Canon IP 90 clogged printhead nozzles. How to remove printhead?


Hi there,

To avoid drying of the Print Head and clogging of the nozzles, note the following.
*When you turn off the Machine
Follow the procedure below to turn off the machine.
1)Press the ON/OFF button to turn off the machine,
2) Confirm that the POWER lamp has gone out.
This takes a few seconds or as long as 20 seconds.
3) Unplug the power cord from the wall outlet.
If you are using a power outlet strip, you can switch off instead.
When you press the ON/OFF button to turn off the machine, the machine automatically puts a protective cap on the Print Head to prevent the ink from drying. If you remove the power cord or switch off the power outlet strip before the POWER lamp goes out, this capping will not be done properly, causing the Print Head to dry and clog.

* When You are not Using the Machine for a Long Time.
When you are not using the machine for a long time, print or copy in both black and white and in color or pertorm Print Head Cleaning, about once a month to prevent degradation of the Print Head.
Numerous nozzles are installed in the Print Head for high -precision printing. Just as the uncapped tip of a ballpoint pen or marker becomes dry and unusable if it is not used for a long period of time, the print nozzles becomes blocked by dried ink. Periodically printing or cleaning of the Print Head can prevent this blockage.
Note :
*If the printed area is traced with a highlight pen or paint-stick or stained with water or sweat, ink may blur depending in the paper.
*If the print head nozzles get clogged , printouts will become faint or particular colors will not be printed properly.

  2. Lift the scanning unit (printer cover) completely. (The print head will move to the replacement position.)

    CAUTION:

    b. Do not touch any metal parts.


  4. Press down on the ink tank until a click is heard, thereby making sure the ink tank is seated properly.

  5. Ensure that all the ink tanks are installed properly and the ink tank lamps light red.

    05sj00141_09_en.jpg

    Note:
    Ink Tank Lamp
    You can check the status of each ink tank according to the way its lamp flashes.
    • - On: The printer is ready to print.
    • - Slow flashing (at about three second interval): Ink is low. Prepare a new ink tank.
    • - Fast flashing (at about one second interval): Ink tank is empty, or the printer is not ready due to an error.
    • - Off: An error has occurred and the printer is not ready to print.
  6. Close the inner cover and the scanning unit (printer cover).

    Note:
    1. When closing the scanning unit (printer cover), be careful not to jam your finger.
    2. When starting printing next time, the print head cleaning launches automatically.

Will not print 6BK


Please see the Canon link below, and as Canon links return generic pages, type in "missing black print" (without quotes) or something of that nature. The results will include Reseat/remove printhead, among others. I have reproduced that content for you below, but I would also add that a number of folks have issues with black print cartridges, and it seems this is an issue that is fairly widespread, as one of the results is that your printer may need repair. If you have tried more than one cartridge with the same result, suggest consulting support if you don't think your usage justifies a new print head - especially if you are still under warranty.

I believe that he is reffering to the waste ink tank where the cartriges stop to the right when not being used. There are two small foam pads over there.
I cleaned mine by opening lid and have carriage run to the left, then I reach in with a q-tip and press down repeatly until q-tips are almost clean. You will need a flashlight to see waht you are doing.
