The information contained in this Service Manual and the Printer

Technical Bulletins is essential to proper maintenance of the

ColorCoder V4 printer.

This Service Manual is supplemented by the following publica-

tions, which the service technician also should keep easily avail-

able:

• Intermec ColorCoder V4; User's Guide (multilingual)

• Intermec ColorCoder V4; Installation & Operation manual

• Intermec ColorCoder V4; Spare Parts Catalogue

Please note that the operations described in this manual only should

be carried out by skilled and authorized personnel with proper

training and full understanding of written English. The printers

contain wires and circuits with high voltage, which implies the risk

of electrical shock. Moving parts may also cause harm, if incor-

rectly manipulated.

1. General Description

1.1 Features

This product is the world's first 4 inch wide, high speed Color Label

Printer employing the bubble jet printing process, and has the

following features.

1. By using four 4-inch wide bubble jet (BJ) line heads (Y, M, C,

K) in its printing head, it is able to produce full-colour printing

at high speed (150 mm/sec.) and in fine detail (360 dpi).

2. Head shading utility software is developed to correct ejection

error of each BJ head nozzle. Further high quality of full-colour

image is realized.

3. Four types of English language fonts are available as built-in

fonts. In addition to that, it has a function of font download from

a host computer.

4. It has a bar code printing function, and is able to handle eight

types of bar codes.

5. Is has a partial rewrite (overlay) function, which enables it to

change part of the data with no need to stop printing.

6. Ink recycle system newly installed, taking waste ink generated

through BJ head cleaning operation, and put it back into ink

supply system to reuse it for printing. It saves both ink and

running cost.

7. By employing high durable and reliable parts, the necessity to

assign parts as periodic replacement or consumable parts has

been minimized.

8. It has a handy cutter as standard equipment thus making label

cutting work more efficient.

9. A roll unit is provided for the paper feeding. By setting a large

roll of paper, consecutive mass-printing is possible. By remov-

ing the roll unit drive system, fan-fold paper can also be used.

2. Operation and Timing

2.1 Basic Operation

2.1:A Functional Construction

The printer can be divided into interface system, control system,

image formation system, and pick up/feeder system in terms of its

functions (see Figure 2-1).

The printer has the plural printing data acquiring routes, any of them

being acquired through the system interface system.

The printing data are developed to an equivalent of one page of the

image data in the image processing unit, and then printing operation

starts.

When the printing operation starts, the BJ head is initialized,

commencing paper pick up. The printing position of the paper is

counted after the TOF inlet sensor detects the TOF mark on the

paper (or the gap between the labels). Printing operation will take

place after the image processing unit sends an equivalent of one line

of the printing data to the image formation unit at the time when the

printing position reaches the black head. Transmission and printing

of an equivalent of one line of the printing data are repeated in

synchronization with the feed of the paper to perform black

printing. From now on, each time when the label reaches the cyan,

magenta, and yellow heads, transmission and printing of an equiva-

lent of one line of the printing data are repeated for each colour,

completing an equivalent of one page of colour printing.

The printer consists primarily of a formatter PCB and engine 1 and

2 PCBs. Major functions of each PCB are as follows:

• Analyzes the command data emulation

• Develops the printing data to image memory

• Controls the control panel

• Controls the roll holder unit

• Controls the option (cutter unit)

• Controls the output from the power supply unit

• Interfaces with the engine control unit

Engine 1 PCB

The feeder system and the ink supply system are controlled by a

microprocessor and a special gate array.

• Controls the feeder system

• Controls the ink supply system

• Clock function

• Backup memory function

• Interfaces with the formatter PCB

Engine 2 PCB

All about the BJ heads and the PHS unit, such as cleaning, are

controlled.

• Controls the image data transmission of the heads

• Controls the head drive and temperature

• Controls the head motor

• Controls the cap motor

• Controls the fan motors

Figure 2-2 is a block diagram showing the printer’s major circuits.

The electrical control of the printer is executed by two microproc-

essors each installed on the formatter PCB and the engine 1 PCB,

respectively.

The printing data read by the memory card or Parallel interface from

the host computer are image-processed on the formatter PCB, and

sent to the BJ line heads via the engine 2 PCB at the time of printing.

Feeding of the paper and supply of the ink are controlled by the

engine 1 PCB.

Inside the PHS unit are arranged two motors and one solenoid,

which control the UP and DOWN motion of the head holder unit

and capping and wipe evacuation operation of the recovery unit.

These are controlled by the engine 2 PCB.

Chapter 2 Operation and Timing

The feeder unit is provided with a motor and four paper detection

sensors, and the pump unit is provided with a pump motor, solenoid,

and three electromagnetic clutches.

The power supply consists of +12 V, +5 V, –12 V, and +24 V

systems, and the power is supplied to the BJ head, motors, and

solenoids in addition to each PCB.
