Daily Maintenance Instructions
1.
Keep the working environment of the printer clean and ventilated, and clean dust and
ink on the printer periodically.
2.
Keep the work surface clean. Every time before starting it up, check whether the
working board is cleaned, to avoid scatching the print head.
3.
Inject lithium base greases into the slider by grease gun every forty hours operation, to
reduce its frictional resistance against the guide rail and extend its service life.
4.
Maintain an appropriate belt tightening of the ink carriage timing belt, which can be
adjusted after removing the upper left end cap. After the adjustment, connecting screws
must be fixed tightly.
5.
Every time after finishing refilling ink, make sure the cover of the main ink tank is
screwed tightly. Wipe off residual ink on the tank.
6.
For positive pressure printing, after wiping the printhead, flash spray for around 20
seconds first before printing pictures, to achieve sound meniscus formed by ink droplets
in the nozzle.
7.
During the interval of printing pictures, printer please keep the print head under the
state of flash spray, in order to guarantee a smooth nozzle.
8.
The area around the orifice must be maintained clean,. No residual ink, dust or fiber is
allowed. Orifice shall not be scratched.
9.
Since the ink and the cleaning fluid contain strong solvent, they mustn’t contact
electrical components and wires. Were ink or cleaning fluid spilled on them accidently,
they would be wiped off cleanly as soon as possible.
10.
Clear liquid waste in the liquid waste box in time.
11.
When the suck-back phenomenon occurs to the printer and ink appears in the air tube
of the minor ink cartridge, the printer should be stopped immediately to discharge the
ink from the air tube and the waste liquid tank (safety bottle) and replace the air tube
with a new one.
12.
Every day before the startup and shutdown, it is recommended to print nozzle test chart
to check whether the nozzle is in normal condition. Provided that ink outflows brokenly,
press the ink or clean the nozzle to make it work properly.
