Table 2-1. Troubleshooting the Marking Head (continued)
PROBLEM CORRECTIVE ACTION
Indentation depth is inconsistent in a particular
area of the marking window.
1. TMP4100, TMP4150, TMP4155: The coiled Drive Air tubing may be
kinked or restricted when traversing. Inspect the tubing from the valve to
the manifold for cracks, restrictions or crimps in the tubing.
2. TMP4100, TMP4150, TMP4155: Loose or incorrectly mounted head
cartridge.. Check for a loose cartridge, leaking air, or a cartridge mounted
incorrectly.
3. TMP4100, TMP4150, TMP4155: Worn cartridge, or excessive dirt/oil in
the Drive Air making the pin stick. Inspect the pin cartridge for excessive
"blow by" air.
Remove the cartridge, push the pin into the cartridge, and release it in a
vertical position (pin down). The pin should drop freely. If not clean with
isopropyl alcohol and try again.
The indentations within the characters are not
placed accurately.
• The marker or material to be marked may be moving relative to each other
during the marking cycle. In order to assure a high quality mark, it is
important that there is little or no relative movement between the marker
and material being marked.
The marked characters are wholly or partially
garbled or skewed.
1. TMP4100, TMP4150, TMP4155: The incorrect pin type may be entered,
causing a slip. Sharper pins require slower marking speeds, and with
softer material, may hang up in the product being marked. Verify that the
correct operating parameters have been entered. On new installations, try
a slower marking speed.
2. A slip may have occurred while marking due to an interference. The
material being marked may have raised portions which are being struck
by either the impact pin or the cartridge. A “dry run” with the pin retracted
may verify the possible interference.
3. Excessive vibration of the marker in the plane of the marking surface,
normal to the indentation forces, may have caused a slip Due to the
inherent nature of step motor driven systems, there is the possibility of
exceeding the holding force of the motors with impulse forces caused by
vibration. Ensure the mounting of the marker will not promote vibration in
the same plane as the cartridge base/frame traversing components.
4. If the cartridge base/frame mechanism does not fully travel to the Home
position, it may reach the end of travel before the marking is complete
Verify that the full range of travel in both X and Y directions is achievable
by jogging the unit to its extreme positions. If full travel is not possible,
check the flag in that direction for proper location. Check for interference.
Verify there is no internal binding of parts or tubing.
5. The impact pin may be momentarily sticking into the target material,
resulting in excessive drag and slip. The deeper that the impact pin
penetrates the target material, the longer it takes to retract from the
material. This is mostly due to the increased energy transfer into the
target.
Marking time is too long
• The marker is supplied with the factory parameters set to provide the
highest degree of quality and best practical speed for all font selections
and resolutions. The parameter values may be changed, giving you the
ability to customize the setting for your particular application.
• In most cases, marking times will be reduced if you increase the marking
speed. Using the marking system software, display the Marker Properties
and adjust the marking speed parameter, as required, to increase the
speed settings.
• Marking times may also be reduced by decreasing the pixel density (using
Continuous mode), changing the print mode (from Continuous mode to
non-continuous, dot matrix mode), or changing the character font and/or
character size.
• Change the settings as required to better meet your needs, but ensure the
quality of the resulting mark is acceptable.
