Black Ink has been re-filled, canon MP240 says its empty )=

It needs to replace the ink cartridge, you can no longer use it, does the printer continue printing even there has a message saying the black ink is out?? if Yes, it is normal for the cartridge if it is already CISS...

The printer requires both cartridges to have ink before the printer will initialize and operational. Even if you are only printing black and white both cartridge have to contain ink or the printer will error out. This is standard on all ink jet printers from every manufacturer. You will have to get ink before you can print.

No, Canon does not have this facility. Also mostly greyscale is not light black but rather a mixcture of the 3 primary colours. You should have a reset/resume button on the printer - hold this in for a slow 5 seconds to de-activate ink warnings per cartridge that is giving alarms. Proceed carefully and only print text that is black so that the colour printheads do not burn out.

How I can reset my canon mp270,lamp B is lighting all the time. I have filled black ink and know my printer dont recognizes cartridge. My computer shows that it is empty.

you need to have both cartridges somewhat full to run, there is a initialization routine that the printer goes thru and if you don't have good cartridges with ink it won't let you print.

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

just fill up all the catridge bcoz in colour printer anyone of them is not fill up the printout not coming properly , after filling the catridge just check

Not sure about your machine but my Cannon would not work when my colour ink was low. The store I bought it says the manufacturer does this to sell coloured ink as well as black. The setting might say for black ink but there is a certain amount of colour goes in as well. I hardly ever used colour as I do business letters so I purchased a black ink jet which uses a black powder and I get 3000 pages for about 75 dollars worth of black jet powder.

Hello,

Do you still need help with this problem?

This printer will take either the PG-30 or PG-40 (larger size) cartridges for black ink, and either the CL-31 or CL-41 (larger size) cartridges for color ink.
