PHB-CF3 – Toshiba CF3 Printhead Driver Board


PHB-CF3 is AEWA printhead driver board for Toshiba CF3 printhead. It connects to AEWA Print Manager Board (APMB) via optical fiber cable which makes the data transfer immune to electromagnetic interference. It can also be run in electrically noisy environments without concern as electrical noise will not affect fiber.


  • Supports Toshiba CF3 printhead (600 dpi, 1278 nozzles).
  • Can print also 2 colors with one printhead.
  • Optical fiber interface for long distances, 600 Mbits/sec.
  • Generates accurate printhead driving voltages which are factory programmed. Printhead voltages can be further adjusted for special ink types.
  • Printhead voltage control with respect to temperature.
  • Correct voltage sequencing during power ON and power OFF.
  • Gray scale printing, up to 8 levels.
  • Printing waveform stored in the EEPROM.
  • Tickling pulse generation logic to keep nozzles always active.
  • Printhead temperature monitor, over temperature protection.
  • Firmware update over optical interface.
  • Single 24V input voltage with reverse polarity, over current and surge current protection.
  • SHA Encryption for firmware copy protection.
  • Small footprint, 75mm x 100mm.
  • Easy software integration with APMB SDK which supports native C++ and .NET programming languages such as C# or Visual Basic.
  • Compatible with APRINT RIP and Print software.
