4.4 Interface Selection

e printer has 2 interfaces; the parallel interface and Type-B optional interface. These

erfaces are selected manually by Default Setting or selected automatically.

Manual SelectionOne of 2 interfaces can be selected by Default Setting.

Automatic SelectionThe 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.

Interface State and Interface SelectionWhen the parallel interface is not selected, the interface gets into a busy state. When the Type-B serial interface card is installed and it is not selected, the

interface sends XOFF and sets the DTR signal MARK. When the optional interface is not selected, the printer sets “OFFLINE” bit of MNSTS register to the

optional interface.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 and the

printer resets “OFFLINE” bit of MNSTS register to the optional interface. Caution

that the interrupt signal such as a -INIT signal on the parallel interface is not effective while that interface is not selected.

4.5 Prevention Hosts from Data Transfer Time-out

nerally, hosts abandons data transfer to peripherals when a peripheral is in busy state for zens of seconds continuously. To prevent hosts from this kind of time-out, the printer eives data very slowly, several bytes per minute, even if the printer is in busy state. This

wdown is started when the rest of the input buffer becomes several hundreds of bytes. At t, when the input buffer is full, the printer is in busy state continuously.

4.6 IEEE1284.4 protocol

e packet protocol described by IEEE1284.4 is supported on the parallel I/F.o function modes of IEEE1284.4 protocol, “Off” and “Auto” are available, and one of m is selected according to the value of Default setting. (See 1.5.2.3 "Default Setting")

is printer mechanism consists of Printhead, Paper feed mechanism, Carriage movement chanism, Tractor feed mechanism, Platen gap adjustment mechanism, Ribbon feed

chanism, PF motor, CR motor, detectors, and so on.

2.1 Printhead

e printhead prints data from the control board on paper using the ink ribbon. The

nthead is mounted on the carriage unit.

2.2 Paper Feed Mechanism

e paper feed mechanism picks up paper and transports it to the printhead, then ejects it p by step or continuously driven by the PF motor. PF motor drives the paper feed

chanism gears and the platen roller. The top of form and paper out condition are detected

3.1 C293PSB/PSE Power Supply Circuit

is printer can be powered by either of two power supply boards: the C293PSB (120V) ard or the C293PSE (230V) board. The function of these two boards is the same, except a difference in the primary circuitry. The power supply outputs the DC current cessary to drive the printer control circuit and drive the mechanism. The input voltages

d fuse ratings for these boards are as shown in the following table:

e power supply circuit outputs voltages used to drive the various control circuits and the

chanism, as shown in the following table:

e power supply circuit consists of the line filter circuit, ZC-RCC (Zero-Cross Ringing

oke Converter) switching circuit and 5V chopper regulator IC. The AC voltage is first ut to the line filter circuit for higher harmonics absorption, then input to the switching

cuit and transformed to +35VDC. +5VDC is generated from +DC35V by the regulator . The over current / voltage protection circuit is also designed on the board.

e power switch is set in the secondary circuit that is controlled by the signal PSC from

control panel.

ubleshooting more difficult. This section, however, provides simple and effective ways

facilitate troubleshooting. The following flowchart illustrates the main steps of the

ubleshooting process.

ote: This information is necessary only for the servicers who repair to component vel. Servicers who repair to unit level can ignore this section.

3.1.1 Main Component

The following components can be chmultimeter.

*: Set meter to ohms. Then disconnecpower off.

Measuring the DC voltage or checking some signal waveforms

requires switching on the printer without housing covers and shield

plate. Therefore, do take care of safety operation and not damage

other unrelated componets.

NOTE: All tools and instruments l

Before disassembling, assembling or adjusting the printer,

disconnect the power supply cable from the AC power socket. Failure to do cause personal injury.

Be careful with the printhead when you handle it, as it may be

very hot just after printing. Do not touch the heat sink attached to the switching FET (Q1) on

the power supply board, just after power off as it may be very

hot. Never touch the heat sink attaches to the switching FET (Q1)

while at AC power cable is connected to the AC outlet, as it is not electrically isolated.

To maintain efficient printer operation: Use only the recommended tools for maintenance work. Use only the recommended lubrications and adhesives. Adjust the printer only in the manner described in this
