Safety Warnings
When printing, put the printer in a well-ventilated place because resin may smell.
Do not use volatile objects near the printer as they may cause fire or explosion.
When the printer power is on, please do not force shutdown by pressing the emergency power button
on the front of the printer. Forced shutdown shortens the life of the digital light engine and may cause
mechanical failure. Please shut down the printer through a shutdown process such as power off and
automatic system shutdown on the LCD panel.
If metal fragments and other types of liquid leaks into the printer, it may cause mechanical malfunction.
Also, operating the printer with wet hands may cause electric shock. Use protective equipment while
using the printer.
* Latex rubber gloves can also be used in place of the nitrile gloves provided.
The warranty benefits of the printer will be forfeited if disassembled or modified artificially.
Carima will not be held liable for the loss caused by this.
For inquiries regarding “After Sale Service” and product warranty, please contact Team Viewer Service.
There are potential risks to the printer in terms of chemical composition and voltage. To prevent injury on
children and pets, please install the printer in a safe place.
If the printer power cable and USB cable are damaged due to being pulled or stepped on the rough
surface, please note that sparking or voltage malfunction may occur.
In addition, there is a risk of fire due to overheating when the power is turned off.
Setting up a printer in a place with a lot of moisture or temperature changes can cause deformation and
malfunction of the product.
[email protected]82-2-3663-8877
The printer should be used on a hard and flat floor.
When moving the printer, be sure to completely shut down the printer, and then remove the vat and
build plate so that the resin in the vat does not overflow or leak.

PREPARATION AND SETUP
Printing Preparation
Preparation and Setup
To start printing, the resin must be sufficiently filled.
Please prepare resin, cleaned sweeper and build plate.
Resin Refill
* Maintenance - Resin
Press the Start button, check the amount of resin available and refill the resin.
Move the build plate to the origin position to accurately determine the amount of resin.
Pour the resin slowly so that large waves do not occur far from the resin check sensor.
When refilling the resin into the vat, it is recommended to supplement while measuring the amount of
resin.
If too much resin is filled, the printable height may be limited.

Information on maintaining the build plate
To clean the build plate, you can scrape the hardened debris attached to
the build plate by a scraper or a spatula. If you want to print using other
resin after printing, please wipe off the stained resin before use.
Information on the use of sweeper
Before printing, please check if there is any
debris in the gap of the sweeper and remove it
before printing. Printing with foreign substances
may affect the printing result.
Information on the use of resin
Use protective equipment when using resin. Pour resin before printing and
on inevitable occasions, press the 'Pause' button and wait for a complete
stop before slowly pouring the resin into the vat.
