Printing is slow. The
carriage moves
sometimes only.
USB connection speed
When the data transmission
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.
- Install the last firmware version.
- Check that the ambient
temperature at the installation
location meets the operating
conditions (35 degrees or lower).
- Check the COOLINGFAN,MW
operation in the ACTUATORS
menu.
- Check that the COOLING
FAN,MW connectors are
connected correctly.
- Check the connection of HEAD
CABLE,MW connectors on the
HCB1M and the print heads.
- Check the connection of
CARRIAGE FFC,MW connectors
on the HCB1M and the IPB5.
- Check the connection of ROBOT
CABLE,MW connectors.

Printing is slow.
During print, print
heads are capped

High-temperature
environment
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.
- Check that the ambient
temperature at the installation
location meets the operating
conditions (35 degrees or lower).
- Check the COOLINGFAN,MW
operation in the ACTUATORS
menu.
- Check that the COOLING
FAN,MW connectors are
connected correctly.
- Check the connection of HEAD
CABLE,MW connectors on the
HCB1M and the print heads.
- Check the connection of
CARRIAGE FFC,MW connectors
on the HCB1M and the IPB5.

Computer
specifications
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.
