Engineer Training Data Path TJ8300 / TJ8500 Confidential 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.

Engineer Training Data Path TJ8300 / TJ8500 Confidential 5 MTFX-QLM Box

Engineer Training Data Path TJ8300 / TJ8500 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.

Engineer Training Data Path TJ8300 / TJ8500 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).
