Thermal Label

Printer

The thermal label printer (also referred to simply as the labeler) uses a

thermal print head to print labels. The labels are supplied on a roll of

label liner that is threaded through the labeler assembly from a label

supply reel. The number of lines that the labeler can print on a label is

determined by the size of the font selected.

The label drive motor is the only motor mounted behind the labeler

assembly plate. It provides the drive to turn two rollers that advance the

liner through the labeler system as well as two rollers that advance the

ribbon through the labeler system. The black pinch roller snaps into

position to assist the label drive roller to get a firm grip on the label liner.

The timing of the label advance roller has to be precise so it can

accurately place the label on the device and ensure even spacing between

the printed characters on the label.

The 2500 lets you choose the position of the label on the device. In order

to accomplish this, the labeler must know the location of the labels on the

liner and must be able to advance the label so it contacts the device at the

correct time. On the front of the labeler assembly plate, the ADC optic

detects the leading edge of the label. The highly sensitive ADC optic

emitter/collector pair reads the level of light that passes through the

combined label and liner during label calibration. This light reading,

called the ADC optic value, is the reference level used to detect the

increased level of light passing through the liner alone. This reading

allows the labeler to synchronize with the leading edge of the labels.

Character Sizes

The labeler can produce six font sizes, measured in characters per inch

(CPI). The six font sizes are listed below (firmware version 1.24 or higher).

• Normal Fonts: 11, 16, 19, 22, and 28 CPI

• Short Font: 28 CPI

Programming

Electronics Boards

and Assemblies

The PE is composed of two main units that are mounted on the underside

of the handler’s main plate at the programming station.

The PE’s major assemblies are described in the following section.

•

Power Supply

—The input AC generates +15V DC that is routed to

the controller/waveform board’s internal power supply circuits.

•

Controller/waveform Board

—Uses +15V (from the power supply) to

generate a precise +10V reference. This reference acts as an input to

12-bit DACs that help generate numerous voltages (+/- 5V DC, +/-

8V DC, +10V REF, +13V DC, -15V DC, +25V DC, and +36V DC) for

use primarily on the pin driver board(s). The center of the controller

circuitry is a 68000 microprocessor that controls system operation

using 64K of Flash EPROM, system RAM, and 8 MB of user RAM.

Two RS-232C ports are located on this board and use the PE’s

SmartPort software feature to toggle the cables DTE and DCE lines

until a connection is established.

The floppy disk controller provides the signal interface between the

main system and the disk drive. A special circuit called the pin

control unit (PCU) acts as a coprocessor that controls read/write and

timing signals to the pin driver boards. A 68-pin and a 50-pin cable

carry control signals and supply voltages from the control unit base

to the pin driver board(s).

•

Mass Storage Module

(MSM) — The internal hard drive. Under the

default configuration for the 2500, algorithm files are automatically

installed on the MSM when you update system software. The MSM is

partitioned into 4 logical drives:

•

User data drives C

and

31MB and 512 maximum files each.

•

System data drives H

and

: 7MB and 10MB respectively with 320

maximum files each. Reserved for operating system files.

•

Disk Drive

—Double-sided, quad-density (1.44 MB formatted), 3.5-

inch disk drive reads the PE system disk to load updated commands

into system RAM and the MSM. It can also be used to load data files

into user RAM.

•

Relay Board

—Controls the flow of signals between the controller/

waveform board and the pin driver board(s). Cables from the

controller unit connect to the pin driver head through the relay

board. These signals are routed to the pin driver board(s) and then

through the relay board to the device to be programmed. Relays on

this board are energized to provide hard V

and GND levels to

device pins as required by the programming algorithm.
