Failure Cause Solution Remark
⚫An axis has abnormal
sound during
initialization
⚫Manual three-axis
motion can’t touch the
limit switch
⚫The only method is to
turn off the power
➢Confirm the fault
axis
The axis that causes the initialization failed is the
fault axis (initialization sequence: Z-X-Y)
Normal initialization:
➢Z axis collides downwards with
limit once;
➢X axis collides backwards with
limit twice;
➢Y axis collides rightwards with
limit twice;
➢LED light is on
➢Limit switch of fault
axis is
deformed/damaged

Turn off the power, and move the XY axis manually; if
the fault axis can’t touch the limit contact or no
sound is made after touching the limit contact, the
limit is damaged and should be repaired or replaced;
if the failure still exists, process as follows;
✓Remove and
replace X limit
✓Remove and
replace Y limit
✓Remove and
replace Z limit
➢Do not break off the limit with
hands if it can’t touch
➢Limit wire, motor
wire broken, plug
loose, needle
retreated
Turn off the power, remove the rear panel and check
if the limit (on mainboard side) and motor wire of
the fault axis is broken; if not, re-plug the
limit/motor plug of the fault axis

Turn off the power and replace the motor of the fault
axis
✓Remove and
replace X motor
✓Remove and
replace Y motor
✓Remove and
replace Z motor
➢Check which axis isn’t moving
normally during initialization,
touch the limit by hand, and
check whether it can resume
normal initialization
➢Mainboard
damaged Turn off the power and replace the mainboard ✓Remove and replace mainboard
➢Mainboard adapter
board damaged Turn off the power and replace the mainboard
✓Remove and
replace mainboard
adapter board
➢CPU damaged Turn off the power and replace the CPU ✓Remove and
replace CPU
➢Display damaged Turn off the power and replace the display ✓Remove and
replace display

7UP 300 Service Manual
Failure Cause Solution Remark
⚫A certain axis has no
action during initialization
and the motor has no
motion sound
⚫Initialization is always in
the state that can’t be
finished
⚫The only method is to
turn off the power
➢Confirm the fault
axis

The axis that causes the initialization failed
is the fault axis (initialization sequence: Z-
X-Y)
Normal initialization:
➢Z axis collides downwards with
limit once;
➢X axis collides backwards with
limit twice;
➢Y axis collides rightwards with
limit twice;
➢Motor wire of fault
axis broken, needle
retreated, plug loose
➢Check if the motor of
the fault axis is
damaged
Turn off the power, check if the motor wiring of
the fault axis is damaged, and if the plug is broken;
if not, remove the mainboard and check if the
motor wire is broken or if the plug is loose
Turn off the power, open the rear panel, plug an
intact motor into the motor terminal of the
mainboard, and then initialize and test the motor
for damage. Replace the motor of the fault axis
✓Remove and
replace X limit
✓Remove and
replace Y limit
✓Remove and
replace Z limit
➢After abnormal initialization by
touching the limit with hand, push
each axis by hand to see if there is any
power failure
➢Mainboard damaged Turn off the power and replace the mainboard
✓Remove and
replace
mainboard
➢CPU damaged Turn off the power and replace the CPU ✓Remove and
replace CPU

8UP 300 Service Manual
Failure Cause Solution Remark
⚫The machine
directly powers
off and restarts
when the
initialization
function is
triggered in any
method
⚫The cause of this
fault is a short
circuit
➢26P colour cable
➢Platform FFC short
circuit
➢Platform adapter
board damaged
➢LED light short
circuit
➢
Height aligning cable
short circuit
Turn off the power and replace the 26P color cable
Turn off the power, replace the platform adapter
board
Replace the LED light cable

there is obvious burning
during initialization, and the
light appears
➢Short circuit of
aluminum substrate
Turn off the power, and replace the aluminum
substrate assembly
✓Replace the aluminum substrate
assembly
➢nozzle adapter
board short circuit
➢nozzle CFC cable
adapter board
➢nozzle FFC cable is
damaged or contact
is poor
Turn off the power and replace the nozzle adapter
board
Turn off the power and replace the mainboard
adapter board

board
✓Replace the mainboard cable
adapter board
✓Replace the FFC-Y axis adapter
cable
➢Short circuit of
internal components
of the nozzle
Turn off the power and replace the nozzle assembly ✓Remove and replace the nozzle
assembly
➢Power cable or
signal cable of
screen short circuit
Turn off the power, check if the power cable and
signal cable are damaged, and if the connector is
broken or the plug is loose. If yes, replace the
power cable, signal cable / re-plug
✓Replace the power cable and
signal cable
➢Mainboard
damaged Turn off the power and replace the mainboard ✓Remove and replace mainboard

broken
✓Remove and replace display
✓Remove and replace
power/signal cable
Failure 03: Initialization failed: direct power off
Back to Directory

9UP 300 Service Manual
Failure Cause Solution Remark
⚫Initialization can be
done normally, but
abnormal sound is
caused by slight friction
of the faulty axis during
initialization and
printing
➢Fault axis lacks
lubrication
If it is Y/X/Z axis, check if there is any jam or dry
noise; if yes, lubricate the fault axis bar with
industrial grade lubricating oil directly
If it is Z-axis, remove the rear panel first, and
then apply the industrial grade lubricating oil
evenly to the screw motor
✓Disassemble the rear
panel
➢Y axis abnormal
sound
Turn off the power, manually pull the Y-axis
nozzle holder, and check if the Y-axis motor
pulley is loose
Y-axis light bars not parallel, too tight
✓Remove and replace Y
motor
✓Replace Y-axis light bar
➢X axis light bar
abnormal sound
Turn off the power, manually pull the Y-
axis, and
check if the X-axis has obvious blackening or
axial scratches
✓Remove and replace X-
axis light bar
It is difficult to
replace Y-axis
linear bearing; it
is recommended
to replace the Y-
axis assembly
➢X-axis pulley
abnormal sound
Turn off the power supply and manually pull the
Y-axis to check if the X-axis motor pulley is loose
Place the belts on both sides of the pulley, and
pull the Y-axis back and forth five times to check
if the belt has obvious displacement and wear
✓Replace X-axis belt
✓Replace X motor
➢Z axis abnormal
sound

Check if the 26P color cable with black net under
the platform falls off
Failure 04: A certain shaft has slight abnormal sound during
initialization, but initialization can be done
