 'ocassional' maintenance function]. Thought I needed a new Print head, so anything worth a try.
I loaded up an old black cartridge [I load all my own......always have] with Isopropyl Alcohol and ran deep clean on that cartridge a couple of times, then repeat printed [6 times] a page full of the number 8 in about half inch character size, to get the alcohol through the nozzles. then Deep cleaned again 3 times, to wash it through the print head.

I reloaded the normal ink filled cartridge and ran the '8' page again till I got good black output. It has now been working without problem, daily, for over a week. Clearly if it's a Magenta only problem, the cleaning as described above would be a bit different, as the magenta is one of 4 colour cartridges.
My printer does quite a lot of work, and was bought at least a couple of years ago, being used daily for alpha numeric and photo printing work. This was the first difficulty I experienced with it.
Hope the above might help.Ken

Check in your printer driver settings "advanced" section, and see what the presets are. if the RGB or CYMK settings have a slider, see if the magenta is set at 100%. If it has a slider, try it at 90%, 80%, etc until you have a less pinkish hue. You can then create a printer profile which will work with the photo paper you are using.

Different photo papers can cause hues like this.
Also, you can remove pink any unpleasant hues with most photo image editors through color correction.

It's possible that you have a contaminated cartridge...especially if it's a refilled tri-color cartridge.

maybe the print heads need cleaning?
