Question about IBM 6400 Matrix Printer
I have an IBM 6400 matrix printer. Recently it started "skipping" parts of letters. Now in that same spot all the way down the sheet it cuts out part or all of the letter that should be printed there. Someone told me the actuator needs cleaned. How would I go about doing this?
IF trouble in first row - you ribbon is tracking wrong - replace
You may have junk in the ribbon mask also. No parts needed for that. You need to rotate the hammerbank. Remove ribbon and black cover, the whole shuttle will tipback toward you when you unscrew the allen wrench - watch out for the paper tractors they will hang on the ribbon mask. The ribbon mask is held on by magnetic field - just pop off carefully. clean holes with toothbrush and water - dry. (if the trouble is a bad actuator - 4 allen screws to remove a group of hammers - if using short paper - you can use a group from the end of the printer). reverse to fix
