Intermec EasyCoder PC4—Service Manual
The top cover locks are shorter in the DT model than in the TTR model,
because there is normally no need to separate top cover and the print
frame, when there is no need for ribbon reload.
Note: Parts are marked with "L" or "R" indicating left or right side (frontal
view).
DT Model
The locks are attached to the print frame moulding with Phillips screws. To
access the left side lock, you will need to remove the cable cover as shown
in the instructions for replacing the Feed Switch PCB earlier in this chap-
ter.
Two spring hooks that are engaged by the base lock (see Chapter 5.7) are
fitted to the print frame moulding using Phillips screws. The spring hooks
are identical for the DT and TTR models.
The left-side spring hook is fitted inside the same housing as the Feed
switch PCB. To access it, you will need to remove the cable cover as shown
in the instructions for replacing the Feed Switch PCB earlier in this chap-
ter.
The right-side spring hook is easily accessible in the DT model whereas in
the TTR model, you will need to dismantle the ribbon takeup mechanism
(see Chapter 4.8).
