Caution
Always wait at least 5 seconds after turning off the power before turning
it on again.
Do not turn the power off while the printer is printing as this may cause a
paper jam and adversely affect the printer.
The printer performs self-diagnosis at start-up to check its hardware and
software. If the printer should find any problems, the display will change
to show the corresponding error message. See
The display shows several messages quickly at start-up. If the printer
detects no errors, the printer initializes. This will take several minutes
during which time the LCD will display the following message:
LJ WAIT 001P T1
AUTO
K C M Y
Once the printer has finished initializing, it automatically goes on-line
and the message changes to show the current printer status and
settings as shown below:
