How do I install HP Designjet 450c cartridge?

  1. Open the cover and push it all the way back.
  2. The ink cartridge's carriage will automatically move, so make sure to wait for it to completely stop moving before you proceed.
  3. To remove the cartridge, simply press down and then pull it towards you.
  4. Get your new CompAndSave HP Designjet 450c ink cartridge. Open it over a sink or garbage can to avoid any mess in case it leaks, as sometimes, factories tend to overfill the ink cartridges. Make sure to touch the black plastic part only, then remove the covering tape that is usually bright in color along with the plastic protective case, if there is, before installing it.
  5. In the printer carriage, place the new HP 450c ink cartridge. Gently press down and push the cartridge until it clicks into place.
  6. Lower the cover when finished.

HP DesignJet 450c Ink FAQs

Why are ink cartridges so expensive?
OEM ink and toner manufacturers claim that the high cost of these cartridges is due to the research and development of technologies to deliver high-quality ink and toners. However, it is worth noting that there are generic cartridges that exceed OEM requirements while being less expensive than their counterparts. CompAndSave's compatible and replacement ink and toner cartridges are engineered to meet or exceed OEM standards. That means to say, you can have the same print quality and page output without spending a fortune. Please keep in mind that using generic, remanufactured, or replacement cartridges will never void the warranty on your printer. For additional information, please visit our Ink Knowledge Base.
