A printhead has overheated A printhead may overheat for several reasons. ● The room temperature may be too high. ● The printhead may be suffering from blocked nozzles. You may be able to cure this problem by cleaning the printheads (see Clean the printheads on page 25). ● The printhead may be suffering from an internal failure, in which case it must be replaced. A printhead has damaged the substrate When a printhead touches and damages the substrate, the most likely cause is excessive heat. Therefore, try decreasing the drying temperature. For information on how to adjust printer settings, see the User's guide. Incorrect printhead cleaning roll errors You should not touch the printhead cleaner roll except when you need to replace it. Any interference with the roll may prevent the printer from keeping track of roll usage, in which case you may see spurious error messages, and a printing job may be cancelled unnecessarily.
