CHAPTER 1
SETUP
The SKGG printer better known as the LOGO printer is
ideal for printing on paper rolls and if desired can also
be used to print labels when ordered with the optional
spindle.
This chapter explains how to set up your new
printer for optimum performance.
Unpacking the
printer The first step in setting up your printer is unpacking the
pieces. Be sure to save all the original packing
materials. They are specially designed to protect the
printer and will make repackaging easy if you ever need
to ship the printer.
Do you have
what you need? Having unpacked your printer. You should find the
following items ( shown in figure 1.1).
- SKGG ( Head 2.25") printer (SKGG1xxx is the
standard Logo, SKGG5xxx is the Logo Kanji).
- Serial cable
- Power transformer
- One paper roll (or roll of labels if ordered)
- User manual
- One spindle (if ordered)
Check carefully to see if everything is there. If not,
contact your dealer immediately.

Everything checked ? Let’s set up the printer.
Where to put
your printer Before setting up your printer, take a few moments to
consider where you plan to put it. There are a few
general guidelines you might consider.
- Ensure that there is enough room around the printer to
allow paper to flow out freely.
- Avoid placing the printer in areas where sudden,
severe changes in temperature and humidity occur.
- Avoid areas with direct sunlight, dust and grease.
- Pick a clean area.
- Select a steady source of electricity and check for
other appliances which may be using the same circuit.
Copiers, heaters, air conditioners and other motorised
equipment can cause power fluctuations which may
interfere with you printing.
- Use a surge protector.
Figure 1-1 . The printer is equipped with the following items: printer,
power transformer, serial cable, roll of labels or roll of paper, user
manual and spindle (option)

Connecting the Your printer and computer communicate through the
serial cable special serial cable that comes with your printer. The
cable has one connector at one end and that connects to
the printer and two connectors at the other end (one for
PC and one for Macintosh) one of which connects to
the serial port on the back of the computer. Use of the
serial port enables you to continue using your parallel
port for your regular document printer.
Follow the steps below while referring to Figure 1-4 to
make the proper connections:
1-Turn your computer and printer off.
2- Connect the printer end of the serial cable to the rear
of the printer (DB9 Female for a PC or mini-din for a
macintosh)
If you have a 9-pin serial port on computer, attach the
9-pin connector; if you have a 8-pin serial port, attach a
8-pin connector. Secure the connector with the two
screws. The connector you do not use can simply hang
loose. It does not need to be connected and will not
cause any damage to your computer or printer. See
Figure 1-4.

CHAPTER 3
MAINTENANCE AND
TROUBLE SHOOTING
The printer is designed to provide the user with a long and
trouble free service requiring very little maintenance. You'll
get the best possible performance from your printer if you
follow the instructions in Chapter 1 Setup and the
procedure described here. This appendix also covers
troubleshooting for printer errors.
Printer maintenance
Printer maintenance is quick and very simple. There is
no set procedure for maintenance; simply take the
appropriate measures as described below when
necessary.
The LOGO printhead can be easily cleaned using just a
few simple items. Use these items as often as needed to
keep your printer clean and in good working order.
You'll need these items:
•lint-free cloth
•isopropyl alcohol, diluted dishwashing detergent or
diluted (non-ammonia) glass cleaner
•small, soft brush, such as paint brush
use these items as they are called for in the maintenance
procedures described in this chapter.

Logo Kanji Printer User Manual Page 19/53 Ref : 3103188 FDE / A
Exterior
Maintenance
Cleaning the outside of your printer is as important as
cleaning the inside. Dusting the outside of the printer
occasionally will reduce the incidence of foreign matter
getting inside the printer. Follow these steps to perform
exterior maintenance of your printer:
1-Turn the printer off and disconnect the power cord.
2-Dirt, dust, ink and so on will more than likely be
attracted to the exterior of your printer. Use the lintfree
cloth to wipe the exterior of the printer. Remove dirt and
ink smudges with either isopropyl alcohol diluted
dishwashing detergent or diluted glass cleaner. Avoid
product containing ammonia for cleaning the printer of
plastic cover.
3-Take a minute to clean the work area around the
printer.
4-Reconnect the power cord and turn the printer on.
Interior
Maintenance
The printer's top cover will keep out most of the dust and
dirt which accumulates in operating areas. However, it is
still a good idea to periodically perform some basic
interior maintenance:
1- Turn the printer off and disconnect the power cord.
2- Open the top cover.
3- Use a small, soft paint brush to whisk paper dust or
other stray particles away from the inside of the printer.
Remove the paper or label roll to clean underneath, the
replace the roll.

Logo Kanji Printer User Manual Page 20/53 Ref : 3103188 FDE / A
4- Close the top cover.
5- Reconnect the power cord and turn the printer on.
Clearing paper and
label jams
If you experience jams with paper or labels,
take the following steps.
1- Open the printer's cover and use scissors to cut the
label or paper between the feed slot and the roll.
Figure A-1 clearing label jams
2- Press the form feed button to advance the paper or
labels through the printer. Reload the paper/labels as
described in CHAPTER 1 Set-up.
First, cut the
label/paper between
the feed slot and the
roll.
