Powering off the NetVista Kiosk
Use the following power-off sequence to ensure that the NetVista Kiosk components
are powered-off.
1. Switch off the power to the 4835 system by pressing the power button with a
paper clip. The power button is located on the front bottom of the 4835 display.
The display indication lights Awill not be lit.
2. Unplug the power cord B that runs from the NetVista Kiosk enclosure to the
external ac power source.
3. Unlock the enclosure and slide the front of the enclosure forward. See ″Opening
the enclosure″on page 9 of the Hardware Service Manual.
4. Turn off the power switch C on the optional UPS (if installed).
5. Switch off the power-distribution strip D.
6. Make sure that the scanner is powered off by holding a white sheet of paper at
location E. No red light pattern will be displayed.

Installing the paper roll
Attention:
1. Establish personal grounding before touching this device. For more information,
see ″Electrostatic discharge (ESD)″on page 158 of the Hardware Service
Manual.
2. Keep your fingers clear of the paper cutter while pressing the paper advance
button or when powering on.
3. Install the paper roll after you verify that your system is powered-on. See
“Powering off the NetVista Kiosk”on page 4 for more information.
4. Do not use grade of paper other than that specified for this product. Using an
inferior grade paper can affect the print quality and the life of the print head and
printer mechanism. The NetVista Kiosk supports the 58-mm, the 80-mm, or the
112-mm thermal printer.
To install the paper roll, do the following:
1. Set the winding direction of the paper roll so that the temperature-sensitive side
faces up.
2. Align the core of the paper roll with the movable shaft and insert the paper roll
all the way into the shaft. After the insertion make sure that:
vthe extremity of the movable shaft is visible
vthe paper roll is not misaligned with its core
vthe paper roll rotates smoothly

The NetVista Kiosk-DBCS Model 5

3. Referring to the paper insertion indication label, pass the paper roll over the
tension roller so that the printing side and the tension side come into contact.
4. Insert the paper roll into the slit of the side guide R. The paper is automatically
fed into the slit for 400 dot lines (approximately 50 mm) and the printer enters
the Offline state.

5. Press the Select button to feed out the paper and to place the printer in the
online state.

Note: At autoloading, the paper is not automatically fed into the printer under the
following conditions:
1. When the platen is open. Be sure to close the platen.
2. When the upper guide on the presenter is open. Be sure to close the
upper guide.
3. When paper is left in the presenter. Press the Feed button to remove the
paper. Or, loosen the thumbscrew, open the cover, and remove the
paper.
4. When a paper-out error is disabled by a command. Reset the paper.
Attention: Observe the following points at autoloading:
1. Cut the edge of the paper so that its angle to the feed direction is between 60°
and 90°as shown:
(Front of paper)
90 60
(Front of paper)
2. When inserting paper, make sure that the platen and the upper guide on the
presenter are closed (is a presenter is attached).
3. If the paper is skewed, set the paper straight with the platen open.
4. If the printer unit is left with the platen closed, the thermal print head may stick
to the platen, preventing paper to be inserted. Then, open the platen before
inserting the paper.

Printer test printout
You can take a test printout which shows the function settings and the special
characters you can use. To take a printout, press and hold the Feed button while
powering on the printer.

A test printout like the one shown below is printed.
The printer returns to the Online state after the test printout is printed.
Note: Do not turn off the printer when you have pressed both the Feed and the
Select buttons. Doing so may damage the hardware.

Troubleshooting
This section describes how to resolve a DBCS printer problem.
To solve a problem, do as follows:
1. Go to ″Preliminary checklist″below and do the steps. If you cannot solve the
problem there, then...
2. Go to ″Resolving problems through LED″below and try to solve the problem
there. If you cannot solve the problem, then...
3. Go to “Diagnostics”on page 12 and try to solve the problem there.
Preliminary checklist
When you power on the NetVista Kiosk, it performs a Power-On Self-Test (POST).
The system indicates a successful POST with a single beep. The scanner may
beep four times during a power-on. If the system displays an error message or
beeps more than once, see either ″POST error codes″on page 38 or ″POST beep
codes″on page 40 of the Hardware Service Manual.
Otherwise, perform the following steps to diagnose the problem.
1. Verify that the power strip, in the Kiosk enclosure, is plugged in the UPS and is
powered-on.
2. Make sure that the unit is connected to an ac power source and that all the
power lights are on.
3. Make sure that all cables and I/O devices are connected correctly and securely.
4. Make sure that the contrast and brightness controls are properly set. Use a pin
to adjust these controls located at the bottom right of the display.
5. Record any error messages or symptoms for troubleshooting.
If you do not observe a specific error indication, continue with the problem solving
at “Resolving problems through LED”.
Notes:
1. You can use the Service Diskette for internal-option-related or
peripheral-device-related problems. See ″Service diskette, device drivers, and
diagnostic information″on page x of the Installation and Operation Guide.
2. Some devices that attach to the system have test instructions. Refer to those
instructions when testing those devices.
3. If you are using a specific application, you may receive application-unique error
messages. Refer to the software manual shipped with the software.
