Starting Printing
To begin printing:
➢ On the printer interface, click the red button to switch the printer to online
When switching the printer to online mode, a message is displayed if a
maintenance activity is required to ensure optimum printing quality. (See
"Routine Maintenance Schedule" on page 4-42.) Maintenance notifications
can be disabled/enabled from the Options menu.
In the printer interface, the printer mode changes from Idle to Pre-print, as the
printer's components prepare themselves for production:
• The print block is heated.
• The UV lamps are powered and they warm up.
When printing begins, the print manager program sends a number of slices to
the printer-control application. This fills the buffer between the print manager
and the printer to ensure continuous printing. As each slice is printed as a layer
on the build tray, another slice is sent to the printer.
Depending on the size of the 3D print(s) to be produced, printing can take
between several hours to several days. As long as there is enough model and
support material in the supply cartridges, printing proceeds automatically until
the job is finished.
J850/J835 printers use up to seven different model-material cartridges to
produce 3D prints. In addition, a support-material cartridge is required. If
additional cartridges are installed and they are not immediately needed for
printing, the printer interface indicates this (see "Printer Interface Color Key" on
the next page).
