Hey Guys,
   We don't really work on these but our customer wanted us to take a look at it to see if we could repair it.  Our tech brought the typewriter in to our shop to see if someone could figure it out.
Problem:  The Ribbon advances really slow, so when typing, the print ball will strike the ribbon in the same place multiple times. It is advancing the tape to the upper, middle and lower part of the ribbon.  We degreased the swing bar (was stuck) that has the teeth wheel that digs into the used ribbon.  Again, the ribbon is advancing, but way to slow.
Any suggestions or help would be greatly appreciated.
Thanks.
Have a good day.
Mark

Replacing the covers is a skill that has to be learned, and patience is a must.  Start by moving the carrier all the way to the left, and then insert the rh cover front side down, holding it by the edges, and scoop it underneath the cord, watching that you don't snag the metal tapes... then, sliding the cover toward you, get it under the aforementioned top tapes... You then have to get the d.i. cable (that's the metal cable that's against the frame under the rear rail) hooked into the tab at the rear of the cover, and positioned so that it goes under the cover throught the cutout at the rear of the cover.  Then you snap the front of the cover into the latches mounted on the frame.  Then you puch the bracket holding the cable down, and mover the carrier all the way to the right.  For the lh cover, perform the same basic motion, but this time you have to clear the lh carrier cord pulley, and again be sure not to catch the tapes as you scoop the cover into place.  Remember to push the d.i. cable bracket down again. This is a job that gets easier with practice, and calls for a steady hand.
Good luck -

Thanks for the Replies everyone.
Courtney's suggestion was the winner.  When our tech took the spring loaded tension arm assembly apart, he must have pushed down too much on the spring loaded part that was above the double gear.  Once we adjusted that part, the ribbon feed worked fine.
Thanks for saving this from the landfills for now.
One more question which should be an easy one for the techs that know what they are doing.  (Unlike us...lol)  The 2 black covers that cover all of the drive gears, rotate tape, etc... How the heck do those go back on?  We had 3 tech's that said they thought they knew how it went back on, but non of them could get the 2 covers back on.
What's the trick? What's the secret...LOL
Thanks again for the help.
Hope everyone has a safe, and happy Holidays and a Prosperous 2009.

You should probably also check to be sure the ribbon is on the outside of the arm that releases the supply side (on the left), very common for customers to get it on the wrong side when they change a ribbon.

What about the (R)ibbon / (S)tencil selector on the front of the carrier ?? Set to S ??

there's a dual gear under the ribbon has a spring loaded part on top if it doesn't pop up in the regular position you get small ribbon movement  but i would check the ribbon feed tension  with the ribbon off hold the spiked roller and hold down the underscore key see if the roller can power thru   good luck   Courtney
