470 Operators Manual
Introduction
The Microcom 470 is a Direct Thermal or Thermal Transfer label printer with a high resolution
(832 dots or 8 dots/mm), 4.09 inch wide print head. Through the use of dual high speed
processors, the printer has the ability to handle a wide variety of labeling tasks - even the most
demanding applications.
The resident Label Design Software (LDS) is a powerful and easy-to-use package that allows
you to create personalized label formats. It can be driven from a PC, mini-computer,
mainframe, and most special purpose computers.
Among many other features, LDS supports downloadable graphics and fonts, multiple serial
numbering, and flexible character kerning. It offers virtually unlimited text font sizes and all
popular bar code symbologies. Graphic images can be printed or stored in the printer's
memory for future use. Bitmapped Fonts, bar codes, and graphic images can be multiplied in
size and printed in 0,90,180,270 degree rotations. To offer even more flexibility, our new
scaleable or "Vector" fonts and lines can be rotated in one degree increments. Once the labels
are designed, they can be stored in the 470's memory for high speed printer access.
The 470 is capable of printing on most types of label stock or fax paper. It offers operation in a
tag/tear, peel-and-dispense, batch mode, and user-defined advance mode. It can handle blowhole, black-line, label gap, and continuous stock.
Many printer applications use the same label format, but change the data on every label. This
is not a problem for the Microcom 470 printer. Data may be changed without down-loading the
same fixed format, or fixed data fields, time after time. This, along with a greatly increased
communication speed, increases data access time and productivity.
Microcom also offers a complete line of software packages which allow quick and easy onscreen label designing, along with complete database capabilities.

2.1 UNPACKING THE 470 PRINTER
While unpacking the printer, please check all packing materials closely to avoid misplacing any
necessary parts. After the printer is removed from the box, verify that all parts are present and
in good condition (see Figure 3). All packaging material should be kept and used if the printer
is to be shipped. The printer must be returned in the original container to insure proper
warranty coverage.
Printer Parts figure 3
2.2 MOUNTING THE LABEL SUPPLY RACKS
Position the printer so that the rear is assessable. Refer to Figure 2 and note the mounting
positions of each rack. Notice that the bent flanges point inward. Using the thumbscrews
provided, attach the racks to the printer.
2.3 INITIAL POWER UP
Before connecting the printer to a power source, verify that the voltage selector, located on the
rear of the printer, is set correctly. If not, open the selection door and rotate the cylinder until
the correct voltage is shown.
Plug the printer in and turn the power switch on. The back lighted LCD should illuminate and
temporarily display 'ASSUMING DIRECT THERMAL' or 'ASSUMING THERMAL TRANSFER'. If
this does not occur, check the power source and if necessary call your service organization.

2.6 LOADING MEDIA
The following two sections explain the dispensing modes and printing methods. Refer to
figures 2 and 5 for the printer components. If narrow stock is used (3.5 inches wide or less), it
may be necessary to adjust the printhead support screw (see section 2.8).
Thermal Transfer Note:
The 470 will, on power-up, automatically sense a loaded ribbon and select thermal transfer
mode. Please note that the printer will not select thermal transfer mode if the ribbon is loaded
after the printer is turned on. To correct the situation simply cycle the power once the ribbon
has been loaded.
2.6.1 NORMAL AND TAG/TEAR MODES
Place the label supply shaft and stock onto the wire rack. Raise the print head with the lift lever
and insert the paper with the thermally sensitive side up. Follow the loading diagram and
thread the paper through the printer and under the print head. Lower the head lift lever and
you are ready to print.
2.6.2 PEEL-AND-DISPENSE MODE
Follow the paper loading in the normal and tag mode directions. Pull out several inches of
paper and remove the labels. Be sure the leading edge of the stock is flat and square. Rotate
the pinch roller release knob and insert the paper between the black drive roller and the white
pinch roller. Remove the slack and release the pressure on the pinch roller by turning the
release knob.

2.7 RIBBON SELECTION
Many different ribbons can be used with the 470. However, to extend printhead life and
achieve quality results, it is necessary to correctly match the ribbon to the receiver stock.
Incorrect matching can cause premature printhead failure. Please contact Microcom
concerning recommended media and compatibility.
2.8 PRINTHEAD SUPPORT ADJUSTMENT
When using narrow media, less than 3.5" wide, it is possible to increase print quality and
prevent premature drive roller wear by correctly adjusting the printhead support screw. To
make the adjustment, simply turn the head adjustment screw (see figure 5) clockwise until the
printhead is slightly lifted from the drive roller. Once the head has been lifted from the roller,
verify that the print head has not been lifted too far by printing a test label. If the print quality
on the right side of the label appears weak, then lower the printhead by turning the thumb
screw counter clockwise until the print quality is corrected. If the quality problem appears on
the left side, turn the screw clockwise until the print quality is corrected.
2.9 CLEANING INSTRUCTIONS
The 470 printer and printhead should be cleaned approximately every 7,500 inches or every
two weeks whichever occurs first. The printer should also be cleaned whenever you run out of
label stock. Proper cleaning assures that any adhesive that may come off the end of the
previous roll, is removed. A Microcom cleaning kit (part #040005) should be used for cleaning
and maintaining a Microcom printer product. It is important to note that optimum printhead life
is achieved by cleaning the printer and printhead.
To clean your Microcom 470 printer:
1) Turn the printer off.
2) Lift the printhead using the lift lever at the rear of the printer and remove any label
stock that remains inside the head mechanism.
3) Using the cleaning brush, sweep away all small label and adhesive particles that may
be in the area of the printhead.
4) Moisten a cleaning swab with the cleaning solution and wipe away any adhesive from
the rollers or the aluminum peel bar.
5) Dampen a swab with cleaning solution and lift the print head. Take the moistened swab
and gently wipe the underside of the printhead. Repeat if necessary (if swab is
extremely dirty).
6) Moisten the felt side of a cleaning card with the cleaning solution. Raise the print head
and insert the cleaning card under print head with the felt side facing up. Lower the
print head and press the feed key to feed the card through the printer. Allow the
printhead to ride on the cleaning card. Repeat the process if needed. The cleaning card
may be used once at each end.
WARNING: DO NOT TOUCH THE PRINTHEAD WITH ANY METAL OR SHARP OBJECTS

470 Operators Manual
CHAPTER 3: COMMUNICATIONS
The 470 is very versatile. It can be interfaced to PC's, mini-computers, main frames, and
special purpose machines. It is capable of serial RS-232-C, Centronics® parallel, and
optionally RS-422/485 serial communication. The following sections explain the communication
interfaces.
Out of the box, unless otherwise requested, the Microcom 470 communicates using serial RS232-C at 9600 baud, 8 data bits, 1 stop bit and no parity with both hardware and software
handshaking. This configuration may be changed as shown in Appendix E.
3.1 CABLE PINOUT
Table 1 shows the signals of the 470's 25-pin RS-232 serial port and table 2 shows the parallel
port configuration.
If serial RS-232-C communication is selected and XON/XOFF hand shaking is used, the only
signals the 470 requires are the RXD, TXD, and GND signals. If hardware (CTS) hand shaking
is used, a CTS signal is provided and an RTS signal is required. XON/XOFF may be disabled
through software dip switch #1 (see chapter 5). The other signals are offered in the event the
host computer requires these signals.

CHAPTER 4: DESIGNING LABELS USING LDS
Label Design Software (LDS) refers to the software resident in the printer used to decipher
label formats sent by the host computer. All fonts, character sets and bar codes symbologies
are resident in the printer.
A label format is produced by a series of 5 steps:
1: Control commands to define printer operation
2: A header to define label height, width, print speed, etc..
3: Field data to define placement of text, bar code, graphic or line
4: Actual text data to place in the above text or bar code fields
5: Control commands to initiate printing
4.1 CONTROL CHARACTERS
Throughout this manual there are references to control characters. In order to print them in this
manual, they have been written using standard characters and icons. Escape characters are
represented by <ESC> and a carriage return is represented by the 5 symbol. It is important to
note that all printer functions, unless otherwise noted, must be followed with a carriage
return5.
4.2 GETTING STARTED
There are many different machines that can send information to the 470 printer: For example main frames, mini-computers, special purpose computers and PC's. However, if you are using
the printer for the first time, the easiest way to start is with a PC and a terminal emulation
software program. This will allow two-way, serial communication with the printer. You will be
able to quickly upload files and access label-sizing and other features that will help
considerably in formatting your first labels.
4.2.1 PC CONNECTION (SERIAL)
Items required:
- A computer with at least one unused serial communications port. (COM1,COM2...)
- A serial interface cable. (See section 3.2 for cable information)
- A terminal emulation program. (Procomm, Telix, Windows terminal...)
Note: This communications test assumes that you have a standard serial 470 printer.
Set the communication parameters in the PC terminal software program to 9600 baud, no
parity, 8 data bits and 1 stop bit. Unless modified by the user, this is the printers'
communication configuration out of the box. Depress ^C (ASCII or control code) on the PC
keyboard. If the printer prints a label, proper PC to printer communications have been
confirmed. Depress ^E to verify printer to PC communication. You will receive a text response
from the printer.
If a terminal program is not available, it is possible to send files to the printer using the DOS
COPY command. To do this you must first create a text file containing the information to be
sent (i.e. ^C ). You may use any text editor that does not add its own formatting characters
(QEDIT, Wordstar non-document mode, DOS 5.0 EDIT, EDLIN...).

You may use any text editor that does not add its own formatting characters (QEDIT, Wordstar
non-document mode, DOS 5.0 EDIT, EDLIN...). Send the file to the printer using the following
DOS command. Note: LPT1 may be any available printer port on your PC.
C:>COPY FILENAME LPT1
4.2.3 LEARNING LDS
You can test some of the control code functions (see section 5.1) directly through the
keyboard. Large label files, such as some of those illustrated in Appendix B, may be entered in
a straight ASCII text word editor and then up-loaded to the printer using a terminal emulation
program or the DOS copy command. (To use the DOS copy command, first use the DOS
mode instruction to configure the PC. For example, MODE COM1:9600,N,8,1,P).
There are some special features offered by the 470 printer that will aid in label design. For
example, the autosize command (^A2^D395) will provide most of the header format
information needed to define the different properties of label stock. The state of the machine is
accessed through the enquiry command (^D55 or ^E). The statistical printer information is
made available through the ^A0^D295 command.
The following sections of this chapter are designed to give an overview of a label format,
define the label header, and list the different types of field information available. Chapter 5
explains the special functions of the control codes. Once some understanding of these basic
concepts are achieved, use the quick reference guide in Appendix D for expedient label
design.
4.3 FORMATTING LABELS: AN OVERVIEW
A label format consists of a header record and field records, followed by the text data to be
printed. The records describe how the label is to be printed. The header contains information
about the label itself such as label height, width, print speed, etc. The field records refer to the

data section and contain information about positioning coordinates, the type of character
generators or bar codes to use, etc.. Below is a sample label format. We will refer to this
format as we break down the components of its structure.

The sequence ^D575 puts the printer in format entry mode.
The next line is the header information: sizing the label (812 dots wide 609 dots high).
The next four lines are layout information for each data field in the format.
The sequence ^D565 selects the user layout.
The sequence ^D25 tells the printer to start accepting data for each defined field. (Field #1
defines where Data #1 should be positioned.)
(Note: The label prints from bottom to top.)
The next three lines are data for each field.
Text string #3 is accessed twice. The format will print the word 'EASY' and then the bar code
equivalent.
The sequence ^D35 starts the print cycle. (Default is one copy. See section 5.3.2)
4.4 LABEL HEADER
The header consist of eleven parameters. These parameters contain information about the
label. It is not necessary to enter information for all of the parameters: If a parameter is left
blank, then the default value will be used. A carriage return must follow the label header
parameters.
The value of measurement for many of the header elements is the dot. There are 203 dots per
inch on a 470 print head (8 dots/mm). There is a maximum 832 dots in the X direction (width).
The Y direction (length) is 4060 dots or 20 inches long. (The print length is virtually unlimited in
Epson® mode ).
Most header parameters can be supplied using the autosize command. (See section 5.3.3.)
Below is a list of the header element mnemonics and their default values:
HFM, LSX, LSY, WEB, GAP, DPS, LCB, AGD, SPG, OFX, OFY

Refer to Figure 7 for a visual representation of most header parameters.
The following is a description of each header element:
HFM NUMBER OF FIELDS IN LAYOUT
This parameter is used to specify the number of fields in the layout. If more fields are
defined than what is specified for HFM, the extras will be ignored. To prevent software
confusion, do not set the HFM parameter to a number higher than the number of fields
defined.
LSX LABEL SIZE X DIRECTION
Specifies the width of the label in dots. For example: A 3" wide label would have an
LSX of 3 x 203 = 609 dots. (203 dots = 1 inch)
LSY LABEL SIZE Y DIRECTION
Specifies the height of the label in dots. (maximum of 4020 dots)
WEB WEB SIZE
The width, measured in dots, of the webbing that is found on the left side of the label.
GAP GAP SIZE
The height, measured in dots, of the gap between labels. Autosizing (See section
5.3.3) will define this value.
DPS PRINT SPEED
The speed the printer prints a label. Generally, better print quality is obtained at lower
print speeds.
The labels per minute a particular format will print can be calculated by the equation
below:
IPS x 60 seconds
Labels per Minute = -------------------------- Label Height
The printer's default print speed is 3.2 inches per second (DPS value = 48). To speed it
up or slow it down, the following DPS parameters can be inserted into the label header.
Note that a higher value slows the printer down and a smaller value speeds it up.
See Table 3 for a list of print speeds, DPS values, and inches per second.

LCB LABEL CONTROL BYTE
This parameter selects between the various gap detection methods.
Continuous Stock: If set to a value of 2, the printer will not activate the gap detector
circuit. After all fields are printed, the printer will advance the extra distance in the SPG
header element.
Normal Stock (leading edge): If set to a value of 0, the printer will detect the leading
edge of the label (the start of the next label).
Black Line Stock: If set to a value of 1, the printer will detect the leading edge of a black
line.
Blow Hole Stock (Slot-Cut): If set to a value of 0, the printer will detect the leading edge
of a blow hole (see software dip switch #4 (^D24) for blow hole stock).
AGD NUMBER OF STEPS TO ACTIVATE GAP DETECTOR
This parameter selects the number of steps (dots) that the printer should skip before
gap sensing is activated. This value is usually defaulted. It is not defaulted when using
stock that contains pre-print or gaps that may cause the gap detector to trigger
incorrectly.
SPG NUMBER OF STEPS PAST GAP
The number of steps to advance the label after detection of a label gap. Use autosizing
(See section 5.3.3) to quickly evaluate this parameter for small stock.
It may also be necessary to adjust this value if using material with a sense position not
located at the end of the stock.
The 470 uses the following formula to determine the SPG setting:
If label height is greater than or equal to 580, then SPG=580
If label height is less than 580, subtract (LSY+GAP) from 580 until the answer is
negative, then add (LSY+GAP) back to become positive again. Subtract the AGD value
(usually 1) and the result will be the correct SPG.
OFX X DIRECTION OFFSET
This parameter moves all the fields in the X direction without changing the fields
themselves.
OFY Y DIRECTION OFFSET
This parameter moves all the fields in the Y direction without changing the fields
themselves.
