5/64 Adjustment Screws
Validation
A Validation Form can be inserted from the top or top and left once the clamp has opened. The
printer will automatically clamp the form when it has been detected. Wait until the printer has
nished printing and released the form prior to removal.
Adjustable Features
Air Gap Adjustment
The air gap may need adjustment if 3 ply roll paper is used. If adjustment is required it will be
evidenced by ink smudge on a Self Test printout. Most 3 ply paper can be accommodated by
turning the 2 adjustment screws clockwise 1/8 of a turn.
A470 Users Guide
CAUTION: Metal surfaces of
printhead may be hot - avoid
contact! The air gap is the
distance between the print head
and the print bar. This space must
be large enough to accommodate
the ribbon material and the print
media. Too great an air gap will
cause light print or missing dots
and too small an air gap will
produce ink smudge on the media.
The air gap can be changed by
turning the 5/64 hex socket drive
screws near each end of the print
bar. These screws are visible
once the cover is raised and
the ribbon cartridge is removed.
Clockwise adjustment will increase
the air gap and counter-clockwise
adjustment will decrease the air
gap.

Document Stop Adjustment
The Document Stop limits the depth an inserted form can be placed into the Validation Slot. This
denes the validation printeld height. Printers are manufactured with the maximum printeld
setting of 2.16 inches but the dimension can be reduced to 1.44 inches by turning a slotted
screw in the bottom of the printer case counter-clockwise (CCW). Each CCW revolution raises
the document stop and decreases the printeld height 1/32” (.03125”) or .79375 mm. DO NOT
ATTEMPT TO ADJUST THE DOCUMENT STOP OUTSIDE THE PRESCRIBED LIMITS OR
DAMAGE TO THE PRINTER COULD RESULT. The validation form must be at least 1 inch taller
than the selected printeld.

Clockwise rotating lowers the
document stop and increases the
print eld.
Counter clockwise rotation raises
the document stop and decreases
the print eld.
Verication of the desired document stop setting can be made by printing a Self Test on
validation media and measuring the printeld. A Self Test is initialized by turning the printer
power off, inserting a form, and turning the power back on. The validation rollers can be
opened manually by raising the printer cover and pressing downward on the yellow sector gear
if the printer will not accept a form. The printeld dimension is measured from the top of the
rst line of print to the bottom of the form.

Low Paper Sensor Adjustment
A470 Users Guide
The Low Paper Sensor is located on the inner-frame to the right side of the paper roll.
This sensor is a reective optical device that can be adjusted to accommodate various roll core
diameters and quantities of paper present when low paper indication occurs. The sensor mounts
on a friction bracket and can be adjusted up or down. Lowering the bracket will cause the low
paper indication to occur earlier and raising the bracket will cause the low paper indication to
occur later.
Caution! The Low Paper Sensor will be disabled if the bracket is raised enough to “see” the
paper roll core.
Pertech® 2006

Maintaining The Printer
There is no customer maintenance required for the A470 printer, however, you may
occasionally clean lint and paper dust out of the mechanism using low pressure canned air. It is
recommended that this is done on a regular basis, such as after every ribbon change. Clean the
cabinet as needed to remove nger marks and dust. Use any household cleaner designed for
plastics, but test it rst on a small, unseen area. The cabinet nish and materials are durable and
resistant to the following:
Cleaning Solutions
Lubricants
Fuels
Cooking Oils
Ultraviolet Lights
Caution: Do not spray or try to clean the printhead or the inside of the printer with any kind of
cleaner. This may damage the printhead or the electronics.
A470 Users Guide
Printers gather paper dust and other debris through normal use. Continued accumulation will
eventually prevent operation of the printer. A preventive maintenance program can help reduce
unnecessary failures and downtime. Pertech can offer a regular service program to meet your
needs. For more information call 800-800-6614.

Flow Control

1
The RS-232 interface uses either XON/XOFF(Software) or RTS/CTS (Hardware) protocol. This
is set via dipswitch A 7. For the selected serial interface Flow Control of XON/XOFF, a particular
character is sent back and forth between the host computer and the printer to regulate the
communication. For RTS/CTS, changes in the RTS/CTS signal coordinate the information ow.
Parallel Interface
The Parallel interface is compatible with IEEE 1284 Parallel Interface Standards. Using the
Parallel interface with the printer requires that you set Dip Switches A1, A2, A3 to the Closed
position.

Chapter 5: Trouble Shooting Printer Problems
Trouble Shooting General Issues
Following are symptoms your printer may exhibit and simple
solutions the printer operator could implement.
• Printer failed to print after the roll paper was replaced.
The top cover must be closed for the printer to print.
• The power switch is turned ON but the printer is dead. The Green Power LED is Off.
Make sure the outlet has power and the power cord is plugged into the
back of the printer.
• The printer will print a Conguration Report but will not respond to the system commands.
Check to see that the interface cable is connected to the back
of the terminal/ PC, and to the back of the printer.
• Printer prints too light to read easily.
Replace the ribbon cartridge and check the Air Gap adjustment. See Chapter 2 Operating the Printer \
Adjustable Features \ Air Gap Adjustment.
Call 1-800-800-6614 to order new Ribbon Cartridge’s’.
• Flashing Red Power LED indicator.
Lid open or paper is low/out.
• System reports low paper even though the roll is nearly new
See Chapter 2 Operating the Printer \ Adjustable Features \ Low Paper Adjustment.
• Colored stripe on the receipt.
Paper Low, adjust the paper low sensor, replace
the paper. See Chapter 2 Operating the Printer \
Adjustable Features \ Low Paper Adjustment..

• Receipt does not come all the way out.
Printer is jammed.
To remove paper that has jammed, it is
advisable to:
1) Tear off any paper that fed out of
the top of the mechanism
2) Press downward on the metal
release bracket
3) While pulling the remaining
paper out of the mechanism
backwards
• Status light is Red (not Green) and printer will not respond.
Remove the ribbon cartridge and paper roll. Using Low Pressure Canned Air spray out the
areas around the three sensors. (See Illustration below).
• Printer prints when the Power is turned On even though the form is not inserted.
Spray air in the validation slot and make sure no paper pieces are blocking the sensor.
Form In Sensor
There are three sensors in the
area directly under where the
Ribbon Cartridge is installed.
Check these to make sure that
they are free from dust and
debris. Reinstall the Ribbon
Cartridge and Paper. Close the
Lid and Print a Conguration
Report. If the Status Light
remains red see “Fault” later in
this chapter.

Fault Mode
A470 Users Guide
The printer will enter a Fault Mode and will not operate when certain failure conditions are encountered. Conrmation of this condition can be accomplished by the host on the DTR (pin 8)
or status with an RS-232 interface, or on the printer fault line (pin 15) for the parallel interface.
A Printer in Fault Mode will not feed paper when the paper advance button on the top
cover is depressed nor will it execute commands other the Reset <ESC><NUL> or Status
<ESC><ENQ>. A parallel printer may indicate a fault when roll paper is low or out but is not in
Fault Mode. Make sure the roll paper is present when conducting this test if DIP switches A1,A2,
& A3 are closed ( parallel Interface selected) and switch A8 is Open (Fault On Low Paper).
The color of the LEFT LED on the front panel of the
printer will change from Green to Red if a fault condition
is encountered. Depressing the paper feed button on
the printer cover will cause the printer to enter diagnostic mode. This will cause the LED to ash a 3 bit code
to dene the specic reason the printer entered Fault
Mode. The error code is followed by a delay before being repeated. The diagnostic code will toggle the DTR
line and ash the Red LED if the RS-232 interface is selected. It will toggle the Fault- line and ash the green
LED if the parallel interface is selected.

DOTS / LINE dots per line - number of dot columns used within the 400 dot printeld - a product of
dot columns (To) and CHARS / LINE
The normal fonts are 5 or 7 dot columns wide (Ch) and the Double Wide fonts are 11 or 15 dot
columns wide (2x + 1). No single dot can re on adjacent columns, i.e. a font which is 7 dot columns
wide will not activate any single dot more than 4 times (positions 1, 3, 5 & 7).
The printeld is 2.78” wide and has 400 dot columns, each .00694” apart horizontally. Some pitch
selections do not utilize the full printeld width and terminate after the last character which can be
completely printed. All lines are left justied.
This printer employs a 9 wire impact print head, however, most characters are printed with the top
7 wires. The bottom 2 wires are used for printing the descenders on the g, j, p, q & y and when text
is underlined.
