How do you change the ink cartridge on the credit card printer verifone 510?

The Verifone 510 is typically a point-of-sale terminal that uses thermal printing, which means it doesn’t use ink cartridges. Instead, it prints on thermal paper, which reacts to heat to create text and images. So if you're experiencing printing issues or fading receipts, the most likely fix is to replace the thermal paper roll, not an ink cartridge.

Here’s how to replace the paper roll:

Open the printer cover

Locate the paper compartment, usually found at the top or back of the terminal. Gently press the release latch or button to open the cover.

Remove the old roll

If there’s an empty or used roll, take it out and discard the leftover paper.

Insert the new roll

Place a new roll of thermal paper in the compartment. Make sure the paper feeds from the bottom of the roll (like a toilet paper roll coming from underneath).

Feed the paper

Pull a few inches of paper out past the edge of the compartment.

Close the cover

Snap the cover shut, ensuring it clicks into place.

Test it

Press a feed button (if available) or run a test transaction to make sure the paper is feeding and printing properly.
