Compatible HP GT51/GT52 ink bottle: installation, reset and compatibility

HP refillable-reservoir printers (Ink Tank, Smart Tank and DeskJet GT) use bulk ink bottles instead of printhead cartridges. The compatible HP GT51/GT52 ink bottle is the direct replacement for these systems, with an approximate yield of 5,000 pages per bottle and manufacturing to the ISO 9001 quality standard. Here we explain what it is, how to install it and what real savings you can expect.

What it is and which printers it works with

The GT51 reference usually corresponds to black ink (higher volume) and GT52 to the cyan, magenta and yellow colours. It is not a cartridge: you refill the printer's reservoir directly from the bottle. It is compatible with these models:

• HP DeskJet GT 5810, 5811, 5820 and 5821
• HP Ink Tank 115, 315, 318, 319, 410, 415 and 419
• HP Ink Tank Wireless 410 and 415
• HP Smart Tank 500, 505, 508, 511, 514, 515, 516, 517 and 519

Always check the reference printed on your original bottle or on the reservoir label before buying. You can see the full listing on the product page.

How to install it and what to do if it "doesn't recognise the ink"

One advantage of these systems is that the bulk ink does not carry a chip per bottle as conventional cartridges do, so you will rarely see the typical "cartridge not recognised" warning. Installation is straightforward:

• Open the reservoir lid for the corresponding colour.
• Remove the bottle's seal and slot it into the reservoir nozzle. The anti-drip design releases the ink as you connect it.
• Let the reservoir fill up to the maximum line, without going over it.
• Close the lid and confirm the ink level on the panel or in the HP Smart app if your model asks for it.

If, after refilling, the printer reports low quality or lines in the printout, run a printhead cleaning from the maintenance menu and wait a few hours for the ink to stabilise in the system. When the warning comes from a printer update rather than the bottle, check our article on how HP firmware blocks consumables.

Yield and savings versus the original

This bottle is manufactured to ISO 9001 and offers an estimated yield of 5,000 pages, in line with what you would expect from a reservoir system designed for high volume. In practice, the cost per page falls noticeably compared with original ink, which is precisely the buying argument for these printers.
