The ink well in the printer looks like it

had to get a new printer

Depends which red blinking light. I assume the red light is the resume light. The green light is the power light. If the Power and the Resume light are blinking alternately, then you have a paper jam somewhere in the printer. remove the paper jam and you should be fine.

Go into control panel, click on System.
Goto the Device Manager.
Goto your printer port, open its properties, and select "don't use this device".
Turn off the printer, turn it back on. It should be happy.
Go back into the properties and reenable the device.

Return the cartridge and get a refund, it's defective. Make sure you buy brand-name cartridges, too.

check your cartridges, perhaps one or both need to be changed.

look on page 40 for the blinking lights and see how to solve it ,it might be a jam.

There should be some error .So you know how to remove the catridges just remove it n re insert it properly.If there are any paper jams try removing it also.and by the way if you haven't installed the drivers for HP deskjet this problem may arise.So make sure you ahve don this.Also this can be happened if the printer have some hardware problems.So none of this solutions are working its better to consult it with an expert.

cos green color is out. what u do is refill the color catridge or rather buy a new color catridge n ur up again.
hope u find help here
thank u

use a tooth brush n dip in a spirit or fuel then clean the catridege head sensor very well for both black and colored then leave it to dry aftyer which reinsert yr ink and check if it still occures and ur sure yu have replaced the ink then the catridge head is bad
thank u

In your print utility, you need to calibrate your printer, which will print a test page and realign your cartridges. It should be OK after this. If not restart the printer and the computer.
