A laserPRO Spirit stopped accepting files after migration from a Windows XP direct LPT connection to a Windows 7 Professional 32-bit USB connection. The evidence does not establish a single root cause: firmware changes and the USB/driver migration occurred in the same troubleshooting sequence. Isolate the communication path before changing firmware again.
Record the Observed Configuration
| Item | Observed value or behavior |
|---|---|
| Laser firmware | 2.13 at the final reported state |
| Operating system | Windows 7 Professional, 32-bit |
| Printer driver | Spirit_32V3.75-02 |
| USB driver | USBSetup1.13-01 |
| Detected port | Virtual USB port 005 rather than GSS port0 |
| Earlier connection | Windows XP with a reported direct LPT connection |
Separate the Symptoms by Firmware State
With the initial USB configuration, the machine received a file but displayed PSL error 0 after Start was pressed; the additional codes were not recorded. After firmware 01.28 was installed, the system reportedly froze repeatedly. After firmware 2.13 was installed, it booted to “File was not received, please send again” and “Back,” but the F1 Back function and other menus were inaccessible.
These observations establish sequence, not causation. They do not prove that firmware 01.28 or 2.13 is generally defective, nor do they prove that Windows USB power management caused the fault.
Test the Windows USB Path
- Connect the laser and identify its entry in Windows Device Manager. If identification is uncertain, unplug and reconnect the USB cable while observing which entry disappears and returns.
- Open the identified device’s properties. If a Power Management tab is present, clear “Allow the computer to turn off this device to save power.” Treat this as a diagnostic test because USB power saving is only a proposed cause.
- Restart the connection test and send a file. Record whether the computer reports the device online, whether the laser acknowledges the file, and whether PSL error 0 returns.
- If behavior is unchanged, uninstall and reinstall the existing software and USB/printer drivers, then repeat the same test without changing firmware simultaneously.
Verify the Fault Boundary
Power-cycle the laser and observe the USB state without first reconnecting the cable. In the reported failure, turning the laser off made it appear offline, but turning it on did not restore the online state until the USB cable was unplugged and reinserted. If that behavior repeats, document it as evidence of a USB enumeration or driver-path problem; it still does not exclude a machine-side firmware fault.
A successful test requires more than an online indication: the computer must send the job, the laser must acknowledge receipt, its menu controls must respond, and Start must proceed without PSL error 0. Preserve the exact secondary error codes if the fault returns because they were missing from the original observation.
FAQ
Why does my laserPRO Spirit stay offline after power-up?
In the reported case, the device returned online only after the USB cable was unplugged and reconnected. Check the identified USB device’s power-management setting, then retest power-up without reconnecting the cable.
What does PSL error 0 mean on a laserPRO Spirit?
The evidence records PSL error 0 after Start but does not define it. Capture all accompanying codes before changing firmware or drivers so the error can be correlated with the failed stage.
Should I downgrade laserPRO Spirit firmware 2.13?
The evidence does not support a specific downgrade. Firmware 01.28 froze in the reported sequence, while 2.13 produced a persistent file-not-received state; isolate the USB and driver path before making another firmware change.
