1.3.4 Interface Selection
The printer has 2 interfaces; the parallel interface and serial interface. These interfaces are
selected manually by Default Setting or selected automatically.
oManual Selection
One of 2 interfaces can be selected by Default setting.
oAutomatic Selection
The automatic interface selection is enabled by Default Setting. In this automatic
interface selection mode, the printer is initialized to the idle state scanning which
interface receives data when it is powered on. Then the interface that receives data
first is selected. When the host stops data transfer and the printer is in stand-by
state for the seconds specified by Default Setting, the printer is returned to the idle
state. As long as the host sends data or the printer interface is in busy state, the
selected interface is let as it is.
oInterface State and Interface Selection
When the parallel interface is not selected, the interface gets into a busy state.
When the serial interface is not selected, the interface sends XOFF and sets the
DTR signal MARK. When the printer is initialized or returned to the idle state, the
parallel interface got into a ready state, the serial interface sends XON and sets the
DTR SPACE. Caution that the interrupt signal such as a -INIT signal on the
parallel interface is not effective while that interface is not selected.
1.3.5 Prevention Hosts from Data Transfer Time-out
Generally, hosts abandons data transfer to peripherals when a peripheral is in busy state for
dozens of seconds continuously. To prevent hosts from this kind of time-out, the printer
receives data very slowly, several bytes per minute, even if the printer is in busy state. This
slowdown is started when the rest of the input buffer becomes several hundreds of bytes. At
last, when the input buffer is full, the printer is in busy state continuously.
1.3.6 IEEE1284.4 protocol
The packet protocol described by IEEE1284.4 is supported on the parallel I/F.
Two function modes of IEEE1284.4 protocol, “Off” and “Auto” are available, and one of
them is selected according to the value of Default setting. (See 1.4.2.3 "Default Setting")
oAuto:
Communication is carried out in the conventional mode until a magic string
(1284.4 synchronous commands) is received. By receiving a magic string,
communication in IEEE1284.4 packet mode is started.
oOff:
Communication is carried out in the conventional mode. A magic string (284.4
synchronous commands) is discarded.
NOTE: The packet protocol of IEEE1284.4 allows a device to carry on multiple
exchanges or conversations which contain data and/or control
information with another device at the same time across a single point-
to-point link.
The protocol is not, however, a device control language. It does provide
basic transport-level flow control and multiplexing services.
The multiplexed logical channels are independent of each and blocking
of one has no effect on the others. The protocol operates over IEEE1284.

CARRIAGE HOME POSITION (HP) DETECTOR
The table below is the HP detector specifications.
HP detector detects the signal right after when the CR motor switches the phase.
2.2.2.1 High speed skip method
At no-printing area, the carriage moves at high speed compared to the normal carriage
speed at printing. This is called carriage control.
2.2.3 Ribbon Mechanism
2.2.3.1 Ink Ribbon Shifting Mechanism

COLOR MECHANISM INITIALIZATION
The printer mechanism initializes when the power is applied or when recovering from the
energy saving mode.
oColor mechanism initialization
Color mechanism initialization shifts color mechanism for the black ink area to be
at the home position. Color mechanism initialization shifts the carriage at the same
time to prevent the ribbon from hanging on the printhead.
When the buffer is cleared or when the printer is under the pause condition, the
color mechanism initializes and waits for the next printing command.
2.2.4 Platen Gap Adjustment Mechanism
This mechanism is to adjust the distance between the platen and the printhead (platen gap)
according to the paper thickness.
The following is the components of the LX-300+/1170 platen gap adjustment mechanism
and its explanation. (Refer to Refer to Figure 2-5.)
oCarriage: Mounts the printhead.
oCarriage guide shaft: Shifts the carriage horizontally.
oAdjust lever and Parallelism adjust bushing:
Installed at the both ends of the carriage guide shaft
oPlaten gap detector (PG_SW)
Carriage guide shaft is eccentric toward the adjust lever rotating center. Due to this, when
rotating the adjustment lever back and forth, the printhead shifts toward and against the
platen to adjust the platen gap. When printing on thick paper such as postcards and
envelops, set the adjust lever over the 1st level. PG detector shifts the printer to the copy
mode from the printing mode. Printing speed will be lowered but it prevents wire from
breaking off.

RPE DETECTOR
RPE detector is installed on the paper path at the back of the printer. The table below shows
the RPE detector specifications.
BPE DETECTOR
BPE detector is installed right under the platen. The table below shows the BPE detector
specifications.
2.2.5.1 Page Length Measurement
Page length measurement is a process to convert the following value to the number of
printing lines.
Value = [The number of paper feed pulse from the paper top (top margin: 4.2mm) until RPE
detector detects paper end] + [forms over-ride specified paper feed pulse] - [adjustment
value]
oWhen CSF is used:
The uncertainty of the paper end detector may vary the number of printing lines
within the same paper size. To avoid this, when CSF is used, page length
measurement calculates the printable lines and if the paper is longer than the
printable lines, the number of printing line is considered the printable lines (fixed
value).
When paper is shorter than the printable lines, the printer prints the fixed number
of lines by forms over-ride function (which allows the fixed number of lines to be
printed even when RPE detector detects paper end).
oWhen CSF is not used:
When loading paper manually or when tractor feed is used, the number of printing
lines of paper end is determined by forms over-ride function after BPE or RPE
detector detects paper end.

6.1 Maintenance
Appropriate maintenance is necessary to keep the printer in the best condition and prevent
from troubles.
6.1.1 Cleaning
Use neutral detergent or diluted alcohol to clean the dirt on the outside. Vacuum dust or a
small piece of papers inside the printer.
6.1.2 Lubrication
The lubrication point of LX-300+/1170 is as shown in the following table. Refer to the table
for the type and the amount of oil to be used for each point. Oil and grease have a great
affect on the performance of the product, especially on the durability and the performance
at the lower temperature. EPSON determines what kind of and how much of oil to be
applied based on the various information and analysis.
NOTE: Lubrication must be applied during the re-assembly process.
For lubrication points, refer to the following figures.
W ARNING nWhen performing the maintenance, remove the AC cable from
the AC socket.
nNever touch the printhead right after printing, as it is highly
heated.
C A U T I O N
nNever use thinner, tricren, or ketone solvent, as it may deform or
deteriorate the plastic parts or rubber parts.
nUse the specified amount of the specified oil.
