The IPC controls the resolution of the printer as follows.• FIFO/S-RAM ControlPicture Edit Coding Gate Array uses FIFO for Smoothing & Laser pulse width control, and S-RAM forSmoothing Data and interface controls.• Serial Communication Port for LP InterfaceIt provides 1ch Serial Communication Port interface for the Printer Mechanical CPU.2. SORT Memory Control Gate ArrayBRIDGE (DZAC000233) is a SORT Memory Control Gate Array and provides the data transfer controlfunction between Sort Memory Control, DANCE, CODEC for Image, and System.• DMA ControlIt is used to transfer the following data.• S-DRAM ControlIt generates S-DRAM Control Signal for SORT Memory and Refresh Control when the power is ON. itdoes not backup the Page Memory.3. PWM Control LSIPM-1075 (IC26), which is a PWM control LSI, converts an 8-bit input digital signal into an analog signalwith 256-scale pulse width. The conversion allows modulation of pulse width in recorded data,transferring the data to LSU, enabling multiple-value recording.The pulse width is determined by the Picture Edit/Recording Gate Array (DANCE).The function performs centering, reading, and trailing edge modulation in the pulse.4. Optional Memory for Image SideThe Optional Memories are:• Memory PC Board (SODIMM) → DRAM Card (8/16/128 MB) for Sort memoryInstall the DRAM Card for Sort memory to CN151 on the SORT PCB.16 dot/mm x 15.4 line/mm : Report data15.4 dot/mm x 16 line/mm : Report rotation recording data600 dpi x 600 dpi : Copy, Printer Interface & PDL InterfacePicture Edit/Recording Gate Array (DANCE) ←→ CODEC for Image (PM-22c) : Bus SelectionCODEC for Image (PM-22c) ←→ SORT Memory (S-DRAM) : Compress, RestoreSORT Memory (S-DRAM) ←→ System Memory (DRAM) : PC Scanning
