2 Reinstall the Ink Delivery System as follows:
1 Remove the four printheads from the carriage. On the front panel you
will see the four squares representing the printheads flashing.
2 Clean the electrical contacts using the Ink Cleaner Part Number
C6247A.
3 Reinstall all the printheads, one by one, checking on the front panel
that the squares representing the reinstalled printheads are steady.
D DO NOT INSERT THE NEXT PRINTHEAD UNTIL THE
PRINTER HAS ACCEPTED THE CURRENT PRINTHEAD.
D If, even after the electrical contacts have been cleaned, the
printhead is not accepted REPLACE THE COMPLETE INK
SYSTEM (Printhead/Head Cleaner/Ink Cartridge) for this color.
D If, after inserting a NEW Ink System, the printhead is not
accepted, the problem may be with the printer. Replace the
Carriage Assembly ' 8-42.
4 If you have reinserted the four printheads and the printer has
accepted them continue reinstalling the head cleaners.
5 Remove and reinstall the ink cartridge valves, one by one, checking
on the front panel that the squares representing the reinstalled ink
cartridge are steady.
D If the ink cartridge is not accepted, REPLACE THE COMPLETE
INK SYSTEM (Printhead/Head Cleaner/Ink Cartridge) for this
color.
D If, after reinserting the NEW Ink System, the ink cartridge is not
accepted, the problem may be with the printer. Make sure that the
Refill Assembly cable is not damaged and is correctly connected to
the Interconnect PCA. If the cable is correctly connected and is not
damaged then replace the Refill Assembly ' page 8-55.
3 If the problem is fixed, but it reappears frequently, contact a HP dealer
for a replacement (the Ink System may be damaged.)
