INK Having moved house & printer in store for 4 wks the first colour print showed blue only. Tried new colour cartridge but then printing showed only red & yellow & no blue. Then tried another colour cartridge from new batch & nozzle check showed blue & yellow only and then blue only. I had cleaned the print head numerous times in between. Please help! [email protected]

have youtried to clean the cartridge contacts of the printer?

Great job on cleaning the cartridges and even trying 3 new ink cartridges. Pretty much you did the basic troubleshooting already. This looks like a hardware problem but I strongly suggest you contact Lexmark technical support to further investigate the problem. Thanks.

Many thanks for the suggestions received. Have been told by HP to
change the black printhead - which has solved the problem!

It could well be the printer head (the area where the cartridge locks into the printer) has gummed up contacts. Take a soft, lint-free cloth and wipe down gently wipe down the face of the contacts. Keep wiping until all residue is removed. Reinstall a color cartridge and then run the printer's software alignment utility (this is part of the software that comes with the printer).

No you cannot. Each one of your cartridges is smart chipped. When this cartridge registers as empty it acts as an on/off switch thus turning the printer off.'

You need to replace the empty cartridge in order to print.

Go printer settings and check option to print only black.

probably dirty or broken print head. suggest you replace it or get new blue cartridge if your machine has seperate colour cartridges.

this is not a printer problem, you have a problem with colour cartridge! u can fix this in 2 diferent way: 1. replace the colour cartridge with new one, or gently clean the nozzle cartridge with a wet tissue until the cyan colour mark a line on the tissue just like the others colours: yellow and magenta. maybe must repeat this several times.

I have a similar problem - i can print all colours apart from red.
I've tried cleaning, deep-cleaning, and even bottom plate cleaning but of none if this improves anything.

Tried cleaning the print heads and nozzles with cotton buds, but this dont do anything. Even tried re-seating the cartridges but this does nothing either

Have you tried a new colour cartridge? This is a classic sign that the cartridge may be low on ink. When printing text, assuming you are printing black, it is likely that the black cart is doing most of the work so the gaps are insignificant. You could try printing text in several different colours. If the colour cartridge is low, you'll find that some colours may be ok but others may have gaps.

Best to try a new cart if you have one.
