There are 2 types of FCT: 8-channel and 12-channel.

Figure 4.11 shows a

FCT, where each FCT sprocket hole corresponds to each line of

the form.

Punched holes, called channels,

indicate special positions of

the forms, and are used for forms feed control by software.

This is the

same as for 8-channel

a new forms feed format is used, the old

FCT must be replaced with one for the new forms feed

The FCT is read automatically when the printer is turned on or when the

RUN switch on the FCT unit is pressed in offline mode.

The RUN switch

enables a new FCT to be read.

Because the FCT unit determines that

channel 1 of the FCT is the start position, the FCT unit reads punched

hole data starting from channel 1 to the next channel 1 detected.

The data from the FCT unit is sent

the interface control

microprocessor.

Then, the IFC microprogram loads the data into the FCB in

the internal buffer.

Make an FCT as follows:

Punch a hole at the first column on the center line of the first
sprocket hole (channel 1 as the top of form), as

in Figure

4.11.

For subsequent lines, punch holes according to the forms feed format.
Note that columns 1 to 12 (1 to 8 for an a-channel

correspond to

channels 1 to 12 (1 to 8 for an 8-channel FCT).

For example, punch a

hole at the third column on the center line of the fourth sprocket
hole when channel 3 is specified for the fourth line in the forms

feed format.

For more examples, punch holes at the fifth and seventh

columns on the center line of the eighth sprocket hole when channels

5 and 7 are specified for the eighth line in the forms feed format.

Figure 4.11 shows these examples.

Punch a hole at the first column (channel

on the sprocket-hole

center line corresponding to the last line of the print form and cut

the FCT there.

Align the center lines of the first sprocket hole (A in Figure 4.11)
and the last sprocket hole (A' in Figure 4.11) of the FCT, glue
ends together, and confirm that no punched holes are covered.

Notes:

1) Because channel 1 is defined as the BOF, there must be

one hole, which indicates channel 1, per print form.

2) The FCT should not exceed 255 lines.

3) An FCT must be longer than 10 inches so that the FCT can

be installed in the FCT unit. When the form length is

less than 66 lines for a

FCT

lines for

a-channel

the same hole pattern

be repeated

once on the FCT to extend the FCT length.

4) The

FCT

used for this printer must

to the

specifications shown in Section 4.5.
