The manual for the Canon P170-DH calculator is found on the canon usa web site. It is 22 mg in size, but prints out to 4 pages in English, Spanish and French.
According to the manual: Use only Ink Roller CP-13.
There are four figures showing the steps, so you'll have to imagine it.
1. Turn power switch off.
2. Remove the printer cover (Figure1).
3. Hold the tab of the ink roller. Lift the ink roller out of the base (Figure2).
4. Insert the new ink roller into position. Push down on the center of the ink roller until it locks into place (Figure3).
5. Replace the printer cover (Figure4).
Print out the manual for yourself and put it in a safe place.
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.
