Hardware Forum / Peripherals / Printers / May 2007HP 1220C just blinks
The Cartridge LED blinks soon after you turn on the printer, just after the printer gets through its power-on tests. The ink cartridge indicated when I open the cover is the color cartridge. The cartridge is recent, but the date on the cartridge is 2004. (The cartridge is a generic no-name remanufactured one, with p/n NH-R6578.) Is there a "clock" in this cartridge's chip which will make the cartridge not useable after X number of years? I pulled both cartridges and cleaned all contacts in the carriage and on both cartridges. No joy. Suggestions?

I suspect the cartridge is faulty, they can fail. I suggestyou ask for a refund or replacement.

There is no clock in the cartrdige, and the printer has no idea about the date of the cartrdgie. The date on the cartrdige is two years from the original manufacture date, so this cartrdige really is five years old. > I pulled both cartridges and cleaned all contacts in the carriage and on > both > cartridges.

So these cannot be refilled, nor can CIS ink be used?. > Get a fresh cartridge. I replaced the color cartridge after the driver reported that "this cartridge is not compatible with the printer". It prints beautifully, now. > While you are at it check out: > http://www.hp.com/sbso/product/supplies/supplies_reliability_ink.pdf, > particularly chart 6 on page 14.

There is not a "chip" or other mechanism to prevent refilling on either the #45 or #78 cartridge. >> While you are at it check out: >> http://www.hp.com/sbso/product/supplies/supplies_reliability_ink.pdf >> particularly chart 6 on page 14.

You could try http://www.hp.com/united-states/consumer/inkjet/ink_refill.html or http://h71036.www7.hp.com/hho/cache/459406-0-0-225-121.html which have a similar message but a bit less data.

The original URL now works. I read the document and note that the tests it describes are comparing HP cartridges to remanufactured ones. Likely this is because back then (2003) no new 3rd party cartridges were being manufactured. I suspect the large number of failures were due to a used cartridge failing with so many hours on it (original life plus 2nd life). I'd be interested to see how new HP cartridges compare to the new (not remanufactured) cartridges now available.
