2.3- CLEANING PROCEDURE AND PRECAUTIONS
In order to clean the thermal print head, proceed as indicated by the following steps:
1- Unplug the power supply cable and open the front door.
2- Remove the paper roll and the thermal print head will be accessible from downwards.
3- Soak a cotton sponge in alcohol (ethanol, methanol or IPA), and rub it gently along the
thermal head in order to remove the possible accumulation of paper particles.
4- Wait for alcohol to evaporate before inserting the paper roll and closing the cover.
FENIX recommends cleaning the thermal print head periodically (every 2 or 3 months) in order
to keep an optimal print quality.
NOTES:
 The print head may be hot after printing. Make sure it has thoroughly cooled down
before proceeding to clean it.
 Never touch the thermal elements of the print head with your hands.
 Never use metallic or piercing elements to clean the print head, as they could scratch it.
2.4- RECOMMENDATIONS
• The plug has to be located near the printer and has to be easily obtainable.
• Before connecting any communication data cable, check the printer is working properly by
executing the self-test.
• Set the EPC1800 in a place where the connection cables do not suffer stretching or cross with
each other.
• IMPORTANT!!! Since the printer demands high current peaks during operation it is advisable to
make the power supply cables the shortest possible.
