  4. Data Path Components Inside the Computer • ILP2000 Board – Data process board – Reads the image data, which is loaded into the memory by DMA method (Direct Memory Access) without using CPU time, in order to accelerate the process. • TTLC Board – RS422 Transmitter – Receives the data signals from the ILP2000 board and transmits them to the QLM box. • Advantech I/O – Responsible for Communication between the computer’s PCI bus and the MTFM boards (ISA) inside the QLM Box. Confidential

  5. MTFX-QLM Box Confidential

  6. MTFX-QLM Box (Cont.) • The purpose of the QLM box is to serve as ISA to PCI adaptor, since ISA slots are no longer manufactured. • Consists of two MTFM ISA boards and a QLM board. • 32-bit Printing data is “transferred” from the ILP2000 board (via the TTLC Board) to the QLM board. The QLM board interpolates the printing data to 96-bit and sends it to the two MTFM boards, 16-bit per each color. Confidential

  7. MTFX-QLM Box (Cont.) • The “SEND TABLES” command (timer parameters-printing mode and resolution), is sent to the QLM box, which is supplied from Advantech I/O PCI (located inside the computer). See data path functional description. • One board is dedicated for four colors (C, M, Y, K) and the second board for the other two (CL, ML). Confidential

  13. TPFM Rack (Cont.) • Every TPFM board functions as one TIMER and four PFM’s of PJ. The reason is that the data channel is twice as much as in the PJ machines due to the difference between the IJ heads(96 nozzles in the TJ8300 compared to 48 in the PJ). • All 3 boards are similar and can be swapped easily for troubleshooting. • The following voltages are supplied to the 2U rack: • 12V DC for TPFM boards • 12V DC for I.J drivers • 48V DC for I.J drivers Confidential

Confidential

  16. TPFM Rack (Cont.) • Indication Lights (Cont.) • CONFDONE • Should be on after “send tables”. • FUNC • Blinking after send tables (before it is off). • JOG • On when the drum is jogging. • START • On as soon as the machine starts to receive data. Confidential
