What can I do if the Printer continuously rejects Cartridges?
If you are in Service Mode 1, the cover sensor is disabled. In order to test a new Cartridge set, the Printer must be powered OF and and ON again.
1Remove tape and align cartridges: One frequent cause of cartridge problems is that the user has forgotten to remove the tape from new cartridges Remove the tape
2Dirty pads: The connection between the carriage PCA and the cartridge flex connector is made by means of a gold bubble on the flex connector that touches a gold pad on the PCA The Carriage Test details ' page
492 includes a test of this connection When nozzle failures occur clean the flex contacts on the cartridge and in the Carriage
3Continuity Problem: Remove all the cartridges from the Carriage and try installing just the rejected cartridge If the cartridge is still rejected then replace the cartridge with a new one If the new cartridge is not rejected then check one by one if the other cartridges are rejected or not
4Faulty cartridge: Some black cartridges 564A with USE BEFORE dates of April 96 and earlier may have thin9film damage This means that the material used for channeling ink behind the nozzles can crack with aging When this happens ink seepage may cause many nozzles to fail eight or more Replace the black cartridge with one with USE BEFORE date of ay 96 or later
5If the Cartridges are not inserted correctly into the Carriage the Cartridges will be rejected ake sure that the springs that hold the Cartridges in the Carriage are not broken or misplaced
