The external account module is required to use a "external account application" on the machine.
An external account application can be used in "external authentication mode" or "external count mode". When external 
authentication mode is used, the login screen is retrieved from the application when the machine is started. When a job 
ends, a job notification screen is sent to the application to enable counts to be kept for each authenticated user.
When "external count mode" is used, the login screen is not displayed when the machine is started. Only a job result 
notification is sent to the application. User authentication by the external account application cannot be used, however, 
the external account application can be used in combination with the internal account function.

To enable an external account application in the Web pages of the machine, click [Application Settings] in the 
administrator menu frame, and then [External Applications Settings] and [External Accounting]. Configure settings for 
the external account application in the screen that appears. To make the settings in the Web page take effect, restart the 
machine.

The two modes for using an external account application operate as explained below.

When the [Enable Authentication by External Server] checkbox is selected in "External Account Setting" of "Sharp OSA 
Settings" in the system settings (administrator), the machine enters external authentication mode. When the machine is 
powered on in external authentication mode, the machine accesses the external account application and displays the 
login screen. The login screen also appears when the [Call] key is touched to run a job in the job status complete screen. 
(The login screen does not appear if the user has already logged in by the normal method.)
The [JOB STATUS] key can be pressed while the login screen appears to show the job status screen. To return to the 
previous state, press the mode select key.

If the login screen fails to appear or the application does not operate correctly, the machine may also stop operating 
correctly. In this event, it is recommended that you quit external account mode from the Web pages of the machine. For 
more information, see [Help] in the Web pages.
If it is necessary to forcibly terminate external account mode using the operation panel of the machine, follow the steps 
below.
Press the [SYSTEM SETTINGS] key and change "External Account Setting" in the system settings (administrator). After 
changing the setting, restart the machine.

When only the [External Account Control] setting is enabled in "External Account Setting" of "Sharp OSA Settings" in the 
system settings (administrator), the machine enters external count mode.
Unlike external authentication mode, when the machine is started in "external count mode", the login screen of the 
external account application is not displayed. Only the job result is sent to the external account application. External 
count mode can be used together with the user control function of the machine. (External count mode can also be used 
when the user control function is disabled.)

The user control function of the machine cannot be used in external authentication mode. 
However, "User Registration", "User Count Display", "User Count Reset", "User Information Print", and "The Number of User 
Name Displayed Setting" can be used.

This chapter explains how to clean the machine and replace the toner cartridge or waste toner box.

To ensure that the machine continues to provide top quality performance, periodically clean the machine.

If the document glass, document backplate sheet, or automatic document scanning area becomes dirty, the dirt will 
appear as dirty spots or coloured lines or white lines in the scanned image. Always keep these parts clean.
Wipe the parts with a clean, soft cloth.
If necessary, moisten the cloth with water or a small amount of neutral detergent. After wiping with the moistened cloth, 
wipe the parts dry with a clean dry cloth.

Do not use thinner, benzene, or similar volatile cleaning agents to clean the machine. These may degrade or discoloured the housing.

If coloured lines or white lines appear in images scanned using the automatic document feeder, clean the scanning area 
(the thin long glass next to the document glass).
To clean this area, use the glass cleaner that is stored in the automatic document feeder. After using the glass cleaner, 
be sure to return it to its storage position.

If black lines or coloured lines appear even after you have cleaned the document glass and document feeder, use the 
charger cleaner to clean the main charger that charges the drum.

For the steps to follow when letting the waste toner box 
fall forward, see step 3 of "

" (page 48).

Pull out the knob as shown in Figure 2.

Push the knob as shown in Figure 2.

There are a total of 4 places to be cleaned in the machine 
as shown in Figure 1.

Push the waste toner box firmly in until it clicks into place.

If paper misfeeds frequently occur when feeding 
envelopes, or thick paper through the bypass tray, wipe 
the surface of the feed roller with a clean soft cloth 
moistened with water or a neutral detergent.

If lines or other dirt appear on the scanned original when 
the automatic document feeder is used, wipe the surface 
of the roller with a clean soft cloth moistened with water 
or a neutral detergent.

• If this does not solve the problem, pull the knob out and push it back in 2 more times.

• When pulling and pushing the knob to clean the charger, pull and push the knob slowly from one end to the other.

• Touching the waste toner outlet or the waste toner box may soil your hands and clothes. Exercise caution when cleaning 

the charger.
