MANTIS User's Guide | Chapter 15: Troubleshooting and FAQs
MANTIS is not dispensing correctly — drops are hanging at the end of the nozzle,
dispenses are sporadic (i.e. the MANTIS dispenses to every other well instead of
every well), or the MANTIS is not dispensing at all.
Sometimes the chips wear out. We recommend that you try dispensing with multiple
chips. If the problem persists, contact support by emailing support@formulatrix.com. If
you are on maintenance, you will be shipped a loaner MANTIS, instructed to ship yours
to support for repairs, and when you receive the repaired device you must ship back the
loaner.
The MANTIS is having trouble washing chips.
Usually this issue is caused by a misalignment of the wash position. To fix this problem,
you will need to edit the sequence file. Contact support by emailing
support@formulatrix.com and a support representative will walk you through the
process.
My computer says the drive is read-only and I can't run the software.
If your computer is showing that the MANTIS USB drive is read-only, you will not be able
to use the software because the software frequently writes to the USB drive. To fix this
issue, copy the contents of the USB drive onto your computer, so that when you run the
software you are running it locally instead of from the USB drive. Or if you are on
maintenance, you can contact support by emailing support@formulatrix.com to get a
replacement drive.
MANTIS is not showing up on my computer's drive list, or I can run the software but
the software can't find the MANTIS.
These problems are caused by USB communication issues. Please contact support by
emailing support@formulatrix.com. If you are on maintenance, they will issue a loaner
device to use while yours is repaired.
MANTIS is not picking up chips from the chip port, or it's picking up chips but not
replacing them correctly.
This issue can be fixed by calibrating the chip port positions.
MANTIS is dispensing drops, but the drops aren't aligned with the wells on my plate.
● Make sure that you have accurately registered your plate definition in the Plate
Type Library. For more information, see Adding Plate Types to the Plate Type
Library on page 14.
● If the plate definition has been accurately entered but the problem persists, you can
fix the deck geometry settings. Go to the Tools menu and select Deck Geometry
Correction, then follow the on-screen instructions. For more information, see Deck
Geometry Correction. For assistance using the Deck Geometry Correction Wizard,
contact support by emailing support@formulatrix.com.
The MANTIS software seems frozen.
● If you are attempting to open or close the dispense design using a spreadsheet
program such as Microsoft Excel, it can take a few moments for the software to
translate your actions. Please be patient.
● Check that you are not in Summary View or Volume Error View. These two
views will "freeze" the rest of the interface. Switch back to Designer View in
order to enable the rest of the software's functionality. To change views, click
the button at the top of the plate designer to display the alternative views.
