Problems With Graphics
The message INSUFF MEMORY appears and graphics cannot be
printed.
The full print buffer or the receive buffer setting needs to be
changed. To correct this error, change the FULL PRINT setting
in the SYSTEM CONFIG option of SelecType Level 1 or the
RX-BUFFER SIZE setting in SelecType Level 2 as described in
Chapter 4.
The printer does not have sufficient memory available for the
task you have given it. It may be necessary to simplify the page
you are trying to print or add more memory to the printer. Press
CONTINUE
or
RESET
to clear the error. See Appendix A for
