INTRODUCTION
This manual explains the operation of Wayne DW-10 and DW-12 thermal printers used
in Wayne Vista™ and Ovation™ fuel dispensers. The manual contains typical operator
procedures, which includes loading paper, use of the proper paper, clearing paper jams
and a list of printer precautions. The manual also contains a section on service for
Wayne certified technicians.
Once the printer door on the dispenser is unlocked and opened, the printer will appear
as shown in the photo below.
1.1 Paper Type
The recommended paper is the Wayne thermal printer paper, part number 7000701 for
1 Roll and part number 7000703 for a box of 48 Rolls. Paper used in the printer should
comply with specifications of the Wayne paper.
Other printer papers that meet our paper specification include Kansaki P-350 and
Koehler KT55F18 papers with the following:
Inside Core Diameter
.68"-.79"
Core Annular Thickness
.10"-.28"
Paper and Core Width
2.32"-2.36"
Finished Roll Diameter
3.80"-4.00"
Paper should not be stuck to the core with adhesive.
See cautions concerning paper types on the next page.

Paper Type, continued
Adhere to the cautions below when using or when storing the paper.
Caution:
Avoid allowing the surface of the paper to contact with chemicals or oils as
this may cause the paper to become colored or the printed data on it may
become erased.
Avoid scraping on the paper surface with your nail or a metal object as this
may cause the surface of heat-sensitive paper to become colored.
Do not expose the paper to the effects from heat, humidity, or sunlight as
heat-sensitive paper starts getting colored at approx. 70 degrees.

ERROR LIGHTS AND PAPER JAMS
3.1 Error Lights
Below is a description of the detected symptoms that are listed in Table 3-1 on the following
page:

Paper end:
Paper empty is detected in two steps: paper end and paper near end.
In either case, the ERROR lamp is lit. If paper end is detected, replace the paper roll.

Front door open:
If the printer door is opened accidentally, the ERROR light will go on and the print will be
continued even though the door is opened.

Head up:
The ERROR light blinks when the Head Up lever is lowered while printing. The lever should
be in the up position after clearing a jam. The print restarts automatically. The ERROR light
goes to the On state if the lever is lowered.

Thermal head over heat:
When printing dense characters or dark images, the head temperature rises. If the head
temperature exceeds a specified level, the printer stops printing and waits until the head
temperature cools off. During waiting, the ERROR light blinks slowly. When the head
temperature goes back to normal operating range, printing resumes automatically.


Cutter lock:
If the auto cutter blade stops operating due to a jam, the ERROR light blinks. Clear the jam
and press the FEED button. If the blade does not move, refer to section 3.2.

Paper jam:
When paper is fed 3 inches, the receipt sensor detects it. After the paper is cut, it is
determined to be a jam when the paper doesn't reach the sensor position at that time.
The printer memorizes whether there is paper on the receipt sensor when the print begins.

3.2 Clearing Paper Jams
If paper exit is blocked, the paper is bent and stored in the paper chute. Three receipts will
be stored in the chute before a jam occurs.
Follow the steps below and the numbered photos on the adjacent page to clear a paper jam:
1. Open the printer door. 1
2. Open the paper chute access door by pressing the door towards the rear with both
thumbs. 2 and 3
3. Remove the jammed paper. 4 and 5
4. Close the paper chute access door and the auto cutter mechanism should initialize and
the alarm should clear. Reload paper. 6
5. If the auto cutter is jammed with paper or any other reason, press the FEED button first.
6. If the auto cutter error continues, turn the cutter gear manually as shown below.
CAUTION:
The print head is hot immediately after printing. Do not touch

SAFETY PRECAUTIONS
Before using this printer for the first time, carefully read these “Safety precautions”.
Incorrect operation may result in unexpected accidents (fire, shock, or injury).
Neglecting the warnings below may result in printer failure, overheating, emission of smoke,
fire, or electric shock.
Warnings:
Do not use this printer other than for its intended application in the dispenser.
Do not use or store this product in place where it will be exposed to:
 Flames or moist air
 Direct sunlight
 Hot airflow or radiation from a heating device
 Reactive chemicals
 Airborne oil, steel particles, or dust
 Static electricity or strong magnetic field
Do not drop any foreign object or spill liquid into the printer. Do not place any object on
the printer. A metallic foreign object, if accidentally dropped into the printer, may cause
printer failure, fire, or electric shock.
Do not handle the printer in the following ways:
 Do not allow the printer to sustain strong impacts, e.g., dropping, striking with a hard
edge.
 Never attempt to disassemble or modify the printer.

Cautions:
Do not use the printer under conditions where the printer ventilation holes are blocked, where
any object is placed on the printer or where the printer is covered or wrapped by a cloth or
other materials.
The printer may have an adverse effect on nearby radio or TV transmissions.
There may also be cases when nearby electrical appliances adversely affect the printer,
causing data errors or malfunction.
Avoid using the printer near a radio or TV set or supplying it from the same outlet as these
appliances.
Avoid using the printer interconnected with a cable or cord that has no protection against
noise.
Avoid using the printer with a device that is a strong source of noise.
Use the printer with its grounding post connected to an appropriate grounding facility.
Before connecting or disconnecting the grounding lead to or from the printer, always unplug it
from supply outlet.
If leakage occurs electric shock may result.
Do not connect the grounding post onto any of the following facilities:
Utility gas piping. (A gas explosion could result.)
Telephone line ground
Lighting rod
Utility water pipes (Plastic water pipes should not be used for grounding.)
To prevent possible malfunction or failure, observe the following.
Avoid operating the printer without paper properly loaded.
Avoid the use of paper not complying with specifications.
Avoid using torn pieces of paper or spliced with plastic adhesive tapes.
Avoid forcibly pulling already loaded paper by hand.
Avoid wedging the paper in by the paper cover or others.
Avoid using a sharp pointed device to operate panel keys.
Be sure to firmly insert the cable plug into its mating socket.
A cross connection may damage the printer’s internal electronics or the host system’s
hardware.
To prevent injury and further printer failure, observe the following:
Do not touch the printing surface of the thermal head. The thermal head is at a dangerously
high temperature immediately after printing
Do not touch any of moving parts (e.g., paper cutter, gears, active electrical parts) while the
printer is working.
In case of trouble, do not attempt to repair the printer. Refer to you qualified service personnel.
Caution:
When cleaning the printer, use a soft, dry cloth for cleaning the front surface of the printer door.
For severe stains, use a soft cloth slightly dampened with water. Never use organic cleaning solvent
such as alcohol, paint thinner, trichloroethylene, benzene, or ketone. Never use a chemically
processed cleaning cloth. To remove paper chips, use a soft brush.

5.3 Tech Tip
When replacing the DW-10 or DW-12 printer on 4/Vista™ dispensers, the printer door must be
fully opened before securing the printer bracket to the bezel mounting screws. This will allow
the printer to rise up slightly and the top screws should grip the bracket properly. Note that if
the 4/Vista fixed mount printer is allowed to drop down too low on the top screws, paper
loading will not be possible because the printer door will not fully open.
