Sharp AJ1800 printer - won't print colour

I suggest you that purchase new Printer cartridges and replace it with old . May be some problem in your cartridges .

You have to refill both.

When printing in BLACK, a small amount of the COLOUR ink also is used.
This "trick" prevents the COLOUR ink-jets from clogging, due to not being used.

So, you need to have a "good" COLOUR ink-cartridge.

switch to black and white on the printer settings.make sure ignore colour warnings are turned off

if that doesnt work youll need to replace the cyan,get it refilled for less or order online to reduce cost

no if ur filling the catridge more times the printer going to damage

take the cartridges out and clean them also clean where they go with a lint free cloth then replace them.

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.

if the test pages come out OK then the problem can not be the printer !!!!!!!
it must be from the application

Dear Black Rose
It is strongly recommended to change your colour cartridge.
Or it can be possible that you did not use your colour cartridge for a long time.
The nozzle of colour cartridge are blocked, if you did not use your colour cartridge for a long time.
Purchase a new cartridge if you can or go for a local refiller to refill (if possible) your colour cartridge.
Thanks

Yes, do you refil your own inks. Colour contamination occurs primarily when users overfill ink holes with any colour, then this colour runs into others and voila, a yukky mess. If cartridges are fairly new, heres the quick easy fix. Remove cartridges that are causing the problem, in your case all! Using a proper cleaning solution (you can get this free in refill kits or buy it sepeartely, i got mine from supermarket, works well) and cotton buds, thoroughly clean down where the cartridges sit. There will be both fresh ink and dried ink, so you will have to repeat over and over until all or most colour is gone from cotton buds. Now, let it dry and air, leaving printer cover open. You now have to bleed the black ink as it sounds like it is overfull. This can happen in refilled cartridges, but even store bought ones can have faults. Sit the black cartridge on wet paper towel, on a clean icecream lid or marg lid, even a plate will do, just one that you don't mind ink on by accident. Let it sit a minute or so, now lift it up, and wipe it gently with a wipe (i use unscented baby wipes-huggies, do not laugh, they work well!) press it firmly on a folded tissue, and it should leave a nice clean neat black vertical little line. If it doeas, place it back in its place in printer. Leave open for now. The colour cartridge should need cleaning too, by doing the same, each time you lift it off wet paper towel, wipe it clean, and press it on a tissue to see clean neat 3 colour line. If not, bleed again until it does. When it does place it back in printer and reset ink levels once cover is shut. Try printing now.
