Explanation
In the CT emulation over a
twinax interface, the printer
received a non-printable
character.
The printhead or power supply
is approaching a hot state. Half
Speed Mode aids the cooling
process and should permit
completion of print jobs.
Half Speed Mode helps prevent
a PRINT HEAD HOT or PWR
SUPPLY HOT fault, which will
stop the printer.
