CHAPTER 1 FEATURES

The DL9300/9400 printer has a small footprint, is practically maintenance-free, and is designed to provide years
of reliable service. This printer uses a 24-wire dot matrix print head. The DL9300 is an 80-column printer and
the DL9400 is a 136-column printer.

The printer's major features are detailed in the sections which follow.

1.1 Print Quality and Copy Capability

The DL9300/9400 uses a compact print head containing 24 wires, each 0.2 mm (0.008 inch) in diameter.

Its letter-quality printing nearly equals that of daisy wheel printers, thanks to the 360 (h) × 180 (v) dpi print
resolution provided by a single pass of the 24-wire print head. Double-pass unidirectional printing applies up to
360 × 360 dpi for high-resolution graphics. Curves and very fine lines print clearly, enabling bar code printing.
Bidirectional printing increases the print speed, while unidirectional printing maintains precise print alignment.

Three types of print quality are available — letter, correspondence, and draft. Letter quality has the highest
resolution. Draft quality has the lowest resolution but is easy to read and has the highest speed. Each print
quality can be made thicker in multicopy mode which can be easily set from the control panel or by DLMENU.
Choose the quality to suit the application.

1.2 Print Modes

Multiple print modes enable word processing with great flexibility.

The DL9300/9400 has the following print modes and line spacing:

Print modes: Bold, shadow, double-width, double-height, condensed, superscript, subscript,

underline, justified, and proportional. Other modes, such as italic, multisize, outline,
shaded, and overlay are available depending on the emulation used.

Line spacing: 1, 2, 3, 4, 5, 6, 7, or 8 lines per inch

Programmable in 1/360 inch and other increments for image graphics

Both 8-bit and 24-bit graphics are available. The dot density is up to 1/360 × 1/360 inch.

Figure 1.1 shows printing samples.

Figure 1.1 Printing samples

1.3 Fonts and Character Sets

The DL9300/9400 has 18 resident fonts which are supported by a maximum of 58 national character sets. See
Appendix B for printing samples of resident fonts.

The following 15 resident fonts are letter-quality:

Bit map fonts: Courier 10, Pica 10, OCR-A 10, OCR-B 10, Prestige Elite 12, and Boldface PS
Scalable fonts: Courier (upright, italic, and bold)

Nimbus Sans
Timeless (upright, italic, and bold)

*1 Nimbus Sans is a registered trademark of URW Unternehmensberatung Karow Rubow

Weber GmbH, Hamburg.

The following three resident fonts are used for speed or condensed printing:

Correspondence, Draft, and Compressed

For downloadable fonts, up to 96K bytes of user-designed fonts can be downloaded to RAM.

(*1)

(upright, italic, and bold)

The DL9300/9400 has 56 or 58 national character sets (depending on the emulation) besides the basic character
sets. This makes the printer be adaptable to various languages. Note that some character sets cannot be used
with some fonts. See Appendix A for details.

1.4 Emulations and Compatibility with IBM PC Printers

The DL9300/9400 has two emulations in addition to the Fujitsu DPL24C PLUS command set. These are all
resident in ROM:

Fujitsu DPL24C PLUS, including bar code commands
IBM Proprinter XL24E emulation
Epson ESC/P2 emulation

The user can run many software applications without changing computer or application software, just by select­ing an emulation using the printer control panel or the DLMENU.

When the IBM Proprinter XL24E emulation is selected, the command set and aspect ratio of the graphics are
exactly the same as the IBM Proprinter when alternate graphics mode (AGM) is selected from the printer control
panel in setup mode.

Many 24-wire printers produce graphics having a different aspect ratio than other manufacturers' printers
because of different spacing of the print head wires. The DL9300/9400 produces the same aspect ratio as IBM
PC printers, including 9-wire printers. This offers the advantage of full compatibility with graphics software for
IBM printers.

cpi: Characters per inch
cps: Characters per second

The DL9300/9400’s buffer control enables data reception while other data is being printed. Other features, such
as logical seek, bidirectional printing, and horizontal and vertical tabulation also improve printer throughput.

The printer throughput, based on ECMA 132 (letter test pattern), is listed in the following table:

1.6 Automatic Paper Loading, Switching, and Tearing-Off

Paper handling is automated as follows:

Paper is loaded or unloaded automatically using the LOAD button on the control panel. The print position can
be adjusted for each paper type and path beforehand in setup mode.

Cut sheets can be used without removing continuous forms currently loaded. Pressing the LOAD button moves
the loaded continuous forms from the platen to the parking position (forms tractor). After pressing the PAPER
PATH button so as to turn on the CUT SHEET indicator, pressing the LOAD button loads a cut sheet up to the
platen. After the cut sheet is printed, pressing the PAPER PATH button so as to turn on the FRONT TRACTOR
or REAR TRACTOR indicator and pressing the LOAD button reloads the continuous forms from the parking
position.

There is no waste of paper in tearing off the continuous forms printed. Pressing the TEAR OFF button on the
control panel positions the bottom perforation of the last printed page at the tear-off edge provided at the front
cover or upper cover of the printer. After tearing off the last page, pressing any button backs the new first page
to the print position. This back-and-forth feeding is called tear-off feeding. Tear-off feeding saves pages.
Automatic tear-off feeding can be specified in setup mode; the printer waits for a while between jobs instead of
requiring the TEAR OFF button to be pressed. If a job ends and no data is sent from the computer, the printer
automatically feeds the last page to the tear-off edge.

1-4

1.7 Control Panel

The control panel has nine push-button switches, eight LED indicators, and a buzzer. Indication of functions and
statuses are easy to understand.

The control panel operates in two modes: normal and setup.

• Normal mode is used in daily operation such as paper path selection, paper loading and unloading, forms feed,
and line feed. It also enables copy control, tear-off feed, and top-of-form adjustment.

• Setup mode is used in customizing the printer to the user environment when first connecting the printer to the
computer or when printing special documents. It is also set using the DLMENU. Setup mode enables the
user to select printer features such as font settings, line and character spacing, page margins, serial interface
parameters, and other infrequently used functions.

1.8 Multiple Paper Paths and Switching (HCPP)

The DL9300/9400 has a wide variety of paper feed paths for both continuous forms and cut sheets. These paths
are almost straight so that the printer can use various types of paper and be adapted to various user environments.

The DL9300/9400 uses a friction feed platen, a standard tractor unit, and an optional tractor unit as the paper
feed mechanism for continuous forms. The optional tractor unit is exactly the same with the standard one. The
tractor unit is removable and installable at the front or rear of the printer. It pushes continuous forms toward the
platen. When the printer is shipped, the tractor unit is installed at the front of the printer.

The 9300/9400 uses a mechanism that switches these three paper paths by a command. This is called host­controlled paper path (HCPP) mechanism. The HCPP mechanism switches power transmission to the tractors.
Three states are possible: front tractor selected, rear tractor selected, and cut sheet selected. Switching is
possible through software or by the control panel. The paper on the platen is unloaded to the park position or
ejected, and then the paper feed path is switched. When switching from a cut sheet to continuous forms, the
continuous forms are automatically loaded to the print position.

As the cut-sheet feed mechanism, the DL9300/9400 uses the platen and an optional single-bin cut-sheet feeder
which is also installable at the front or rear of the printer. The SF930 is available for the DL9300, and the SF940
for the DL9400.

Figure 1.3 Cut-sheet feeders

Two tractor units can be used at the same time. Two cut-sheet feeders can be used at the same time. However,
at the front of the printer, the tractor unit cannot be used with the cut sheet feeder at the same time.

The 9300/9400 has eight paper feed paths depending on combinations of feed mechanisms. Figure 1.4 shows
these paper paths. At the right side of each illustration are listed available paper feed paths.

1.9 Automatic Print Head Gap Adjustment (APTC)

The 9300/9400 automatically adjusts the gap between the print head and the platen for paper thickness when
paper is loaded. This function is usually called APTC (abbreviated from automatic paper thickness control). It
is useful for users who often change paper types.

The print head carriage has a pressure sensor on the card guide which faces the platen. When paper is loaded,
the card guide is first set to the widest gap, pressed against the platen over the paper, and then backed for the
proper gap. The gap can be also adjusted by the paper thickness indicator in manual mode (the indicator is
accessible at the left of the printer when the front cover is open).

1.10 Automatic Interface Switching

The 9300/9400 has two interfaces: Centronics parallel and RS-232C serial. The dual interface allows the user to
connect the printer to both a network environment and a PC environment at the same time. The printer will
automatically switch to the proper interface (parallel or serial) when an AUTO option is selected for the
<INTRFCE> item by the HARDWRE function in setup mode.

1.11 Printer Driver and DLMENU

The 9300/9400 is delivered with two floppy disks.

One floppy disk contains printer drivers for Windows 3.x and Windows 95. The printer driver is a control
program to be installed on the computer for controlling document printing on the user printer. This printer driver
allows the application programs to make the best use of the DL9300/9400's functions. The printer driver for
Windows 95 has the plug and play detection capability.

The other floppy disk contains the DLMENU. The DLMENU is a printer remote setup utility program which
controls printer features in setup mode from the computer display in place of the printer control panel. This
greatly releases the user from tedious operation of setting up the printer from the control panel.

The printer control board consists of a main controller, memory, sensor receivers, drivers, a Centronics
parallel interface controller, and an RS-232C serial interface controller. This board governs the computer
interface, control panel, and printing mechanism using the main controller and memory that holds resident
character patterns and firmware including resident emulation programs.

(3) Control panel

The control panel is used by the user for operations such as changing or feeding paper, resetting the printer,
and selecting printer features in setup mode. The control panel indicates the printer status using a buzzer
and LED indicators.

(4) Power supply

The power supply provides power for operating the printer. Its specifications depend on the input AC
voltage.

(5) Cut-sheet feeder (user option)

The cut-sheet feeder is driven by a gear on the platen shaft. It has a cable to be connected to the printer for
controlling the feed rollers in the cut-sheet feeder. The feeder enables cut sheets to be fed and printed
continuously.

(6) Tractor unit (user option)

A second tractor unit can be installed if the user requires dual tractor feeding capability.

2.3.1 Exterior components

This section gives information on exterior components of the printer: covers, removable mechanism units, etc.
The upper cover is fastened with screws at the back (two for the DL9300 and three for the DL9400).

(1) Upper cover

The interface cable connector is on the right side of the printer, as seen from the front of the upper cover, so
the interface cable does not interfere with the paper feed path.

(2) Front cover

The front cover is opened to replace the ribbon cartridge.

(3) Paper table

The paper table guides a cut sheet manually fed by the user. It can also stack printed cut sheets when it is set
at the "down" position.

(4) Rear stacker

The rear stacker holds printed cut sheets. It must be set at the "down" position when an optional cut-sheet
feeder is installed at the back of the printer.

(5) Control panel

The control panel consists of an LSI, nine push-button switches, eight LEDs, and a buzzer. The switches are
used for operations such as loading and feeding paper and controlling printing pressure. Some switches are
also used in setup mode in place of the DLMENU. The LEDs indicate printer basic statuses and paper feed
path conditions. The buzzer sounds to indicate certain operating and printer statuses.

2.3.2 Printing mechanism

The two screws secure the printing mechanism to the bottom cover. The two hooks on the bottom cover hold the
mechanism in position.

(1) Carriage

The carriage supports the print head and ribbon cartridge, and slides left and right on the stay shaft. The
ribbon feed gear system moves the ribbon in one direction regardless of carriage movement. It has three
sensors: LRES, TOF, and APTC. The LRES detects both left and right ends of the carriage movement. The
TOF detects the top edge of paper. The APTC detects the gap between the print head and the platen.

(2) Carriage drive mechanism

The stay shaft and the stay guide support the carriage; the stepping motor and timing belt move the carriage
horizontally.

(3) Paper feed mechanism

The stepping motor drives the platen and/or tractors through gears to feed paper. See also the HCPP mecha­nism.

2-6

(4) Host-controlled paper path (HCPP) mechanism

The HCPP mechanism switches power transmission to the tractors. Three states are possible: front tractor
selected, rear tractor selected, and cut sheet selected. Switching is possible through software or by the
control panel. The paper on the platen is unloaded to the park position or ejected, and then the paper feed
path is switched. When switching from a cut sheet to continuous forms, the continuous forms are automati­cally loaded to the print position.

(5) Paper sensors

There are six paper sensors for controlling paper feeding:

Function Paper sensed Sensor type

Front paper set Cut sheet, continuous forms, and CSF Lever and transparent type photo-interrupter
Top-of-form Cut sheet, continuous forms, and CSF Reflective type photointerrupter
End of paper Continuous forms on the rear tractor Lever and transparent type photointerrupter
End of paper Continuous forms on the front tractor Lever and transparent type photointerrupter
Paper empty Cut sheets in the front CSF Microswitch
Paper empty Cut sheets in the rear CSF Microswitch

(6) Automatic paper thickness control (APTC) mechanism

The APTC mechanism adjusts the gap between the print head and the platen. When paper is loaded, the
print head is pressed against the platen and the sensor issues a signal when the print head is stopped by the
paper. The print head is then returned by a certain distance so that the gap (actually between the print head
and the paper) is properly adjusted regardless of the paper thickness.

2.3.3 Bottom cover

(1) Bottom cover

The bottom cover supports the printer mechanism.

(2) ROM board (control board with ROM)

The ROM board controls the host interface, control panel, and printing mechanism using an MPU and an
LSI circuit. Memory holds the resident character patterns and firmware, including resident emulation
programs. This board also has drivers and receivers for other components. The separate RS-232C serial
board is connected to this board through the cable.

(3) Power supply

The power supply outputs a constant voltage, regardless of the input AC line voltage, within ranges of 100 to
120 VAC or 220 to 240 VAC. The power supply is at the front of the printer and includes an AC line switch
and noise filter.

2-7

(4) AC inlet and CSF connector (rear CSF)

The AC inlet consists of the power input connector, the wiring cable, and the bracket on which the connector
for the rear CSF is mounted.

(5) CSF connector (front CSF)

The connector board for the front CSF is mounted at the front right of the bottom cover.

2.3.4 Options and consumables

(1) Cut-sheet feeders

A cut-sheet feeder allows both single-part cut sheets and multi-part cut sheets to be fed automatically.
The SF930 single-bin feeder is available for DL9300, and the SF940 single-bin feeder for DL9400.

(2) Tractor unit

An additional tractor unit can be installed in the printer. Because the standard tractor unit is installed at the
front of the printer at shipment, the additional tractor is installed at the rear of the printer. However, both
tractor units are the same, and installable at either position.

(3) Front cover (transparent type)

This type of front cover has the transparent window so that printed characters are visible without opening the
cover.

(4) Ribbon cartridge

The black ribbon cartridge contains a continuous inked ribbon and is installed on the print head carriage.

(5) Print head

The 24-wire print head is easily installed on and removed from the print head carriage.

3.6 Protection and Restrictions

3.6.1 Protection

To protect the print head, controller, and power supply, the printer checks for the following conditions:

• High temperature of the print head

• Damage to the carriage motor driver and the line feed motor driver or a short circuit in the motors

• Overvoltage of +34 V

To ensure printing quality, the 24 dot wires of the print head are divided into three groups and 3-pass
unidirectional printing is done when one of the following overload conditions is detected:

• +34 V power falls below the predetermined voltage.

• The print head’s thermal sensor detects a high temperature.

• Image data has a dot density higher than the prescribed printing duty.

Note:
No overload condition occurs when the printing load is smaller than printing 66 lines at 33% duty.

3-8

3.6.2 Restrictions

To avoid damaging the printer, do not:

• Feed lines continuously more than 3 minutes.

• Continue character spacing without printing more than 5 minutes.

• Continuously print lines of 5 characters or less (at 10 cpi) more than 5 minutes.

• Continuously print at 50% duty more than 1 minute.

Note:
If the above limits are exceeded, the printer’s service life may be greatly shortened.

3.7 Details on Forms Specification

The DL9300/9400 processes a variety of forms: letter paper, typewriter paper, copy paper, business stock forms,
labels, and ordinary envelopes. This section gives general specifications for continuous forms and cut sheets.
Before using paper, check that it satisfies the requirements below. For nonstandard forms such as envelopes and
labels, paper of nonstandard size or thickness, or cut sheets for autofeeding using cut-sheet feeders, consult your
Fujitsu representative.

Notes:

1. The total thickness of multipart paper must not exceed 0.65 mm (0.025in.), with each
part the same size and the part thickness uniform.

2. Multipart paper with a thickness or part count differing from specifications must be
tested before use.

3. The accuracy of line spacing cannot be guaranteed when using multipart paper.

4. Carbon interleaving is used for continuous forms only.

5. Because the carbon inserted between sheets of paper counts as one part, the number of
copies necessarily becomes 3 (in normal mode) or 4 (in multicopy mode) including the
original.

3.7.3 Multipart binding and perforations

To avoid paper jams when using multipart paper, note the following:

Binding continuous forms:

Multipart paper must be pasted or crimped (paper-stapled) at margins only. Metal staples and bar pasting must
not be used. Incorrect multipart paper may reduce print quality and make forms difficult to fold.

Procedure

(1) Point-pasting on two sides

(zigzag pasting)

25.4 mm (1 in.)

or less

Printing surface

(2) Crimping on both sides

(double-gathered)

76.2 mm (3 in.)

or less

Pros and cons

Preferred because:

• Forms remain flexible.

• Copy parts do not displace each other.

The greater the number of copies, the greater
the displacement.

(3) Point-pasting on one side and

crimping on the other side

Notes:

1. To prevent paper jams, avoid the following:

• Bar-pasting that makes forms stiff.

• Metal staples that cause forms to catch in the paper feed path. The print head may also be damaged in
printing on staples.

Metal staple

Bar pasting

2. The raised fold of the top part at the perforation (fold) must be 1 mm (0.04 in) or less, with the bottom layer
flat as shown below.

Example: 3-part

Bottom layer flat

3. When using continuous forms, the rear stacker must be down as shown below.

Rear stacker position for continuous forms

1 mm (0.04 in.) or less

3-16

Binding cut sheets:

When using carbonless or carbon-backed paper, be sure forms are pasted at the top. Paste must be applied
evenly and must not cause wrinkles, creases, or discoloration.

Glued top of sheets

Feed direction

Binding carbon-interleaved multipart paper (continuous forms only):

Process carbon-interleaved multipart paper as follows:

• Paste each carbon to the paper at the left and right margins at spots other than sprocket hole areas.

• Paste each carbon to the paper at the left and right margins including the sprocket hole areas while aligning
the carbon’s sprocket holes with those of the paper.

Perforations:

Poor or incomplete horizontal and vertical perforations cause paper jams. The tie-to-cut ratio for both types of
perforation must be 1 to 3.

3.7.4 Binding holes and preprinting

To ensure that paper is detected, do not let binding holes enter the paper sensing area.

Binding holes must be less than 8 mm (0.32 in.) in diameter.

Preprinting in the paper sensing area should be avoided.

3.7.5 Other precautions

• Use high-quality paper.

• Make sure that cut sheets are not curled.

• Handle and store forms carefully. Make sure that they are not wrinkled or damaged.

• Never store forms where humidity is high.

• When using multipart forms, envelopes, or labels, test-print before actual use.

CHAPTER 4 CONTROL PANEL AND DLMENU

The control panel is mainly concerned with printer basic status display and paper feeding in normal mode. The
DLMENU is used for remotely setting up the printer in setup mode.

4.1 Control Panel

The control panel has nine push buttons and eight LED indicators as shown in Figure 4.1. Except paper han­dling, capability of copying can be changed by a touch of a button.

In setup mode, the four arrow buttons can be used to set up the printer in place of DLMENU. The printer prints
the setup menu and the help menu that shows how to use the buttons to select parameters for printer operating
conditions. The red cursor engraved on the paper guide of the print head carriage indicates the active position.

4.2 DLMENU

Generally, the printer features are controlled by the printer driver through application programs. These are also
controlled by the remote setup utility program, DLMENU, stored in the DLMENU floppy disk which is fur­nished with the printer.

The DLMENU allows the user to change printer’s features directly from the computer display and keyboard.
Operations are easy enough that the user's manual need not be referenced once the user is familiar with the printer.

The DLMENU is useful to configure the printer to suit the requirements of user's computer, software, and
documents to be printed. It also has maintenance-aid functions which allows the user to print self-test reports
and print commands and data in hexadecimals.

The parameters changed using the DLMENU affect page layout, font, and printer control. If software programs
have printer drivers, the printer drivers control these parameters for the user. The user may never need to change
the settings manually using the DLMENU.

The DLMENU first displays the opening screen then the main menu. The main menu offers functions to select
print options for user documents. It also offers an operation guide of some keys and a help message line. If the
printer is not ready or has an error, a status message is displayed. The top menu bar offers pull-down menus for
file functions, emulation selection and interface setting, and maintenance. The user can select options or
perform a function by using the main menu and top menu bar accessed through the mouse or keyboard. One of
the six languages is selectable for messages when installing the DLMENU.

To use the DLMENU, the following are required:

• IBM PC/AT or compatible or PS/2

• PC DOS 5.02, MS-DOS 3.3, or higher

• VGA (640 x 400) or higher display

• Hard disk driver installed (1 MB essential for DLMENU)

• 3.5-inch 2HD floppy disk drive (1.44 MB)

The following main menu is displayed if the printer has no error after the opening screen is displayed.

data bits 1 to 8.

• Data 8 is the most significant bit, but is not used
in the 7-bit ASCII mode.

• All signals must go high at least 1 µs before the
falling edge of the Data Strobe signal, and must
stay high for at least 1 µs after the rising edge.

• Pulse signal indicating data reception completed
(or data reception enabled) status

• Issued when the printer switches from offline to
online

Reverse data transfer phase:
This signal goes high when data being sent to the
host is established.
Reverse idle phase:
This signal is set low then goes high to interrupt
the host, indicating that data is available.

Reverse idle phase:
This signal is set high until the host requests data
and, after that, follows the Data Available signal.

This signal goes high when the printer is selected
(online), and goes low when the printer is
deselected (offline).

Reverse data transfer phase:
Data bit 1, then data bit 5

Not used
Reverse data transfer phase:

This signal is set low when the host can receive
data, and goes high when the host has received
data. Following a reverse data transfer, the
interface enters the reverse idle phase when the
Host Busy signal goes low and the printer has no
data.
Reverse idle phase:
This signal goes high when the Printer Clock
signal goes low so that the interface re-enters the
reverse data transfer phase. If it goes high with
the 1284 Active signal low, the 1284 idle phase is
aborted and the interface returns to the compat­ibility mode.

5.2.3 Data transmission timing

The 9300/9400 uses a bi-directional parallel interface complying with IEEE 1284. This interface is also compat­ible with the conventional Centronics interface. Data transfer from host to printer is performed according to
Centronics standard, called compatible mode. Data transfer from printer to host, it is performed according to the
IEEE 1284 standard, called nibble mode.

In compatible mode, the printer receives data from the computer in handshaking mode based on the Busy and
Acknowledge signals from the printer and the Data Strobe signal from the computer. For the Data Strobe and
Acknowledge signals, the timing of the Busy signal must be as shown in the compatible mode of Figure 5.5.

To send data from the printer to the host, the interface enters the nibble mode where data is sent in units of four
bits (nibble) using four output signal lines as data paths. The data transfer sequence in nibble mode involves
negotiation phase, reverse iddle phase, reverse data transfer phase, and termination phase. Figure 5.5 shows the
reverse data transfer phase where data is sent.

5.3.4 Timing diagram and cable configuration

The printer enables or disables input control signals for the printer linked with the RS-232C interface, enabling
communication via the RS-232C interface as well as more simple communication.

There are mainly two ways to connect the RS-232C interface:

• Full-wire

• 3-wire

Notes:

2. Some computers may not require wire 2 .

5.3.5 Data protocols

The following four protocols are used for the RS-232C serial interface, depending on the computer hardware.

• XON/XOFF or DC1/DC3

• DTR

• RC

These protocols prevent overflow of the print data receive buffer when interface data transmission is faster than
buffer data printing. The printer uses specific character codes or an interface signal for each protocol to inform
the computer of buffer status.

Selecting IBM character set 1 validates the ETX/ACK protocol, regardless of the emulation used.

(1) XON/XOFF or DC1/DC3 protocol

The XOFF (DC3) code (hexadecimal 13) is transmitted from the printer when less than 255

(*1)

bytes remains
in the buffer. The XON (DC1) code (hexadecimal 11) is transmitted when less than 255 bytes of data
remains in the buffer.

*1 This value is 63 bytes when the print buffer is configured for 256 BYTE in setup mode.

Data processing cannot be guaranteed if data is transmitted to the printer but sufficient buffer space is not
available after the XOFF code has been transmitted.

When the printer is first turned on, the DTR signal is set to the space state (ready) and an XON (DC1) code
is transmitted from the printer. When the printer is placed offline, the XOFF code is transmitted even if the
buffer is not full. The XON code is transmitted when the printer is placed online again.

If paper runs out, a NAK code (hexadecimal 15) is sent from the printer.

(2) DTR protocol

The DTR signal (pin 20) is set off (low). That is, the Busy signal is issued when 255

(*1)

bytes of data remain

in the buffer. When the printer is placed offline, the DTR signal becomes inactive.

*1 This value is 63 bytes when the print buffer is configured for 256 BYTE in setup mode.

The computer must stop transmission within 255 bytes after the DTR signal is set off (low).

Valid data cannot be guaranteed if data exceeding the buffer capacity is transmitted without regard to the
DTR signal.

Buffer-full recovery timing:

Data transmission is suspended when the DTR signal is set off (low). Even in this state, printing continues.
When the data length of the available area in the buffer exceeds 255 bytes, the DTR signal is on (high). That
is, a “ready” signal is issued.

(3) RC protocol

The RC protocol is the same as the DTR protocol, except that it uses the Reverse Channel signal (pin 11)
instead of the Data Terminal Ready signal (pin 20).

5.4 Command Sets

5.4.1 Overview

This section gives an overview of the DL9300/9400 printer’s command sets. It may not provide the command
details and programming examples need to modify software packages or writing user programs.

This printer uses three types of command set for resident emulation for the following models:

DPL24C PLUS command set: Fujitsu DL series printers
IBM Proprinter XL24E emulation: IBM Proprinters X24, XL24, and XL24E
Epson ESC/P2 (LQ-1170) emulation: Epson printers using the ESC/P2 command set

The next three sections list commands for each emulation.

Note:
Values or small letters in parentheses are represented by one byte of data. (1) and (0) are represented by
01 and 00 in hexadecimal and by ASCII 1 (31 hex) and 0 (30 hex). (n) is a value whose effective range is
also shown.

CHAPTER 6 MAINTENANCE

6.1 Overview

The DL9300/9400, with its simple mechanism, is highly reliable and easy to maintain. Components need very
little adjustment and are easy to replace.

6.2 Preventive Maintenance

No scheduled maintenance is required beyond keeping the printer clean, which helps ensure the service life and
MTBF.

6.3 Maintenance Philosophy

The printer is designed and built to minimize maintenance.
No periodic lubrication is required.
To ensure printing quality, the following are done at the plant:

• Every unit is checked and tested before assembly.

• All products go through a full final inspection.

6.4 Diagnostics

6.4.1 ROM/RAM checking

When power is turned on, ROM sum and RAM write/read are checked automatically.

6.4.2 Error display

Operating conditions are checked during printer operation and, when an error is detected, the error status is
displayed by flashing the PAPER OUT indicator.

6-1

6.5 Test and Adjustment Functions for Maintenance

The DL9300/9400 provides the following test functions for adjustment and checking at maintenance:

6.5.1 Self-diagnostics

Self-diagnostics prints test pattern pages without using the computer. The operator or maintenance personnel
can easily check electrical and mechanical states of the printer. If there are printing errors, self-diagnostics
distinguishes between printer errors and computer errors. It is also used to confirm correct operation after error
recovery.

6.5.2 Hexadecimal dump

The DL9300/9400 prints received data, including commands, in hexadecimal, which is especially helpful if a
software problem occurs.

6.5.3 Vertical alignment

Full lines of vertical bars are printed bidirectionally. This enables fine adjustment between forward and
backward printing so that vertical bars of each print line form straight lines. This adjustment is necessary for
printing vertical ruled lines or graphics.

6.5.4 Print position adjustment

The top of the paper, left print start position, and line spacing pitch (when using cut sheets) are adjusted for the
first print line when paper is loaded on the platen. This adjustment depends on the top margin specified by
application software. The fine adjustment is necessary for formatted or ruled paper.
