Canon i850 won't print black text
My Canon i850 won't print black text (but will print other colors) despite
having cleaned (soaked) the print head with ammonia and performed serveral deep cleanings. I performed a nozzle check, and the black grid (at the top) as well as solid black bars A and F did not print. However, black bars G, L and M did print. Unless patterns G, L and M are generated by different nozzles, it doesn't appear to a clogged nozzle. So I'm at a loss as to what to try next. Any suggestions? I'm rather dismayed that I'm having this problem as the printer is not that old (~ 6 months) and has not been used much. Thanks for any help. I appreciate it. Pat |

A friend has the same trouble. They happened to let the ink run completely dry is what caused the problem. Did you use generic inks or let the printer sit idle for a long long time? I'm just wondering how this came about. You may want to consider a cleaning method found on this page. http://216.219.159.185/clean.html |

I use my printer until it says low ink, then until it says that it's empty and I have to replace the cartridge. So far, trouble free printing. The i560 is a great printer. |

I originally thought it was a clog and spent some time cleaning the heads (using an ammonia solution). What confuses me about this is why, with the nozzle check, some of the black patterns print and others don't. If the black nozzles were clogged, wouldn't it effect all of the patterns? Thanks again. -Pat |

The i560 is a great printer. What I meant by "completely dry" was the sponge itsself was totally dried out. All warnings were ignored by various users not responsible for the printer. It was used until it wouldnt print black anymore and then left dry without refilling for weeks. |

Patterns G, L and M are generated by combining the three primary colours of
Cyan, Magenta and Yellow. Thus the fact that those patterns print only means that your colours are working. The G, L and M patterns show the 'photo' black that the i850 uses for papers such as glossy photo etc. instead of the pigmented black ink found in the black cartridge. You either have a bad clog or a bad print head.

Also you may be seeing mixed black at the bottom which uses ink from all the colors but black. let me know how things turned out. |

Thanks Blitzko and beezer.
This is making sense now now. I did another, more thorough cleaning of the print head last night (where I tried to force cleaner through the black nozzles in particular). Still no go. The fact that nothing at all prints from the black nozzles makes me think it's a bad print head. So I'll try replacing that. Thanks again for the help. -Pat "Blitzko" wrote in message ...
