ac. Use the scraper tool included with the Formlabs Finish Kit to move across
the resin tank's elastic layer, pulling resin toward the spout.
ad. Once all resin passes through the filter, dispose of the dirty filter and pour
the resin back into the tank.

Troubleshooting and Repair by Non-Skilled Persons

In the case of an error or abnormal activity with the Form 2, reference the following
errors, causes, and proposed solutions. Complete the initial troubleshooting
steps and carefully document all results. Contact Formlabs or an authorized
reseller for additional assistance.

7.4.2 Print Failures and Errors
Print failures can manifest in different ways and originate from different causes.
Check the model's configuration in PreForm, the cleanliness of the optical
surfaces, and the printer's operating condition according to 6. Maintenance
and 7. Troubleshooting, including the proposed solutions below.

Solution
To troubleshoot a closed bite valve:
1. Close the vent cap and remove the
resin cartridge from the printer.
2. Turn the cartridge upside down to
inspect the bite valve.
3. Squeeze the valve a few times to open
up the seal and enable resin flow.
4. If squeezing the valve does not enable
resin flow, carefully use the tip of the
tweezers from the Finish Kit or Form
Wash to push through the opening to
enable resin flow.
5. If the bite valve seal remains closed
after troubleshooting, contact Formlabs
Support for additional help. Submit
photos of the bite valve seal with
your request.
See 6.4.1 Maintain the LevelSense Board
Consider the following:
• Check to see that you do not have
other open instances of PreForm.
• Save any files before restarting PreForm.
• Re-connect your printer to establish a
proper connection
If print failures persist after following these steps, contact Formlabs or a certified
distributor for additional guidance. In order to introduce a known good variable
to isolate any printing issues, run a Formlabs test print, for which the file is
available online. Provide clear, focused photographs of the test print to help
diagnose the issue.

Solution
Consider the following:
• Check the model in PreForm.
• Check for pauses in printing.
• Check the resin tank for debris
or damage.
• Check cleanliness of optical surfaces.
• Check the build platform's stability.
Consider the following:
• Print with a base and supports.
• Check the print's surface area.
• Check the resin tank for debris
or damage.
• Check cleanliness of optical surfaces.
• Check the build platform height.
• Decrease ("-") the Z Offset value to
lower the build platform closer to the
resin tank bottom.
Consider the following:
• Increase the base height in PreForm's
advanced settings.
• Check the build platform's height.
• Increase ("+") the Z Offset value to
raise the build platform further away
from the resin tank bottom. Raising the
build platform provides more space for
the base to build.
Consider the following:
• Check the resin's shelf life.
• Check the resin tank for debris
or damage.
• Check cleanliness of optical surfaces.
• Check for restricted resin flow.
