Carriage (Integrated Printhead and Ink) : 

HP Restricted 10 Carriage (Integrated Printhead and Ink) The carriage: holds the cartridges connects timing circuitry in the printer to the actual nozzles on the cartridges completes the electrical circuit Aerosol is the spray resulting from splattering of ink as it hits the paper. It may soil the electrical contacts. Customers can clean the contacts on the cartridges and the carriage with a clean, lint-free cloth using distilled or bottled water (power should be off, printer unplugged).

Docking Station/Spittoon (Integrated Printhead and Ink) : 

HP Restricted 11 Docking Station/Spittoon (Integrated Printhead and Ink)

Docking Station/Spittoon (Integrated Ink Tank and Printhead) : 

HP Restricted 12 Docking Station/Spittoon (Integrated Ink Tank and Printhead) The docking station (a.k.a. “capping” station, a.k.a. “service” station) serves as a resting place for the cartridges while not in use. Its purpose is to seal the cartridges while in the printer so air can’t dry out the printheads. Cartridges are serviced in the docking station. A small amount of ink is spit through the printheads into the spittoon to clean the nozzles before and during print jobs to maximize the print quality. The docking station is located on the left or right of printer To ensure that cartridges return to the docking station, always turn the printer off before unplugging it.

Encoder Strip & Carriage Rod : 

HP Restricted 15 Encoder Strip & Carriage Rod Encoder strip Carriage rod

Encoder Strip : 

HP Restricted 16 Encoder Strip The encoder strip (translucent tape) uses light to let the printer know where the carriage is on the carriage rod. Sometimes aerosol residue gets on the encoder strip and blocks the light transfer. Carriage can forget where it is - symptom is carriage slamming into the sides of the printer. Connection between encoder strip and printer is fragile – therefore HP does not encourage customers to clean or remove it. Agents should troubleshoot using documentation, then send unit in for service (if necessary).
