Printer Memory Option
The printer memory option increases the amount of dynamic
random access memory (DRAM) in the printer. Additional printer
memory allows the printer to print complex jobs and operate more
efficiently. Anything that is stored in printer memory is lost when
the printer is turned off.
You can buy optional cards with 4MB, 8MB, 16MB, 32MB and
64MB of memory.
