3eBk will not print. Canon MP780

Replacing the printhead may work, but it could be a problem with the cleaning assembly. Take out the 3ebk and run a cleaning, if the ink goes away on the pad where the ink cart. goes, then clean assy. is OK, and you need a new printhead.

Picked up a Canon S450 - nice printer, but....

Keep running the cleaning cycle. You may have to run 20X's to break the clog. And I would not perform any of the "maneuvers" you mentioned. Alcohol will turn the plastic to mush.

Prints black

Remove the print head, inks come out first. then lift the arm on the right of the head , it lifts out , never touch the gold pads on the back be very carful of the bottom print head. don't let cotton or tissue clog or get in the very fine print head nozels. so dont rub hard be very gentle let the alcohol do its job. soak at least 5 min.
clean the head with alcohol, let it sit on a soaked clean cloth saturated with 96% isoprople. ink will flow out on to the cloth its
ok put fresh full inks back in and deep clean right away and all should be well

Black lines running through certain lines of printed documents

Hi, ok your ink well is clogged (the stuff the ink cartridges fit in) remove all the ink tanks, then remove the inkwell by pulling the lever to the right. In a dish pour some rubbing alcohol and tel the ink jets soak a bit. pour some alcohol over the nossles(where the ink sits to send the ink through) and let it soak a bit more. Use a straw and cover the jets then blow, this will force the bad ink out clear the jets. Blot it dry then replace. blot each inktank before replacing them to insure the ink is running out. A couple of deep ink cleanings and you will be set.

If this fails you may have to replace the ink well and the cartridges (order new ones from canon) But cleaning it should work, try at least 3 times before deciding to buy a new one.

My Canon S750 Bubble Jet Printer does not print with black ink. It seems to print all other colors though.

Replace and install the black ink cartridge with this Black Ink Tank BCI-3eBK Ifyou have done this and is still missing the black ink on print, clean the print heads. 1. Right-click the printer icon, and then select 'Properties'.
2. Click the 'Maintenance' tab, and then click 'Deep Cleaning'. 3. Read the message displayed, and then click 'OK'. The power lamp blinks and print head deep cleaning starts. (Do not perform any other operations until print head deep cleaning is complete. Print head deep cleaning takes about 1 minute.)

That should most likely work. If deep cleaning did not help, you may need to replace the print head.

I am having problems getting my Printer to print text. It prints graphics just fine but it will not print text at all. I have tried cleaning and deep cleaning the Black 3eBK nozzle but this has not...

It's a print-head problem, the black nozzles are clogged out... sorry there is no remedy for this kind of problem..

But, try to ****-in air out from the print head's by using a syringe,
moz-screenshot.jpgno needle, on to the black ink tube, not the actual picture but I hope you got the idea. Then try cleaning again and a print test, keep doing this several times, but it would waste a lot of ink.

Hope this helps.

Hi Blackburn,

Get you some rubbing alcohol and Q-tips. Disconnect the power from the printer and remove the Ink Cartridges. Using the q-tips and soak them with the alcohol. Clean the electrical connections in each of the cartridge ports. You might go through several Q-tips before geting them cleaned up good. If necessary use Finger nail polish remover instead of Alcohol to get any contaminants off of the connections. Test a site with the fingernail polish remover first before dabbing it all over. I am afraid that it may eat up the electrical connections.
