1. Power unit reset and control panel reset switch:
If the

AC

ower goes below

83-87%,

the internal reset circuit is activat-

ed and holds all scale and printer operations are terminated.
In the same way, the control panel reset switch resets the internal cir­cuits. Therefore, this reset switch is used to recover after a malfunction.

2. Fuses
Glass fuse (5A: 100N/115V, 3A:220V/240V). Note: there are no fuse.s in-

side the power unit.

3.

Label advance motor

The AC-2000 uses a stepping motor to advance the labels. rotation and
stability can be precisely controlled.

Also since rotation speed

is

syn-

chronized with the print signal to the thermal head, the print quality

is

stabilized.

ELECTRICAL CONFIGURATION

THE AC-2000 uses

2

types of fluorescent displays: full dot matrix and 7-segment.

The full dot matrix display is used for displaying' alphabetical messages. The

7-

is

used.

ELECTRICAL CONFIGURATION

The peeling sensor controls label issue. The set cassette no. and label size de­termines tahe amount of label advance.

NOTE:

During label printing, if there is no label pqeling operation, the next la­bel will not be printed. Label peeling

is

only activated during label

printing (according to cassette number). During receipt printing the

signal

is

disregarded.

Purpose

In order for the thermal head to print out a line, the head's line and the top line
of the print roller must be aligned to the same position. If misaligned ,the en­tire width of the line will not be printedclearly. By adjusting the installation po­sition of the thermal head, this adjustment can be made.

2.

Adjustment Method

Loosen the

head screws, and align the thermal head and sii htly retighten

3

the screws. The head should be aligned so that the the printe characters are

sufficiently and consistently darkthroughtout a line. Finally, tighten the head
screw.

If ink, glue or dust from the label gets stuck to the thermal head print surface,
heat will not be properly transferred to the label causing poor print quality.

The print roller drives the label feed. If dust from the label gets stuck to the

roller,

it

could cause improper label feed.

NOTE:

Clean with the attached cleaning pen dipped in filtercleaner.

When the cleaning pen and filter cleaner are not available, wipe with a

clean cloth moistened with benzene.
When cleaning the head be.very careful not to scratch or damage it.

Never use thinner for cleaning the head.

LABEL FORMATTING: USA

It is possible to modify label formats or move printed contents to comply with the

customer's requirements. The location data

is

stored in

E2

PROM so there

is

no need

to change

it

via.PROM Writer.

NOTE: Transaction labels or total label printing formats are subject to Weights and
Measures approval.

A

change of format or deletion of printed information may re-

sult in non-compliance with Weights and Measures regulations. Please use the ut-

most caution when changing or modifying the printing format.

This section will describe the actual dot printing size and coordinate setting.

The

AC-2000

is

equipped with a double density type thermal head, but labels are

printed at double density. Printing coordinates are

set

using double density specifi-

cations. Single density dot

size

is as shown below:
