This is a step-by-step process for replacing the tire (roller). Thanks to dizzyzuma
for helping me get the right part and get the procedure down.
1: You will need to manually shut off the printer in the middle of printing in order to release the tabs. Put in a few sheets of junk paper and print a few blank documents. You want to shut off the printer using the switch in the back when the roller is approximately in this position:
2: Hold the down the two side tabs that are locking the tire into place and press down on the tire with your finger. It should pop off relatively easily.
3: Turn the printer back on. The tire will rotate around to its starting position, but it will now be unlocked. Turn the printer back off.
4: Rotate the tire towards you and unhook the two bottom hinges. It should come off without much force.
5: Replace the old tire with the new tire.
6: Re-insert the tire onto one of the bottom hinges and rotate it around so that both of the bottom hinges (tabs) are in.
7: While holding the back of the metal bar with your fingers for leverage, press firmly with your thumb to snap the tire back into place.
8: Turn back on the print. You’re good to go.
