Print up to 90,000 pages per colour and save yourself the purchase of original HP 970, 971 cartridges. The installation of this system takes longer than the installation of cartridges (approx. 1 hour), but then you can print at extremely low cost - permanently. Please read our installation instructions carefully or watch our video.

The CISS for HP 970 and 971 cartridges enables you to permanently print at very low cost with the following printers:
HP Officejet PRO X 551 DW,

The CISS is delivered with 4 x 1L of black, cyan, magenta and yellow ink. The entire ink can be filled into the tanks of the CISS. The amount corresponds to more than 10 HP 970 and 971 cartridges for each colour, which means you save yourself the purchase of 40 original cartridges.

This ink was developed and produced by Octopus Fluids GmbH & Co. KG in Germany. It is highly pigmented and presents the same printing properties as the original ink. When the ink included in the delivery is used up, the tanks of the CISS can be refilled. Attention: Do not use all-round ink! All-round inks do not work with these printers.

The CISS is assembled as described in the included instructions, then the ink is filled into the corresponding tanks. Next, the CISS is installed in the printer, and you can start printing. The tanks of the CISS should be refilled before they are completely empty. Until then, you can print up to 90,000 pages per colour with a single refill.

The CISS and the inks are not an original product and were not produced by the printer manufacturer. The names of manufacturers and trademarks are indicated for identification purposes only and are the property of their respective owners.

Customer evaluation for "CISS for HP 970, 971, HP Officejet PRO X cartridges with 4x1L of ink"

Great customer service, but product missing parts

First of all, I want to start this review saying that the company has fantastic communication with the customer. It was a major reason why I decided to purchase their product and not from another company. I am going to explain why I am *currently* giving it a 6/10 stars.

Unfortunately, the product I received did not arrive with all the parts listed on their website. The kit was missing the air plugs that are used in one of the first steps in converting the ink cartridges. I am pretty disappointed, especially since their product is on the more expensive side compared to their competitors.

Additionally, the ink reservoir tank is different from the one picture on the website/youtube videos. Instead of having plastic bags, it is a hard plastic case (comparable to the competitors).

Luckily, the company was quick to respond and is sending me the air plugs. I feel I cannot give this product a higher rating because I am still waiting on the parts to arrive and I have not yet been able to complete the conversion of my printer. Once I am able to use their product, I will update my review accordingly.

Thank you, I hope this review helped you decide on whether to purchase this product!

Fantastic ever

I bought one of these over 1 year ago. I printed several doubled sided books out of over 450 pages, and many numerous documents. I think that Moses refills my bags every night. I am not sure it has even dipped that I can measure it. At this rate maybe 10 years of usage? And, they are great to help you with it. And I have left that printer unattended for over three months, came back, cleaned the head through the software and it picked right up and printed great. Now please make it for the newer ones!!

Answered questions

Question from Sasa A*** , Date:

"Should I install the CISS when the original cartridges are empty or before my printer shows "low ink level"? Would refilling / installing the CISS reset "low ink level" of the original cartidges? The printer is HP Officejet Pro X476."

Answer from the shopowner

"Hello, it is crucial to connect the CISS to cartridges without any low-ink-level indications. Once the ink level is low, the cartridges are only usable for a limited amount of pages. Please install the CISS to full or at least half full cartridges."

Question from Anonymous A*** , Date:

"Can this set be used with Pro 477dw (the successor of Pro 476dw)?"

Answer from the shopowner

"Hello, unfortunately we can not garantee that the CISS and the inks will work with the HP 973 cartridges. The HP 973 cartridges have new chips and we can not tell you if the will work with the CISS. Your Octopus Team"

Question from Matthias D*** , Date:

"Guten Tag, ich bin mit diesem System für meinen X476 seit 5 jahren sehr zufrieden, vielen Dank dafür (über 100.000 Seiten). Nun möchte ich gern zusätzlich einen 477 anschaffen. Kann ich dieses gute CISS dann mit der Tinte für den neuen Drucker ebenfalls kaufen? Vielen Dank für Ihre Nachricht und besten Gruß"

Answer from the shopowner

"Guten Tag, wir danken für Ihre Anfrage. Dieses CISS System ist leider weder zu dem HP Color LaserJet Pro MFP M 477 noch zu dem HP PageWide Pro 477 kompatibel. Ihr Octopus Team"
