microcomputer's memory during the start-up self-test.
"E-FAIL" indicates a failure of the microcomputer's
eprom
memory
during the checksum test. "r-FAIL"
shows a failure of the random access memory.
Both
conditions require replacement of the micracomputer.
4.60.8
NO PRINT, FOUR SHORT BEEPS
This indicates
a print request was
made
when a valid weight is not present.
The patients
weight
must
be currently
displayed
on the scale's
readout before the printer will function, or alternately,
the "PRIOR WEIGHT" can be printed if the "PRINT"
button
is pressed
immediately
after pressing the
"RECALL" button.
A second
reason
for this problem
is if the print
pushbutton
is pressed
while a ticket is currently
printing.
If this occurs simply wait for the current
ticket to complete printing before requesting another
by pressing the "PRINT" button.
4.60.9
NO PRINT, FOUR LONG BEEPS
This is a signal to signify a problem with the
printer.
it is produced when the printer is not ready
to accept data from the scale. This usually indicates
a defective printer mechanism or interface board, or
a print head which is mechanically stuck and can not
return to the "home" {left most) position.
Check that
the printer head assembly can move freely on its
carriage.
Check for jammed
paper in the printer
mechanism.
Also check
for disconnected
cables
between
the
scale's instrument board, the printer interface board,
the printer controller board, and the printer. Note that
the flex circuit from the mechanical printer assembly
must be correctly inserted in the connector marked
"CNA"
on the
printer interface
board.
Observe
LED201
on the printer controller board, it should light
immediately when the print button is pressed.
4.60.10
PRINTER RUNS BUT RESULT IS
BLANK OR FAINT
This is generally indicative of a problem with
the
paper
used
for
printing.
This
printer
uses
"thermal" type printing paper, using ordinary plain
paper will not produce a printed result.
Also, note
that since thermal printing paper is coated on one
side only, inserting the paper upside-down will result
in a blank weight ticket.
There
are differences
between
the sensitivities of
various
thermal
type
papers,
which
can
result
in
variations of print contrast.
If a suitable local source
cannot be found order the paper directly from SCALE-
TRONIX® at the New York sales number listed in the
inside front cover of this manual.
The paper is part
number 390044 / 23709.
Inspect the printer mechanism
to ensure the print head
has not become
dislodged or otherwise separated
from contacting the paper.
4.60.11 PRINT RESULT DISTORTED, MISSING
00766)
This can be caused by a defect in either the
printer's head assembly or the printer interface board,
Check the print head
resistors with an ohmmeter.
They should measure approximately 15-20 ohms when
measured at the flexible circuit from the printer and
should
all be approximately
the same
resistance.
(Pins
1 - 8 that mates
at connector
"CNA"
of the
printer
interface
board,
resistor
common
is
pins
9/10/11.)
If the print head resistors check ok the
problem may be in the printer interface board.
4.60.12
LOW BATTERY LIGHT FLASHES
DURING PRINTING
This is caused by a battery which is becoming
weak.
The large amount of power demanded by the
printer taxes the battery more than regular weighing
use of the scale.
Some
occasional flashing while
printing is acceptable. Replace battery when possible.
4.60.13
PRINTED PAPER TICKET TEARS
POORLY, UNEVENLY
Inspect the tear bar mounted in the enclosure
top cover for signs of damage (missing teeth, cracks,
etc).
A metal tear bar is available to replace the
earlier
plastic
version
and
improve
the
"tear-off"
performance.
Check
with
the
factory
service
department
(phone number
& address
inside front
cover) for additional details.
