Installing Adobe Flash Player

If a patron asks to have the Adobe Flash Player installed, here’s how to do it:

  1. Go to
  2. Uncheck any optional offers and click install
  3. When prompted, save the file on the computer and run it (look for the file in the downloads folder)
  4. Agree to any prompts in the installation process (including error messages; it will work anyway)
  5. Restart the patron’s brower(s)

That should do it. If you have any questions, ask Megan, Scott or Andy.

Printer Error 79

Occasionally, the public printers will get an “error 79” message on them. This means that there is something wrong with the print job that the patron has sent to the printer. It is imperative that you identify the PC from which this print job error originated. Also, it is important to note the website or type of file that the patron was trying to print in order to troubleshoot this issue.

The only way to “fix” this issue is to restart the PC upon which this print job originated.

Please get Andy immediately when this issue occurs.

Comprise said that there is another way around this problem, and that is to go to a “kiosk” type Print Release Station, as we already have for wireless printing. The patron would send a print job, then go to the Print Station (laptop) to release the print job. This way, we can identify and kill the offending job easily.

SAM Printing

If system repeatedly states patron account is inactive, check the following:

  1. Is the patron’s card expired?
  2. Does the patron owe more than $9.99 in fines?
  3. Does Koha’s patron record list a birth date?
