Loss of Registration Between Frames
Loss of accuracy between the frames of a completed marker plot may indicate
a loss of registration during frame advance. Check the following items to en-
sure that the plotter is setup properly:
• Make sure the frame sensor is enabled in the Control Center (model
600Ae only) or check the Frame Gap (see the Operation section for more
details). If the frame sensor is OFF mark the check box and send settings
to the plotter so that it functions properly.
• The frame/panel size may be mismatched between the plotter and the
design software. Check that the frame size in the software is equal to or
lower than the default panel size of 46” (116.8 cm).
Registration problems can also arise from the paper slipping under the
pinchwheels or from other tracking problems. If everything appears to be
setup properly see Tracking below.
Tracking
Tracking is the process that controls the media motion over the platen and
assures accurate lines and frame matching. If the paper is slipping under the
pinchwheels or is not aligned, plotting quality and frame registration are
degraded. To resolve tracking difficulties try the following suggestions:
• The paper must be installed correctly. See the Operation chapter for more
details.
• Inspect the paper for wrinkles or folds. Never use any paper that is folded,
wrinkled, or torn in any way.
• Check the take-up shaft to see if the roll of completed marker plots ex-
ceeds the height of the paper guide flanges (greater than 600 yards). If the
take-up roll diameter is greater than the paper guide flanges the paper
will have to be removed before sending the next plot file. See Removing
Completed Markers from the Take-Up Roll in the Operation chapter.
• Reducing the speed and acceleration settings in the Control Center can
resolve some tracking problems.
• Make sure the pinchwheels are spaced across the paper as outlined in the
Operation chapter.
• The inner pinchwheels must not be positioned over the bearings in the
drive shaft because paper tearing and bunching will occur.
• Check to make sure that the plotter is level. See the Setup chapter.
• The chart wheel pressure on the drive shaft creates an impression on the
marker. The underside of the completed marker plot will always have
visible drive tracks which should be identical. If one drive track is more
pronounced or markedly different than the others there may be a chart
wheel or drive shaft problem.
• The paper may be slipping because debris has accumulated on the drive
shaft preventing proper paper traction. Inspect and clean the drive shaft.
Refer to the Preventative Maintenance chapter.
• Contact an Ioline distributor or Ioline Customer Service if damaged equip-
ment is causing tracking difficulty or if the plotting quality problem can-
not be resolved.
Poor Line Quality
If the marker plot line quality is uneven try the following suggestions in
order:
1. Use the keypad force knob to select a pen force that produces adequate
line quality.
2. Increase the Pen Down Delay.
3. Replace the pen with a new one.
4. Adjust the plotting speed values in the Control Center software.
5. Plot on a higher quality paper.
6. Refer to the Operation chapter to check that the pen is recommended by
Ioline.
7. Check the white plotting strip under the pen. Have it replaced if it is
damaged.
8. Contact an Ioline distributor or Ioline Customer Service for further help.
