HP Deskjet 9800 Printer does not recognizes the cartridge and red light blinks even when the HP 97 (right cartridge) is installed. I have cleaned the contact area with Swab/alcohol but still it does not recognize the cartridge. I have removed the cartridge and re-installed it(genuine cartridge) many times but still does not work.

the problem is that your printer
can not recognize the cartridges

clean the contacts or replace the cartridges

If by referring to the left drip light you mean the bottom left light; this is the indicator light for the color ink cartridge:
Left print cartridge light blinks, Power light on. Tri-color print cartridge is damaged or missing.
? Reinstall the print cartridge. If the error persists, replace the print cartridge.
? You can still print with one cartridge

it is possible that once the computer and printer are communicating that the error messages could also be resolved by running the printer diagnostic program.

If your computers do not recognize the printer, uninstall the driver, if you had installed a specific driver, and then go to the site below to download a driver for your operating system and specific printer:

The blinking ink light means that the printer does not recognize one of the ink cartridges. Power the printer off, pull out the power cord, wait for awhile, replug and turn the printer on. If the light no longer blinks, ok. If not, try installing another cartridge pair if you have them available - even if they are old used ones. If the ink light continues to blink with different cartridges or if you don't have any different cartridges, old or new, you have a dilemma. Do you want a new printer or do you want to continue to chase this problem. To chase this problem, get new cartridges and install them (half the price of a new printer). If that works your set, but if not you need to have your printer serviced which is doubtful that it is worthwhile doing so.

If you mean the ink cartridge lights, when they are blinking and the power light is on, it indicates both cartridges are damaged, missing or improperly installed. Take the cartridges out and reinstall them. Replace them if the problem persists. A full list of the codes is in the manual:

I hope this helps.

Normal 0 Could have a corrupt driver.
Disconnect the printer or at least be sure it is turned off. I'd do both and when the CD software program asks you to connect the printer to the USB port, do so and it should again work properly.
Hope this helps. Bud

The light you describe is the ink light.
When that light is blinking, try this.

Turn on the printer. Open the front cover and look at the carrier for the ink cartridges. There is a white arrow right above the latch for the color cartridge.
Once the carrier stops moving, the white arrow should be pointing to a symbol which represents the problem (the reason the light is blinking.) Examples are low ink black, low ink color, sick black ( replace ) , sick color ( replace ).

IF you have just replaced your black cartridge, you might need to replace your color cartridge too.
This printer will not work without both ink cartridges installed and full.
You cant print with a full black and an empty color cartridge unfortunately, even if you only want to print black.

Hope this helps!

i replace a new cartridge hp deskjet 9800,the power button keep flashing.......?

i had the same problem -- this is what finally worked for me. turn the printer off, wait several seconds, then turn it back on. when i first turn it on, the ink lights and the resume lights blink a few times. as soon as that stops, before the ink cradle or any other parts move, lift the lid. the black piece in front of the ink cartridges will drop down so that the cartridges can be changed.
