Technical Notes
Other useful facts
ID/Key is an optional hardware key encoded with a serial number that is compared prior to every
print job with a number in the printer’s NVRAM. If there is a mismatch, the printer is disabled.
ID/Code is a field-alterable password stored by both the printer dirver and the printer itself. It pre-
vents use of the printer with a PC not having the same
ID/Code. Check the ID/ Code if the printer fails
to function, and everything else looks fine. Reference Technical Note 8.
Password protection blocks access to some of the lower level printer adjustment screens. Not to be
confused with ID/Code. Reference Technical Note 8.
Interlock “cheating” is not something the operator should do, but as a technician you will need to run
the P640i with the main cover open. Cut a narrow strip of plastic from a used CR-80 card, fold it,
then push it into the interlock slot in the center wall. When the ALARM light goes out, the interlock
switch is closed.
Restore printer configuration
You can return the printer to its previous backup configuration be pressing the
PRINT, RIBBON and LAMINATE buttons on the front panel at the same time as
the printer is powered up. But first, remove the color ribbon! This is termed a
“three button reset,” page TN1-4
Flip station
Any time you open the main cover, for whatever reason, be sure that the flip
station is fully down before the cover is closed. Do this by gently pushing down
at the back of the flip carrier.
Correction to this User Guide
Most fasteners used in the P640i have U.S. standard threads. Printers manufactured after
October 2004 use Torx® socket head screws in locations other than set screws on pulleys and
gears. In addition to a standard set of small hex drivers, you will need the following Torx drivers:
T10, T15, T20 and T25.
