Removing and Replacing Components

Supplement to Chapter 4: Removing and Replacing
Components
This chapter is presented as a SUPPLEMENT to Chapter 4 in the T6215 Maintenance Manual.
The only procedures presented in this supplement will be those that differ from the T6215.
Procedure 5: Hammer Bank Removal
Careful: The Hammer Driver CBA has components that are static sensitive! Use
appropriate ESD grounding procedures when handling the Hammer Bank
Assembly.
Note:
Steps 1 through 6 are the same as in the T6215 Manual. Subsequent steps are
modified due to the addition of a fourth linear bearing for the T6218 Hammer
Bank.
Step 7:
Remove four KEPS nuts underneath the Hammer Bank – one set of two
from the left side and the other from the right.

Step 8: Slide the upper left tractor as far to the left as it will go. Lift the
hammer bank and shuttle assembly out of the printer, being careful not
to damage the ribbon shield.
Note: As the hammer bank is removed, notice the “wedge” under the lower
left linear bearing. Do not lose this piece.
