Error

Image is skewed on the media
|
|
Cause
|
|
Skewed images are a result of incorrect
electronic registration. This can be due to one of the following:
- >>sys erin is set to “0“, disabling
electronic registration. The system cannot detect if the
plate is registered or not. Type >>set sys erin 1 and
>>set al prr 3 to re-enable electronic registration.
(Prr = plate registration retries, allows you to manually
correct plate registration.)
Note: For Trendsetter VLF Autoloader, >>sys erin must always be "1".
- >>sys erin is set to "1", but an electrical
short between the registration block and the drum fools the
system into thinking that the plate is registered. For
example, a small metal chip may be trapped between the
registration block and the drum.
- >>sys erin is set to "1", but dirt between the leading edge clamps and the plate causes
the plate to move from registration when the roller comes
down.
Note: The LED light will always be on during plate loading, whether or not electronic registration is disabled ("set sys erin 1" or "set sys erin 0").

Solution

Troubleshooting Steps:
- Check that the parameters are set correctly: >>set sys erin
1 and >>set al prr 3.
- Use a multimeter to measure the resistance between the
registration block and the drum strap. There should be high
resistance or infinity '∞' (no beep if your meter is
set for "Beep".). If an electrical short exists,
it can be caused by one the following:
a/. A small metal chip is trapped between the
registration block and the drum. Vacuum the registration
block area and clean it with alcohol. If you still have a
short, then remove the leading edge clamps to clean the
pocket between the registration block and the drum (this
procedure can take up to one hour). If a short still exists,
continue to 'b' and 'c'.
b/. The capton between the registration block and the
drum pocket is damaged. Contact the Response Center to request that somebody
be sent from Vancouver to replace this part.
c/. The insulated screw used to attach the registration
block to the drum is damaged. Contact the Response Center to request that somebody
be sent from Vancouver to replace this part.
- Use “TEC ON” to open the leading edge clamps, then clean the
clamp edges all the way across the drum. It is important for
each clamp to have full surface contact with the plate.
(If small hard particles stick to the clamp's bottom
surfaces, the plate will be held by point contacts instead
of the full surface. When the roller goes down, the plate may pull back from the
registration block, causing the image to be skewed.)
