3 Clean the printhead

WARNING:  HAZARDOUS INKS AND SOLVENTS. SAFETY GLASSES AND 
SOLVENT-RESISTANT PROTECTIVE GLOVES MUST BE WORN THROUGHOUT THE 
FOLLOWING PROCEDURE. IGNORING THIS SAFETY WARNING COULD RESULT IN SEVERE 
EYE IRRITATION AND TEMPORARY (REVERSIBLE) EYE DAMAGE, AND NON-ALLERGIC 
CONTACT DERMATITIS.

WARNING:  FLAMMABLE LIQUIDS. THE INKS AND SOLVENTS USED WITH THIS PRINTER ARE 
HIGHLY FLAMMABLE.
KEEP INKS AND SOLVENTS AWAY FROM SOURCES OF IGNITION. DO NOT SMOKE OR USE 
OPEN FLAMES NEAR THE PRINTER, OR INK AND SOLVENT STORAGE CONTAINERS. USE 
INKS AND SOLVENTS, AND OPERATE THE PRINTER, IN AN AREA WITH GOOD VENTILATION.
THERE IS A RISK OF FIRE OR EXPLOSION IF THIS SAFETY WARNING IS IGNORED.

CAUTION:  Do not clean the printhead by immersing it in solvent, or by using an ultrasonic 
bath. This will cause damage to the printhead and will void your warranty.

CAUTION:  Do not dry the printhead with a cloth. This may deposit fibres that could block the 
printhead nozzle.

CAUTION:  Only Linx foam swabs (FA69034) and Linx Food Grade solvent 6600 must be used 
to clean the printhead. Other materials or fluid can cause damage to the printer and invalidate 
its Food Grade status.

3.1 About the procedure

NOTE: To clean the MidiEC printhead you must use a special procedure. The cleaning 

procedure described is for the Linx 7900 Food Grade printer only. The cleaning 
procedure for the standard 7900 printer is described in the 

Linx 5900 & 7900 Quick 

Start Guide

.

For reliable printer operation, you must make sure that the MidiEC printhead is free of ink 
deposits or moisture. Clean the printhead after every work shift, or after an incorrect 
shutdown (for example, a power failure when the jet is running).
