Overview
This explains the overview of troubleshooting process on how to service the dripping prevention system.
ITM suction blower
●
Amatek NautilAir blower CA345-42161 (spare part CU316-04281 BLOWER-NAUTILAIR 8.9 IN WITH
TACHOMETER mfg P/N 150241-57-0).
●
The blower should operate whenever the Press is connected to power (even in Off mode or
Emergency Stop).
●
For HP Indigo WS6000 Series Digital Presses with
software v.8.9.1.I20
and above: in Printing mode,
blower voltage should be 7.07 V.
In the SysTab,
miscEngineTopic > feedSuctionHighSpeedLevel
=
730
.
At this value, the blower is at the optimal flow rate for the dripping reduction kit ( ≈ 240 L/sec).
●
For HP Indigo WS6000 Series Digital Presses with
software v.8.9.1 I20 I-fix1
and above, or for HP
Indigo W7200 Series Digital Presses with
software v.8.11
and above: in all modes except for Printing
mode, Get Ready, Cold Start, and Pause, the blower control voltage is set to
5.57 V
.
In the SysTab,
miscEngineTopic > feedSuctionLowSpeedLevel
=
580
.
At this value, the flow rate is same as for the old model blower ( ≈180 L/sec).
DC fan ( catch tray fan )
●
For
software v.8.9.1 I20 I-fix1
: the DC fan (IO_CS_CATCH_TRAY_FAN) operates only during Printing
mode (not including Get Ready, Cold Start, or Pause mode).
