2.3 - CLEANING PROCEDURE AND PRECAUTIONS
Paper dust, paper chips, and thermal chemicals attached to the heat elements of the print head
and the platen may reduce print quality. In order to clean the thermal print head, proceed as indicated by
the following steps:
1- Unplug the power supply cable and open the cutter unit.
2- Pull the paper lever in order to release the platen.
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 PTD55 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.
