XF
eXtendo® Thermal Printer Family

2.2 General Information

Hengstler GmbH accepts no liability for the safe operation of the eXtendo® XF thermal printer family
unless Hengstler original products are used exclusively and the following instructions and
recommendations are heeded.

Connect the printer closely to the power supply to minimize ground level rise during high-current-
draw printing. Connect the host signal GND closely to the printer GND (star topology).
Note: Different GND levels between host and printer can lead to high compensating currents through
the data cable which can impact the data transmission or even damage printer or host electronics. If
you cannot provide sufficient grounding, consider using appropriate data port isolators.

The DC power connector must not be plugged in or disconnected under load in order to avoid
damage to the electrical components and the thermal printhead.

Unapproved types of thermal paper may drastically reduce the life of the print head or cutter and
may cause the guarantee to expire. For pre-printed thermal paper make sure that only appropriate
inks are used. Details can be found in the Hengstler Paper Specifications as listed in → Chapter 1.1.

If unauthorized persons perform any repairs or modifications to the printer mechanism and the
controller, HENGSTLER will not accept any liability and the guarantee shall be void.

Avoid strong vibration, shock and impact since they may damage or destroy sensitive electronic and
mechanical components. Do not touch the surface of the printer control board in order to prevent
static electricity from damaging sensitive components.

This thermal printer must not be used near to high-frequency apparatus or strong magnetic fields in
order to prevent undefined magnetic disturbance.

Do not make any attempts to service this printer (e.g., change paper) while the printer is printing.

Installing or uninstalling the printer must only be done while using adequate ESD protection.

Make sure the printhead properly locks and both ends of the locking shaft are snapped into their final
positions (→ chapter 3.2 detail 3a).
