The sophisticated built-in system of your HP DeskJet 9800 Printer constantly monitors the installed ink cartridges. The system will turn on the LEDs on the control panel in a certain light pattern, if an ink cartridge related abnormality is detected. All of these light patterns are listed and explained below.

• The left ink cartridge LED and the [Power] LED are on – The installed Tri-color ink cartridge is near the end of its useful life. You should install a new Tri-color ink cartridge soon after the initial appearance of the signal, in order to be avoided print quality issues.

• The right ink cartridge LED and the [Power] LED are on – The installed Black/Photo ink cartridge is nearly empty. Please note that a nearly empty ink cartridge can cause various print quality problems. Therefore, you should install a new Black/Photo ink cartridge as soon as possible.

• The two ink-cartridge LEDs and the [Power] LED are on – The Tri-color and the Black/photo ink cartridges are low on ink. You should install a new ink cartridge set soon after the initial appearance of the described light pattern, in order to be avoided a non-operational mode.

• The left ink cartridge LED blinks, and the [Power] LED is on – The built-in monitoring system cannot detect the Tri-color ink cartridge. You must make sure that the Tri-color ink cartridge is firmly inserted into the corresponding slot, and then test your inkjet printer. A new Tri-color ink cartridge must be installed, if the issue persists.

• The right ink cartridge LED flashes, and the [Power] LED is on – The Black/Photo ink cartridge is damaged or missing. You should try to resolve the issue by reinstalling the Black/Photo ink cartridge correctly. The installed Black/Photo ink cartridge will have to be replaced, if the problem persists.

• The two ink-cartridge LEDs are blinking, and the [Power] LED is on – Your HP DeskJet 9800 Printer cannot detect the ink cartridges. You must make sure that both ink cartridges are correctly installed, and then restart the printer. A new ink cartridge set must be installed, if the issue persists.
