Temperature not
changing fast
enough.
Chamber is slow
to heat up.
1. Status-Details: Check to see if current envelope
temperature is above 72C before starting a
model.
2. Status--Details: Check to see if envelope
temperature set point is 77C. If not, toggle power
switch.
3. Check heaters, chamber fans, and heater cables.
4. Check AC input. Verify that no extension cords or
power strips are attached to the system.
5. Check AC output from PDB to chamber heaters.
Check AC cables. Replace PDB.
6. See error codes 14-39, 14-40, 14-133.
Liquefier won’t
heat up (its cold).
Use HP Designjet
3D Diagnostic
Software to check
to see if the temp
is going over
90C. If temp is
above 90C go to
next section
1. Liquefier T/C may be crushed. Test using meter. If
crushed, reading will be 0 Ohms between pin 1
and ground.
2. If head board with LED’s is present, check model
and support 120VDC LEDs at head board.
• If both model (upper) and support (lower) LEDs
are illuminated, head heater is bad. Replace
head.
• If only the model LED (lower) is illuminated,
replace the 120VDC power supply
• If only the support LED (upper) is illuminated,
replace the power distribution board
3. If head board with LED’s is not present, use volt
meter to check for 120 VDC at head board.
• If 120VDC present at both model and support
side, heater is bad. Replace head.
• If no 120VDC at support side, replace
120VDC power supply.
• If no 120VDC at model side, replace power
distribution board.
4. The umbilical cable to the heater is broken or has
a bad connector.
5. Check AC input. Verify that no extension cords or
power strips are attached to the system.
6. Check that DL18 on the PDB is lit. If not 120VDC
circuit maybe bad - replace PDB.
7. Monitor DL23 (M) and DL24 (S). LED's should turn
on when head is commanded to heat. If not lit -
check 120VDC, if absent replace PDB (model) or
120VDC AUX (support).
8. Check the thermocouple and heater connectors.
Liquefier is warm
but doesn't reach
operating
temperature.
1. Check AC input. Verify that no extension cords or
power strips are attached to the system.
2. Liquefier heater has high resistance, should be
175 to 216 ohms. If incorrect replace head.
3. The umbilical cable has an intermittent
connection. Replace Umbilical Cable.
4. Replace the Head Board.
