FAQ: ITM8400 InfoDent® Marker
If you are unable to find an answer to your question, please contact our sales or service departments.
Q: My pins are getting dull. Can the pins be re-sharpened?
A: Yes, the pins can be re-sharpened. InfoSight offers a pin re-sharpening service and an optional pin sharper device.
Please contact the sales department for additional information regarding these
options. If you wish to re-sharpen the pins yourself, please refer
to the Pin Reconditioning section of the Operations and Maintenance manual.

Q: I have a pin that is sticking. How do I free it up?
A: First determine if the pin is sticking inside or outside the head cartridge. Next refer to the Operations and Maintenance manual for
additional details.

Q: What should I use to lubricate the pins?
A: The ITM8400 InfoDent® marking head can be used in both lubricated and un-lubricated applications, depending on the product being
marked. If InfoSight has determined that your application requires
lubrication, the preferred lubricant is a 10W, misting type, non-detergent oil
such as machine tool oil.

Q: My mark is not deep enough. How do I get a deeper mark?
A: The depth of the mark is generally increased by either increasing the drive air pressure, or by increasing the pin throw distance.
It is also possible to increase the mark depth by switching to a larger
(heaver) pin although this may require a major head redesign.

Q: My mark is too deep. How do I reduce the depth of the mark?
A: The depth of the mark is generally reduced by either reducing the drive air pressure, or by reducing the pin throw distance. It is
also possible to reduce the mark depth by switching to a smaller (lighter) pin
although this may require a major head redesign.

Q: I am getting a Y (or X) axis home limit fault on the operator's
terminal. What does this mean?
A: When you place the marker online, it performs a homing operation to seek its reference limits in both the X and Y axes. If either axis
fails to find its respective reference limit within a certain period of time,
then that axis generates a home fault which is displayed on the operator's
terminal. This can be caused by any of the following.
1) The most likely cause would be a physical
obstruction that keeps the axis from traveling far enough to reach the sensor. 2) A failed sensor on the limit/temperature board mounted in the
head. 3) Failure of the axis "flag" to properly occlude
the limit optical sensor. 4) A wiring problem with the head
cable. 5) Failure of the stepper driver board where the limit
inputs are terminated. 6) Failure of the stepper motor and/or
driver to move the head to the reference location. 7) The head
cable might not be properly attached.

Q: My cycle time is too slow. How do I speed up the
marker?
A: There are many ways to speed up the print cycle, each having its own advantages and disadvantages. First, consider lowering the density
of the characters by changing the font to 5x7. Second, make sure
you are using the Matrix method of printing. Next, if you are
using the User Defined character height, use the calculator to compute an
exact number of characters per pin. Next, lower the on-time parameter in
marker setup to reduce the amount of time it spends firing the
pin. Next, lower the vector delay parameter in marker setup to
reduce the idle time between moves. Finally, adjust the motor ramp
tables to obtain a faster move profile for the stepper motors.

Q: How can I get continuously formed characters in a reasonably
short cycle time?
A: The Continuous method of printing prints fully formed characters using one pin at a time which can be too slow for some
applications. To get similar results in a reasonable time,
consider using the InfoWarp method of printing. This method also
provides fully formed characters, but since all pins are firing together, the
cycle time is greatly reduced.

Q: Why is the marker refusing to recognize the start print command even
though it is online?
A: The marker will only recognize the start print (either the digital input or the menu command) if it is in Auto Mode. Make sure the
Auto input is on.
