Resetting NVRAM

ink clog in the vacuum tube leading to the cap/wipe/purge assembly.
If the vacuum does not bleed off, then the air valve is not opening
properly, the 7-mil orifice (a part of the vacuum/pump assembly) is
blocked or the vacuum tubing may be clogged. If the printhead is hot,
such a condition can allow ink to be sucked into the vacuum system
tubing. If the vacuum takes longer than 4 to 6 seconds to bleed off,
the air valve solenoid or the cap/wipe/purge assembly may be
defective.
If the vacuum bleeds off too quickly, the tubing will be blocked or the
cap/wipe/purge assembly may be defective; check to see if the cap/
wipe/purge assembly is not sealing properly to the faceplate. Check
that the cap/wipe/purge assembly is properly positioned by
performing the " "Cap/Wipe/Purge Assembly Belt Adjustments."
Resetting NVRAM returns most the printers's PostScript NVRAM-
stored parameters, including those of the network card, to their
factory defaults, except the copy count (for images processed through
the image processor), the Adobe firmware serial number, the usage
profile and the authorization codes. Print engine NVRAM values are
not changed by the following procedure.
Select NVRAM parameters are not reset by the standard resets found
in the front panel or PC-based diagnostics. These include copy counts,
panic counts, ink density calibrations, and boot parameters among
others. If particular parameters become corrupt, the printer may not
operate correctly or may not recover. If NVRAM corruption of this
type occurs, the most effective method of correcting the problem is to
replace the offending NVRAM part with a new part.
To reset the printer to its factory-default values, follow this procedure:
1. If possible, print the Configuration Page for a record of all the
printer's port settings and other customer-unique settings.
2. Enter the Service Support menu.
3. Press and hold the Left arrow button.
4. While holding the Left arrow button, press the Select button
to enter the hidden service menu.
5. Scroll to the menu item Reset NVRAM and press the Select
button.
6. Scroll to the menu item Reset NVRAM and Reset Printer
Now and press the Select button again, to reset NVRAM.
Alternately, you can also use the PC diagnostics to selectively return
either the print engine NVRAM contents or the PostScript NVRAM
contents to their factory default values as shown in the following
illustrations.
