A PostScript error rangecheck offending command a4tray occurs when the PostScript code contains an explicit command to select a certain supply cassette in the printer while the output device doesn’t support such a cassette.
Change the settings in the driver
- If the output device doesn’t use trays, it is highly likely that an incorrect driver is used. Make sure to select the correct driver.
- If you received a PostScript file containing such a setup, you can open the file in a word processor, find the A4tray command and simply delete the 3 or 4 lines of PostScript that relate to selecting a cassette. Save the file and try sending it again.
