Paper is picked up from the cassette under the control of the CPU on the DC controller PCB and using the drive of the main motor (M1). When the cassette pickup
solenoid (SL2) goes ON, the drive of the main motor (M1) is transmitted to the cassette pickup roller assembly
to rotate the cassette pickup roller.
When the cassette pickup roller rotates, a single sheet of paper is separated from the stack by the separation claws of the cassette, and is sent as far as the registration
roller by way of the feed roller.
After the paper passes a registration sensor (SR11), the paper reaches the registration roller. At this time the registration roller is at rest, causing the leading edge
of the paper to butt against it to form an arch.
The DC controller PCB turns on the registration clutch (CL1) at specific timing to transmit the drive of the main motor to the registration roller, thereby moving
the paper ahead. The paper reaches the delivery tray after moving through the transfer, separation, and fixing/delivery assemblies.

7.3.2 Retry Pickup

LaserBase MF6530 / / LaserBase MF6540PL / LaserBase MF6550 / KaserBase MF6560PL / / LaserBase MF6580PL
If the registration sensor (SR11) does not detect paper within a specific period of time after the cassette pickup roller has started to rotate, the machine will start to
rotate the cassette pickup roller once again to execute a retry pickup operation.
If the registration sensor (PS102) still does not detect paper within a specific period of time after the machine executes a retry pickup operation once, the machine
will identify the condition as a jam and will indicate a jam message on the LCD of its control panel.
7.3.3 Detecting the Size of Paper
0011-4055
LaserBase MF6530 / / LaserBase MF6540PL / LaserBase MF6550 / KaserBase MF6560PL / / LaserBase MF6580PL
The cassette paper size detection is performed using the registration sensor (PS102) based on the length of paper. In fax mode, if paper of a size different from the
size selected from the control panel is placed, the DC controller will identify a paper size mismatch at the end of printing and indicate a message on the LCD.
