HP DeskJet Ink Advantage 5645 Ink Replacement Guide

  1. Turn on the printer and load plain white paper into the input tray.
  2. Open the cartridge access door. Wait until the ink carriage moves to the center and stops moving completely.
  3. Lightly press down on the empty cartridge to release it, then pull it out of its slot.
  4. Take the new CompAndSave HP 5645 cartridge out of its package. Pull the orange pull-tab to remove the plastic tape.
  5. Do not touch the copper-colored contacts or the ink nozzles. Touching these parts can cause ink system failure or clogs.
  6. Slide the new cartridge into the empty slot at a slight upward angle (tri-color on the left, black on the right), then push up gently until it snaps into place.
  7. Close the cartridge access door. Wait for the printer to calibrate and print an alignment page.

HP DeskJet Ink Advantage 5645 Ink Cartridge FAQs

Why are ink cartridges so expensive?

OEM ink and toner manufacturers claim that the high cost of toner cartridges is due to the research and development of technologies to deliver high-quality ink and toner. 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 is 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 ink knowledge base, and you will be redirected to the right page.

What happens if you use the wrong ink cartridge for a printer?

If you unknowingly purchase the wrong ink cartridge for your printer, it will most likely not fit inside the machine due to different fittings depending on the model. But in case you manage to install it inside your printer, the printer will not recognize it and will not print.
