8TROUBLESHOOTING 8.29The machine does notappear on the scannerslist (continued)• Check if the MFP port is not busy. Since functionalcomponents of MFP (printer and scanner) share the sameI/O interface (MFP port), the situation of simultaneousaccess of different "consumer" application to the sameMFP port is possible. To avoid possible conflicts, only oneof them at a time is allowed to gain control over thedevice. The other "consumer" will encounter "devicebusy" response. This can usually happen while startingscan procedure, and appropriate message box displays.To identify the source of the problem, you should openMFP ports configuration and select the port assigned toyour scanner. MFP port's symbol /dev/mfp0 correspondsto LP:0 designation displayed in the scanners' options, /dev/mfp1 relates to LP:1 and so on. USB ports start at /dev/mfp4, so scanner on USB:0 relates to /dev/mfp4respectively and so forth sequentially. In the Selectedport pane you can see if the port is occupied by someother application. If this is the case, you should wait forcompletion of the current job or should press Releaseport button, if you are sure that the present port's owneris not functioning properly.The machine doesn't scan • Check if a document is loaded into the machine.• Check if your machine is connected to the computer.Make sure if it is connected properly if I/O error isreported while scanning.• Check if MFP port is not busy.
