printer prob with black ink only

[Robinb]

Hi

I am having problems printing in black (greyscale). It prints one page OK
then, the black ink is interrupted by blank lines , then by the third page
it is not printing anything at all. For all printing soon after that,
nothing is printed. If I print in colour however, it works OK. I
have changed the ink, done all the maintenace (clean nozzle and test comes
out OK). The printer is about 4 years old. Canon.

Suggestions? Thank you

Robin

Printhead failure I am afraid. It cannot be the purge unit or you would
have
colour printing issues.
A new printhead will almost certainly fix it.

I'd have to agree with Tony... and as for why the first page is OK, it's
heating up, so by the time it gets to the second page, you get 'rubbish' and
then by the third page, it's so hot you get nothing at all. If you really
like the printer, there's no reason why you shouldn't get a replacement
printhead from somewhere like eBay and keep using it.

Model number might help.

Some Canon printers used two different black ink cartridges, one pigment
for text, the other black for photo and charts for use with color inks.

The top poster thinks he is a know it all but he really does not know how
the Canon printers work. If you do NOT duplex then the printer uses the
large black pigmented ink cart. If you duplex he will mix colors and some
of the photo black to produce black. You can tell by the blackness of the
print when you turn duplex off or turn it on.
