speed is slow, the printer waits for
the data with the print heads
capped.
Check the USB's transmission
speed. If the USB connection is
full speed, the speed can be
improved by changing the
conditions of the connection to the
computer as follows, so that the
connection becomes high speed.
(See Check the USB connection
status in the User's Guide.)
- Reconnect the USB cable.
- Connect the USB cable to the
USB 2.0 port.
- Reinstall the driver.
- Change the USB cable to a cable
supporting high speed
transmissions.
- If a hub is used, change the hub
to a model supporting high
speed transmissions.
User Solution
If the printer heads temperature is
40°C or more, the printer prints at
a lower speed. Set the ambient
temperature to 20 to 25°C
(recommended temperature), and
leave the printer for one hour or
more before starting the print.
Remove any additional devices
connected via USB.
Connect the printer to a computer
satisfying the recommended
operational environment for your
RIP software. For the
recommended operational
environment, contact the
manufacturer of your RIP
software.
Terminate other software
applications, for example,
anti-virus software.
