10. Pressure Window Check
The pressure window is the range of usable ink pressure that the printer
can be set to, before print quality becomes unacceptable.
The printer should operate at approximately 2900mbar (4000mbar for
Pinpoint) with a message that uses all available lines.
(1) Take a print sample by sweeping a piece of card under the
printhead whilst triggering the product detector (simulating a
product).
(2) Enter Service Mode and press the Ink System button. This will
display the target pressure.
(3) Note the original pressure and increment the pressure one step at
a time using the + key while checking the print quality. Continue
until print quality becomes unacceptable.
(4) Reduce the ink pressure to one increment below the original
pressure using the -- key, whilst checking print quality.
(5) Continue reducing the pressure, whilst checking print quality,
until the quality becomes unacceptable.
(6) The pressure should now be set to the midpoint of the pressure
window.
Note:
A typical window is +/--300mbar.
11. Modulation window check
Sequence the machine on. Enter Service Mode and press the Print Head
button. In this screen, press the
nr
buttons to go to the modulation Set
Point (make a note of the current value). Now use the +/
--
keys to
increase or decrease the modulation voltage. The voltage can be
adjusted in three levels: 0.1V, 1V and 10V steps. It is advisable to adjust
the voltage in 10V steps until the print quality deteriorates, the go back
10V and change in 1V steps to get an accurate print window. Check
print samples as normal to obtain the print window.
12. Pump Speed Check
Note:
This test should be carried out at an ambient temperature of 25
_
C
.
However, if the ambient room temperature is higher then the pump
speed will also be higher, and if the ambient temperature is lower
then the pump speed will be lower.
In Service Mode press the Ink System button, then press the Sequence
to Jet Run button. Once the jet has established itself in the gutter, make
a note of the pump speed, this should be approximately 2000rpm. If the
speed is 3500rpm or above it would be advisable to change the pump.
