TJ8300 / TJ8500 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.

Data Path
TJ8300 / TJ8500MTFX-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.

TJ8300 / TJ8500MTFX-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).

TJ8300 / TJ8500TPFM Rack

First TPFM board for Cyan and Yellow colors
Second TPFM board for Magenta and Black colors
Third TPFM board for Light Cyan and Light Magenta
All boards are easy to access and service

Engineer Training
Data Path
TJ8300 / TJ8500TPFM 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

Indication Lights
Over run (Red LED)
Indicates an error that appears when the TPFM board is asking for data but the QLM-MTFX box is not sending any,or any other problem in the data flow.
The over run should be:
• Blinking only before initialization (“send tables”).
• Off after initialization, which indicates OK status.
Live (Green LED)
Normally blinking, which Indicates FM initialization(after “send tables”).

• LF clock
• Frame
2. Receives 1-bit Tiff Raster data from QLM-MTFX box.

TJ8300 / TJ8500IJ Drivers Diagnostics
Each driver is able to sample, measure, and transmit to the host the information regarding inkjet pulse shapes.
The host can receive this information from each specific driver (each color separately on each driver) and present it on the computer’s monitor as a graph (in the real time software).
The transmitting protocol that the driver supports is serial RS232 full duplex.
Each driver has a different address, which is set according to row and column of placement.

DTW_QLMT Board -The QLMT contains two things, QLM & Timer; the QLM use as a Buffer of information and the timer synchronizes the information according to the drum movement (encoder reading and home position).
DTW_ADD_ON Boards -There are three ADD ON boards; every ADD ON controls two colors and transmits the plot Data towards the bridge with correct timing.
