Adjustment Program Cannot Detect the Printer
Confirm exact-model compatibility, USB connection, selected port, Windows detection, and program build before changing service values.
Common symptoms
The adjustment program opens but shows no printer.
The program reports communication or selected-port errors.
A nearby model works, but the exact model does not appear.
What to do
- 1
Verify that the program explicitly supports the exact model code—not only the same printer family.
- 2
Connect by direct USB when the program requires it and wait for Windows to finish detecting the printer.
- 3
Open the program’s model/port selection and choose the correct device when available.
- 4
Close other printer monitoring or service applications that could lock the port.
- 5
If the model is absent from the program build, do not select a similar model as a shortcut; use the correct package or request the exact file.
Check the exact printer model
Open the model library before downloading or running service software. Compatibility can differ between nearby model numbers and regional variants.
