Adjusting the Power Supply Unit Replacing and Adjusting the Print Heads
9-10 Sprinter User's Manual
Figure 9-9: Power Supply Voltage Screw
You adjust the voltage by turning the VOLTAGE SCREW (Figure 9-10).
When adjusting the voltage on a set of eight P
OWER SUPPLY UNITS, you must
carry out the procedure on each unit separately. You must firstly remove
the jumper between contact RC and RCG, then carry out the adjustment
and relocate the jumper.
These current changes can influence the heat and the temperature of the
heads and consequently, changes in colors.
Whenever a head is changed, the power supply voltage of the
corresponding P
OWER SUPPLY UNIT(S) must be calculated again and changed
if necessary according to the formula below.
Vps = 1.8V + 0.444 *
Rhead
*Rhead is the resistance on the head (2500 to 2800Ω).
Vps: the power supply should be calibrated to his voltage.
