(1) CPU The CPU is PowerPC750CXe, a 64-bit bus RISC processor, which inputs an 100-MHz CLK (= BUS CLK), and operates at 450MHz that is 4.5 times the input. (2) Cache PPC750Cxe has its cache only inside of it. Speed: Same as CPU Core CLK speed Capacity: Primary Cache: 32 K bytes in D-cache capacity, 32 K bytes in I-cache capacity Secondary Cache: 256 K bytes (3) ROM ROM is to be inserted into the two 168 pin DIMM slots. The slot A is for program ROM and the slot B is for Japanese kanji fonts.

3.1.2 Engine maintenance mode Three modes from Level 1 to Level 3 are in the engine maintenance mode. Level 1 is a mode that checks the media transport and basic movement of the print system. Level 2 checks the counter for consumables and tests the correcting function of color displacement, and is a mode that does not require special knowledge. Level 3, on the other hand, requires special knowledge for handling the process parameter setting and is contained in the independent experimental element of PU.

3.4 Paper Thickness Detection Sensitivity Adjustment and Media Thickness Detection Value Check Outline: The sensitivity of a micro displacement sensor used for detecting media thickness varies from one to another. Therefore, to ascertain the sensitivity in advance, check the output value of the sensor by passing media of known thickness through the printer equipped with the sensor. The sensitivity is fixed based on the output value.
PAGE 102
3.4.2 Setting 3.4.2.1 Menu Setting (1) Power on the PC.
