2.8
Stacker-full Detection
The sensor (interlocked with the lever) at the paper outlet to the stacker detects a stacker-full state
(about 250 sheets) and stops printing of the ensuing pages.
2.9
Page Size Detection
The four tab pieces are driven according to the setting position of the paper guide through the cam
interlocked with the paper guide of the paper cassette.
When the paper cassette is inserted into the printer, the state of the tab pieces is detected by the
microswitch to recognize the paper size.
2.10
PostScript Board (BOARD-PSBA) Optional
The PostScript board consists of program/font ROM's, an EEPROM, and a LocalTalk interface
control circuit.
(1) Program/font ROM's
The program/font ROM's store the PostScript Level II program and its fonts.
MASK ROM is used as the program/font ROM's.
(2) EEPROM
The EEPROM has a 4-kbit capacity and stores the PostScript's menu settings.
(3) LocalTalk interface control circuit
AppleTalk protocol data is received from the host system via LocalTalk interface.
The LocalTalk interface control circuit consists of a CPU, a program ROM, a SRAM, and a
driver/receiver IC.
