3) After the alignment above, reverse the transport direction

and check the FWD alignment again. If it is deviated, perform

alignment again.

CAUTION : For continued safety, replace safety critical

components only with manufacturer's recommended parts

(refer to parts list).

Indicates safety critical components. To reduce the risk

of electric shock, leakage-current or resistance

measurements shall be carried out (exposed parts are

acceptably insulated from the supply circuit) before the

appliance is returned to the customer.

• DC voltages are as measured with a high impedance

voltmeter. Values may vary slightly due to variations

between individual instruments or/and units.

CAUTION : For continued safety, replace safety critical components only with manufacturer's

recommended parts (refer to parts list).

Indicates safety critical components. To reduce the risk of electric shock, leakage-current or

resistance measurements shall be carried out (exposed parts are acceptably insulated from the

supply circuit) before the appliance is returned to the customer.

• DC voltages are as measured with a high impedance voltmeter. Values may vary slightly due

to variations between individual instruments or/and units.
