310-/240-bit shift register, Gate *1, Index *2

Part 4: Technical Reference

BJC-7100

3)Description of block diagram Block enable decoder *1

Generates BLOCK1 to 6 according to BE0 to 2 from the logic board.

The output sequence of BLOCK1 to 6 is inverted according to whether INV is High or Low.

310-/240-bit shift register

Converts IDATA *1 from the logic board into parallel print data for output.

310-/240-bit latch

Latches and outputs the parallel print data using the LTCLK timing.

AND gate *1

Outputs the part of the parallel print data specified by BLOCK1 to 6, EVENE, and ODDE.

310-/240-bit transistor array *1

Turns on the heaters according to the print data from the AND gate.

The heaters, which are pulled up to VH, are turned ON by setting the heater connection Low.

Heaters 1 to 310, or 1 to 240

The heater temperature rises when turned on to pre-heat and main-heats the nozzles. The heaters are aligned with the nozzle array against the nozzles in the head holder.

Rank resistance

Differences in the heater characteristics of the various BJ heads are ranked and marked using their resistance, which is detected by the printer. The resistance is read by the A/D board of the MPU as a voltage and converted to digital format to detect the rank, allowing the BJ print heads to be controlled for optimum print quality.

Sub-heater

This heater adjusts the temperature of the heater board to stabilize the ejection of inks. The printer drives the sub-heater according to the temperatures detected by the head temperature sensor and printer temperature sensor, which is mounted on the carriage board, and the print mode, etc.

Head temperature sensor

The head temperature sensor outputs the temperature of the heater board to the printer. The voltage output by the head temperature sensor is read by the A/D board of the MPU as a voltage and converted to digital format to detect the temperature. The print quality is controlled and the head prevented from overheating on the basis of the detected temperature.

Electrode *2

The ink-out detection pulse is output to the ink room on the head holder to detect ink-outs in the ink-path.

Index *2

The type of BJ cartridge mounted in the printer is output to the printer.

*1: The connection and order of IDATA differs according to the type of BJ cartridge.

*2: Some of the electrodes of the color and photo heads are connected to contacts that are shared with the index.
