If printer is not in use for 1 week.Is we need to remove the cartridge?

You know, mine is not using it for one year. so, i sold my printer already... it is wise to remove the cartridge but you need to cover the cartridge otherwise it will dry out the ink. If that happens, printing will be a problem especially your printer head because the ink will be dry and hard. Trust me.

i never removed the ink catridge from my own printer even if i did not use it for 1 month.but you can try removing it and see what happens after that.if the color quality is still fading there is something wrong with the printer.you could bring it to the shop and ask them what is the real problem. it might due to whether the ink is original or compatible.some printers will get spoil when you use compatible.i am using compatible also but it is working fine with me as the quality is the same as the original ink

ya..for the safety you need to remove the cartridge..if not the cartridge will not be able to work like the normal way it does..
