~ IMAGER CLEANING PROCEDURES ~
To increase the reliability and useful life of your imager, OYO has designed the following cleaning
procedures. The regular use of these procedures is required to ensure compliance with OYO’s warranty
protection for both the imager and the print head. The use of any other procedure may void the warranties
offered by OYO.
The thermal print head, rollers, media conditioner, and interior of the unit should be cleaned after use of
every roll of media, or sooner if required.
Print head Cleaning Instructions:
• Wear only latex (non-powder) disposable gloves (part # 540V1106001). When handling and
cleaning the print head, the use of latex gloves is required to keep salts and oils present on the
operator’s hands from depositing onto the print head surface.
• Use only 98% isopropyl alcohol cleaning wipes (part # 160V1106001). A mixture containing a
greater percentage of water may act as a carrier for salts (ions) which may lead to print head
corrosion.
• With the cleaning wipe, rub the entire length of the print head.
• After cleaning, dispose of all cleaning material. Do not reuse.
• Make sure surface of print head is completely dry before closing unit.
Imager Cleaning Instructions:
• In order to remove any contaminants and/or residue from the rubber platen roller and metal idler
roller, these components of the imager unit should also be cleaned with 98% isopropyl alcohol
cleaning wipes. All surfaces should be completely dry before closing the unit.
• The inside of the imager unit, including the media conditioner, should be vacuumed thoroughly
before loading the next roll of media.
• The back and side filters should be checked and vacuumed monthly (or replaced, if necessary) to
ensure adequate airflow across the thermal print head.
Other Precautions:
• The print head should never come into direct contact with the platen roller (black drive roller).
Either a piece of Mylar or film should be placed between the print head and the roller if no media is
loaded in the imager.
• Do not place media or media hubs directly on the floor or on any other unclean surface. Doing so
may cause contaminants to be picked up and introduced into the imager and cause print head
damage.
• Avoid using the first and last wraps of media on the roll. This portion of the media may contain
contaminants due to handling. The manufacturer provides extra media on each roll to compensate
for this procedure.
• The front panel of the imager should be opened every three months and shavings from the cutter
removed with a vacuum.
