php给出错误提示--打开流失败: HTTP请求失败!HTTP/1.1 505 HTTP版本不支持

我试图从一台惠普扫描仪上获取ScannerStatus，但却发现了一些错误。

fopen($scannerstatus1,"r");
我得到的错误如下
Warning: fopen(http://10.0.0.106:80/eSCL/ScannerStatus): failed to open stream: HTTP request failed! HTTP/1.1 505 HTTP Version not supported in /var/www/html/eSCL/ScannerStatus/index.php on line 14
readfile($scannerstatus1);
