Note: Before removing the Control Board, you must separate the printer from
the Base Assembly and remove the Serial Interface Board, if present.
Refer to "Base Assembly" and "Serial Interface Board" earlier in this
chapter. For ease in removing any of the boards, remove the Transport-
Auto Cutter Assembly from the printer. Refer to "Transport-Auto
Cutter Assembly" earlier in this chapter.
1. Remove the five screws (B) holding the Control Board (A) to the printer
with a 7/32 inch nut driver.
Note the position of the two longer screws in the illustration.
Caution: Do not bend the posts protruding from the bottom of the board
during the next step.
2. Gently pull the Control Board (A) straight out at the corner near the fuse.
Note: Reverse these procedures to reinstall the Control Board.
When reinstalling the Control Board, carefully insert the square posts
protruding from the bottom of the Control Board into the proper holes
on the Interconnect Board. If this is not done properly, the
Transformer, Control Board, and Interconnect Board may be damaged.
