3. Full-color one-sheet print
PVREQ signal (image demanding signal) for each color is produces based on A-surface ITB home position detection signal (I_TOP1A). The image is formed based
on this PVREQ signal.
F-7-92
4. Full-Color 2-Sheet Continuous Printing (2-image printing) (See after-mentioned note)
PVREQ signal (image demanding signal) for each color is produced based on the A-surface ITB home position detection signal (I_TOP1A) and the B-surface ITB
home position detection signal (I_TOP1B). The image is formed at constant speed based on this PVREQ signal.
The image is formed in order based on I_TOP1A for the first surface, I_TOP1B for the second surface.
F-7-93
2-image printing is the print with image forming by 2 surfaces on the ITB. 2-image printing is available for up to LTR size (sub scanning direction) that is equivalent
to the interval between two home position detection signals.
5. Monocolor Continuous Printing
The image forming position on the ITB is arbitrary because the monocolor printing has single color. The DC controller does not perform the ITB home position
detection at monocolor printing.
After determining the home position by the timer inside the DC controller, PVREQ signal (image demanding signal) is produced. The image is formed based on
this PVREQ signal.
