The instructions in the manual are (1) remove the printer cover by pressing down on the (triangle) mark. (2) Lift up the old ink roller and remove it (3) Insert the new ink roller by pressing it gently into position (Use Canon Ink Roller CP-16) (4) replace the printer cover. My roller has the term "Pull Up" on the left side of the roller.
Unless the ink roller that you installed was dried out, usually, the replacement rollers just snap in place and are good to go. Check to make sure there is ink on the roller by either pulling the ink roller out again, and touching it with your finger. If no ink on your finger, you might have received a dried out replacement roller. Also the roller should be somewhat like a sponge. If you push against the sponge and it doesnt spring back and it stays indented, then the roller might also be bad. If you happen to have a bottle of ink for an ink pad, you can try soaking the roller with the ink so the roller is wet, (but not DRIPPING WET) and try it again in the calculator. IF you get some image for a little while, then I would say try a new fresh ink roller.
Hope this helps.
