CISS Continuous ink supply systems (CISS) for HP Designjet DJ500, DJ510, DJ800 are aftermarket kits for inkjet printers that feed ink to a special permanent cartridge via tubes connected to external bottles or reservoirs. The cartridge never runs dry or needs to be replaced. Instead ink can simply be added to the bottles as they run low.

Ink cartridge: HP10 and HP82
Color: BK, C, M, Y

The plastic bottles that are part of continuous ink supply systems sit alongside the printer. There may be four or six (and sometimes 8) bottles depending on the printer model. Each one is filled with the proper color ink. A tube runs from the bottle cap to the ink

Cartridge inside the printer. The tubes are bound together into a "ribbon" cable. Kits also include a syringe for initial setup to clear the tubes of air and draw the ink.

Continuous ink supply systems save the user substantial money in replacement cartridges, which on top of cost, are discarded while still holding ink. Bottled ink is not only more economical but all ink is eventually used.

Another advantage of continuous ink supply systems is that the cartridge is always full, delivering even color every time that remains consistent regardless of the size of the print run. Large runs of photographs or other jobs can be spooled without worry of running out of ink. The external bottles are clear, making it a snap to refill any colors that may be running low, while bottles hold significantly more pigment than cartridges, minimizing maintenance.

Then enjoy the savings and the ease of a continuous inking system and print to your heart's content.
