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 10
seconds first before printing pictures, to achieve sound meniscus formed by ink
droplets in the nozzle.
7. The area around the orifice must be maintained clean,. No residual ink,dust or fiber
is allowed. Orifice shall not be scratched.
8. 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.
9. Clear liquid waste in the liquid waste box in time.
10. 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.

head maintenance instructions are as follows:
1. In using the printer, please use the ink appointed by the manufacturer. Do not change
the ink at will, or it might lead to malfunction of print head.
2. When the device stops running, maintenance methods of different sorts should be
adopted in accordance with the length of downtime:
