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.
(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.

<Notes>
1. When installing the clutch, align the end face of the clutch to the shaft groove and align the
hexagonal screw to the milling cutting surface. Insert the projection of the clutch and the gear arm in
the hole of the bracket. (See Illustration I.)
2. Confirm that there is no oil, etc. on the surface of the paper feed roller or the separation pad.
3. When reassembling the timing belt (removed when taking cut the pick-up roller) pass it through the
upper side of the belt tensioner.
4. When installing the separation pad bracket to the copier, first free the paper stop lever by pushing
down the pick-up roller downwards.
Note 1:
Put the projection
into the bracket hole.

6. Periodic Maintenance
The bypass roller, separation pad and pick-up roller should be replaced every 60,000 copies.
7. Installation of Key Copy Counter
KN-1550K should be installed in the copier using 2 screws, but there is only one hole in the cover of
the 1560. With regard to this kit installation, make a hole for a screw with a cutter or a this thin driver
(a minus driver is better) in the bypass paper feed cover. (Only this part of the cover is thin.) (See
Illustration K.)

Content
Each increase by "1" causes the paper to
incline more.
In the 1560, when the above code 64 is set to "0", the copy speed from the bypass has been made
faster by using the key operation below. (As before, from approx. 8 cpm to approx. 14 cpm.)
In the usual bypass method, the optical system scan (total scanning), but in this mode offers A4/LT
scanning (half scanning).
<Key operation>
1. Set paper in the bypass guide. (Bypass paper feeding is selected.)
2. Press the "CASSETTE" key while pushing the "%" key. (The bypass symbol start flashing.)
3. Start copying by pushing the PRINT key.
When this mode is used, there are the following limits.
Page 10
BSI No. F97I037 Page 10
1. If the paper width in the feeding direction is 216 mm or over, the paper becomes jammed.
2. If thick sheets of paper is used, toner fusing may become insufficient. (especially for postcards).
3. When the bypass mode is changed to the cassette mode or when the bypass guide runs out of
paper, this mode is cleared.
When this mode is not used, set AD (08) mode/code 64 to 1". (At the time of shipment, it is set to
"0".)
10. Circuit diagram & DC harness Connection Diagram
This copier has different LGC circuit board and DC harness connection diagram than the 1550. The
LGC circuit and DC harness connection diagram have the icons given below added to it. The file
