The hammer may be coming to rest into or otherwise be interfering with the movement of the printwheel, It could be a bad motor or the hammer cam may be not cycling properly to its' home position or may require replacement of the hammer cams assembly. Typically, if you observe the hammer moving slightly towards the paper after a print cycle, then the usual repair is replacing the cams assembly. If you are technically inclined, it is possible to remove the cams assmebly and retime the hammer cam by repositioning the helical spring into a different slot in the flange on that cam assembly. This will establish the proper position of the hammer cam at rest position.

Trying to get the asterisk @ for email on a computer

Probably your keyboard is set to a different character set or language. To fix this go to control panel and click keyboard properties, there should be a tab for input locals. This sets the language and character set for your keyboard. To use various characters, you can use start , then type charmap.exe in the box and it will bring up a character map where you can select various characters such as the copyright sign etc. to use. Most windows from 2000 newer also have osk.exe, this draws up an onscreen keyboard you can click with your mouse to type.
