Meter Error #1956 on boot.
Opened a Ticket with Brian@PB. PB says that error is a “spit timeout” error, meaning that the printhead didn’t operate as quickly as it was supposed to.
Technician Steve called back 10min later, but the machine was working by then.
Ran Tape Maintenance test and Cleaned Printer Nozzles. Guess I’ll just have to wait and see if it happens again.
