Says the type of printhead is incorrect but has printed a few minutes ago fine and always has been ok. Help

Hi Daniel
remove all ink tanks then take out the printhead. If you don't know how to remove the p/h...there is a lever on side of the carriage. Lift it up and the p/h will come out. Wipe the electrical contacts (on back of p/h with damp tissue then polish with dry. Fit p/h and cartridges in, turn printer off/on. If error persists, try turning printer off/on couple of times.
If that doesn't fix the problem, the p/h is faulty and needs replacing.

good luck...

Clean the printhead
If your printed output is streaked or has any incorrect or missing colors, the printhead
might need to be cleaned.
This process uses ink to attempt to unclog and clean the nozzles in the printhead.
This might take a few minutes and will use one or more sheets of paper.
To clean the printhead from the control panel
1. Load letter, A4, or legal unused plain white paper into the main input tray.
2. Press Setup.
3. Press the down arrow button to highlight Tools, and then press OK.
4. Press the down arrow button to highlight Clean Printhead, and then press OK.
The product cleans the printhead.
5. Press any button to return to the Tools menu.
To clean the printhead from the Printer Toolbox
1. Load letter, A4, or legal unused plain white paper into the main input tray.
2. In the HP Solution Center, click Settings.
Work with ink cartridges 1513. In the Print Settings area, click Printer Toolbox.
NOTE: You can also open the Printer Toolbox from the Print Properties dialog
box. In the Print Properties dialog box, click the Features tab, and then click
Printer Services.
The Printer Toolbox appears.
4. Click the Device Services tab.
5. Click Clean Printhead.
6. Follow the prompts until you are satisfied with the quality of the output, and then click
Done.
There are two stages of cleaning. Each stage lasts about two minutes, uses one sheet
of paper, and uses an increasing amount of ink. After each stage, review the quality
of the printed page. You should only initiate the next phase of cleaning if the print
quality is poor.
If print quality still seems poor after you complete both stages of cleaning, try aligning
the printer. If print quality problems persist after cleaning and aligning, contact HP
support.

Try removing the printhead and cleaning the contacts on the back with metho. Works sometimes...but not always. Moving the installed printhead slightly in the cradle it sits in, can also "spark" it back to life.

hope this helps

There is always a reson. Try checking that the cartridge you installed is the correct one for your printer. Some refurbished also cause this problem as they have been recycled too many times.

Please rate my help++++Thanks for using FIXYA

The printhead always burns out the black first, it's the most used.You will need a new printhead QY6-0070-000, around $50.00

go into the printer properties and go to advance tab and do a realignment of the print head's as well as service

That happens when the printhead goes out, you'll need a new printhead,QY6-0075-000 around $50.00

It just means that the printhead is defective, All of the Canon machines say that when the printhead goes out.

Hi follow the instructions as above...
ie Remove inks and print head...

But instead...
Whilst Canon print head is out...

Use cotton wool and alcohol and clean electrical contacts on back of print head and where they make contact inside printer.

Then install print head and inks and test.

If it does not work you may need to replace print head.
Hope it helps!
Good Luck!

Ok i know this is kinda old, but i found a solution.

First to those people to state I found a solution from hp, cannon etc etc and not give out the direct link, or instructions, then whats the point fing posting????

This error happens when you install an oem cartridge onto your system. Or havent used it in a while, so the machine is somehow misfigured.

This solution is for canon mp800, simply switch off printer. HOLD stop/reset and press and HOLD on/off button. release stop/reset. Now press stop.reset twice. then release on/off button, press stop/reset 4 times, wait 20 seconds, press on/off button twice.

switch machine back on and the printer should find the cartridges.

This method maybe the same for your mp*** if not google RESET CANON PRINTER MP*** and you'll find the correct buttons to press.

here's a printer on reseting a bunch of canon printers http://tricks-collections.com/reset-printer-canon-mp140-mp160-mp180-mp210-mp220-mp460-mp470-mp500-mp510-mp530-mp600-mp610-mp800-mp820-mp810-mp830-mp960-mp970/

good luck.. and FU canon for adding you scamming chips into cartridges.
