errors. After installing the printhead, you may
get one of the following service errors due to mis-adjustment or cabling problems:
■
4,002.41 and 4,006.45 errors: printhead NVRAM all zeroes. If the data cable
between the power control board and the printhead is not plugged in properly or
damaged, this error will occur. Reseat or replace the data cable.
■
13,001.40, 13,002.41, 13,017.47 or 13,018.48 errors: Reseat or replace the
printhead ribbon cable before replacing the printhead. Perform a cap/wipe/purge
with the new printhead.
■
13,003.33 and 13,035.47 errors: A heater is running away. If the gray data cable
is not making a good connection, the incorrect data will be sent to the main
board. Reseat or replace the printhead ribbon cable. If the problem continues,
replace the power supply and then the printhead.
■
13,004.43 or 13,020.41 errors: The printhead jet stack is not heating as quickly
as it should. Readjust the left or right head-to-drum adjustment; the printhead is
too close to the drum, which prevents it from warming up (840 only). If the error
reoccurs after the adjustment, replace the printhead.
■
13,001.40 and 13,017.47 errors: An open left and right jet stack thermistor.
Reseat or replace the gray data cable. If the error reoccurs, replace printhead. If
the new printhead gives the same error, replace the power control board.
■
13,002.41 and 13,018.48 errors: A jet stack thermistor appears to be shorted.
Reseat or replace the gray data cable. If the error reoccurs, replace the printhead.
If the new printhead gives same error, replace the power control board.
■
13,035.47 Replace the power supply.
