Servo ControlĆSystem Failures
MediaĆAxis (XĆAxis) Shutdown
In the case of a mediaĆaxis shutdown, try one or more of the following corrective actions:
Clear any binding in the mediaĆaxis mechanics due to a media jam. (Do not pull the
media along the carriage axis. Doing so could break the mediaĆsensor flags.)
Remove the two screws that attach the driveĆroller gear to the drive roller. This should
enable you to manually spin the drive roller. If it does not, the roller is probably jammed.
Perform the servo/encoder service test to check for problems with the mediaĆaxis motor
encoder and main PCA.
CarriageĆAxis (YĆAxis) Shutdown
In the case of a carriageĆaxis shutdown, try one or more of the following corrective actions:
Clear any binding in the carriageĆaxis mechanics due to a media jam.
Turn the plotter off. This should enable you to manually move the carriage along the
carriageĆaxis. Check for any areas where the carriage may be binding.
Ensure that the double pulley, small drive belt, small belt tensioner, main belt, main idler,
and carriage bushings are in correct working order.
Perform the servo/encoder service test to check for problems with the servoĆfeedback and
motor drive systems.
Frequent Cartridge Failure
Remove Tape and Align Cartridges
One frequent cause of cartridge problems is that the user has forgotten to remove the tape
from new cartridges. Remove the tape and perform a cartridge alignment.
Damaged Encoder Strip
Another cause of apparent frequent cartridge failure may be a damaged encoder strip. If the
small slots on the strip are damaged, the plotter cannot position the carriage correctly during
cartridge checking. Try replacing the encoder strip.
Incompatibility between Carriage and Firmware
In combination, cartridge carriage C2847Ć60071 (carriage PCA C2847Ć60125) and plotter
firmware A.01.00 destroy the cartridges. Update the plotter firmware and replace the
cartridges. (Details chapter 9 Problms Corrtd by irmwar Rlas A.01.01.)
