To fix the error, first you will need to change your default check laser/inkjet printer to a printer that is ONLINE, can print from other applications, and has a printer tray setting.

MultiCHAX will usually display this error message when the printer is offline or unavailable. Also, do not select the MultiCHAX Virtual Printer as the printer.

  1. Close MultiCHAX (use the task manager) or right click on the MultiCHAX icon on the taskbar to close
  2. Click on the Start Menu
  3. Type REGEDIT in the search field and select the regedit.exe application
  4. Find HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\MultiChax (for 32-bit machines: HKEY_LOCAL_MACHINE\SOFTWARE\MultiCHAX)
  5. Right click on the delete the FOLDER keys that start with the word MICR

  6. Open the C:\MultiCHX\Temp folder and delete the files that start with AAA

  7. Restart MultiCHAX

NOTE: Restarting the MultiCHAX application should select your default printer automatically .
