PaperCut – Ricoh Embedded Manual

6 Known Limitations and Security

6.1 Limitations on SDK v4 (or higher) devices

6.1.1 Fax Tracking Limitations

Due to limitations in the Ricoh device, the PaperCut application is only notified of fax events

when the user is logged in to the device. Depending on the size of the fax, it may take a

number of minutes to deliver and receive the successful notification. If the user has logged

out, the fax will not be logged.

This is an unfortunate limitation in the Ricoh device SDK, and we are working with Ricoh to

resolve this.

To mitigate this problem, PaperCut will disable the automatic logout timeout when a fax job

is started, and then restarts the time-out when the fax is received. This means that faxes will

be logged OK as long as the user does not press the "Logout" button.

If another user logs in and then the fax transmission is completed, the fax may be charged

against this new user.

It is recommended to change the Fax transmission mode to "Immediate TX". This is

discussed in section 2.2.8.

6.2 Limitations on SDK v2 devices

The Ricoh SDK 2.x devices provide a limited environment for copier control applications like

PaperCut. The following limitations exist on Ricoh SDK 2.x devices:



No zero-stop support (i.e. the ability to stop copying in progress when a user runs

out of credit).



No support for card-based authentication (i.e. no support for USB card readers).



No support for tracking Faxing or Scanning.



Copy settings from the previous user may not be cleared when the next user logs in

(e.g. Copy counts, color, etc). This is a limitation of the SDKv4 devices that does not

allow 3

party applications to tell the device when the user logs out. It is

recommended to set the reset timer to a short time to reduce the impact of this issue.

6.3 Bypassing the System

It is important that the administrators take care to prevent users from bypassing the system

and directly accessing the copier. Likewise it's also important that administrators know how

to bypass/disable the system if direct copier access is required – say to change advanced

system settings. Administrations should take the following precautions:



The copier's built in admin password should be changed and always kept secure.



The power and network cable should be securely connected. The system is

designed to be robust and record copier usage if the power is lost during copying, but

it is possible to start copying before the embedded application starts after restarting

the copier.

To disable the embedded application to allow for uncontrolled access to the copier, see the

Uninstall section of this document.
