Ink cartridge Original HP 1x Yellow C4823A / Nr 80 for HP DesignJet 1055 CM

I look at the procedure for replacing the ink on the designjet 1050 designed at 10:55 what you shouldn't do is just go along to the end can just pull one of those out they're pressurized it's gonna be difficult to remove it and just not a good idea so what we need to do over to the front panel select the ink menu the two ink drops and press enter and then just highlight placing cartridge and press enter and what you'll hear is you hear air being dumped do now back over to the ink he'll then easily be removed it's not pressurized anymore get your new ink just install it that's it job Doug control panel would just tell you that the ink cartridge is successfully installed and just to press ENTER to continue there we go the machine is now ready
