Sometimes, when the printhead is quite damaged, running the hard-clean routine twice helps to recover its performance. New printhead is rejected If the printer will not accept a new printhead, try the following steps in sequence: 1. Ensure that the printhead was correctly stored in its orange cap. 2. Ensure that the electrical contacts are clean. 3. Run the primer system diagnostic. 4. Exchange the printhead with the printhead of the same color in the other row. 5. Assume that the printhead is faulty, and try another one. 6. If no printhead works in that slot, call your service representative. Printhead cleaning roll errors You should not touch the printhead cleaner roll except when you need to replace it. When the printhead cleaning roll reaches its end, it should be replaced. Always do this by following the Internal Print Server wizard. See Replace the printhead cleaning roll, filters, and spittoon on page 161. Any handling of 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.
