Handling precautions
The precautions below are recommended to avoid damage to the Printer and its components.
Power supply
1. Install the Printer near the socket. To pull out the power plug in an emergency, the power socket must
be reached easily.
2. Do not share the power supply with the noise generating devices such as a motor.
3. Use the power supply voltage specied on the nameplate.
4. Monthly turn o the Printer and check the following:
- The power plug is inserted into the socket securely.
- No dust is accumulated between the plug terminals and socket. When dust is found, clean the area
with a dry cloth.
Printer
1. Do not place anything on the top of the printer.
Do not rest your elbows on the Printer. Especially
be careful not to block the printer's exhaust outlet
shown by the gure below.
2. Do not apply shock or stress to the Printer.
3. During the print operation, do not open the front cover, nor set the pressure control knob to “Open.”
Otherwise the printer operation is terminated.
4. Do not clean the cover’s surface with benzene or paint thinner. This may damage the Printer’s paint. Clean
the cover’s smear with a soft cloth. If the cover is considerably smeared, wipe it o with a cloth moistened
with water-diluted neutral detergent. If it is not cleaned, the smear may aect the Printer’s surface painting.
5. Always use the OKI Data Infotech-specied attachments and options. The other products may degrade
the image quality, damage the Printer, and disable the maintenance.
6. Never touch the print head nozzles. They can be easily damaged or clogged.
Regular inspection and maintenance
Due to solvent ink characteristics, inspection and maintenance need to be performed periodically. (For
details on maintenance, see the Maintenance section starting on
page 66
.)
1. Perform the start maintenance every day before starting using the Printer.
2. Pay particularly attention to the items below.
Regularly replenish the wiper cleaning liquid and spittoon absorber liquid.
Once per month, clean the print heads using the head cleaning set (IP7-166).
Print heads are highly-precise parts. Do not wipe the nozzle surface directly.
3. If you leave the Printer o for more than 2 weeks, perform the service cleaning.
4. If, after the service cleaning, you leave the Printer for a long time and again you start the print operation
with the Printer, be sure to perform the head wash and charge the ink system.
Consumables
1. OKI Data Infotech ink packs should be installed before the “Install By” date printed on the pack. The
other ink may damage the Printer, and the Printer repair fee is borne by you.
2. In order to guarantee ink quality, ink expiration dates have been determined. Always use consumables
before their expiration date, otherwise they may cause a malfunction.
3. Put used ink packs into a plastic bag and dispose of them as industrial waste. Observe local regulations
for disposal of consumables.
4. Unpack the OKI Data Infotech ink pack package only when they are installed. Do not store OKI Data
Infotech ink packs in direct sunlight. Store the OKI Data Infotech ink packs in a cool, dry place. This
prevents deterioration of the ink during storage.
5. Do not disassemble the ink packs and subcartridges. They are intended for single use only.
6. Do not drop the ink packs and subcartridges. Avoid shock to them. The drop or shock may cause an ink
leakage.

Media
¢Supported media
The Printer supports the solvent inkjet media of the types below. Note that the print condition may change
depending on the environmental conditions and the media production batch. So you are recommended to test
the print with the media beforehand.
For details, contact your service representative.
Vinyl
Banner
Mesh banner
Backlit banner (FF)
Solvent printing coated paper
¢Precautions on storing media
¯At storing media, packed or unpacked, avoid direct sunlight and water stained. To avoid dust put the
media into a box or a bag, and keep it in a cool and dark place.
¯Avoid a rapid temperature change to prevent a dew condensation.
¯Do not store media upright. The media stored upright may be deformed to be telescopic due to its
weight, or may deform its edge.
¯Do not pile up the roll media.
¯Make sure the media rolls are secured when stored. They are heavy and may cause injury if they roll or fall.
¢Precautions on disposing of media
¯Dispose of media or printout in compliance with all local, state, and federal regulations.
¢Precautions on using media
¯Do not subject the unpacked media to the temperature and humidity change. Before loading the
media on the Printer, leave the media in the operating environment for three hours or more. Note that
the ambient humidity change may aect the media by turning on or o the air conditioner.
¯The media may be curled in a lower temperature, and wrinkled in a higher temperature. Keep the
temperature around 23°C and the humidity around 50% when you use the media.
¯Do not use a part of media when the part is scratched, wrinkled, turned, or with obstructions. Never use
the damaged media, as the right and left edges of the media are especially critical to feed media on the
Printer. Besides, do not drop the media and avoid water stained, which may degrade the image quality,
and cause the Printer’s malfunction.
¯Do not touch the printed image but the margin part. The image quality may be degraded by your
insensible sebum and sweat.
¯When the media is wound telescopically at loading on the Printer, correct the slippage before using.
¢Precautions on handling printouts
¯Do not touch the printed surface of the media before the ink dries, or especially 24 hours after printed.
Handle the printout by securing the margins.
¯Do not scratch the printout to avoid the color lost or transferred. To avoid the printout’s color
transferred, do not put the printed media on the other printed media with their printed surface facing
each other.
¯Do not put the printed media on the printout from copier or laser printer. The printouts’ ink or toner
may stick the two printouts.
¯Note that an ink on the printed surface may come o if the surface is rubbed hard or scratched.
¯The printed image may bleed or be lost if the water-stained printout is scratched hard or left.

11
¢Other precautions
¯Media loses its color and quality with age. Check the media condition and select the media with better
condition.
¯Cut the media carefully, as its paper dust may cause bubble surface at laminated.
¯When adhesive-backed media is applied, some adhesive agent may be left on the platen, which
may cause a media jam. So clean the agent completely with a soft cloth moistened with the neutral
detergent.
¢Available area on media
The available area on media in scanning direction depends on media width, media edge guards application,
and stripe bar presence. With the media edge guards and stripe bar applied, your available area is decreased by
34.9mm in right and 10.0mm in left. The available are is decreased more when the optional product below is
