Servo Control7System Failures

Media%Axis (X%Axis) Shutdown

In the case of a media7axis shutdown, try one or more of the following corrective actions:

DClear any binding in the media7axis mechanics due to a media jam. (Do not pull the media along the carriage axis. Doing so could break the media7sensor flags.)

DRemove the two screws that attach the drive7roller gear to the drive roller. This should enable you to manually spin the drive roller. If it does not, the roller is probably jammed.

DPerform the servo/encoder service test to check for problems with the media7axis motor encoder and main PCA.

Carriage%Axis (Y%Axis) Shutdown

In the case of a carriage7axis shutdown, try one or more of the following corrective actions:

DClear any binding in the carriage7axis mechanics due to a media jam.

DTurn the plotter off. This should enable you to manually move the carriage along the carriage7axis. Check for any areas where the carriage may be binding.

DEnsure that the double pulley, small drive belt, small belt tensioner, main belt, main idler, and carriage bushings are in correct working order.

DPerform the servo/encoder service test to check for problems with the servo7feedback 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 C2847760071 (carriage PCA C2847760125) and plotter firmware A.01.00 destroy the cartridges. Update the plotter firmware and replace the cartridges. (Details ￿ chapter 9 w Probl￿ms Corr￿￿t￿d by ￿irmwar￿ R￿l￿as￿ A.01.01.)
