• To improve exchangeability, the pick-up roller, feed roller, and separation roller are held in position on one side. At the time of
replacement, remove the paper tray and release the claws on each roller to remove each of the three rollers.
• For details of the applicable replacement procedures for the pick-up roller, feed roller, and separation roller and the Service Mode, see "

11.3.4 Paper feed retry control
• If the specified sensor is unable to detect the paper even after the lapse of a predetermined period of time after the start of the paper feed
sequence, the machine determines that there is a paper misfeed. To reduce possibility of paper misfeed, if a paper misfeed is detected
during a print job under the following conditions, the paper feed sequence is performed again (retry) only once. The feed roller is
temporarily stopped, and is then turned again. A paper misfeed results if the specified sensor is still unable to detect the paper even after
the paper feed retry sequence, the machine determines that there is a paper misfeed.

11.3.5 Feed roller speed reduction control
• During multi-print cycles, the target printed pages number is maintained due to correction of the transport speed variations and a proper
paper-to-paper distance.
• Measure the time that is taken from starting paper feed to the paper feed sensor ON. If the paper-to-paper distance is too narrow, the paper
roller is decelerated for a predetermined time, so that a proper paper-to-paper distance can be achieved.
• Feed roller speed reduction control is implemented when paper is fed from the following paper trays.
