Check the print head before every shift and clean as necessary.

down.
(2) Disconnect the power lead from the rear of the printer.

WARNING: Hazardous chemicals. Risk of personal injury.
Wear protective equipment such as gloves and glasses when near the
printer. Physical contact with printer ink or make-up can cause skin or eye
damage.
CAUTION: Risk of poor print performance
Switch off the printer before starting this procedure.
If the printer is running when this procedure is done, wash will enter the
gutter and may reduce the ink viscosity.
CAUTION: Switch off printer. Risk of EHT (Electrical High Tension) trip.
Switch off the printer before starting this procedure.
If the printer is on when this procedure is done, there is a risk of causing
an EHT trip by making an electrical short between the deflector plates.
