Solving Carriage Stall Conditions
A carriage stall error condition occurs if the printer detects a problem with the movement of the print cartridge cradle along the printer carriage. In order to exit from a carriage stall, you have to turn the printer off.
The Change Cartridge light is on when an HP DeskJet 400 printer detects a service station motor stall. The service station is the part of the mechanism below the print cartridge when the print cartridge is at the right end of the mechanism (the “home” position). It serves to cap the print cartridge so that the nozzles will not dry out. In order to exit from a service station motor stall, you have to turn the printer off.
Caution
Do not attempt to manually move the print cartridge or print cartridge cradle from the home position (right end of the mechanism). The mechanism locks the print cartridge cradle in the home position, and attempting to slide the cradle or print cartridge in the locked position may damage the printer.
