HP DesignJet 5000 and 5500 Series Printers Service Manual
Replace Message "xx16 Replace" for ALL Printheads
During Replacement
During Printhead replacement, the message "xx16 Replace" can
appear for ALL the Printheads due to a firmware bug.
Clean the Printheads and the Carriage interconnects (refer to page
9-6,
Carriage Interconnect Wiper
) and reseat the failing Printheads.
Refill Information (DesignJet 5500 Series Only)
Ink-Level Sensing (ILS) Out of Control
Two situations exist that could trigger an ILS Out of Control:
HP Ink Cartridges deliver more ink than the expected 680cc
– Ink Cartridges refilled with non-hp ink.
– ILS coils become stuck (rare).
Non-hp hardware detected in the Ink Delivery System.
Each one of these situations could potentially damage the printer’s
Ink-Tube System and Printheads. However, since we cannot tell for
sure if damage to the printer will occur we cannot prevent a
customer from printing. What we can do is warn the customer of
possible damage, but not stop the printing altogether.
Ink Cartridge Delivers Too Much Ink
The following information explains the front panel message flow:
