Caution - Electrostatic Sensitive Devices
The
printed circuit boards contain static sensitive devices. A suitably grounded, antistatic wrist strap
must be worn when working on or handling printed circuit boards.
Caution - False Readings
To avoid the risk of false readings, the pump zero offset should only be calibrated when there is no ink
in the system and the pump is off.
Caution - Print Quality
To ensure high print quality, ink viscosity must be checked and must be correct prior to attempting
modulation calibration.
Caution – Incorrect Measurement
If the temperature compensation factor is not used, the end result could be incorrect
by as much as 40%.
Caution - Equipment Damage
Never attempt to bend the gutter. Its position is fixed.
Caution - Damage to Charge Electrode
Take care not to deform the charge electrode slot when rotating the charge electrode.
Caution - Charge Cable
Ensure that the charge cable is not pulled out of its position in the rear face of the
deflector block assembly.
Caution - Equipment Damage
Never attempt to bend the gutter. It is in a fixed position.
Caution - Equipment Damage
The I/O Board LEDS connector must not be used to drive anything other than LEDs as specified
otherwise damage may occur.
Caution - Excessive Use of Top-Up or Solvent
As solvent is used during the stop cycle, repeatedly stopping and starting the printer can lead to
excessive use of top-up or solvent and may lead to a Mixer Tank High error.
Caution - Quick Stop
After a Quick Stop machine should not be left in this state for any length of time as drying ink may
make restarting difficult
