Mini Lab Help.com is now in the final stages of being handed over to new owners.

We would like to thank everyone for the support over many years and we wish the new owners all of the best to drive this web site for another 20 years. 

A sad time to say goodbye, but also a happy days as this site goes in a new direction.

Goodbye - Neil Taylor

  1. The fact is that the computer itself reacts to the connection and disconnection of colorimeter, but the LED does not turn on at all. What pin of connector P904 is responsible for connection to the colorimeter? Maybe the entire circuit board is broken? See attached file.
  2. Output check showed that the motors for paper pulling and pulling the carriage of the calibration platedo not work.The fan and the solenoid On the PBC 2 board, the J391490 not work too. The 24V and 5V LEDs are on, but LED1 is off (in all cases). The voltage was measured. All right. Does anyone have any considerations?
