Remove any media already loaded into the plotter before performing the calibration.

Place a sheet of polyester film over the top of the plotter for approximately 10 minutes to let itstabilize to the environmental conditions. Use a sheet approximately 24 x 36 inches (61 x 91 cms).Roll media may also be used. When using polyester film, load it with the matte(dull) side down.

8-20 Troubleshooting C4705-90000

Certain plotter failures that can occur will prevent the plotter from reaching the “STATUS /Ready for Media” state. If one of these problems occurs, switch the plotter OFF. Press and holddown the ENTER and the UP ARROW buttons while switching the plotter ON. This will allowaccess to the service tests.

! !

!

If no button is pressed for 1.5 minutes, the front panel will return to the “Status” menu.

In some cases a quick press of a button may not be recognized by the processor. When pressing abutton, be sure to press it deliberately and all the way to the bottom of its travel.

If the plotter hangs up during a test, switch the plotter OFF and restart from step 1.

In some cases the plotter may revert to the “STATUS” message upon exiting a test. To return tothe service menu, perform the above steps.
