Operation Panel
The printer interface kit consists of two PCB s, th e printe r cont rolle r board
(Controller) and the printer interface board (PIFE).
1.2.1. Printer Data Path
Through the serial and/or parallel interfa ce(s), the Cont rolle r han dsh ake s wit h
the host(s) and receives print data, using one of the available emulation
modes. Then the CPU creates an imaginary page in the memory using the
fonts stored in the ROM. After one page of print data has be en created, the
Controller sends the video data through the print er data interface to the LIF
on the FCU for printing. The PIFE emu lat es th e prin t data an d co nt rol sig na ls
for the LIF to work correctly, and supplies the 24.1 MHz clock signal to the
LIF for 300 dpi printing.

POWER DISTRIBUTION
1.2.2. LCD/LED Data Path
The three LEDs on the operation panel are always dedicated to the Controller. They indicate the status during printing, and are directly co nt rolled by the
Controller.
In Printer Mode (Function 35), the LCD display and four one-touch dial keys
are dedicated to the Controller to access Printer functions. Within th e Prin ter
functions, some settings are not available because of limitations to the machine’s hardwa re. So, the CP U on th e PI FE monitors the function status and
the settings to indicate on the LCD, and mod ifies the data if necessary (e.g.,
Half Letter size paper will not be displayed as a possible paper size).

The PIFE generates +5VD for th e Con tro ller from the +24VS supplied by the
FCU.
+5V for the PIF CPU is directly supplied by the FCU. The +5V line is returned
to the FCU as +5VDEN, so that the FCU can detect whether the print er int erface is installed or not.

HIGH.
Parallel data bits 1 to 8. For 7-wire connections,
the most significant bit can be fixed at 0 using a
user adjustment.
Indicates that data has been received and the
printer is ready to receive more data.
A HIGH (Centronics) or LOW (Dataproducts)
indicates that the printer cannot receive data.
The printer is busy when the interface already
contains a byte from the computer but not yet
taken by the controller, when the printer is off
line, and when there is a printer error. The
Centronics signal is called BUSY, and the
Dataproducts signal is called DEMAND.
This correcsponds to the Centronics SELECT
and the Dataprioducts READY and ONLINE
signals.
Reserved for data direction control. If HIGH, data
goes from host to printer. If LOW, it goes the
other way. The pin is pulled up on the controller
board.
Indicates when the printer is out of paper, off
line, or in an error condition.
Other pins: Not used.

ready to receive data. If the printer ready protocol is not
selected, DTR is always HIGH (always ready to
receive). If printer ready protocol is selected, the printer
can only accept data when DTR is HIGH. When DTR
goes LOW, the computer must stop sending data within
128 characters. The active signal level can be changed
with a user adjustment.

Monitor Timing
The FCU monitors the PRINT signal from the controller every 2 ms to detect
if a print request is co ming from the controller or not. After T1 has passed
since the FCU detected the PRINT signal to be active , the FCU drop s
VSREQX to low so that the controller can acknowledge that the printer is
ready to receive one page of image data. After one page of data h as b ee n re ceived from the contro ller, the FCU inactivates th e VS REQX signal until
PRINT is activated again for printing the next page.

STS informs the controller of stat us inf ormation, such as the current paper
size and any mechanical problems tha t are enco untered.
The FCU informs the controller of the printer status (STS ) in an 8 bit serial format, in response to a command (CMD) fro m the cont rolle r. If a status signal
(STS) is not received within T5 (100 ms) after the controller sends a command, the controller will resend the command to the FCU.
