Transportable ink jet printer apparatus

An easily transportable ink jet printer apparatus, comprising:

• a) a chassis that includes a paper storage tray movably mounted to the chassis between printing and carrying positions, an ink jet print head having nozzles for dispensing ink, the print head being movably mounted to the chassis along a travel path, wherein the ink jet print head has a parked position when not printing in which the nozzles are capped to prevent clogging of the nozzles by dried ink;
• and
• b) a paper tray locking linkage that enables a user to safely transport the chassis, the linkage including a handle that is movably mounted upon the chassis between locking and unlocking positions, wherein the locking linkage holds the paper tray in a secured carrying position when the handle is moved to the locking position.

An easily transportable ink jet printer apparatus, comprising:

• a) a chassis that includes a paper storage tray, a paper exit tray, an ink jet print head having nozzles for dispensing ink, the print head being movably mounted to the chassis, and a paper handling mechanism that moves paper from the storage tray to the print head to the exit tray, wherein the ink jet print head has a parked position when not printing in which the nozzles are capped to prevent clogging of the nozzles by dried ink;
• and
• b) a locking mechanism on the chassis that includes a handle that is movably mounted to the chassis between carrying and printing positions, wherein the handle locks the paper exit tray when moved to the “carrying” position.
