If the barcode on the front is missing or isn't readable by the scanner or the iPad camera, you have a few options. If you can read the numbers, you can type in the number starting with 40196 manually either on your computer or your iPad. If you can't read the numbers or if the barcode is missing, check the inside back cover to see if the number is on a sticker or hand written there. If you still can't tell, you can send the book down to me to investigate.
If you want me to replace unreadable barcodes, I am happy to do that. Just send the book down to me.
If it says "This item is already available," then the book has already been checked in (or was never checked out in the first place). Go to "Check Out Items" and look up the student (either by name or student ID number), just to make sure there isn't another book assigned to them.
If an error message appears that says “This item has been marked as lost,” you can ignore it. Checking the book in changed its status from lost to available, nothing else is required.
If an error message shows that a student is owed a refund, you can ignore it. The system will send me an email about any refunds that are due for found items.
