GENERAL PRECAUTIONS FOR INSTALLATION/SERVICING/ MAINTENANCE The installation and service shall be done by a qualified service technician. 1. When installing the Paper Feed Pedestal KD-1025 to the equipment, be sure to follow the instructions described in the "Unpacking/Set-Up Procedure for the KD-1025" booklet which comes with each unit of the KD-1025. 2. The KD-1025 should be installed by an authorized/qualified person. 3.
16.During servicing or maintenance work, be sure to check the nameplate and other cautionary labels (if any) to see if they are clean and firmly stuck.

3. GENERAL OPERATION 3.1 Driving System and Feeding Operation The Paper Feed Pedestal (PFP) mainly consists of the drawer, pickup roller, feed roller, separation roller, transport roller, and drive systems for these components. • Feeding/Transport system The PFP motor drives the pickup roller, feed roller, and transport roller which are located in the feeding area. • Drawer tray system This system raises and lowers the tray.
3.2 Description of Operations [A] From power ON to ready (1) When the equipment is turned ON, the power is also supplied to the feeder unit. And when the power is supplied, the feeder unit detects and judges the clock frequency output from the LGC board on the equipment to control transport speed of the unit. (2) After that, the tray-up motor (M2)/(M3) is turned ON to raise the corresponding tray.
3.3 Error Detection [A] Jam detection (1) Paper jams (E150), (E160) and (E300 to E360) occur in the following cases. • Feed sensor (S2)/(S3) is not turned ON within a specified period of time after the feeding is started. • The leading edge of the paper does not pass the feed sensor (S2)/(S3) in the transport path within a specified period of time. (2) Open the side cover of the PFP and remove all the paper remaining on the transport path and close the side cover to clear the paper jam.
