(The currently set adjustment value is displayed on the copy
quantity display.)
13) Press the start button. (Make a copy with the document cover
open.)
(A copy is made.)
14) Measure the rear edge void area.
If the distance between the paper rear edge and the copy image
rear edge is not 2.5
±
1.5mm, change the set value and press the
start button.
The adjustment value can be set in the range of 0
∼
99.
15) Use A4(11
×
8.5) paper to make a test chart as shown below.
16) Set the test chart made in procedure 15) on the SPF tray.
17) Use the copy image mode select key to select the SPF mode
image lead edge reference position (image scan start position)
adjustment mode. (The auto/manual copy mode lamp lights up.)
18) Press the START button. (A copy is made.)
19) Measure the distance between the paper lead edge and the
copy image lead edge.
If the copy image lead edge is cut away, suppose the virtual
image and measure the distance.
If the distance between the paper lead edge and the copy image lead
edge is not within 0
±
1.5mm, change the adjustment value and per-
form procedures 16)
∼
19) again.
20) Cancel the simulation 50-1 mode.
(The following procedures are for SPF mode copy rear edge void
area adjustment.)
21) Set the test chart made in procedure 15) on the SPF tray.
22) Make a copy in the SPF copy mode. Check the copy rear edge
void area.
(Check that the distance between the paper rear edge and the copy
image rear edge is 2.5
±
1.5.)
If the above condition is not satisfied, perform the following proce-
dures.
23) Enter the simulation 26-44 mode.
24) To change the print density, change the adjustment value with
the figure UP-DOWN key and press the START button. (The
adjustment value is stored.)
(Adjustment range: 0
∼
8, Default: 4)
When the adjustment value is changed by 1, the distance is changed
by about 1mm.
25) Cancel the simulation 26-44.
Repeat procedures 21)
∼
25) until the specification in procedure 22)
is satisfied.
(The following procedures are for the FAX SPF mode copy rear edge
void area adjustment.)
26) Set the test chart made in procedure 15) on the SPF tray.
27) Enter the simulation 46-12 mode.
28) Make a copy in the FAX SPF print mode and check the void
area.
(Check that the distance between the paper rear edge and the copy
image rear edge is 2.5
±
1.5 mm.)
If the above specification is not satisfied, perform the following proce-
dures.
29) Enter the simulation 26-47 mode.
30) To change the print density, change the adjustment value with
the figure UP-DOWN key and press the START button. (The
adjustment value is stored.)
When the adjustment value is increased, the copy rear edge void
area is increased.
(Adjustment range: 0
∼
8, Default: 4)
When the adjustment value is changed by 1, the distance is changed
by about 1mm.
31) Cancel the simulation 26-47.
Repeat procedures 26
∼
31) until the specification of procedure 28)
is satisfied.
(Note)
Use SIM 50-10 to adjust the main scanning direction image posi-
tion

Troubles caused by improper work
1) If the void area is less than the specified level, the transfer roller,
the fusing roller, the separation pawl, and the paper trnsport sec-
tion are dirtied with toner.
As a result, print paper is dirtied and paper jams are generated.
