Unfortunately, CISSmarket is not stocking or selling a CISS for HP Deskjet F2420. This is because this printer is using a low cost print head, which is designed to last for very few pages only, until it is replaced, together with the new ink cartridge. The print head is actually integrated with the ink cartridge.
Because of this, and based on our experience, we know the HP Deskjet F2420 will not work properly when fitted with a CISS and have consequently decided not to stock or sell this product.
What can you do reduce printing costs ? We recommend you discard this printer and buy a new model, which is using a permanent printhead and is fully compatible with the continuous ink supply system - CISS. You will recover the investment quickly and then continue to print up to 20 times cheaper vs. using ordinary cartridges. Do not hesitate to contact us at firstname.lastname@example.org for a customized recommendation.
