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.

The deliver tray has a delivery paper full sensor (SR10) to detect that the delivered sheets are stacked fully.

When the total height of the delivered sheets reaches the specified value and the delivery paper full sensor (SR10) turns on, this machine detects occurrence of an

error and displays an error message on the LCD.

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 (SR11) still does not detect paper within a specific period of time after executing a retry pickup 3 times, 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

iR1020J / iR1024J / iR1020 / iR1024 / iR1024A / iR1024N / iR1024F / iR1024i / iR1024iF

The cassette paper size detection is performed using the registration sensor (SR11) 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.
