TROUBLESHOOTING Overview 56
3.1.3 Status Monitor does not operate
This section describes the procedures for checking printers when the Status Monitor
suddenly can no longer be used to check the printer status, even though the Status
Monitor has been operating normally before.
Table 3-3. Status Monitor Error Checking Point
Step Check Point Remedy
1 Use the
adjustment
program to
check the 08H
address (IEEE
1284.4 for
parallel) for the
EEPROM.
The relationship between the IEEE 1284.4 for Parallel setting status
and the setting values is given below.
00H : Auto
(Status cannot be sent to the computer when the printer has
an error)
01H : On
(Default: Status can be sent to the computer even if the
printer has an error)
02H : Off
(Status cannot be sent to the computer regardless of the
printer status)
To reset, use the Dump function of the adjustment software to
rewrite the setting to the default (01H). Refer to Chapter 5 for
details.
NOTE: The Stylus PHOTO 950 has a default setting function, but
there is no function available for the customer to change the
setting for the 08H address. Even if the default value (01H)
is changed to 00H or 02H, the EEPROM data may become
corrupted, so even if the communication problem is fixed,
there is a high possibility that the various adjustment values
may be distorted. Because of this, all parameter electrical
adjustments should be carried out afresh. Refer to Chapter 5
for details.
2 Use the
adjustment
program to
check the 09H
address (IEEE
1284.4 for
USB) for the
EEPROM.
The relationship between the IEEE 1284.4 for Parallel setting status
and the setting values is given below.
00H : Auto
(Status cannot be sent to the computer when the printer has
an error)
01H : On
(Default: Status can be sent to the computer even if the
printer has an error)
02H : Off
(Status cannot be sent to the computer regardless of the
printer status)
To reset, use the Dump function of the adjustment software to
rewrite the setting to the default (01H). Refer to Chapter 5 for
details.
NOTE: The Stylus PHOTO 950 has a default setting function, but
there is no function available for the customer to change the
setting for the 09H address. Even if the default value (01H)
is changed to 00H or 02H, the EEPROM data may become
corrupted, so even if the communication problem is fixed,
there is a high possibility that the various adjustment values
may be distorted. Because of this, all parameter electrical
adjustments should be carried out afresh. Refer to Chapter 5
for details.
3 Has the printer
driver been
installed
correctly?
If the problem cannot be reproduced at the Service Center, get the
customer to reinstall the driver and re-check.
