No. Question Answer
Q1 Registration information of the device (E-RDS) is once
deleted from the UGW server, and is re-registered after that.
If a communication test is not
carried out, then device information on UGW becomes
invalid. When registration of the device (e-RDS) is deleted from the
UGW, the status will be changed to the communication test
not completed because related
information has lost from a database. Therefore, device
information will also become invalid if that condition persists
for seven days without carrying out the communication
test. Hence, to avoid the invalid condition, carry out the
communication test.
Q2 The communication test with the UGW server results NG! The comunication test might become NG in the following
cases.
- 1. Name resolution was failed due to an incorrect host name
or DNS server has been halted.
- 2. Network cable is blocked off. Network cable is broken.
- 3. Proxy server settings are not correct.
Q3 Could you describe the timing of data transmitting from the
device (e-RDS) to the UGW, and what data size is sent to the
UGW? The schedule of data transmitting, and the start time are
determined by settings in the UGW side. The timing is once
per 16 hours by default, and counter data size is maximum
1400 bytes.
Q4 Can I turn the device power off during the device (e-RDS)
operation? While operating the device (e-RDS), the power of the printer
and network equipment such as HUB must be ON. If power
OFF is needed, do not leave it OFF for a long time.
An error such as "Device is busy, try later"could occur if the
power supply of network
equipment is made prolonged OFF.
