    been running a hp 3050 for the pas year or so. recently moved the machine to a new location and seem to not be able to make it work. gives a consistent i2c communication error, or 'failure to communicate with engine'. have checked all connections, look OK. what am i missing, need help.

    Hello, i2c comunication error can be many things, the most comun its due to the ink cabinet, can be tmb1 or ps.
    Failure to comunicate with engine normaly is the pop i but also can be ecn.

    Hi,
    check the TMB, try to disconnect the TMB2 and start the press in 4 colors...
    Check 5 volts on this board
