  6. RIP3 Board (Cont.) • The Print Data is transferred from the software to the RIP through the PCI Bus. • The print data is transferred from the PLX PCI Bridge to the Memory Chips • 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 • All the Print Support Data and Commands are processed and directed through the Altera Slave, except for the PEG data and the Encoder Signals. Confidential

  8. RIP2CCB Board Confidential

  9. RIP2CCB Board (Cont.) RIP2CCB is a PCB Board, connecting bridge between all the electronic components of the XL1500. Confidential

  10. CCB 2 Board • Overview: • The CCB board is a PCB board. • There are 4 identical CCB boards on the machine, all are located on theHead Carriage. • Functions: • Receives printing data from the Rip to CCB. • Translates and transfers the data onto to the printing heads. • Provides feedback of ink level in the secondary tanks. • Controls ink filling in the secondary tanks. • Controls the purge process. Confidential

  12. CCB 2 Board - LEDS

  13. CCB 2 Board – Current revision All LEDS are in the same position except the 35v LEDS, moved to those positions. Confidential

  14. CCB 2 Board (Cont.) Confidential

  15. Pumps Board – Old Revision • The Pumps Board performs the following tasks: • Splits the 24 VDC to all operating Ink Cabinet channels. • Controls the ON\OFF commands to each of the solenoids mounted on the Main Ink Cabinet. • Transfers the Ink Sensor reading from the Main Tanks to the RIP2CCB. • Provides LED indication of 24 V on each channel (red) and Solenoid Valve ON (green). Confidential

  16. Pumps Board • Operation • The Board receives a 5V supply from the RIP2CCB and 24VDC from the power supply located under the Board. • The 5V is used for the operation of the Solid State Relays. • The 24V is supplied to the Valves and the Pumps. • The control of the Ink Valves is performed by a set of Solid State Relays. Confidential

  17. Pumps Board (Cont.) Confidential

  18. Pump Board – New Revision Confidential

  19. Pump Board – New Revision (Cont.) • The Pumps Board performs the following tasks: • Splits the 24 VAC into all operating Ink Cabinet channels. • Controls the ON\OFF commands to each of the piston pumps mounted on the Main Ink Cabinet. • Transfers the Ink Sensor reading from the Main Tanks to the RIP2CCB. • Provides LED indication of 24 V on each channel (red) and Solenoid Valve ON (green). Confidential

  20. Pump Board – New Revision (Cont.) • Operation • The Board receives a 5V supply from the RIP2CCB and 24VAC from the 24v transformer, which is located under the Board. • The 5V is used for the operation of the Solid State Relays. • The 24V is supplied to the piston Pumps. • The control of the Ink piston pumps is performed by a set of Solid State Relays. Confidential

  21. Pumps Board (Cont.) Confidential

  22. Motion Adapter • The Motion Adapter is a bridge that transmits data from the Motion System Hardware to the software • In the present configuration, the Motion Adapter functions as a bridges among the: • X DRIVER • CONTROLLER • RIP to CCB BOARD • Control of the Heating System Confidential

  23. Motion Adapter (Cont.) • Work Concept • The core of the Motion Adapter Board is BLOCK 1, which contains a set of Line Drivers and an Opto-coupler. • A and B Differential Signals are transferred from the Motor Encoder through the Board to the Rip2CCB. • PEG data is transferred from the Motion Controller through the Board to the Rip2CCB. • PAUSE command and OPTIC SENSOR data is transferred from the RIP2CCB to the Motion Controller. Confidential

  24. Motion Adapter (Cont.) Confidential

  25. Motion Adapter (Cont.) Confidential

  26. 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 Overflow. Confidential

  29. Over Flow Board Wiring – Premium Left secondary tank Right secondary tank Confidential

  30. Sensor Control Board (Cont.) • LED CONFIGURATION • There are 16 Green LEDs on the Board, and these 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 will be turned Off from the LED that has the overflow as well as all the LEDs to the right from this one. • This means that 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. Confidential
