Printer Repair Questions? Ask IT Technicians for Answers ASAP
Hello, my name is ***** ***** I'll be assisting you today.
Luckily, this error only happens to certain models and troubleshooting is fairly simple but it means that there is a voltage issue somewhere.
First, power off the printer. Unplug the power cable. Wait 30 minutes to allow the static to leave the unit. Then reconnect the power cable and turn it on. If the message doesn't go away, make sure that the power supply is working properly. If the power supply is okay, then the voltage of the printhead is not right and you will need to replace the printhead. If that does not resolve, then check for the cable continuity between the carriage relay PCB and the main controller PCB by replacing the cable. If that doesn't work, replace the carriage relay PCB. Then, lastly if no resolution, replace the main controller PCB.
