Fujitsu M304X Printer User Manual


 
After printing,
the printer performs forms feed as specified by the control
code or VPU 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:
.
When
the START/STOP switch is pressed:
. When the Input Prime signal goes to 1:
.
When
the printer receives The DC3 code
(X'13'):
. When the printer is inoperable (Fault state):
The top of form
(TOF)
and the bottom of form
(BOF)
referred to in this section
are defined as follows:
. TOF
When the forms control buffer
(FCB)
data has been loaded, the TOF is the line
to which channel 1 is first specified in the
VPU
data.
When the VFU data has not
been
loaded or when channel 1 is not contained in
the VPU data,
the TOF is the first line on the page.
.
BOF
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.
For
the channel specification method, refer to Operator's
Guidly.
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
sp'ecification.
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 voltae 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.
