Printing from tray 2
When the dc controller PCA receives the print command, the main motor (M101) and scanner motor
start their rotation. When the main motor reaches its prescribed speed, the feed roller clutch (CL101)
and tray 2 pickup solenoid (SL101) are activated. (The main motor rotation drives the tray 2 pickup
roller, tray 2 feed roller, tray 2 separation roller, and paper-feed rollers.)
The tray 2 pickup roller, which the pickup solenoid activates, rotates once and picks up the media in
the tray. The separation roller prevents additional sheets from feeding with the first sheet, and the
media is fed to the pre-feed sensor (PS102).
The sheet then reaches the registration assembly, where its skew is corrected. The sheet then
passes through the transfer, separation, and fusing stages; through the delivery unit; and to the
output bin.
Tray 2, 500-sheet feeder, and 1,500-sheet feeder media-size detection
Three switches detect the size of media in the cassette. The switches are active when the cassette is
placed in the tray 2 feeder, 500-sheet feeder, or 1,500-sheet feeder. The dc controller PCA
microprocessor detects the size and presence of the media by reading the combinations of the
switches.
