“Shock Hazard,” is defined in Underwriters
Laboratories Radio and Television Receiving
Appliances Standards for Safety. 12th ed., 25
June 1969:
“Shock hazard shall be considered to exist at any
part involving a potential of between 42.4 Volts
peak and 40 Kilovolts peak in the following cases:
A. If the current through a load of not less than 500
OHMs exceeds 300 milliamperes after 0.003 second.
B. If the current through a load of not less than 500
OHMs exceeds 5 milliamperes after 0.2 second.
C. If the time required for the current through a
load of not less than 500 OHMs to decrease to 5
milliamperes is between 0.1 and 0.2 second, and
the total quantity of electricity passed through the
load up to that time exceeds 4 millicoulombs.
D. If the time required for the current through a
load of not less than 500 OHMs to decrease to 5
milliamperes is between 0.03 and 0.1 second, and
the total quantity of electricity passed through the
load up to that time exceeds 75T-350T

2.1OPEN FRONT PANEL
The printer's front panel must be opened for
access to the internal printer assembly. In order to:
Change Printout Variables (2.2)
Change Interface (2.3)
Turn Battery Backup On or Off (2.4)
Load Paper (2.6)
Change Ribbon (2.7)
HOW TO OPEN THE FRONT PANEL . . .
(refer to Fig. 1)
1. Open the front panel by pushing in the locking
fasteners on either side of the front panel. (Front
panel will flip down after fasteners are pushed in.)
2. Pull front panel away from unit until it stops.
3. At this time, you have access to the internal
printer assembly.
2.2CHANGE PRINTOUT VARIABLES
The variables that determine printout format (how
data prints out) are factory-set but can be
changed during installation. The factory settings
(default settings) are:
VARIABLEFACTORY SETTING
Font*Normal
Print Direction*Normal (first line down)
Word WrapON
Calendar FormatStandard (mo/day/yr)
Baud Rate300
Data Bits7
InterfaceStandard (RS-232-C)
Battery BackupON
*These printout variables can also be changed
using Escape Commands from a remote terminal.
NOTE: However, that variables changed by
Escape Commands are not saved in memory
when the unit is turned off. Only changes made
during installation, while the unit is turned off, are
saved.
HOW TO SELECT PRINTOUT VARIABLES...
Printout variables are selected by adjusting the
positions of the 5 position S1 and S2 DIP switches, which are located on the Main Logic Board
(found by opening the front panel).
NOTE:
1. Before adjusting the DIP switches, TURN OFF
ALL POWER. Switches are checked only on
power up.
2. DIP swithces are very tiny. Use a small, pointed
instrument to adjust swithces. Be careful not to
disturb adjacent settings.

2.2.2SELECT PRINT DIRECTION
2.2.4SELECT CALENDAR FORMAT
On many printers, data prints out upside-down
(first-line-down/NORMAL) while this presents no
problem once the printout tape is removed from
the printer, it can be difficult to read if the printout
is of immediate interest. With the 6610 printer you
can select the NORMAL print direction (first-linedown) or an INVERTED print direction (first-lineup).
Word Wrap accommodates long lines of data without hyphenation. When word wrap is selected, the
printer can print the same amount of information
as an 80-column printer, but without special formatting.
When Word Wrap is ON, the printer automatically
executes a CR LF (carriage return, line feed) at
the first space prior to printing the 25th character.
When Word Wrap is OFF, the printer executes a
CR LF as the 25th character after receiving 25
characters without a CR LF.

(Printout: 00:30:00 INTV
__:__:__ SYNC)
The Interval Print feature of the Clock Option
enables printing at a pro-set Interval Time (INTV).
INTV tells the printer to send a time-to-print signal
to the host computer system.
NOTES:
(1) The Interval Time causes the printer to generate a signal only; it does not cause the printer to
print.
(2) If INTV is programmed with some number >59
(for seconds), >59 (for minutes), or >23 (for
hours), nothing will happen. The printer will not
print an error message or the numbers that were
entered.
(3) Interval output will not function properly at
9600 baud.
TO CLEAR INTERVAL TIME ...
1. Press: <M> and <3>.
2. Than press <000000> (6 zeros)
(Printout: INTV CLEAR).
IMPORTANT: If power is lost between interval
times, the first interval time on power up could be
twice as long as it should be. Additionally, if a 1second interval time is programmed and power
fails, it is possible that when power returns, the
real time clock and interval time will be set equal
to each other. This means the 1-second interval
time will not resume for 24 hours.

EXAMPLES: Ex
ecute the
“Print Clock” function,
using Control Commands:
NOTE: The 2 examples provided here include
both time and date. Either may be printed independently by omitting either the date or clock command.
NOTE To 6612 and 6614 Users: These models will
function as descr
ibed below; however, because
they can print more characters per line, they have
additional capabilities. Soldering together solder
pad SP3 on the main logic board (see lower right
corner of the board layout shown in the figure on
the next page) will enable the 6612 and 6614 to
print Date, Time and Data on a single line, instead
of requiring two lines.
EXAMPLE 1: PRINT CLOCK AS HEADER
To print the clock and date as a header before a
block of data, simply transmit to the printer:
1BH, 54H, 20H, 1BH, 44H, 00H, 0AH
