Problem:
When connecting a different scanner model in your SCSI daisy chain, an error message such as the following appears; ‘‘The EPSON scanner is not connected.’’
Cause
When you sent the SCSI inquiry command, the
computer checked the scanner’s model name in the
Vendor Unique Parameter.
Solution
When checking the Vendor Unique Parameter, only check the following underlined items:
| (B1−B4) |
...‘‘EPSON’’,20H,20H,20H,SCANNER,20H, |
|
(B5, A5) |
This ensures that information on a particular model name is not checked by your program.
Problem:
Although you have attached a new scanner capable of a higher resolution, you cannot achieve that resolution when scanning.
Cause
Your program is still using the scanning resolution settings you obtained from the previous scanner model.
Solution
Use the ESC I command to obtain the scanning resolution values each time you scan.
