The bottom cover and the upper cover are fixed with a back screw.
b. Front cover
The front cover is opened to replace the ribbon cartridge.
There is an Interlock SW for safety.
c. Soundproof cover
Soundproof cover is opened when the continuous form is set.
How to handle refer to the Quick Start Guide or User’s Manual.
d. Rear stacker

e. Control panel
[LED type]
The control panel consists of an LSI, 10 push-button switches, 1 dial, 13 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. The LEDs indicate printer basic statuses and paper feed path conditions.
The buzzer sounds to indicate certain operating and printer statuses.
[LCD type]
The control panel consists of an LSI, 11 push-button switches, 1 LCD, 8 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. The LEDs indicate printer basic statuses and paper feed path conditions.
LCD displays the state of the printer. The buzzer sounds to indicate certain operating and printer statuses.

The printing mechanism fit into the bottom cover. And Upper Cover holds it in position.
a. Carriage
The carriage supports the removable 24-wire print head, 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 four sensors: LRES, TOFL, TOFR and APTC sensor. The LRES detects both left and
right ends of the carriage movement. The TOFL/R detects the edge (top, left, right, bottom) of paper.
The APTC sensor detects the surface of paper for control the gap between the print head and the paper.
b. Carriage drive mechanism
The stay shaft and the stay guide (upper angle) support the carriage; the stepping motor and timing belt move
the carriage horizontally.
c. Paper feed mechanism
There are two stepping motors. One of them drives the rollers and another one drives tractors.
d. Host-controlled paper path (HCPP) mechanism
The HCPP mechanism switches power transmission to the tractors. Three states are possible: front tractor is
selected, rear tractor is selected, and cut sheet is 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.
e. Automatic paper thickness control (APTC) mechanism
The APTC mechanism adjusts the gap between the print head and the paper surface. Before start printing,
the print head is approach to the platen until APTC sensor is pressed against the paper surface. And then the
print head is 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.
f. Paper sensors
There are six paper sensors for controlling paper feeding:
Name
Function
Sensor type
TOFL
TOFR
Detect the top edge for paper loading
-TOFL is for front loading
-TOFR is for rear loading
Detect left and right edge for area over control
-TOFL is for left and right edge (small width paper)
-TOFR is for right edge (large width paper)
(Right and left are reversed for rear feed)
Detect the bottom edge for detecting paper end.
-TOFL is for front loading
-TOFR is for rear loading
Photo reflectors
FTRPE
RTRPE
Detect the continuous forms at the tractor for as
follows.
-Control the paper loading sequence.
-Detect the paper parking position.
-Detect the near paper end of continuous forms.
Photo interrupter
PSS
Detect the cut sheet on the paper table for auto
loading.
Detect the bottom of the cut sheet for control carriage
position to detect the paper end .
Detect the leaved paper on the paper table for display
remove paper indicator.
Photo reflectors
APTC
Detect the surface of the paper for control the print
head gap.

(3) Lower cover
Figure 1.7 Electric components of DL7600
a. Lower cover
The Lower cover supports the printer mechanism and electric units as follows.
b. ROM board (control board with flash 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 sensor receivers convert signals from the
sensors. The drivers supply power to motors, print head wires, and other components. LAN relay board is
connected to this board through the cable.
c. Power supply unit
The power supply unit supplies DC40V and DC5V by two transformers.
Two transformers realize that printer displays fatal alarms though printer shuts down DC40V.
(Even if DC40V is shut down, DC5V still remains. )
d. AC inlet and AC switch.
The AC inlet has protective earth cable. In order to prevent an electric shock, it must be fixed to frame ground.
The AC switch has cables to connect the Power supply unit and AC inlet.
e. CSF connector (front CSF)
The connector board for the front CSF is mounted at the front right of the lower over.

(4) Option and consumables
a. Cut-sheet feeders
A cut-sheet feeder allows both single-part cut sheets and multi-part cut sheets to be fed automatically.
The SF94 single-bin feeder is available for DL7600.
b. 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.
c. LAN card.
A LAN card is available as a printer add-on option. A user installable function, the LAN card can be installed
only on printer models with the Centronics parallel + USB interfaces.
d. Large paper table
The large paper table helps to increase operability when large cut sheets are used.
Also, sheets that are output from the front are easier to keep properly organized.
e. Small paper table
The Small paper table helps to increase operability when small cut sheets are used.
f. Large stacker.
The large stacker accommodates sheets output from the rear.
It is used in continuous printing with a cut sheet feeder.
g. Print head
The 24-wire print head is easily installed on and removed from the print head carriage.

19
CHAPTER 2 UNPACKING, PERFORMANCE CHECK, AND
CONNECTION
2.1 Overview
The DL7600 printer comes packed for transportation.
After unpacking and before installation, the printer must undergo self-test printing. Installation requires minimum
time and expense.
2.2 Notes on Installation
For best results, note the following points when installing the paper:
・Place the printer on a level, vibration-free surface.
・Keep the printer away from sunlight and heaters.
・Be sure printer ventilation ports are not blocked.
・Do not operate the printer in a humid or dusty environment.
・Use an outlet that is separated from noise-generating equipment such as motors.
・Use the correct AC voltage to avoid unexpected problems.

20
2.3 Unpacking
Unpacking the printer as follows(Figure 2.1)
1. Open the carton and remove Ribbon cartridge and Cushion L/R.
2. Lift up the printer using the grip at right and left of the printer.
3. Take out accessories (Power cord, Manual).
Figure 2.1 Unpacking the printer and accessories
