The POSjet
1500 Printer uses Hewlett-Packard inkjet print cartridges. Unlike consumer inkjet print cartridges, the
®
HP print cartridge does not need to be capped when not in use. Consequently, the POSjet
1500 is ready to print at
all times. The HP cartridge does not need to be sealed. However, the inkjet cartridge must have periodic usage to
maintain its functionality. The printer does this by cleaning the excess ink from the face of the cartridge ("wiping")
and firing ink into a reservoir to clean the print jets ("spitting"). The printer performs these functions as
transparently to the host application as possible. However, the printer cannot perform these basic maintenance
procedures if the power to the printer is removed.
Do not unplug the printer from it's power source. Instead, turn the printer to the STANDBY/OFF mode by
pressing and releasing the * Button located on the front face of the printer. Doing this prepares the ink cartridges for
periods of inactivity. Turning the printer to STANDBY/OFF maximizes the amount of time that the ink cartridge(s)
can be left without being used. When the printer is turned to STANDBY/OFF, it can sit unattended for a period of
time. To bring the printer back out of STANDBY/OFF mode, simply press the * Button. This will bring the printer
into OPERATIONAL/ON mode, which should be confirmed by the
becoming illuminated.
Operating the Keypad Controls
The keypad contains 3 buttons and 6 indicator lights. The * Button is used in conjunction with the keypad controls
to perform operating tasks and is located on the front of the printer. The Open Cover Button is located on the left
side of the printer console. It is used to open the printer's paper cover.
