1) System Clock (WorkCentre Pro 412 & FaxCentre 12)
• KS32C61200 RISC PROCESSOR: drives PLL internally and uses 60MHz.
1) System Clock (WorkCentre M15/M15i)
• ARM946ES RISC PROCESSOR: drives PLL internally uses 120MHz and external Bus uses 60 MHz.
2) Video Clock (WorkCentre Pro 412 & FaxCentre 12)
• Fvd = ((PAPER 1SCAN LINE sending time * SCAN effective late /1SCAN LINE DOT #)*4
=(600dpi*600dpi*58.208mm/s*216mm*4)/(25.4mm*25.4mm*76.1%) = 28.697MHz.
•PAPER 1SCAN LINE sending time = SCAN LINE interval/DOCUMENT SPEED (58.208mm/S)
•1SCAN LINE DOT # = MAZ SCAN distance (216mm) *DOT # per 1mm.
2) Video Clock (WorkCentre M15/M15i)
• Fvd =((PAPER 1SCAN LINE sending time * SCAN effective late /1SCAN LINE DOT #)*4
=(600dpi*600dpi*58.208mm/s*216mm*4)/(25.4mm*25.4mm*76.1%)=28.697MHz
•PAPER 1SCAN LINE sending time=SCAN LINE interval/DOCUMENT SPEED (58.208mm/S)
•1SCAN LINE DOT #=MAZ SCAN distance(216mm)*DOT# per 1mm
