1. Contents
The bypass paper feeding capacity for the 1560 has been changed from single to stack feeding of 60 sheets. Moreover, for energy saving, when there has been no input for a fixed time, the main switch will now automatically be turned "OFF". For bypass feeding area the 1560 uses the same bypass paper feeding device as the 2060 (2860) and drive is provided through the main motor to the aligning roller unit. As new electrical parts, there is an ON/OFF electromagnetic clutch in the feeding roller and a bypass switch for paper-empty detection. (The time until it goes off can be adjusted.) The consumable parts and options are all common to the 1550 ones. However, when using the key counter mounting kit KN-1550K, a hole has been added to the copier cover for easy installation.

4. Operation Explanation "Bypass paper-feed copying"
(1) Insert the paper in the bypass paper-feed slot. Switch ON the bypass
The bypass LED of the control panel lights up. (2) Press the PRINT key
The main chager/transfer chager/separation charger/transfer bias/discharger lamp/LED eraser lamp are turned ON/and the optical system fan motor rotates at a high speed. The main motor comes ON~the drum/developert/heat roller/and paper-exit roller rotate.
(3) Bypass paper-feed operation The manual feed clutch comes ON~the bypass pick-up roller/paper feed roller rotate. Aligning operation (the paper reaches the aligning roller)~switch is turned on paper stop. After a fixed time, the manual feed clutch goes OFF~ paper-feeding is finished.
(4) Thereafter, the paper-feeding operation is the same as with the cassette.
5. Disassembly and exchange
5. 1. Removal of door switch and main switch (1) Remove the rear cover. (2) Open the front cover and raise the upper unit. (3) Remove the bypass paper-feed cover (2 screws). (4) Remove the front support bracket (1 screw) of the bypass and take out the bypass tray. (See
Illustration A.) (5) Remove the rear support bracket (1 screw). (See Illustration A.) (6) Remove the bypass paper guides (upper/2 pieces) (1 screw each). (See Illustration A.) (7) Remove the 2 screws of the bypass separation pad bracket. (See Illustration B.) (8) Push down the pick-up roller and take out the separation pad bracket by pushing down the paper
stop lever and the arm of the paper sensor. For the removal of the bypass paper feed roller, the separation pad and the clutch, details are given
later.
