Replace a defective printhead
Attention: Always store printheads near the printer or allow the printheads to
adjust to the printer's environmental conditions before you insert them into Océ
TCS500 printer.
Attention: Do not open the top cover when you are not in the wizard. When you
open the top cover outside the wizard, the system produces a long, uninterrupted
audio signal. When you open the top cover during printing, the printer stops and
the red LEDs on the printer operator panel remain illuminated. After you close
the cover, the print is cut. Then the whole print job is restarted.

the system asks you to load the correct media. When calibration is possible with one
of the rolls, the system automatically uses the correct media roll. When calibration
is possible with both rolls, use the lower softkeys to select the roll to use.
Press the key for 'Next'.
