The Print Data is transferred from the software to the RIP through the PCI Bus.

1. The print data is transferred from the PLX PCI Bridge to the Memory Chips.

2. All the Print Data is then processed in the Altera Chips:(Master → Slave) and transferred through the SCSI 68 pin to be distributed to all four channels.

3. All the Print Support Data and Commands are processed and directed through the Altera Slave, except for the PEG data and the Encoder Signals.

Pumps Board

The Pumps Board performs the following tasks:

1. Splits the 24 VDC to all operating Ink Cabinet channels.

2. Controls the ON\OFF commands to each of the solenoids mounted on the Main Ink Cabinet.

3. Transfers the Ink Sensor reading from the Main Tanks to the RIP2CCB.

4. Provides LED indication of 24 V on each channel (red) and Solenoid Valve ON (green).

Operation

1. The Board receives a 5V supply from the RIP2CCB and 24VDC from the power supply located under the Board.

2. The 5V is used for the operation of the Solid State Relays.

3. The 24V is supplied to the Valves and the Pumps.

4. The control of the Ink Valves is performed by a set of Solid State Relays.

Sensor Control Board

The Sensor Control Board\Overflow Board is a very simple connection panel, there is no IC in this board, only Connectors, Resistors and LEDS.

The Board is basically divided into 4 identical partitions, each partition belongs to a specific Color and CCB.

Each partition is divided in 2, one that belongs to the Left Tank and the other to the right tank.

On this board there is also a White 4 pin Molex Connector that is connected to the Jet 132 JP3.

Through this connector, the pumps are activated or deactivated if there is an Overflow.

LED CONFIGURATION

There are 16 Green LEDs on the Board that are connected on a serial configuration from left to right.

If there is an Overflow in a specific partition of a specific tank, the LED is turned Off, starting from the LED that has the overflow to all the LEDs to the right of this one.

The first LED that’s OFF from Left to Right indicates the Tank and Partition with the overflow.

There are 4 LEDs for each Color, 2 for each tank and 1 for each partition.
