Color Kit  (260-2963)        Colour Print Test         Faxback Doc. # 3634
JP 1000

The print test enables you to make sure that the print head is working 
properly by checking the efficiency of the nozzles and their electrical 
contacts.

For a description of the procedure for running the print test, see the 
printer user guide.

The test printout contains:

   A nozzle testing scale consisting of three coloured sections
   (yellow, magenta and cyan) with all the nozzles numbered (from 1 to 51)

   A rectangle for testing the electrical contacts

   Three bands each consisting of three full-colour lines to test the
   nozzles in a uniform way

   A repetition of the scale in which any gap corresponds to a defective
   nozzle

   A repetition of the rectangle, which is cyan if all the contacts are
   correct and magenta if a least one contact is missing

The print test also indicates problems caused by the print head, e.g. 
missing lines.  Should these occur, adjust the print head as follows:

   Press the INSTALL CARTRIDGE key:  the print head will move to the
   center of machine.

   Remove the print head from the carriage]

   Clean the print head contacts and the printer contacts using the brush
   supplied in the case.

   WARNING:  If there is ink on the contacts, do not use the brush
             otherwise you could dirty it permanently; use absorbent paper
             or similar material.

   DO NOT TOUCH THE NOZZLES WITH THE BRUSH OR ANYTHING ELSE!

   Reassemble the print head and pres the INSTALL CARTRIDGE key:  the
   print head will return to its rest position after a long purging cycle.

   Run a print test to check that the adjustment has been successful

Should the print head not work properly again you may follow the procedure
described below, as a last resort before replacing it and under the 
condition that you DO NOT CARRY IT OUT SYSTEMATICALLY as it could cause 
damage to the print head:

   Soak a paper handkerchief in water and wring it slightly

   Remove the print head from the carriage

   Press the handkerchief against the print head with the nozzles pointing
   downwards

   Repeat this operation several times using different parts of the
   handkerchief until the nozzles are perfectly clean

   Reassemble the print head

   Run a print test

If this does not prove successful either, replace the print head.
