Try running a gentle stream of warm water over just the head that prints and with your finger gently , very gently rubbing to get rid of all the accumulation of dry ink. Then once it completely dry connect the print head back.Then put a drop of isoprophyl alcohol on the part of the cartridge that makes contact with the printhead.

    Printhead is the one that is where your cartridges are having contact when it print, that's the rectangular shape there , in order for you to clean it is to remove it from the printer.

    How do I do this? Thanks.

    Lift the gray lever up and remove the cartridges, look just below the gray lever and you will see two rounded protrusions inside towards the rear of the black box, grasp these protrusions with your thumbs and forefingers and gently pull toward you, there may be some resistance but pull smoothly do not force, then print head will come out.

  • kimnoble Aug 08, 2010

    I have removed the black box. There is ink on the inside and underneath. Which bit do I clean? Thanks.

    and with your finger gently , very gently rubbing to get rid of all
    the accumulation of dry ink. Then once it completely dry connect the
    print head back.

  • kimnoble Aug 08, 2010

    So sorry, but what do you mean "just the head that prints"? They all print, just not very well. Is there any part I shouldn't get the water on? Thanks again.

  • Mark Gil
    Mark Gil Aug 08, 2010

    Just clean all the ink remains on that part with warm water then dry it then put it back in.

PRINTER COLOR PROBLEMS


o.k. I can give you a few tips that may be of assistance.

you need to run a printer alignment page like you do when you put in new cartridges.

unplug your printer plug it back in.
open door and take out print ink cartridges.
put them back in and then close the door.

It should now prompt you to do a test alignment page.

Also, Another thing to try is to hit file, top left of page, hit print, click properties. color tab.

make sure you are printing high quality on chose different color management options.

FINALLY TRY THIS:

When Printing Becomes Faint or Colors are Incorrect

When printing becomes faint or colors are incorrect, even if ink remains in
the ink tanks, the print head nozzles are probably clogged. Follow the
procedures below to maintain the print head.
Important Before maintaining the print head, check the following;
􀁺 Open the front cover and make sure that the ink tank
contains ink. If it is out of ink, replace it.
􀁺 Ensure that all the orange tape of the ink tank has been
peeled off.
􀁺 Press "PUSH" on the ink tank and ensure that the ink tank
is installed securely.
􀁺 Increase the Print Quality setting in the printer driver
-----------------------------------------------------------------------------------
Printing the Nozzle Check Pattern
Print the nozzle check pattern to determine whether the ink ejects properly from the print
head nozzles, and to verify print head alignment. Use this function when printed results are
blurred or the color is incorrect.
1 With the printer on, load a sheet of Letter-sized paper in the printer.
2 Open the Printer Properties dialog box.
See "Opening the Printer Properties Dialog Box Directly from the Start Menu" on
page 25.
3 Print the Nozzle Check Pattern.
(3) When the confirmation message is displayed, click OK.
When the confirmation message is displayed after the nozzle check pattern has
been printed, click OK.
See "Examining the Nozzle Check Pattern" on page 52.
Note Nozzle check pattern printing can be executed also from the printer
itself. With the printer on, load a sheet of Letter-sized paper in the
printer. Hold the RESUME/CANCEL button until the POWER lamp flashes
--------------------------------------------------------------------------------------
Print Head Cleaning
Clean the print head if you suspect that the nozzles might be clogged. Cleaning the print
head consumes ink, so perform print head cleaning only when necessary.
The print head can be cleaned also from the printer itself. With the printer on, load a sheet
of Letter-sized paper in the printer. Hold the RESUME/CANCEL button until the POWER lamp
flashes once.
1 Ensure that the printer is on.
2 Open the Printer Properties dialog box.
See "Opening the Printer Properties Dialog Box Directly from the Start Menu" on
page 25.
3 Start Print Head Cleaning.
(1) Click the Maintenance tab.
(2) Click Cleaning.
(3) Select the print head to be
cleaned.
(4) Click Execute.
-------------------------------------------------------------------------------------------
Print Head Deep Cleaning
If print quality does not improve by standard print head cleaning, try performing print head
deep cleaning, which is a more powerful process. Print head deep cleaning consumes ink,
so perform this procedure only when necessary.
1 Ensure that the printer is on.
2 Open the Printer Properties dialog box.
See "Opening the Printer Properties Dialog Box Directly from the Start Menu" on
page 25.
3 Start Print Head Deep Cleaning.
(1) Click the Maintenance tab.
(2) Click Deep Cleaning.
(3) Select the print head to be
deeply cleaned.
(4) Click Execute
-------------------------------------------------------------------------------------------
Aligning the Print Head
This operation must be carried out when using the printer for the first time. Aligning the
print head positions allows you to print without shifts in the color registration.
Print head alignment is performed either automatically or manually. This section deals with
automatic print head alignment only.
1 With the printer on, load a sheet of Letter-sized paper in the printer.
2 Open the Printer Properties dialog box.
See "Opening the Printer Properties Dialog Box Directly from the Start Menu" on
page 25.
3 Print the pattern.
(1) Click the Maintenance tab.
(2) Click Print Head Alignment.
(3) Check that paper is loaded in the
printer and click OK. If a message
warning you not to perform other
operations appears, click OK.
It takes about one minute to start

My Canon won't clean its print heads


Hi,

Have you tried power cycling the printer?

Photos print with a faint 'pinstripe' effect


that could be head alignment (most noticible on low quality settings .. there is a procedure for aligning the heads ... or it could be clogged nozzles
to check these things start to print something
then select preferences .. then maintainence then
you have a choice .. nozzle check should be done first .. if all nozzles are working then go to "head alignment" and follow instructions there .. if some nozzles are not working then run the "cleaning" utility . sometimes it needs to do that several times .. if you cant get all nozzles working then you can try "deep cleaning" that uses lots of ink so you dont want to do that often ... if that doesnt work then you need new heads .. the heads in many pixma printers are easily replacable but costly ..
if all the nozzles are working and head alignment was done but you still have faint lines then try "high quality mode" .. in that mode you should not see any lines ..

Remove the cartridge. Take a paper towel and dampen it. Place the towel in the microwave and get it really hot. Draw the cartridge head over it 7 to 10 times until ink starts to flow. Now, take a dry paper towel and draw the head over it the same amount of times to make sure it is dry.

  1. In either COPY, PHOTO, or FILM menu screen, press <Menu> button.
  2. Press the left or right arrow to select [Maintenance/Settings], then press <OK>.

The print head alignment can be performed either automatically or manually.
If the automatic print head alignment does not resolve the problem, perform the print head alignment manually.

Canon iP90 stopped printing in BLACK


hi... it might be that you need some time to let the ink absorb into the pads in the print heads ... this can take between a few hours and a day... Must be frustrating to deep clean three times and just seem that you are wasting ink cartridges, my "solution" would be to give it time or possibly clean the print heads manually.. hope it will solve it out..

thank u!!
