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:
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. To test this follow the steps shown in the picture below
If you require any further assistance, please don’t hesitate to get in touch.
Once you are sure your data is correct, do not click any of the buttons to merge the document to a new document printer or fax as you would normally do. Instead, click your Tray Selector button. The printer setup utility will automatically recognise that the document is a mail merge and display the dialog box shown below:
If you click ‘Yes’, then each merged letter of your document will be printed using your Tray Selector settings. Clicking ‘No’ will just print the current document (i.e. unmerged), and clicking ‘Cancel’ will print nothing.
Notice that in mail merge mode, Tray Selector will print just one copy of your documents, even if you have set a different number of copies to be printed, and it will not print any extra advanced copies.
