Switch power on located in the back of the printer to power on the device. Once the printer is switched on it should remain on unless it will not be used for a significant amount of time (>60 days). 

UI will begin to power up. This may take a minute or two for the screen to come on. When the UI is booted up the 3D Systems logo will appear and then the Status screen will appear.

The UI will instruct the user when it is time to change the Waste Bag. Follow these steps to change the waste bag.

 NOTE: Even though  the waste bag may not appear full when the user is notified to change it, it is highly recommended to replace the waste bag when prompted to avoid unnecessary overflow and mess. When waste bag has been changed ensure you confirm the level has been reset to zero.

1. Verify that the printer is in READY.
2. Select Materials tab.

3. Select the  next to the Waste Bag status bar.

4. Wearing protective Nitrile gloves, open the MDM drawer.
5. Remove waste bag and dispose of bag according to local regulations.
6. Inspect the waste bin for any remaining waste. If necessary, wipe out any waste that exists with the lint free cloth and isopropyl alcohol.

NOTE: If the waste bag is stuck to the liner when you attempt to remove it, replace the entire liner and bag to prevent the bag from tearing and causing material to leak into the receptacle. Waste bags can be ordered using part number 310248-00. With each order you will receive 30 bags and 1 liner.

7. Confirm on the printer UI when you have completed replacing the waste bag.

The Waste Bag routine can also be accessed from the Operator Maintenance window.

Select Tools>Operator Maintenance

When a material cartridge is empty and needs to be replaced, or if a partially filled container needs to be replaced with a full container, perform the following procedure.

NOTE: It is important to verify the type of material currently in the MDM before proceeding with these steps.

Removing Material Cartridge

	NOTE: Cartridges cannot be removed from a cold printer. The printer must be warm before drawer will open and cartridges can be removed.
	NOTE: The software verifies that material cartridges are genuine to prevent possible compromised part quality and print head damage from the use of non-genuine material cartridges.  Material cartridge information and certain printer performance parameters are collected, but no personal or design data are collected.

The MDM drawer (A) is a push/push mechanism. Push to open drawer, push to lock drawer.

1. Open the MDM drawer by pushing in at the recessed dimple.

2. Pull the MDM drawer open.
3. Turn the material cap (B) a 1/2 turn to clockwise to tighten the vent cap.

4. Press the release button (C) on the front. You will hear the cartridge release. Pull the cartridge out of the slot.

5. Dispose of the empty cartridge according to local regulations.
6. Wearing nitrile gloves and either protective sleeves or a lab coat to protect arms, use a disposable paper towel and wipe all material from the container seal assembly, if necessary you can use some isopropyl alcohol on the paper towel to wipe up the excess material.

NOTE:  It is important to always wear nitrile gloves and either protective sleeves or a labcoat to protect arms when coming in contact with materials to avoid getting materials on skin. Contact with skin may cause an allergic reaction.

Installing New Material Cartridge

NOTE: Cartridges cannot be installed into a cold printer. The printer must be warm before drawer will open and cartridges can be installed.

To place a material cartridge into the MDM, perform the following steps:

1. Obtain a new material cartridge ensuring that it is the same material as currently installed in the MDM.

2. If drawer is not already open, push to unlock drawer.
3. Pull open the MDM drawer.

NOTE: The steps to install a support cartridge are the same as installing a part cartridge.

NOTE: To install cartridges into the MDM drawer properly ensure that the small cap be installed away from the user.

NOTE: It is important to verify the cartridges have been audibly clicked into place, have material in them, and the cartridge caps properly ventilated; otherwise the printer may not be able to pull material from the bottles, potentially resulting in the following fault codes:

4. Place cartridge in slot and push down until you hear it click in place.

5. Vent each cartridge by loosening the material cap (A) by a 1/2 turn counterclockwise.

6. Close the MDM drawer (B), by pushing in the dimple at the top until it’s latched securely.

7. Check the material level under the Materials tab (C) on the UI to ensure cartridge is seated properly into MDM and ready to print.

NOTE: Contact certified reseller partner or 3D Systems Customer Support when the UI continues to report an empty cartridge even though the cartridge is non-empty and is seated properly in the MDM.  Contact your certified reseller partner first or contact 3D Systems Customer Support, whose contact information can be found here.

NOTE: Make sure you are wearing Nitrile gloves and protective clothing before performing any of the following procedures. Always protect yourself from possible exposure to materials. Always wash hands thoroughly with soap and water after handling parts and/or material. Never eat or drink without washing hands first.

1. Ensure the printer is turned on and the Printer State is in Ready or Standby mode.

2. Select the Access Platform button next to the light bulb icon on the printer touch screen.

NOTE: The Access Platform button will not be available to select if the printer is not ready for the user to access the print platform.

NOTE: When selecting the Access Platform button, if the printer is completing maintenance, there may be a delay in accessing the platform. The printer will notify the user when the top door is unlocked and access is allowed.

3. The printer will move into position in order to allow access to the print platform. When prompted, open the door to access the print platform.
4. Lift to remove the platform.

5. Install clean print platform. Close top door. If it is placed correctly the platform will automatically lower and clamp the print platform in place.

6. A message will display (see below) asking user to confirm that the platform is clean, verify the platform is clean.

NOTE: Always be sure you are installing a room temperature print platform that is clean on both sides to avoid any printing issues. Also, confirm that the print platform is free from damage due to any drops or dings. Protruding metal on the platform may come in contact with the printhead and cause severe damage.

For each VisiJet M2 material, the "General" build styles in 3D Sprint are designed to give you accurate prints right out of the box. Please use the "General" build style first and foremost to achieve part accuracy. However, if after measuring your parts you find that you have issues achieving accuracy, you may use the "Scale and Offset Wizard" in 3D Sprint to troubleshoot such issues.

Each ProJet MJP 2500 printer will vary slightly in accuracy. If you have multiple printers, you may need to set the accuracy for each one separately. To do this, click the "Printer" icon in the upper left corner, connect to a specific printer, and run the steps in this section for each printer. Additionally, you will need to run the wizard for each Material,Print Mode, and Build Style combination you use.

1. Click the "Load Reference" button to load the accuracy models that will be printed. 
2. Print the reference build on your ProJet MJP 2500, then post process the parts.
3. Click the "Printer Tools" button, then select the "Printer Settings" button. 
4. In the "Printer Settings" window, select the build style you used to print the reference build, then select the "Scale and Offset Wizard" button. 
5. Measure each part using calipers, micrometer, or height gauge, then input the measurement values to corresponding boxes in the "Scale and Offset Wizard". Each measurement is repeated 4 times. Be sure to input the values for parts labeled with X, Y, and Z before selecting the "Next" button.

NOTE: Before measuring, wipe each end of the measurement part with a paper towel to remove excess wax remaining after post processing. Also be sure to wipe clean your measurement device before measuring.

6. Once all measurements are complete, select the "Next" button.

7. You can now see the calibrated slope and offset values. If you calculate a corrected slope and offset on your own, be aware that the offset range will be limited to [ 0, -0.002 ] inches. 

8. Select "Apply", and 3D Sprint will allow you to change the name of your new "Build Style". By default, the syntax includes build material, print mode, and the date. You may add to the printer name as well if you have more than one ProJet MJP 2500 printer.

9. Be sure to press the "Set" button instead of closing the printer settings window. Pressing "Set" will not only set this new build style for your current 3D Sprint build, it will also save the build style for future use.
10. You will now be able to select this style from the "Build Style" menu going forward, allowing you to build with these scale factors at any time.
11. Remember that the Build Style is tied to the build material and print mode you are using. If you use a different print mode, build material, or printer, you will need to run this wizard again for that combination. The software will automatically create "name the new build style", but you can click the "Rename" button to rename it.

12. When you select this build style in the future, you can verify that this is the style with scale factors applied by looking at the scale and offset fields in the "Printer Settings" window.
13. Print your next build using this new build style. The accuracy of your parts should now be slightly closer to perfection.
