Re: wheelwriter 3 printwheel
If you know where the print solenoid is try a few drops of oil on the front and rear of the plunger. If the pad needs replaced it can be done without removing the printer from the machine but it is tough. If you know how to remove the printer take it out, remove the printwheel, there are two screws that hold the solenoid once the dolenoid is out the installation is simple.

You can try making sure all the wirng to the print wheel is secure, as a loose connection will reduce the power going to the wheel motors/solenoid (whatever actuates the wheel) and make the letters faint...
Check the cables, unplug and replug all the cables and make sure they're dead straight and fully home.. if this makes no difference it could be time for a fresh wheel or maybe there is a power supply fault?
Also there could be bits of paper/dust in the mechanism of the wheel stopping it hitting the paper at full strength, check around the wheel and if anything is stuck in the workings you can tease it out with a toothbrush.
hope this helps.
ALSO - are you sure the ribbon is not dried out? a "new" ribbon may have been on a shelf for years and actually be totally dry...
Solenoid pad is worn out. Look below left of the printwheel down inside the carriage and you should see a little white or opaque rubber pad. It needs to be replaced. You have to take it to a shop for proper repair. I have in the past, replaced it by digging the old one out with tweezers and hook. Then fish the new one in there.
Is the ribbon moving? Possible ribbon feed motor bad.Can you hear the printwheel letters hitting the paper? If not, then the solenoid pad is broken. Easy repair for a tech. A 7 to 15 dollar part depending on where you buy it. You can see it down on the left side of printwheel in front. A little round white or opaque pad. I have used a pair of tweezers and small bladed screwdriver and slipped a new in. Takes practice. Otherwise, you have to remove the carriage and take the solenoid out.
