I replaced the used black cartridge on my canon mp750 and it has since stopped printing in black. Prior to this it was fine. Any ideas?

Its more then likely your purge unit hose is clogged.

If you can reach the purge units filters (thin porus thing that the printhead stops over when doing the cleaning) with a tweezers or long thin needle nose pliers. You will need a cup of hot water to dip the piece in once you remove it. let it float in the cup for a little bit while you take a q-tip and dab hot water onto the purge unit (the area where you removed the filter) turn the printer on and off a couple times til you see the purge unit **** the water down. Then replace the filter and and try to run a test print.

Dear Adrienne,First make sure that the black ink is not empty. If you are sure the black ink is full enough you need to check the print head condition. The print head may be clogged or faulty.
To fix the clogged print head,please perform the following step:
  • Print the nozzle check pattern, access the following menu on LCD: Menu>Maintenance>Nozzle Check. The good nozzle pattern should like below sample image.

10_5_2011_3_51_03_pm.jpg
  • If the print head nozzle missing some color (i.e Black) the perform print head cleaning: Menu>Maintenance>Cleaning. Then print the nozzle check pattern again. Note: you may repeat this step up to 3 times.
  • If the problem still remain,then you should perform Deep Cleaning: Menu>Maintenance>Deep Cleaning.
If you have perform the above steps but the problem still the same,please check whether the black nozzle missing partially or totally. The faulty Purge Unit (ink pump) may cause the same problem. I mean the purge unit does not work properly so the ink cannot flow. Good luck :)

My Canon won't clean its print heads


Hi,

Have you tried power cycling the printer?

Printer has worked perfectly since purchased, suddenly started printing only the black portions of a photo. Did a nozzle check which confirmed only black cartridge functioning. Deep cleaned all heads....


The print head is still probably still partially blocked. Cleaning/deep cleaning tries to clear the head by flushing ink through, doesn't always work but does use up your ink.

You can get print head cleaning kits, PC shops,ebay etc. Try one of those.

Here's a really useful ebay url. with some youtube links, if you run the second video down you should get a pretty good idea.
http://www.ebay.co.uk/itm/Printer-Print-Head-Printhead-Cleaning-kit-Epson-Canon-/130479422758?pt=UK_Computing_Printer_Paper_Accessories_ET&hash=item1e612dfd26

Here's a direct link :- http://www.printheadhospital.co.uk/quickshop/

You don't have to buy this one, there may be cheaper, have a shop around.

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

  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.

3e Black cartridge won't print


I'm not an expert but I go through a lot of ink.. I have found that even with new ink some of the tanks of ink aren't any good especially with compatible which i buy a lot of because it's a lot cheaper (ebay). With that ink I have gone through 10 cartridges in a row before finding one that worked correctly again (I mean out of 100+ cartridges hitting a run of 10 that where bad but the rest good.)

Also, a tech for epson once told me to hit deep clean 7 times in a row before a head check to clean their nozzles.. That has helped with my printer and at Fry's electronics, they have a cleaning solvent in kit, haven't tried it, but i have run alcohol through mine but I'm told that is very ******* the print head (dissolves the glue).

Hope that helped..
