A = Interconnect Board
B = Paper Low Switch Cable
C = Journal Take-up Motor Cable
D = Test Switch Cable
E = Brass Standoffs
Note: Before removing the Interconnect Board, you must separate the printer
from the Base Assembly, remove the Serial Interface Board (if used),
and the Control Board. Refer to "Base Assembly," "Serial Interface
Board," and "Control Board" earlier in this chapter. For ease in
removing any of the boards, remove the Transport-Auto Cutter
Assembly from the printer.
1. Turn the printer right-side up.
2. Disconnect the following cables from the Interconnect Board:
♦ Paper Low Switch (routing of the cable differs depending on the model)
♦ Test Switch
♦ Journal Take-up Motor
3. Turn the printer upside-down.
4. Remove the Carriage Cable Assembly (F, G, H, J) from the Interconnect
Board by sliding it off the board.
When reinstalling, be sure that the cable contacts the board directly.
You do not need to separate the Pressure Bar (J) from the Cable Clamp (F).
If any of the pieces are broken, you can separate them in order to replace
the broken parts.
To separate the parts, carefully bend the metal tabs of the Cable Clamp (F)
outward slightly with a pair of long needle-nose pliers. Don't bend the
plastic tabs on the Pressure Bar (J) as they are easily broken. Be careful not
to damage the Carriage Ribbon Cable (H).
5. Remove the three Brass Standoffs (E) holding the Interconnect Board (A)
to the printer with a 1/4 inch nut driver.
Note: Reverse these procedures to reinstall the Interconnect Board.
