My Canon BJC S300 Printer isn't printing black ink, it comes up blank, but it is printing colour. I have changed the black cartridge but it is still doing the same thing?

Most probably is PRINT HEAD faulty.

you need a new printing head

clean the head and see what happen

First you need to ensure that this is not a driver problem, by reinstalling drivers and testing the printer on a different computer.

Also ensure that ink cartridges are OK, try replacement inks.

If the problem is not a software problem, and the printer is recognised by computer, and the printout is coming as a blank or faded page, then you usually have a faulty or clogged printhead.

Try first performing print head cleaning procedure from printer tools, that may not fix the problem, but do the cleaning a couple of times, just in case.

If the print head is clogged, that can be fixed soaking the print head in isopropyl alcohol overnight.

If still no luck, then the printhead must be replaced, here is the part: Canon MULTI-PASS F-80 Print Head $61.00

Nope. You can use Cyan, Magenta and Yellow as well as Black.

You can purchase Canon cartridges directly from Canon here. The BC-10 is a cartridge that prints with black ink only. The BCI-10 is the replacement ink tank for this cartridge (a new cartridge comes complete with an ink tank). The BC-11e is a cartridge that prints both black and color, and has two ink tanks, the BCI-11 black and BCI-11 color. A new BC-11e cartridge comes complete with two new ink tanks.

is there an detachable print head?

Have you tried changing the green carrier? That solved my problems with no ink.

I have had a similar problem to this: I have had a BJC 80 for nearly 5 years and carried it around with my laptop using Win 98 and a par - par cable. It worked beautifully and successfully - so much so that when i saw a number of ink tanks going at very cheap volume prices in PC World i picked up a lot of them. Changing to an XP meant that i had to keep on using the par to par cable via a docking station but prevented my use of it with my new laptop - so when i brought it out of retirement it gave the blank printing problems yoiu described. By checking some error messages that it expected a black cartridge (which is what was installed) i found that inthe setup the software indicated it defaulted to colour cartridges. By changing this on the computer, it still printed blank pages but by changing the cartridge to colour it sprang into life when the set up asked for colour. I tried 2 other print heads which i had (3-4 years old) but still blank paper when printing to a black cartridge. I am now awaiting a new black print head carrier to see if it makes a difference. When trying with my laptop using XP and a par - usb cable it does not work at all. I have removed the sware driver for the Canon 80 and manually installed the one for the Canon 85 but no luck in printing to par - usb at this time

I had this problem too. It turned out there was old dry ink in there clogging up the printerhead and it was fixed after I ran the cleaning programme several times. However I can't for the lifeof me remember how to do that now. I know I found it online but it has since vanished. Maybe check your manual?
