index finger, nail down, under the tab on top of the ink roller. Gently lift the
ink roller out of the compartment.
4. Lower the new ink roller (IR-21) into the compartment and align the hole
in the ink roller with the pin in the compartment. Press down until it snaps into place.

You have to remove the ink roll door, on the front left near the bottom. Pull the roller out with a tweezers, add a few drops of ink to the roll and re-install. No matter how careful you are, you will get some ink on your hands...

Reset the printer. Thanks.

I had the same problem... tried reinking... tried running alcohol thru print head, etc, etc,.. turned out the print head had gone bad... replacing it fixed the problem. Probably not what you wanted to hear !... About $65 bux to fix it.. half the price of a printer... but if you have already got a stock of ink for it... and don't want to risk being unable to reink a new one on account of an imbedded chip... and the printer is otherwise in good shape... not a bad investment.

No, what you need to understand. Most printer companies have a chip installed in the ink cartridge. This chip is linked to the printer’s software. It knows you have refilled the ink because your putting the same cartridge back in. To get around this you will need at least two in cartridges. When one has emptied you install the second (refilled) cartridge. (Fooling the software). Some you need a total of three cartridges.
Remember printers are cheep compared to a few ink
replacements.

This should help in the long run.
Good Luck!

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.

A few possibilities here: One, is your ribbon cartridge dried out (essentially out of ink)? Dot Matrix printers aren't near as common now, and if your cartridge has been in the retailer's stock for years, then it could indeed be dried out. Another, the ribbon isn't being advanced, or spooled. The ribbon is spooled as the head carriage moves back and forth. If it isn't being spooled, the ink in the spot over the printhead will be quickly depleted. A no-spooling condition is usually caused by a problem in the cartridge itself. Also, make sure the cartridge is properly seated in the holder. If it isn't, the drive spindle isn't fitting up into the cartridge properly, and might not actually drive the mechanism inside the cartridge. Lastly, if your cartridge is dry, they can be reinked if you can find someone with the reinker to do it. I once did ribbon reinking with a Macinker as a side business, and someone in your area might have one of those rigs. Otherwise, just buy a new cartridge, and hopefully it will be reasonably fresh, with good ink.
