HP DesignJet 5000 Series Printers Service Manual
Service Station
The Service Station consists of a linear motion mechanism with a 
chassis containing one PrintHead Cleaner (PHC) for each printhead. 
Attached to the Service Station chassis, one optical drop detector 
provides nozzle check functionality.
Print Head Cleaner (PHC)
The PHC case is the main structural part of the replacement module. 
It is the part that the customer handles and contains the other sub-
components:
n
Wiper to remove ink residue and external debris from the 
Printhead.
n
Spittoon to receive ink from the firing Printheads when the 
nozzles are cleared of viscous plugs and any loose debris.
n
Cap to prevent the Printhead nozzles from drying out while the 
Printer is idle.
n
Handle and Printable Label to remove and install the PHC. Also, 
the printer uses the handle top surface to recognize if the PHC is 
present or not.
In addition, there is a built-in mark on the handle (a vertical hole) to 
calibrate the Service Station (Scan-axis) if there is a problem and 
the EEROM is erased.
