f. EEPROM (IC4, IC5)

It possesses 32K bits of memory, and it allows erasing and writing of data. It is used to retain data

(various settings; printing environment, number of pages) after power is turned off.

When installing a ROM DIMM for version up to the slot (J1/J2/J3), the functions of the mounted

built-in program ROM will be stopped and its contents will be replaced by the contents held in the

newly installed ROM DIMM. (You need not remove the built-in program ROM.)
