After printing, the printer performs forms feed as specified by the control
code or

command.

When the forms are fed to the line preceding the last

line printed, the Acknowledge signal goes to 1 and the Busy signal goes to 0,

enabling print data to be received for the next line.

Thus,

the data is

received at the same time as forms feed.

The printer goes offline (the deselect state) when one of the following

conditions occurs:

the START/STOP switch is pressed:

. When the Input Prime signal goes to 1:

the printer receives The DC3 code

. When the printer is inoperable (Fault state):

The top of form

and the bottom of form

referred to in this section

are defined as follows:

. TOF

When the forms control buffer

data has been loaded, the TOF is the line

to which channel 1 is first specified in the

data.

When the

data has not

been

loaded or when channel 1 is not contained in

the

data, the TOF is the first line on the page.

When the FCB data has been loaded, the BOF is the line to which the BOF
channel is first specified in the FCB data.

The BOF channel can be

specificed with any channel number from 2 to 12 from the operator panel.

F o r

the channel specification method, refer to Operator's

When the FCB data has not been loaded or when the BOF channel is not

contained in the FCB data, the BOF is the last line on the form (Page). If

-the skip-over perforation feature,

which specifies the number of lines

skipped to avoid printing at or near the perforation, is specified, the BOF
line is the last line without the skip-over perforation

For

the method of setting the skip-over perforation feature, refer to Operator's

Guide.

5.2 Interface Signals

This section explains the interface signal functions and physical

specification.

5.2.1 Interface signal lines

Centronics-compatible interface signals use both the positive and negative

logic.

For the positive logic, a positive

is used as 1 and a negative

voltage as 0.

For negative logic the opposite is true.

Table 5.1 shows

Centronics-compatible interface signal lines.
