For Tray Selector to be able to control your printers, the paper and tray selections within the printer driver need to be set to the defaults which are normally automatically selected when you add a printer driver using the Add/Remove Printers option in your Control Panel.
It could be that while trying to resolve the issue prior to using Tray Selector, you may have changed the printing preferences to choose a specific media type or paper tray within your driver which is now overriding the commands sent by Tray Selector.
The easiest way to resolve this is by choosing one of the two following methods:
- Reinstall the printer driver and leave all settings as they are by default
- Right click on your printer and choose printing preferences. Then choose Paper/Quality and make sure the Paper Source and Media type are both set to Automatic. The wording of these options will vary between printers, but you should be able to easily find the relevant settings for your printer.
It is also possible that your printer itself has been set up to always select a particular printer tray and ignore any commands that are sent to it. Some printers are also set up to change tray depending on the media type sent to them. The settings vary depending on the printer, but often it is possible to check these settings by scrolling through menu items on the printer’s small LCD display. Normally, changing back to the factory default settings will solve your problem.
