9) Set the printer name.
<1> If you want to change the printer name, enter a new name
in the space provided.
<2> If the program displays, “Do you want your Windows-based
programs to use this printer as the default printer?”, check
“Yes”.
<3> Click the [Next] button.
10) Make the appropriate settings for your environment.
● When using print sharing, choose “Shared” and enter a share
name. If necessary for your environment, select Windows 95
from the list of operating systems.
● If you are not using shared printing, choose “Not shared”.
After making the settings on this screen, click the [Next] button.
11) Print a test page by clicking the [Finish] button.
Note: If you check “No” and click the [Finish] button, the printer
does not print a test page after the installation.
● The printer driver installation begins.
12) When the test page is printed properly, click the [Yes] button.
● The printer is ready for printing.
E. Changing Printer Configuration Settings
After installing the printer driver use the procedure in this section to
change the printer configuration settings. Also refer to the print driver
help for more information.
1. Click the Start menu, point to “Settings”, and choose “Printers”.
2. Right-click the appropriate printer and choose “Properties” from-
the menu.
3. Click the Configuration tab and change the printer settings.
7. Expansion memory installation
Memory expansion realizes the following effects.
● Increased processing speed of outline fonts or complex graphic data.
● Shorter release time from a printing job of the computer.
● Allows high resolution printing.
● Complex data can be printed without data loss error or memory full
error.
Extend the pawls, insert an expansion memory, and engage the pawls
with the notches.
8. Print server card installation
Remove the dummy cover, insert the print server card into the connec-
tor of the printer PWB and fix it with the screw of the dummy cover. At
that time, cut off the notched section in the rear cabinet with nippers.
(Use nippers so that the cut surface is flat.)

Note:
● Use a digital multi-meter with an internal resistance of 10 MΩ
or more.
1) Set the digital multi-meter range to DC700V.
2) Put the test rod of the digital multi-meter on the developing bias
voltage output check pin.
3) Turn on the power.
4) Adjust the adjustment volume VR31 so that the output voltage is
within the specified range shown below.

(2) Grid bias voltage adjustment
Note:
● Use a digital multi-meter with an internal resistance of 10MΩ
or more.
1) Set the digital multi-meter range to DC700V.
2) Put the test rod of the digital multi-meter on the grid bias voltage
output check pin.
3) Turn on the power.
4) Adjust the adjustment volumes (VR51, VR52) so that the output
voltage is within the specified range. (The voltage is outputted in
the grid bias high output mode during warming up, and in the grid
bias low output mode after completion of warming up.)
5) Adjust the adjustment volume VR51/VR52 so that the output volt-
age is within the specified range shown below.

(1) Image lead edge position adjustment (SIM 50-1/SIM 50-10)
a. OC image lead edge position adjustment
Note: In advance to this adjustment, the sub scanning magnification
ratio adjustment must be performed.
1) Set a scale on the OC table as shown below.
2) Make a copy.
3) Check the copy output. If necessary, perform the following adjust-
ment procedures.
4) Execute SIM 50-1.
5) Set the OC lead edge position set value (Exposure display
<AUTO> ON) to “99.”
The OC image scanning start position is shifted inside the docu-
ment edge.
6) Set the main cassette lead edge void adjustment value (Exposure
display <PHOTO> ON) * to “1.”
The lead edge void becomes the minimum.
7) Set the print start position value (Exposure display <EXP1> ON)
to  “99” and make a copy.
The print start position is shifted inside the document edge.
8) Measure the image loss R of the copied image. Enter the set
value of the image scanning lead edge position (Exposure display
<AUTO> ON) again.
● 1 step of the set value corresponds to about 0.127 mm shift.
● Calculate the set value from the formula below.
99 - R/0.127 (mm) = Image loss set value <R: Image loss meas-
urement value (mm)>
Example: 99 - 4/0.127 = 99 - 31.5 = about 67
Note: If the set value is not obtained from the above formula, per-
form the fine adjustment.
9) Measure the distance H between the paper lead edge and the
image print start position. Set the image print start position set
value (Exposure display <EXP1> ON) again.
● 1 step of the set value corresponds to about 0.127 mm shift.
● Calculate the set value from the formula below.
99 - H/0.127 (mm) = Image print start position set value <H: Print
start position measurement value (mm)>
Example: 99 - 5/0.127 = 99 - 39.4 = about 59
Note: If the set value is not obtained from the above formula, per-
form the fine adjustment.

10) Set the main cassette lead edge void adjustment value (Exposure
display <PHOTO> ON)* again.
● 1 step of the set value corresponds to about 0.127 mm shift.
● Calculate the set value from the formula below.
B/0.127 (mm) = Lead edge void adjustment value <B: Lead edge
void (mm)>
Example: When setting the lead edge void to 2.5 mm:
2.5 /0.127 = about 20
Note: If the set value is not obtained from the above formula, per-
form the fine adjustment.

b. SPF image lead edge position adjustment
1) Set a scale on the OC table as shown below.
Note: Since the printed copy is used as a test chart, put the scale
in parallel with the edge lines.
2) Make a copy, Then use the copy output as an original to make an
SPF copy again.
3) Check the copy output. If necessary, perform the following adjust-
ment procedures.
