Table 3-1. Printhead Troubleshooting (cont.)
ACTION:
LOOK FOR:
WHAT NEXT:
Check CWP Purge Performance:
6.
Check vacuum and decay time at metal
pipe using vacuum "T" during front panel
CLEAN cycle.
7.
f vacuum is less than 46 cm Hg at
metal pipe (LOOK FOR 6A), check vacuum
at pump side of vacuum module without “T”
during front panel CLEAN cycle.
8.
Locate source of CWP vacuum leak.
❑
6A. a peak vacuum reading during
purge:
Peak vacuum at metal pipe:
__________
❑
6B. the time it takes for the vacuum to
decay to 0 cm Hg:
Decay time:
__________
❑
7. peak vacuum at pump side of vacuum
module without "T" during front panel CLEAN
cycle.
Measured vacuum at pump:
__________
❑
8A. plugged tubing between CWP and air
solenoid or vacuum module.
❑
8B. misaligned CWP belts.
❑
8C. misaligned printhead-to-drum.
❑
8D. interference with printhead tilt
mechanism.
❑
6A. If less than 46 cm Hg (18 in Hg, 9
psi), go to ACTION 7.
If greater than 46 cm Hg, go to LOOK
FOR step 6B.
❑
6B. If decay time is about 6 seconds, go to
ACTION 10.
If there is no decay time (sudden
drop to zero), CWP gasket is bad. Go
to ACTION 9.
If decay time is less than
6 seconds, check metal and rubber
tubing for ink.
If decay time is much longer than
6 seconds, replace vacuum module.
❑
7. If less than 51 cm Hg (20 in Hg, 9.9
psi), replace vacuum module.
If greater than 51 cm Hg, go to ACTION 8.
❑
8A. Replace rubber or metal tubing and go to
ACTION 6.
❑
8B. Align belts and go to ACTION 6.
❑
8C. Align HTD and go to ACTION 6.
❑
8D. Repair mechanical interference and go to
ACTION 6.
Install NEW CWP:
9. Install new CWP. Do up to 6 purge cycles to
test performance.
❑
9. good CWP purge performance.
❑
9. New CWP may take 4-6 purges
before optimal performance. Go to ACTION
6.
Retest print quality:
10. Print Service Test Print 2: Weak and Missing
Jets.
❑
10. weak or missing jet(s).
❑
10.
If no weak or missing jets, repair is
complete. Print quality is OK.
If PQ not OK, go to ACTION 11.
Install NEW Printhead
11. Install a new printhead only after
completing previous steps.
Note:
If you have not replaced the CWP and
you're not confident the printhead is
defective, change the CWP.
12. Check printhead drive voltage.
13. Check for Service Required Errors.
14. Check CWP purge performance:
ACTION 6.
❑
11. left and right HTD adjustments are
equal at HOT adjustment.
Note:
Hot printhead adjustment must
be performed for good purge
performance and good print quality.
❑
12. Head Adjust setting of 128.
❑
13A. 13,004.43 or 13,020.41 errors:
etstack not heating as quickly as it
should.
❑
13B. 13,001.40, 13,002.41, 13,003.42,
13,017.46, 13,018.48 and 13,035.47.
❑
13C. 4,002.41 and 4,006.45 errors:
rinthead NVRAM all zeroes.
❑
14. good purge performance with NEW
printhead.
❑
11. If HTD adjustment is uneven from
side-to-side, CWP will not purge
properly. Adjust HTD and go to ACTION 12.
❑
12. If Head Adjust is not 128, set it to
128 and go to ACTION 13.
❑
13A. Readjust HTD: left or right side of
printhead is too close to drum. If error
reoccurs, replace printhead.
❑
13B. Reseat printhead ribbon cable
before replacing printhead.
❑
13C. Check printhead ribbon cable
before replacing power control board
(followed by printhead).
❑
14. If purge performance is good, go to
ACTION 10 to verify.
