It seems that the printer prints an automatic information page. In most cases, this can be deactivated in the printer settings, either via the printer menu or the printer software on your computer. Look there for an option that controls the printing of test or status pages. If this does not solve the problem, resetting the printer to the factory settings may help. Alternatively, you can also contact the manufacturer's support team, as we are unfortunately unable to carry out remote diagnostics.

According to the manufacturer, TK-5480 and TK-5490 toners fit, e.g. these here: https://www.digitec.ch/de...
